Abstract
|
|
|
When an implant fixture is displaced to the bone marrow defect site of the mandible, damage to the inferior alveolar nerve may occur.
To minimize postoperative side effects, an accurate radiological evaluation should be made and the best method of removal should be considered. Here, we report two cases of implant removal in patients referred to our hospital who had an implant fixture displaced by a mandibular bone marrow defect, and we also propose a standardized method for removal of the implant. Two patients were referred to our clinic with displacement of an implant fixture to the mandibular bone marrow space. For removal of the implant, a trapezoidal bone window was designed with the buccal cortical bone of the drilling hole as the superior margin. An osteotomy was performed on the cortical bone. The implant was gently moved upwards and removed. Healing was uneventful with no neurological complications.
