The advantages of using Acron Hi and Acron Express

Some existing users highlight the advantages of Kemdent's Acron Hi and Express for different indications

Kemdent manufactures a wide range of tried and trusted laboratory products, but sometimes it can be difficult to decide which option to choose for any specific indication. This article will highlight the main features and benefits of Kemdent's Acron Hi and Acron Express acrylics as identified by just some of their many advocates in the UK.

 

Acron Hi - ideal for high quality results

 

Acron Hi is a true high impact strength acrylic which is perfect for the provision of high-quality denture work. It utilises Kemdent's unique Multi-Matrix Technology to produce dentures that are highly resistant to breakage and fracture. It produces a soft packable 'dough' that is ideal for all processing protocols including injection moulding systems because it can be processed using a rapid 30-minute or longer curing cycle in boiling water.

Once mixed, Acron Hi exhibits a relatively soft 'dough stage' compared with its competitors, which tend to be rubbery in consistency. This makes it easier to pack into moulds because it flows more easily and smooothly, an advantage if you are using an injection moulding process. Using Acron Hi ensures a better fit and requires less post-processing work to finish the denture. It also exhibits an increased stiffness, after processing, which makes it easier to trim and polish for most technicians. Finally, many other acrylics can be cured in just 20 minutes but may contain a high level of residual monomer, which can result in allergic reactions and reduce strength of the finished prosthesis. By ensuring a lower level of residual monomer the technician can minimise the risk of allergic reactions and produce dentures that are stronger and less likely to fracture because of increased cross-linking. They can control the level of residual monomer by always ensuring they use the correct powder to liquid mixing ratio. The level can also be reduced by using a slow cure overnight. Tests show that Acron Hi exhibits a much lower level of residual monomer compared with its competitors. Acron Hi is supplied in 'Light Pink Veined' and Original Veined' shades.

 

Acron Express - for busy commercial laboratories 

Acron Express is a new super-fast dough, heat-cured denture base acrylic designed for the manufacture of full or partial dentures, and is ideal for busy prosthetic laboratories and urgent cases. It takes just seven minutes to reach the dough stage, so laboratories can start packing jobs much sooner. What's more, once it has reached the dough stage, Acron Express stays packable for longer because it has an extended working time of at least 30 minutes at room temperature, allowing laboratories to process more jobs at the same time without loss of quality. Then it can be processed using either a rapid (20 min) or longer cycle in boiling water.

Acron Express produces dentures with exceptional high strength and a high lustre finish. It is easy to trim and polish. This superfast dough acrylic is available in 'Light Pink Translucent' and 'Pink Veined' shades.

Acron Express does not just save technician time and money, when it is used correctly with a good wax-up technique and high-quality denture teeth it will create a denture that offers strength, a more accurate fit, excellent true-to-life appearance and overall comfort for the patient, giving the patient the confidence to smile again.

 

User feedback

This is what some of Acron Hi's and Acron Express' existing users have to say:

John McKay, Dentures Direct, Glasgow

" I've been using Acron Hi for about two years, prior to that I used Enigma Hi and I use it for all my dentures now. I particularly like how cleanly it comes out of the moulds, which saves me time during the final processing stages. I also like the fact that Acron Hi appears to be significantly harder and has a higher flexural strength than Enigma Hi, another very important consideration"

Martin Waterson, Rax Lane Dental Laboratory, Bridport

"I started using Acron Hi for my private and independent dentures in 2001, prior to that I used Lucitone. I particularly like the working time, colour because it is slightly darker and it's better value for money. Compared to Lucitone, Acron Hi is a bit firmer in consistency and is easier to process"

 

David Spinks, CDT, Bramerton

"I use both Acron Hi and Express depending upon the clinical situation. I mainly use Acron Hi for partial dentures, though I also use it for some of my full/fulls. I began using it in about 2000, but before that I used Lucitone 199. I particularly like the way Acron Hi bonds to the teeth and its colour. It has a longer dough stage and working time than Lucitone which makes it much better for trial closures. Once processed Acron Hi is easier to finish and polish and you can achieve a much higher polish, which I think is an advantage. It also has a much better shade because it is not orange like Lucitone 199. Before starting to use Acron Express, in 2000, I used either Metrodent or QC20, for most of my cases. I particularly like its light veined colour and the fact that you can achieve a high polish afterwards"

Kemdent's Eco-friendly Modelling Wax

Users highlight the properties of the ideal modelling wax and the benefits of Kemdent's Anutex Eco in particular

Peter Smith, Elm Dental Laboratory, Wisbech and James Michael, Pinewood Dental Laboratory, Aberdeen, are just two of the technicians who have started using Anutex Eco within their Laboratories. This article highlights the features and benefits of the ideal modelling wax and why they believe Kemdent's Anutex Eco fulfills them all.

 


Using the right modelling wax can be the difference between your ability to provide your clients with the dentures they want and expect or not. It can also be the difference between a more relaxed working life for you, with real job satisfaction, or real frustration.

 

 

 

It is generally accepted that the properties of an ideal modelling wax are as follows:-

  • High strength and rigidity at mouth temperature.
  • Wide softening range above mouth temperature - ideally it should have a primary softening temperature of between 35°C and 41°C.
  • Easily mouldable in the softened state, without flaking, cracking or tearing.
  • Low thermal contraction.
  • Easily carved at room temperature without flaking or chipping.
  • Little change in properties on melting and re-solidification.
  • Supplied in sheets of consistently reliable thickness - 1.5mm thickness is the industry average, which is the optimum thickness for the palate of the final denture.
  • No residue on boiling out
  • Appropriate colour - though this is a matter of opinion for both a Technician and Dentist.
  • Good value for money.

 

If a modelling wax has the above thermal properties, it will remain stable so that it does not distort in the patient's mouth or during transport to and from the surgery. Whereas a seemingly less expensive wax which deforms at mouth temperature can end up costing you money in terms of lost time, for example readapting  inaccurate bite registrations or distorted wax try-ins etc. Other factors to consider are whether the teeth stay in place after the wax has cooled down. With less stable modelling waxes this is often not the case, resulting in more lost time. Similarly, are the teeth easy to reposition? This will be the case with more stable material, but not necessarily with others.

 

Another important quality is the modelling waxes response to pin-flaming and polishing afterwards. Premium quality waxes will pin-flame extremely well, taking on a very smooth appearance. This results in a high quality appearance. This results in a high quality finish, which can then be buffed up using cotton wool and cold water for enhancement, giving a brilliant mirror-like finish.

 

Associated Dental Products have been manufacturing their premium quality Anutex and Tenatex modelling wax since 1922. Now they have extended their range of modelling waxes with Anutex Eco and Tenatex Eco. These products were developed to offer a more ecologically-friendly alternative to their tried and trusted Anutex and Tenatex modelling wax ranges. They offer very similar handling and mechanical properties, but with much more ecologically-friendly manufacturing processes, processes that save over 30% of energy consumption.

 

How have they achieved this?

 

Modelling waxes are surprisingly expensive to manufacture because the process consumes a large amount of energy. However, Associated Dental Products Limited, Swindon, have been collaborating with the Manufacturing Advisory Service (MAS) and the Improve Your Resource Efficiency Service (IYRE) to develop  more ecologically-friendly way of manufacturing modelling waxes. Utilising their wax manufacturing expertise and energy efficiency funding secured from the IYRE, the result has been the new  Anutex Eco and Tenatex ranges, which are believed to be the worlds first eco-friendly ranges of modelling waxes. Consuming 30% less energy to manufacture, they believe they are not only better for the worlds environment, but will also enable them to offer an even more competitively priced product range, whilst retaining the high standards of their market leading Anutex and Tenatex modelling waxes in terms of physical and handling properties.

 

What do your colleagues think?

 

Having evaluated Anutex Eco for several months, this is what Peter Smith and James Michael said about Anutex Eco.
Peter Smith said

" I started using Anutex Eco in June (2013), having previously used Anutex. I like Anutex because it is a smoother wax to use, warming easier than most other waxes. It is very easy to carve and not at all sticky to handle. I find that Anutex Eco is slightly softer and less rigid than Anutex, which I think is an extra advantage. It also softens at a slightly lower temperature, which is another benefit. I've been told by dentists that it is easier to heat the bite blocks, which saves them time. I also find it easier to mould and carve, which is another big advantage because of the time I save. However, the thermal contraction properties and consistency appear to be about the same, which means that there is no loss in stability and set-ups don't drift as the wax cools down, again saving me valuable Laboratory time and inconvenience. It also boils out cleanly, without leaving any residue. Finally, I really like the pink shade of the Anutex Eco, which is in fact virtually the same shade as the Anutex, because it is not too red, which I've heard some patients find disturbing because they think their final dentures will have the same unnatural appearance."

James Michael said

"I previously used to use Anutex (Blue Label), but started using Anutex Eco in June (2013). I find it is slightly softer, which I think could be a significant advantage in the winter, otherwise both products are very similar regarding the softening range of temperatures, mouldability, thermal contraction properties, consistency, thickness of sheets, boiling out properties and shade"

PracticeSafe Soak the ideal impression material disinfectant

Belinda Mayoh BSc and James Holder BSc from Associated Dental Products Ltd, Swindon, describe the ideal qualities for an impression material disinfectant

 

First the boring bit

On page 42 of The Department of Health’s Decontamination Health Technical Memorandum 01-05: Decontamination in primary care dental practices it clearly states that all impressions, prostheses and orthodontic appliances must be “decontaminated in a multi-step process to be conducted in accord with the device or material manufacturer’s instructions.

PracticeSafe Impression SoakImmediately after removal from the mouth, any device should be rinsed under clean running water. This process should continue until the device is visibly clean. All devices should then receive disinfection according to the manufacturer’s instructions. This will involve the use of specific cleaning materials noted in the CE-marking instructions. After disinfection, the device should again be thoroughly washed. This process should occur before and after any device is placed in a patient’s mouth. If the device is to be returned to a supplier/Laboratory or in some other fashion sent out of the practice, a label to indicate that a decontaminated process has been used should be affixed to the package.”

In reality this means that every time a Dentist takes a dental impression it must be thoroughly rinsed, disinfected and rinsed again before it is sent to you at the Laboratory. Likewise when you send the crown, bridge, denture or whatever other type of appliance you have manufactured within the laboratory it must be similarly disinfected and rinsed by the Dentist before it is placed in the patient’s mouth. If the appliance is then returned to the laboratory, for whatever reason, the same cycle must be repeated both before sending it back and before reinserting it into the patient’s mouth at the next appointment. This protocol must be repeated until the patient leaves the Practice with the final restoration or appliance. In between times, you will similarly be rinsing and disinfecting the impression or device upon receipt within the laboratory and before sending it back to the Practice. That’s a lot of rinsing and disinfecting!

Impression placed in a bag

Unfortunately a lot of the impression materials currently in use, especially alginate and polyether impression materials, are very moisture sensitive and so can become swollen and distorted if they remain in contact with water for too long.

Similarly, some of the disinfectants currently in use are supplied in either a powder presentation, which needs to be thoroughly dissolved if it is to have the manufacturer’s recommended concentration for effective disinfection, which may not always happen in reality, or alcohol sprays where there is an obvious health risk associated with vaporised spray, may be even incorporated bacteria etc. Consequently a burst of pressure from a spray can expel potentially harmful bacteria into the Laboratory environment, which can then possibly settle upon the surrounding surfaces and later come into contact with staff, causing a serious risk of cross contamination and infection.

The water that the impression is rinsed in must also be considered. If it is hard water, containing various calcium and magnesium impurities, these can be deposited on the surface of the impression acting as a barrier between the impression surface to be disinfected and the disinfecting agent itself. It is also well documented that these impurities reduce the effectiveness of some disinfecting chemicals, themselves, by forming chemical bonds and essentially deactivating them.

Therefore the ideal Impression Material Disinfectant should have the following properties:-

Meet all the requirements of HMT 01-05 etc with regard to the disinfection of impression materials, prostheses and orthodontic appliances

- Safe to use – containing no allergenic or components hazardous to health

- Short working time – to avoid excessive water contact

- Easy to use

- Liquid rather than powder presentation – easy to mix in the correct proportions

- Effective in hard water

- Cost effective

There are now products on the market which, when used in the appropriate concentration in an ultrasonic bath to maximise contact with the impression material’s surface, require only 3 minutes immersion time. This is dramatically less than the 10 minutes recommended by the manufacturers of other products. This means that the risk of alginate and polyether impressions becoming distorted due to the water absorption is minimised. It also saves time for Technicians, who are often in a hurry and do not want to waste time waiting around while an impression soaks for the right duration, often resulting in inadequate disinfection.

ImpressioninaUltrasonicBath

These new products frequently contain different active ingredients. For example, they may contain a blend of Benzalkonium Chloride, Didecyldimethyl Ammonium Chloride and Borax. Benzalkonium Chloride is extensively used in First Aid Kits for the treatment of cuts, cold sores and blisters, but it has been tested and approved for use in the Food Industry (1), consequently it is safe for use within the Dental Industry too. Didecyldimethyl Ammonium Chloride provides an additional bacteriostatic and bactericidal effect. Finally, Borax or Sodium Borate is a naturally occurring mineral compound which helps disinfect the impression surface due to the formation of Hydrogen Peroxide. It also acts as a natural water softener, acting against the calcium and magnesium impurities found within hard water, thereby boosting the disinfecting efficiency of the Benalkonium Chloride and Didecyldimethyl Ammonium Chloride. The combination of all three makes the impression material disinfectant effective against bacteria (including MRSA) and fungi (including yeasts) and lipid enveloped viruses.

Frequently they are also manufactured without any of the degreasers or alcohols present in other materials.

Many of these products are supplied in a concentrated liquid presentation which is diluted in water to produce a working solution, which should be changed daily or when it has become visibly contaminated.

ALMINAX RITE BITE

Philip Cooke, Purton Dental Practice, explains why Alminax Rite Bite is his bite registration material of choice

 

Despite the millions of pounds spent every year by dental manufacturers researching and developing, marketing and selling the latest developments in high quality impression materials, luting cements, crown and bridge materials, and technology – everything promising the most accurate fit and optimised aesthetics for the final crown and bridge restorations – bite registration remains one of the most important yet frequently neglected stages in crown and bridge work.

Providing your Technician with a correct and reliable bite registration is therefore one of the most time and cost saving factors in crown and bridge work.

There are lots of different options available to Practices looking for a reliable bite registration material, including various polyvinylsiloxane materials which deliver very dimensionally stable registrations but can be quite expensive. However there is not really any need to incur this cost because there are more cost effective but equally reliable wax based bite registration materials also available, including Kemdent’s Alminax range.

 

What makes Alminax the perfect wax bite registration material

To deliver a reliable and dimensionally stable wax bite registration you need a material specifically designed for the purpose. Simply warming up a piece of modelling wax, bending it into a horseshoe shape and asking the patient to bite down on it will not do.

To create an accurate and reliable wax bite registration requires a wax that enables the heat to spread uniformly throughout its volume, producing a consistency of softness so that the wax bite deforms evenly when placed within the mouth and it is bitten into. Generally materials used for bite registrations need to be stiffened or supported. If whole sheets of wax or sheets supported with metal plates are used the patients tongue can be disturbed leading to inaccurate registrations.

Investigations have shown that Alminax wax is the superior wax because it can absorb heat and soften quickly, it cools very easily and is very stable afterwards. Therefore it is the most suitable wax for bite indexes.

Alminax incorporates a conductive filler so that when it is warmed in the water bath, the heat is evenly spread throughout the thickness of the wax. Unlike conventional modelling wax which can have soft and firm parts, and does not necessarily deform evenly when it is bitten into.

Another advantage of Alminax bite registration wax is that is it thicker than normal modelling wax so it does not need to be folded in order to create a wax bite of adequate thickness. This folding frequently results in air bubbles becoming incorporated within the modelling wax bite. These air bubbles can expand and contract depending upon the temperature of the wax, resulting in distortion. What is more, if the patient happens to bite through an air bubble this results in loss of information at the contact points.

In addition, Alminax’s setting profile means that it remains robust ( stable and firm ) when removed from the mouth. This means it is harder than conventional modelling wax so it does not distort, leading to errors after it has been removed. Furthermore, it is more stable at a higher room temperature, for example within a hot Dental Laboratory, than normal modelling wax which means it is even less likely to become distorted.

Alminax bite registration wax is available in three presentations – sheets, Wax Full Arch and Rite Bite.

Alminax Wax Full Arch and Rite Bite are supplied in preformed U-shapes which mean that they do not need to be bent into shape, saving time. Compared with the simple sheet presentation, another advantage of these preshaped Alminax Wax Full Arch and Rite Bite options is that they feature a special cut away shape that allows adequate space for the tongue. Consequently there is no interference when the patient bites together, allowing the patient to bite comfortably in the correct position. The thickness of the Full Arch and Rite Bite wafers have been carefully selected too, so that they do not interfere with the soft tissues when recording the bite registration of a “normal” bite. Consequently they ensure that the plaster models do not hang on the wax when the models are articulated.

However I prefer the Rite Bite because it also incorporates a metal strip for enhanced accuracy and reliability.

Whichever option is chosen the manufacturers recommend that the wax bite is chilled in the mouth before removal in order to further reduce the risk of any hidden distortion. It should then be disinfected using an appropriate CE Marked Disinfectant ( for example Kemdent’s Practice Safe Soak ) before it is sent to the Laboratory.

 

Hints and Tips for success

Alminax Rite Bite wax wafers should be placed in a warm ( 55°C ) temperature controlled water bath for about 30 to 60 seconds so that they become uniformly softened throughout.

When prepared teeth are present a thicker layer of wax is required. Take an appropriately sized piece of one of the unstiffened wax wafers, supplied in the pack, and soften it in the water bath with the main index. Press the two pieces together and melt the edges together with a hot wax knife. Having different thicknesses of wax on the same bite registration does not matter because when it is reheated in the water bath it will have a uniform softness throughout. This is the most important part of a bite registration because it gives the patient the possibility to bite evenly and easily into the bite wax. If wax is just heated in a flame it does not soften uniformly and causes the registration to be inaccurate, like trying to chew a toffee in an up and down motion. The lower jaw will automatically move to the working side for the harder part.

When taking a registration adjust the warm index for length and width in the mouth. Alminax Rite Bite trims easily with scissors even through the reinforcement. Never adjust a cool index.

Replace the index in the controlled warm water bath to soften it evenly before placing it on the teeth in the largest arch in the mouth, normally the maxillary arch. Place the Alminax Rite Bite so that the outer edge follows the buccal line of the teeth. Try and keep it a little inside the outer cusp line because the wax will spread a little when the registration is made. If there is an overbite press the wax in the anterior region against the upper teeth with your finger to get a referring impression in this area as well.

Cool the index, but not too much, because now we come to the most crucial part. Take out the index and turn it over so that the smaller jaw side is visible. Cut the index along the line of the buccal cusps. If you see or suspect wax has gone up and pressed against soft tissues that wax must be cut away with a knife or scissors too.

It is always advisable to cut away wax distal to the last molar because soft tissue often goes up and onto this tooth and is compressed and distorted by the wax, possibly enough to disturb the registration when the models are mounted on the index prior to articulation.

Replace the index in the mouth and check the registration is perfect. If an index is completely cold and hard warm it up just a little in the warm water bath first. Once checked cool the index.

Remove index from mouth and pack it in a padded box for safe transport to the Laboratory.

 

Conclusion

Alminax Rite Bite is easy to handle, time saving and extremely accurate. It gives correct and reliable registrations virtually every time.

Both Dentists and Technicians find it easy to use and Technicians who’s Dentists use Alminax Rite Bite have no problems with adjustments or corrections.

Once you’ve tried it you won’t want to be without it.

DIAMONDS ARE A DENTISTS BEST FRIEND

Some existing users explain why Kemdent’s Diamond Carve is the ideal alternative to amalgam…

 

The continued use of mercury-rich dental amalgam has been controversial for decades, but now the globally binding treaty on the use of mercury, which was signed in Japan in October 2013, has, ultimately, signed its death knell. Whilst this won’t happen overnight, it means dentists will all need to find a suitable alternative. There are many to choose from, all with their own relative merits, but many believe that Kemdent’s Diamond Carve offers an extremely user-friendly and cost-effective option worthy of serious consideration.

Kemdent first introduced the Diamond glass ionomer cement (GIC ) range to the dental market in March 1999. Now,15 years later, the Diamond range is one of the world’s leading GIC’s used daily by thousands of dentists in more than a dozen countries worldwide.

Diamond provides dentists with a clinically proven GIC restorative material that effectively performs highly aesthetic restorative procedures, replacing traditional composite, glass ionomer and amalgam methods of working. Chemical curing, without dimensional change, means Diamond restorations can be placed in one increment, saving time and avoiding the creation of stresses within the restoration that can be caused by incremental build-up using composites. Both of these advantages also contribute to its relative lack of post-operative sensitivity compared with bonded composites. Fluoride release is another significant advantage.

Diamond is also far less susceptible to moisture around the operating site, partly due to its rapid chemical snap-set and its healthier, mercury-free composition. It quite categorically adheres to both enamel and dentine, without the need for acid etching – saving time and additional expense. Finally, there is no polymerisation shrinkage and consequent cracking associated with Diamond.

The Diamond range allows dental practices to perform various styles of chairside treatment. The firm consistency of the Diamond GIC range allows easy placement of the materials and rapid “snap-setting”, matching tooth colour in just over two minutes at normal room temperature. Gone are the days of sending away patients with poorly aesthetic, opaque, moisture sensitive restorations, with instructions to return a week later for polishing, hoping that when they return, the restoration would not have a crazed appearance and have been weakened by moisture contamination. There are various options available, including Diamond Carve and Diamond Rapid Set capsules.

 

Diamond Carve

Diamond-CarveDiamond Carve is a hand-mixed glass ionomer cement for posterior indications, including non-load bearing class I and II restorations, together with class V abrasion cavities. It can also be used for restorations in deciduous teeth, core build-ups, amalgam repairs – where it helps minimise the health risks associated with the removal of old amalgam restorations, and the cementation of posts in root canal restorations.

Diamond Carve Powder is made from alumina-silicate glass, containing calcium fluoride as well as strontium and barium for radiopacity, plus a number of dry acids to enhance the setting reaction. Diamond Carve Liquid is a water-based acidic solution. They are combined together in a 4:1 ratio, with one scoop of powder to one drop of liquid. Setting occurs through an acid/base reaction. Diamond Carve is self-adhesive to both enamel and dentine.

Available in one aesthetic shade, an immediate advantage over “dirty old amalgam”, it is manufactured from a special GIC which contributes to a range of features, including versatility and strength – with a 350MPa compressive strength, Diamond Carve is up to 50 per cent stronger than other glass ionomer cements; saliva resistance; excellent finishing; and wear resistance properties. In addition to this, tests have proven that there is no dimension change during the setting reaction and no post-operative sensitivity. These advantages, together with its packable consistency, durability and ease of use, make it the ideal aesthetic alternative to amalgam.

 

Hints and tips for using Carve

Diamondsbestfriend1Diamond Carve has a working time of two minutes-two minutes and 30 seconds, and a setting time of three minutes and 40 seconds-four minutes. It requires minimal preparation, simply the requirement to remove soft caries and undermined enamel, and no varnishing afterwards. It adheres to dentine and enamel without the need for any preparation of the tooth surface or a bonding system, thereby saving valuable surgery time and additional expense compared with composite materials. Carvable, it offers a “waterproof” chemical snap-set.

 

The procedure is as follows:

Step 1 – select the appropriate shade. When placed, the fresh cement is opaque. Translucency develops over the first couple of weeks.

Step 2 – remove caries and prepare the cavity with minimal tooth reduction

Step 3 – clean the cavity with water and gently dry. Remove smear layer by applying Kemdent Diamond Carve liquid for 15 seconds using a cotton pellet. Wash and gently dry.

Step 4 – place a vaselined matrix band, if required.

Step 5 – shake the bottle of powder to fluff the powder. Dispense the powder and liquid onto either one of the mixing sheets provided, or a glass slab at room temperature in the proportion of one scoop of powder to one drop of liquid. Do not compress the powder.

Diamondsbestfriend2Squeeze the liquid bottle gently to clear the opening, then hold the bottle vertically to avoid air bubbles and dispense one drop. For larger cavities, use multiple quantities of powder and liquid in the same 1:1 ratio.

Using a plastic spatula, mix half of the powder with the liquid to form a smooth, creamy paste. Then, mix in as much of the remaining powder as possible to form a firm, putty-like consistency. Do not make it dry or crumbly. In the case of multiple scoops of powder, incorporate each, in turn, into the liquid, making sure the final cement has a smooth and firm consistency.

It should take approximately 30-40 seconds to mix them together. Due to Diamond Carve’s snap-set and to achieve good adhesion to the enamel and dentine, always mix fresh material for each cavity.

After dispensing, the assistant should replace the caps tightly and start to clean the instruments and mixing slab before the material has set.

Step 6 – place the mixed material into the cavity and pack into place using conventional packing instruments. Diamond Carve has a firm, putty-like consistency, which makes it easy to pack. Once placed, carve as desired. The working time from start of mixing is approximately two minutes and 15 seconds. Diamond Carve has a snap-set after three minutes and 40 seconds, which quickly makes the restoration water resistant.

Step 7 – six minutes after start of mixing, excess material can be removed using either fine diamond finishing burs or diamond impregnated rubber cups, irrigated and water cooled.

Diamondsbestfriend3Step 8 – as a precaution, instruct the patient not to bite on the restoration for about one hour.

 

 

 

Customer feedback

Dr Martin Harris, of West Earlham Dental Health Practice, Norwich, said,

“I mainly use Diamond Carve for deciduous fillings, core build-ups, some interproximal restorations and as a fissure sealant. I like it because it is strong, quick and easy to use, reasonably aesthetic and caries inhibiting. I prefer to use it instead of amalgam in some circumstances because it bonds to the tooth and is good for open shallow cavities.”

Dr John Rees, from Rees Dental Practice, Birmingham, commented, “I use Diamond Carve because it is easy to mix and you can mix the exact quantity you require. There is no waste. I also like the way it bonds well to the tooth and is a lot harder than other glass ionomers, therefore, it lasts longer.
“I use Diamond Carve to restore primary teeth and class Vs in adults, where the restoration is held in place and shaped using a metal cervical foil, which gives a very smooth finish after the initial snap-set.”

Dr C P Taylor runs a mainly private practice in Wrexham and understands that time spent on good restorative techniques is the key to ensuring profitable success, as well as a satisfied patient. He said

“I first started using Diamond 90 in 1999 because I quickly recognised how it could help me cut down on treatment time and successfully provide more aesthetic results for my patients. However, I now use Diamond Carve as my preferred choice of restorative material.
Prior to using Diamond, restorations were often time-consuming and work intensive. They could take up to 40 minutes in total for a large cavity. By using Diamond Carve, I have reduced this time dramatically”.

“I use it primarily for class I and class II restorations, class V abrasion cavities, restoration of deciduous teeth and core build-ups. I’ve also used it to repair amalgams and to cement posts in root canals. I feel confident in using it for all of these indications because of its flexibility and versatility. When mixed together, the powder and liquid form a packable consistency that is almost like bread dough (flexible enough to roll, firm enough to pack). It doesn’t require light curing – saving loads of time – and, once set, it is rock hard and completely waterproof. It is then easy to finish and has excellent wear resistance. The final result is very aesthetically pleasing”

“Finally, thanks to its special composition, I no longer need to worry about dimensional changes within the restoration or post-operative sensitivity.”
Dr S R Sparks added, “My favourite use is in the domiciliary situation, where conditions are far from ideal. The patients are usually elderly with a lot of exposed dentine and glass ionomer is the only safe filling material. Diamond Carve is particularly useful as it can be used in both anterior and posterior teeth, giving an aesthetic and long-lasting restoration. It withstands loading well, without excessive wear or fracture, which is particularly important in posterior regions.”

Diamond Carve is part of the Diamond GIC range is one of the few dental restorative materials manufactured by Kemdent in the UK and an export success. For further information contact Kemdent on 01793 770090 or CLICK HERE
