Abstract: A thermoplastic, one-piece coping insert adapted for use with a dental implant anchoring means includes a shaft that fits into an opening in a dental implant, an abutment head joined to the shaft and adapted to conform to, and fit smoothly on, or in the top surface of the dental implant, a bendable restriction or groove to facilitate preferential bending of the insert at the restriction when the insert is heated to the softening temperature of a thermoplastic, and a relatively unbendable post atop the restriction for receiving and supporting a dental prosthesis such as one or more prosthetic teeth.
