A coping insert adapted for use with an endosseous dental implant anchoring element includes a shaft for insertion into an opening in the anchoring element and a head end for engaging and supporting a dental prosthesis. The insert is molded entirely of a resinous plastic and the head end and the shaft constitute separate elements joined by a ball and socket type joint for allowing angular positioning of the head end relative to the shaft. The ball and socket type joint include cooperating surfaces which can be bonded together when the head end has been positioned in a predetermined position relative to the shaft. The socket element portion also includes a pin element for allowing axial adjustment of the head element relative to the shaft element.
