Composites: Better, Faster and Easier

Abstract

Two hour continuing dental education lecture presented by James C. Hamilton, DDS at Loma Linda School of Dentistry with a live demonstration on a typodont of the Custom Matrix Technique for light cured dental restorative materials. This technique utilizes a clear poly vinyl siloxane bite registration material to take a small impression without a tray and uses that impression as a die to force the unset light cured dental restorative material into the original anatomy, surface texture and occlusion that the patient had when the procedure started. Then the restorative material is cured through the clear bite registration material creating a hard smooth surface without an air inhibited, layer reducing or eliminating any finishing or polishing, and saving 5 to 10 minutes of chairtime. If the original surface is defective that defect is easily filled in with red border molding wax prior to taking the impression with a clear bite registration material. The lecture utilizes the following cases to teach the technique: Porcelain Veneer Temporization, #9 Cervical Abrasion, #3 Mesial-Occlusal, #19 Mesial-Occlusal,#13 Mesial-Occlusal, #22 Rest for Partial Denture, #6 Large Class 3, Available Products, #18 Occlusal, #10 Class 5 (Penetrating Stain), #9 Class 5 (Gross Caries), #17 and 18 Occlusal, #4 Distal-Occlusal (Sectional Matrix), #12 Distal-Occlusal, #10 Peg Lateral,and #30 Occlusal (Marginal Breakdown). The Live demonstration restores a MO on #31 and eliminates simulated gross caries on a molar prior to taking a clear impression of a surface that will be transmitted to the new restorative material.
