In recent years, dental microscopes are widely used in endodontic and periodontal fields. However, their application is not so common in the field of prosthodontics yet. The superstructure of implants may be damaged or detached by occlusal changes caused by aging, bruxism, an ill-fitting superstructure, overloading, and malfunction. This damage might sometimes lead to implant fractures, damaged abutments, abutment screw fractures and gold-alloy screw fractures. We report a technique for removal of broken segments without damaging the implant using an ultrasonic tip under microscopic vision.
