Introduction to the case
Examined one of my original Sonicfills. It was a 2 years old large MO composite on #31. Margins were excellent except for a small hard pit void on an occlusal margin. I don’t blame that on the SonicFill material, I can be guilty of such a thing with any composite material. This is conjecture, but I believe the downward forceful pressure of the stamp technique will reduce the occurrence of marginal defects.
