A dental contact matrix system .[.is described for the placement of dental fillings. The dental contact matrix system.]. includes a matrix, a retainer for placing and retaining the .[.5.]. matrix and an elastic wedge. The retainer includes two lugs or tines that fit between two teeth on the buccal and lingual sides of the teeth. The lugs are connected by .Iadd.a .Iaddend.spring member that presses the lugs against the lingual and buccal sides of the teeth. There is an adaptation to hold the elastic wedge in a stretched condition between the lugs.

Methods and devices for interproximal dental restoration are disclosed. One version of the present disclosure provides a method for the restoration of a tooth including a top surface, and an interproximal surface facing an adjacent tooth. The method of restoration includes removing a portion of the top surface of the tooth, and a portion of the interproximal surface of the tooth to form a hollow cavity preparation extending from the top surface to the interproximal surface. The removed portion of the interproximal space is surrounded by a dental matrix. Restoration of the tooth further includes moving the dental matrix away from the hollow cavity preparation towards the adjacent tooth, and bonding at least a section of the dental matrix to the tooth. Light-curable composite resin is then injected into the cavity preparation and light cured.

A wedge system for use in a dental restoration procedure for a posterior tooth. The wedge system includes a first wedge including a body portion adapted to be disposed in an approximal space, a first arm extending from the body, a second arm extending from the body portion, a gap formed between the first arm and the second arm, a first rib arranged on an inner surface of the first arm, and a second rib arranged on an inner surface of the second arm, wherein each of the first and second ribs is adapted to engage tissue defining the approximal space. In some cases, the wedge system may also include a second wedge including a body portion, at least a portion of which can be disposed in the gap of the first wedge to removably secure the second wedge to the first wedge.

A disposable, self-inflatable, matrix (tooth dam) used to form a temporary, removeable side wall for the placement of a tooth filling material. It has an array of three concavities (distal, central and proximal) formed in a polymer wrap that has a planar substrate sheet affixed across the front face of the wrap. The distal air chamber has a volume that equals or exceeds the combined volume of the central and proximal air chambers. Directly below the distal concavity on the inner face of the planar substrate is an adhesive region. When the distal air chamber is depressed, the air within inflates the other air chambers and it is retained in its compressed state by the adhesive region. The remaining air chambers press against one tooth and exert enough force to elastically secure the planar panel around the adjacent tooth. It prevents the tooth filling material from leaving the prepared tooth and entering the space between.

A disposable, inflatable, matrix (tooth dam) used to form a temporary, removeable side wall for the placement of a tooth filling material. It establishes the original dental anatomy of the tooth, and maintains the correct contact between adjacent teeth for flossing purposes and gingival health. It accomplishes this by inflating a pair of self-sealing air chambers that extend from the back face of a planar panel that they are formed on, such that these chambers contact and press against the adjacent tooth and exert enough force to elastically secure the planar panel without wedges and clamps. It prevents the tooth filling material from leaving the prepared tooth and entering the space between the teeth to enhance flossing and proper dental hygiene. This device will greatly enhance patient comfort, procedural efficiency and consistency
