Abstract
A method of damping compressive, tensile, and lateral compressive and tensile forces on one or more prosthetic teeth and an implant recessed into jawbone through use of synthetic periodontal ligament fibers in the form of a damping membrane within a dental bridge assembly. An arcuate damping membrane positions on a full 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.
