Abstract:
An engagement mechanism for a dental prosthesis, comprising:A) dental implant means having first and second ends, said first end being mounted to a user's bone and said second end having a first socket defining a cavity and an entrance and further including internal outer and inner stopper ridges mounted at a parallel and spaced apart relationship with respect to each other;B) an O-ring member cooperatively and snugly receivable within said outer and inner stopper ridges; andC) a post member having third and fourth ends, said third end being rigidly mounted to a prosthesis and said fourth end having a shank and a cooperative headed termination with a diameter larger than said shank and said headed termination being receivable within said cavity upon the application of a force of a predetermined magnitude to cause said headed termination to deform said O-ring member in passing there through said O-ring member being the sole support for said headed termination and shank and said second socket being cooperatively larger than said headed termination thereby securely lodging said headed termination in said cavity and said shank being surrounded by said O-ring member so that contact between said post member and said dental implant means is prevented.
