Removal of Fractured Dental Implant Screw Using a New Technique: A Case Report
Implant restorations can fail biologically or mechanically. Biological factors include unsuccessful osseointegration or presence of peri-implantitis. Mechanical failures include crown fracture, framework fracture, screw loosening, and screw fracture. Fracture of the implant abutment can be a serious problem as the fragment remaining inside the implant may prevent the implant from functioning efficiently. The procedure used for removal of the fractured screw portion is described in this clinical report.
