Abstract: A dental prosthesis apparatus with reference points for overlapping of multiple images to form a composite image, in which a pair of implant assemblies each attaches to a clip assembly having first and second opposing rail clips secured together with a fastener while holding a portion of an elongated rail that extends between the implant assemblies, and the rail defines a differentiation characteristic for use as reference points for matching of a plurality of images in overlapping relation for forming a composite image. A method of providing a dental prosthesis with reference points for imaging is disclosed.

Abstract: A dental prosthesis apparatus, comprising at least a pair of implants for selective imbedding in maxillary bone structure and each having an angle-adjusting abutments to which a rail clip assembly attaches, each rail clip assembly holding a portion of a rail between a lower rail clip and an upper rail clip, the rail and clip assemblies connected together, for seating of a denture to the abutments. A method of fabricating a dental prosthesis is disclosed.
