The ArcusDigma is an instrument based functional diagnosic device is used to detect Temporomadibular Joint (TMJ) functional movement. The TMJ or the jaw joint is a very special joint as it allows for complicated jaw movements during eating and speaking. An accurate record of TMJ functional movement must therefore be replicated when fabricating dentures or multiple restorations. By using the ArcusDigma device, we can create restorations that will be in harmony with the natural movements of one’s jaw joint/ TMJ. This reduces the risk of misaligned restorations and post-treatment pain.
