A 65-year-old male patient reported to the Department of Prosthodontics, with the chief complaint of fractured mandibular implant supported over denture due to which he was unable to wear his denture since one week. Patient was systemically healthy with no medical compromise. History revealed placement of two endosseous dental implants with ball attachments [Table/ Fig-2] three years back and history of previous denture fracture one year back and new denture made, subsequently fracture of second set of denture occurred within the gap of six months. Intra oral examination revealed natural teeth in relation to 15,17,23,24,25. The radiographic investigation revealed well osseointegrated implants in relation to the lower arch. The main treatment objective was to overcome this repeated fracture of the lower denture. So it was planned to reinforce mandibular implant supported over denture with metal. As the patient is socially active, the fracture denture was temporarily repaired and given to the patient in order to provide minimum function. PROCEDUREAlginate impression of edentulous ridge along with the ball abutments were made with perforated edentulous tray and special tray fabricated with auto polymerizing acrylic resin. Border molding was done with the help of green stick compound and final impression was made with additional silicone. Metal housings were not removed from the existing denture as patient did not want to be edentulous. Definitive casts poured with type II dental stone. Relief wax was placed along the crest of the residual alveolar ridge and tissue stops were positioned. Since the metal housings were placed in the repaired denture, shaped block out was made over Dentistry SectionRemedy for Repeated Implant Retained Denture Fracture-A Challenging Case Report ABSTRACTThe most common site of fracture in a maxillary or a mandibular complete denture is along an anteroposterior line that coincides with the labial notch in in the denture which used to provide the frenum relief. Osseointegrated implants have been a boon to the patients who are completelly edentulous and are not satisfied with the conventional removable complete denture approach.Implant supported dentures have proven to provide superior retention and support for removable complete dentures. Nevertheless, fracture of the denture bases is a common complication of implant-supported mandibular overlay dentures,ecspecially when the artificial denture is opposing natural dentition. This article describes and illustrates a method of reinforcing implant-supported mandibular overdentures to overcome this problem. the ball abutments of the definitive cast with the similar dimensions [Table/ Fig-3]. Further, definitive cast was duplicated with agar. Refractory cast was achieved, on which wax pattern was adapted corresponding to the planned metallic frame work design [Table / Fig-4]. The pattern along with the refractory cast was invested, burned out, casted, divested, finished and polished.The framework was tried in patients mouth and was evaluated f...
