New instrumentation and technique for obtaining consistent interproximal contacts of direct Class II composite...

The difficulty in obtaining tight proximal contacts and properly placed contours in direct Class II composite resin restorations continues to demand a high level of proficiency when using conventional Class II techniques. Despite the highly improved composite resins and fourth-generation dentin bonding systems available, comparatively little advancement has taken place in instrumentation for reducing technique sensitivity and procedural time. This article introduces a prototype instrument which uses simple mechanical principles to overcome the difficulties in placing direct Class II composite restorations. The learning objective of this article is to familiarize the reader with the instrument, its principles, and the application technique.
