Profile: Darway, Inc is a manufacturer of dental instruments. We offer matrix rings, composite instruments & accessories, matrices and retainers. Our Palodent Sectional Matrix System is designed to be used for the placement of posterior resin composite restorations. This system consists of one size of contoured sectional matrix bands and a BiTine ring. It provides both wedging and matrix contouring in a single system. The purpose of the BiTine ring is to apply an interproximal wedging force to enhance contact formation and to aid in the proximal contouring of the restoration. Our introductory kit contains four BiTine rings, sectional matrices, and a VHS instructional video.
