Abstract
An overdenture bar assembly is shown having first and second root members each mounting a bar attachment abutment. Each bar attachment abutment has a post formed with a locking taper receivable in a matching tapered bore in the repective root member and a transversely extending bore in a head portion which receives an end of a cylindrical bar. A jig member is shown formed of a flat plate having a central reference bore between two outer bores and an annular insert is closely receivable in each outer bore. The outer bores serve to guide a drill bit to provide parallelism and the top surface of the plate cooperates with a mark on a drill bit to provide a reference for measuring the depth of the bore being formed.
