ABSTRACT:
A dental prosthesis foundation capable of being finished or adjusted or repaired and which may be assembled and adjusted to variable jaw ridge sizes, and formed with self-curing hardened resins. The foundation supports prosthetic teeth and is permanently but removably secured to the jaw by implants embedded in hard dental tissue, such as tooth stubs or bones. The dentures can be readily repaired or adjusted for changes in the jaw of the patient, by chairside techniques available to dentists. The foundation can also be adjusted to changes in size and shape of ridges in the jawbones for more comfortable use of the dentures secured on such prostheses, by utilizing spheroidal or ovoidal locking caps preferably initially formed of non-adherent polymers.
