A novel technique for retrieval of cement-retained crown from an implant abutment and converting it into a combination prostheses

Abstract

Dental implant restoration is known to be a widely accepted treatment modality for the replacement of missing teeth and the restoration of masticatory function. Abutment screw loosening is one of the most common causes of failure in single implant-supported restorations, next to loss of osseointegration. Moreover, cement-retained implant-supported prostheses are infamous for their lack of predictable retrievability compared to screw-retained implant-supported prostheses. Management and retrieval of loosening screws are challenging, and this clinical report discusses the procedure for retrieving prosthesis from the abutment of the mandibular molar tooth with minimal damage to the existing restoration, making it possible to be reused.
