Case Report: Microbrush Stamp Technique by K. Varsha Rao



After spending a lot of chairside time adjusting, finishing and polishing posterior restorations, I came across a simple but effective way to restore posterior teeth with composite material. This is the microbrush stamp technique. The purpose is to replicate occlusal anatomy by making a copy of the original unprepared tooth structure.

The technique has evolved. For instance, I made a slight modification to the original technique by using a piece of cling film instead of Teflon in the protocol.

Here is a pictorial description of the entire procedure.























The advantage of the cling film over Teflon was that, unlike the original protocol that advises one to use Teflon as barrier material multiple times to sculpt with curing, I could place cling film and cure through it, thereby protecting the composite material from being exposed to ambient light multiple times.

I also used the original protocol advocated by Dr. Waseem Riaz whose videos on the procedure I had seen before I tried the same. Here’s a pictorial explanation of the procedure.

Conclusion
The microbrush stamp technique is an easy-to-follow procedure to recreate occlusal topography, but is restricted to teeth with intact occlusal anatomy.
