A simple method to debond a cement-retained implant-supported fixed partial denture from its abutment screw connection: a case report

Abstract

Abstract Background Screw loosening of a cement-retained, implant-supported fixed partial denture causes the abutment and restoration to be completely separated as one unit from the implant body. In such circumstances, drilling of an access hole through the restoration is made to retrieve the abutment screw connection, and a new restoration is then fabricated. Method This clinical case presents a patient whose implant-supported fixed partial denture was completely detached from the implants, and it was retrieved from the abutment’s screw connection using acetic acid (vinegar). Results The cement was dissolved and the fixed partial denture was easily separated from the abutment screw connections thus avoiding damage of the restoration. Conclusion A new and simple technique was described to retrieve the FPD restoration from the abutments’ screw connections using undiluted acetic acid (vinegar).
