Oral and maxillofacial surgeryOnline only article: Case reportThe removal of a malpositioned implant in the anterior mandible using piezosurgery

In oral, cranio, and maxillofacial surgery, a close relationship among the bone, nerves, and blood vessels can be regularly observed. Surgical procedures for the removal of dental implants have the potential to cause vascular injury and bleeding in the floor of the mouth and internal anterior region of the mandible. Furthermore, conventional osteotomy techniques always require extensive protection of adjacent soft tissue because cutting is not limited to bone and could easily affect other tissues when applied improperly. We report the removal by means of piezosurgery of a malpositioned osseointegrated implant that had previously caused a sublingual hematoma during its insertion. The postoperative course was uneventful, no bleeding, infection, or hematoma formation was noted and the patient reported 100% resolution of all symptoms.
