See how to use the OVC Wedges for deep margin elevation prior to placement of the McDonald Matrix Band. 

The OVC Wedges are anatomically shaped to follow the natural curve of the tooth. They come in both a left and right version for mesial or distal placement, and are an ideal tool for deep margin elevation (DME).



Case One

01-Pre-300x194 02-Wedges-300x194 03-Etch-300x194
A. Prep tooth. B. Insert OVC Wedges. C. Etch and bond.

D. Complete the deep margin elevation using composite. E. Remove OVC Wedges. F. Place McDonald Matrix Band and complete OVC procedure as normal. 


 Case Two
