ABSTRACT:
A module useful for forming a foundation for a dental prosthesis, the module including at least one each of (a) a post and (b) an extension unit, the post having a threaded end adapted to anchor the post into rigid dental materials such as tooth stubs or bone matrix, and a second retaining end for engaging the extension unit. The extension unit comprises an engaging end to engage the retaining end of the post, and one or two leaves extending from the engaging end transversely from the post. The engaging end is so sized and shaped as to maintain a sloppy fit with the retaining end of the post. The sloppy fit permits a minor, constrained degree of rotation of the extension unit with respect to the post. At least two such modules can be used to form the foundation for a rigid prosthetic dental bridge; at least one of the extending leaves on each module is so formed as to be capable of coupling with one of the extending leaves on a second such module. A pair of coupled such modules forms a prosthetic foundation in the mouth.
