Abstract
Various types of removal kits have been offered by several companies to address implant prosthetic complications, but complications are not easy to resolve. In particular, the fracture of the internal tapered abutment is difficult to remove with conventional tools if the abutment and the seal inside the fixture are rigid. This clinical report reported a case of abutment fracture in internal taper connection type fixture. A 63-year-old male patient presented with a broken implant restoration that was connected into an internal taper type implant. To retrieve the remnant of the broken abutment in the fixture, multiple instruments were applied to break conical seal. The broken abutment was barely removed with rotary diamond instrument, damaging the internal taper connection area of the fixture. Though there was no cold welding was reported, conical tight seal generated by applied preload make difficult to removal abutment without screw.
