ABSTRACT:
The present invention relates to an endosteal implant system and a method for mounting a dental prosthesis on one or more implants. The system comprises an implant, a two-piece anchor whereby one piece is an angled support for mounting a dental prosthesis and the second piece is a threaded base portion for securing to the implant. The support is seated within the base portion and is rotatable about the longitudinal axis of the base portion. The alignment is achieved by first threading in the base portion into the implant and rotating the support until a best alignment is made. An accurate visual intra-oral evaluation of the anchor alignment is made utilizing a unique alignment handle which is snapped into each support. If the alignment is not satisfactory, the support with the alignment handle can be rotated until a satisfactory alignment is achieved. If a satisfactory alignment is not visually indicated, differently angled prosthetic supports may be used in various bases to achieve a satisfactory alignment of all supports. When a satisfactory alignment is achieved, the base and the support are marked to capture the aligned orientation. The base portion is removed from the implant and then the support is bonded to the base portion using the mark to correctly align the support in relation to the base portion. The anchor is again threaded into the implant. Because of the precise nature of the threading, the anchor will align as marked when completely threaded into the implant. The dental prosthesis can be then attached to the anchor.
