Case report: prosthodontic treatment for the transmandibular implant

The Transmandibular Implant is a transosteal implant developed to help improve masticatory function in patients with severe mandibular atrophy. It is a functional implant with a rigid box frame design which allows acceptance of masticatory loads in mandibles with minimal bone height. The implant is fabricated of a gold alloy and is placed between the mental foramina from a submental approach. The prosthesis is fabricated as an overdenture and retention is obtained by means of retention sleeves adapted to Dolder bar segments of the superstructure. Denture comfort and function can be greatly improved for patients with severely resorbed mandibles.
