Approximating surface matrix band for dentist to use for patients

Creation of a dental matrix band that effectively partitions adjacent teeth for more efficient tooth restoration procedures on interproximal cavities

Project Overview

Matrix bands are a commonly used dental tool which assist dentists by creating an outside contour of a decayed tooth. They provide support, shape and contour for replacement filling material while protecting surrounding tissues. During typical filling procedures for cavities on interproximal surfaces, or two adjacent teeth, dentists must fill each tooth separately. This is a tedious procedure as each matrix band must be prepared for each tooth, which includes shaping, placement and securing with dental wedges and rings. These must be done one after another because two matrix bands cannot fit in the interproximal space as together they are too wide and would create gaps in the restoration. A new dental matrix band design is desired to alleviate the need to repeatedly place bands. The device should employ a dual-band system with a thickness less than or equivalent to current matrix bands throughout such that the fit is secure and the band molds to the appropriate convex/concave contour of each tooth. The finalized product should also maintain the tensile strength, malleability, and space efficiency of current matrix bands. The material used to fabricate the matrix band must not cause any irritation, must be biocompatible, and must be non-reactive to filling materials.
