<p>Prosthetic apparatus for promoting and supporting guided bone tissue regeneration in at least missing or excised portions of the human mandible or maxilla and in bony defects of the mandible and maxilla. The apparatus includes a bone attachment tray formed of tissue-biocompatible titanium sheet material having perforation therethrough for receiving bone screws to affix the tray to stump portions and ridge sections of the mandible or maxilla proximate the missing or excised stump portions or ridge sections and one or more tissue-biocompatible metallic dental tooth root replacement implants which are releasably affixed at one end to the inner surface of the tray and which depend from the tray into the missing or excised portions or bone defects of the mandible or maxilla for incorporation and support in bone tissue regenerated within the tray. The inner surface of the attachment tray may have affixed thereto one or more layers of a biologically and chemically inert microporous membrane sheet material to promote the guided tissue regeneration of replacement bone within the tray and protect the space thereunder from the entry of unwanted bacteria and competitive tissues during the healing and bone regeneration period.</p> |
