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 providing a wall to maintain a tooth’s structure and shape during restorative procedures, such as cavity fillings. During typical filling procedures, particularly filling cavities on interproximal surfaces, dentists must fill one tooth at a time since matrix bands cannot be placed adjacent to one another, as the thickness of two bands exceeds the tooth contact diameter between the teeth. The resulting process of placing matrix bands for both teeth is cumbersome and time inefficient. A new dental matrix band design is desired to alleviate the need to repeatedly place bands. The device should employ a dual-band system that is thin enough to securely and comfortably fit between the affected teeth and is able to simultaneously mold 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.
