Publication number: 20190000595Abstract: A Morse taper dental implant providing two or more Morse taper interactions to secure a dental abutment within an implant and beneath a prosthesis. The implant (or anchor) penetrates the jawbone. The abutment having a conical male Morse taper component positions within a female socket forming part of a prosthesis. The abutment comprises an abutment platform from which a conical male Morse taper component extends for creating a second Morse taper interaction with a female socket. At least one aperture forms in the female socket to enable an implement to pass through for engaging the abutment, so as to release the Morse taper interaction(s).Type: ApplicationFiled: July 3, 2017Publication date: January 3, 2019Inventor: Paul Kenneth Clark, JR.

Publication number: 20190000596Abstract: 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.Type: ApplicationFiled: July 3, 2017Publication date: January 3, 2019Inventor: Paul Kenneth Clark, JR.

Publication number: 20190000600Abstract: A declogging assembly (20) is configured for use with a suction conduit (10). The suction conduit has a head (14) at a first end (15) and a vacuum tube connection (16) at a second end (17). The assembly includes a body (30). The body defines a first aperture (32), a second aperture (34), and a third aperture (36). The assembly also includes a plug (40) disposed within the body (30). The plug has a surface (42) configured to contact the head (14) of the suction conduit (10) so as to move the plug from a first position, in which the first aperture (32) is in fluid communication with the second aperture (34), to a second position, in which the first aperture (32) is in fluid communication with the third aperture (36). The assembly (20) also includes a biasing member (50) configured to bias the plug into the first position.Type: ApplicationFiled: August 17, 2016Publication date: January 3, 2019Applicant: MUSC FOUNDATION FOR RESEARCH DEVELOPMENTInventor: Stephen P.
