This clinical case utilizes the Clear Custom Matrix Technique to place a large light-cured Class IIi composite restoration in a maxillary canine. This clinical case was part of a continuing education lecture presented and video taped at Loma Linda University School of Dentistry. It is recommended that you watch my Maxillary 1st Molar (#3) MO Light-Cured Composite video first on YouTube since it gives more detail about the Clear Custom Matrix Technique. If you know the technique yo will better understand how you can save 5 to 10 minutes of chair-time on each composite you place.
