Displacement of dental implants into the focal osteoporotic bone marrow defect: a report of three cases
A 51-year-old woman with medical history of myoma uteri was referred by a private dental clinic for the management of displacement of implant fixture in the left mandible posterior area on November 28, 2012. Three hours earlier, one implant accidentally fell into the mandible body of the #36 area during implant surgery.() The CBCT image of the jaws showed radiolucency with quite ill-defined and irregular borders located from the premolar area to the left midbody of the #36, #37 edentulous regions and indicated the implant location to be near the mandibular inferior border. The removal of implant fixture followed the same procedure as that of case 1. The implant was 4.0 mm wide and 10.0 mm long. Healing proceeded uneventfully during the 3 months' follow-up.
