title: Salvaging an angled implant abutment with damaged internal threads: a clinical report.
abstract: This clinical report describes a technique to fit an existing fixed detachable implant-supported prosthesis to a zygomatic implant abutment with stripped internal threads. The threads of the abutment were retapped and a wide diameter/wide head retaining screw was used to secure the existing prosthesis on the abutment. Care is needed in the retrieval of broken screws so as not to damage the internal threads of the implants, which might lead to irreversible complications.
