ABSTRACT:
An oral chock exerts uniformly axial forces on dental prostheses to seat the prosthesis. The chock is preferably shaped like the dental arch, and wedge-shaped to align the surfaces of the chock with the occlusal surfaces of the teeth. The chock is large enough to receive the entire dental arch, so that one or a plurality of prostheses of any size or extent can be seated. The chock may be scored for separation into partial chocks, and the central posterior portion may be removed for palatal and lingual relief. The chock is formed of expanded plastic material having a frangible cellular structure for deformation of the chock so that the chock will exert uniformly distributed forces. Though deformable, the material has sufficient strength to seat the prostheses.
