Abstract
A method is described for fabricating a dental prosthodontic restoration to be fitted on at least first and second implant fixtures, each of the implant fixtures supporting an abutment. The method begins by fitting a first abutment screw assembly to said first implant fixture, the first abutment screw assembly including a screw portion, and an attachment secured to the screw portion. The first abutment screw assembly is then tightened to retain the assembly in the first implant fixture. Then, the method continues by fitting a screw portion of a second abutment screw assembly to said second implant fixture and tightening the screw portion to the second implant fixture. Using an intra-oral jig mechanism, the attachment of the second abutment screw assembly is then located in a predetermined position relative to the screw portion thereof such that the attachments of the first and second abutment screw assemblies have a parallel orientation. The method can alternatively be practiced using two-piece assemblies.
