Often when I lecture on composite dentistry I get asked about improving the final surface texture, polish and sculptability when doing anterior teeth. In a previous blog I looked at the categories of composites and understanding their physical and handling properties based on composition. Microfill composites are an older material formulation that is still on the market for precisely the reason of it’s esthetic qualities. These materials have a lower filler percentage which means there are compromises in the areas of material strength, wear and durability under load. However, microfills to date still have the highest polishability of any composites. Not only are the easy and beautiful to polish in your office, but they maintain that polish over time due to normal hygiene with a toothbrush.
Understanding the properties of microfills, there perfect use is as the final surface layer in an anterior composite. So for anterior composite veneers, class four composite repairs or class three composites that come through to the facial using a.5mm facial enamel layer of a microfill may be the solution you are after. The material will hold up and do well in this application as it is not under load. Many of the manufacturers have microfill products available for example Durafill (Heraeus), Heliomolar (Ivoclar Vivadent) and Renamel (Cosmedent).
