DenMat’s Perfectemp®10

DenMat’s Perfectemp®10 provisional material

Provisional restorations are a key part of everyday den tistry and their importance cannot be underestimated. Every definitive restoration begins with a successful provisional that plays a key role for an optimal restorative outcome. A well-fabricated temporary restoration provides a variety of functions:
1. Comfort and pulpal protection
 2. Preserves periodontal health
 3. Prevents movement of teeth
4. Provides esthetics
5. Serves as a diagnostic tool
The majority of practitioners still use lab-fabricated restorations, even if they are taking digital impressions. It’s important to create a temporary that will preserve the optimal bio logic and esthetic conditions to make the entire process as least disruptive as possible. There is nothing more frustrating than having food impaction, gingival bleeding, sensitivity or bad esthetics while waiting for that final crown. Just as important is making sure that the temporary stays in place and doesn’t break easily under light to moderate function. In addition, dentists are seeking simplicity, convenience, reliability and cost effectiveness.

Handling is Key
There are many ways that temporaries are fabricated, and in many instances an assistant is creating them. For that reason, it is important to have a material that is easy to handle and repeatedly shows consistent properties. The material should be easy to manipulate, trim and polish. A variety of templates may be used to fabricate a temporary-alginate, vacuum form template, PVS putty matrix-and the material shouldn't stick or fall apart when using them. The provider should be able to easily trim and adjust the material in the minimum time possible with the least number of steps.
Perfectemp10 handles extremely well with any matrix system. It displays minimal to no stickiness and may be trimmed and adjusted easily. The handling is improved due to a reduced oxygen inhibited layer and clean-up is simple compated to other temporary materials. Its low shrinkage allows for a well-adapted temporary and reduces remakes and sensitivity due to open margins.
The set time should be sufficient to allow for multiple units without changing your protocols from one procedure to the next. Of course, strength is important as sometimes provisionals are left in place for extended periods when serving as a diagnostic tool for more complex treatments. The last thing one needs is to inconvenience a patient and disrupt your schedule by constantly having to remake your temporaries.

Strength and Esthetics

Perfectemp10 comes in five convenient shades to provide a sufficient range for most situations that present. The small filler particle size allows for a shiny surface with minimal polishing. Its compressive and flexural strength are high enough to allow for multiple units to be made with reasonable function during the provisional phase. These are the reasons why Perfectemp10 excels at creating esthetic functional temporaries. Overall, the evaluators rated this material a premium product to use in their practices.

The Evaluation
Approximately 30 Catapult dentists took part in the evaluation of Perfectemp10. Features that were of most concern to the group were handling, set time, strength, and esthetics. Handling was rated as good to excellent, while 100% rated the material easy to clean. The set time was found to be what the manufacturer stated and provided sufficient time to create multiple units without being overly rushed. A large 77% of the group rated the product to have superior esthetics to what they use currently and none found them below. Despite the product category being quite saturated already, over 60% rated Perfectemp10 better than their current material and 47% indicated they would switch over.

Clinical Case
A patient presented with two heavily restored teeth
that could benefit from full coverage restorations, one with an amalgam and the other with a composite filling (Fig. 1). The patient had a number of large restorations crowned over the years as the teeth fractured and she wanted to be proactive and not risk further breakdown over time. The teeth were prepared (Fig. 2) and the temporaries where made using a PVS template made prior to treatment (Fig. 3). After initial setting in the mouth, the material was removed and trimmed (Fig. 4) in the template as it completes setting. After any neces-
sary adjustment, the provisionals were cemented using a temporary cement (Fig. 5). The final temporaries in place (Fig. 6).

Conclusion
Temporaries play are large role in everyday practice and a predictable and simple protocol is important for success. Having a material you can rely on to deliver consistent, quality results is equally important. Perfectemp10 is just that material. It’s easy to handle, highly esthetic and has the toughness to be used for multiple units. Our evaluators certainly recommend Perfectemp10 for youreveryday temporization needs.
