Abstract
A force damping dental bridge assembly which damps compressive, tensile, and lateral forces on a prosthetic tooth and jawbone through use of synthetic periodontal ligament fibers in the form of a damping membrane. Multiple layers of arcuate components and Morse taper interconnections secure the assembly. A threaded implant that penetrates the jawbone defining a tapered, conical inner cavity which receives a shank protruding downwardly from a full bar. An arcuate damping membrane positions on the bar and a half-bar positions over the membrane; whereby the damping membrane is sufficiently resilient to enable lateral and axial movements by the prostheses affixed to the half-bar. A plurality of protuberances extend from an upper surface of the half-bar to enable sculpting and affixation of prostheses thereon; and whereby a plurality of fasteners detachably connect the prostheses to the bar and/or implants in a snap-fit relationship that can be detached with an implement adapted to unsnap the assembly from a patient's mouth.
