Abstract: A matrix ring includes a biasing ring and a pair of opposing tines. The biasing ring includes a substantially hoop-like configuration terminating at two opposing ends. The pair of opposing tines extend inwardly from each of the two ends of the biasing ring toward each other. Each of the pair of opposing tines is coupled to the respective opposing end about a central region thereof and extends radially outwardly therefrom. Each tine includes a flame body having a central ridge and opposing lower extensions, the lower extensions terminating at an exposed face. The portion of the lower extensions proximate the exposed face being able to move relative to the rest of the flame body so as to better position on the teeth of a patient. A superimposed pad over portions of the flame body provides a deformable surface for engagement with the surface of the tooth of a patient.

Abstract: A matrix ring comprising includes a biasing ring and a pair of opposing tines. The biasing ring includes a substantially hoop-like configuration terminating at two opposing ends. The pair of opposing tines extend inwardly from each of the two ends of the biasing ring toward each other. Each of the pair of opposing tines is coupled to the respective opposing end about a central region thereof and extends radially outwardly therefrom. Each tine includes a frame body having a central ridge and opposing lower extensions, the lower extensions terminating at an exposed face. The portion of the lower extensions proximate the exposed face being able to move relative to the rest of the frame body so as to better position on the teeth of a patient. A superimposed pad over portions of the frame body provides a deformable surface for engagement with the surface of the tooth of a patient. In the Specification The opposing tines 14a, 14b are shown in FIG. 1.

Abstract: A matrix ring comprising a ring body and a pair of opposing tips mounted to the ends of the ring body. Each of the tips may be movably coupled to the ring body about an axis of rotation. Optionally, or alternatively, the tips may be removably mounted to the ring body. For example, the ring body may include a pair of opposed spaced apart ends each with a tine mounted at each end. Further, at least a portion of the matrix ring may be formed from a bulk amorphous alloy.
