Abstract

A thin articulating film which is susceptible of folding, wrinkling, crimping and the like is held taut in a generally U-shaped frame to which the film is permanently affixed at a part of its periphery. The edge of the film spanning the ends of the arms of the frame is unframed. The frame can be integral with the film. Devices for full-arch, anterior-arch and quadrant occlusal adjustment, and for contact adjustment between two adjacent teeth in one arch or another where one tooth or both may be a restoration, are described.

1. 1. A tooth marking device comprising a thin articulating film as little as 15 microns thick which is susceptible of folding, crimping and wrinkling in the manner of paper and the like, and permanently affixed to a portion of the periphery of said film, frame means that is flexible and stiffer than said film, said frame means being generally U-shaped with a bight portion and first and second arm portions and said film substantially filling the area within said frame means, said film being free of said frame means only at its edge spanning the free ends of said arm portions, and being fastened continuously to said bight and arm portions at all other parts of its periphery, and said film being held taut against crimping, wrinkling and folding by said frame means said frame means being flexible so as to permit said film to conform with occlusal or contact surfaces of teeth being marked.
2. 11.11. A unitary article of manufacture comprising a tooth-marking dental articulating film as little as 15 microns thick with a frame continuously attached to only a major portion of its periphery, a minor portion of the periphery of said film being unframed, said frame being flexible and stiffer than the film for providing flexible peripheral support to the film and holding the film taut in the frame and at the unframed portion of said periphery, so as to permit said film to conform with occlusal or contact surfaces of teeth being marked.
