title: Piezoelectric Trapezoidal Osteotomy for the Retrieval of a Displaced Dental Implant in the Osteoporotic Mandibular Body.
abstract: A female patient in her mid-seventies was referred to our department for the removal of a displaced implant within the right posterior mandible. A trapezoidal window was made using a piezoelectric device. The implant was extracted, and the osteotomized window was replaced without fixation. Caution should be exercised during implant placement in patients with osteoporosis because of the risk of implant displacement. Displaced implants can be easily retrieved by piezoelectric trapezoidal osteotomy.
