Özet
CASE DESCRIPTION: A 55-year-old male patient presented with the complaint that the implant-supported crown in the lower right first molar area had fallen off. Although the abutment screw was successfully removed, the cold-welded abutment could not be retrieved from the implant body using various techniques (using manual attempts, ultrasonics). The patient declined implant removal and consented to the proposed post-core treatment. Under water irrigation, the cold-welded abutment part and screw hole were meticulously abraded using an aerator and a tungsten carbide bur. An impression of the screw channel and the implant body surface facing the abutment was taken using additional silicone impression material and a standard tray. The working model was obtained using type 4 dental plaster. Dental porcelain was applied over the core. During the try-in, lateral excursive contacts were eliminated and centric relation contact was established. The restoration was finally cemented intraorally with glass ionomer cement. At the 21-month follow-up, the restoration remained intact with no signs of decementation or porcelain chipping. Radiographic evaluation revealed no peri-implant bone loss.
