Abstract
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.

Total Claims: 17
Claim 1
Independent Claim
180 words
A method 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, comprising the steps of: (a) fitting a first abutment screw assembly to said first implant fixture, the first abutment screw assembly including a screw portion, and an attachment; (b) tightening the first abutment screw assembly to retain the first abutment screw assembly in the first implant fixture; (c) fitting a screw portion of a second abutment screw assembly to said second implant fixture, the second abutment screw assembly including an attachment that is attachable to the screw portion of the second abutment screw assembly and pivotally adjustable relative thereto; (d) tightening the screw portion of the second abutment screw assembly to retain the screw portion in the second implant fixture; and (e) using a jig mechanism to precisely locate the attachment of the second abutment screw assembly 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.

Claim 3
Dependent Claim
29 words
The method as described in claim 1 further including the step of: (f) securing the attachment of the second abutment screw in the predetermined position using a resin material.
Claim 4
Dependent Claim
33 words

Claim 5
Dependent Claim
49 words
The method as described in claim 3 further including the steps of: (h) burning away the resin material while the attachment is maintained against movement relative to the screw portion; (i) soldering the attachment to the screw portion; and (j) polishing and finishing the attachment and the screw portion.
Claim 6
Dependent Claim
38 words
