Repair of a fractured implant overdenture gold bar: A clinical and laboratory technique report

This clinical report explains a convenient, efficient, yet effective alternative for management of fractured substructure cast bars for implant-retained overdentures. The technique allows the fracture to be repaired at low cost and short time without remaking the substructure and the denture and further allowing the patient to keep their denture. The report sketches the clinical and laboratory procedures involved in the repair.

Key words:

Dolder bar - implant-supported overdenture - soldering
