          Abstract

          In oral implantology, the most serious complications occur intraoperatively or within a short period. We describe an unusual case of focal osteoporotic bone marrow defect involving dental implant in the posterior mandibular region of the adult woman. Despite the fact that this condition requires no treatment, it could lead to the displacement of the dental implant. Additionally, this case report reinforces that histopathological analysis is mandatory for precise diagnosis of the radiolucency into posterior mandibular region of the adult woman associated or not with dental implant placement.

          Intraoperative complications during oral implantology.

          Joana Lamas Pelayo, Miguel Peñarrocha-Diago, Eva Martí Bowen … (2008)
          Dental implant placement is a controlled, programmed surgical procedure, not without its complications. The aim of the present paper is to study the intraoperative complications in implant surgery, carrying out a review of articles appearing in Medline over the last 10 years. Among the intra operative complications related with surgery, hemorrhagic accidents occur most frequently in the interforaminal region, since the majority of the vascular branches enter the mandibular bone in this region. Nerve damage can arise as a consequence of inferior alveolar nerve transposition or lateralization; or the excessive intrusion of drills or implant fixture into the mandibular canal. Mandibular fractures secondary to implant placement occur more easily when placing implants in atrophic mandible. Occasionally, incorrect positioning or lack of relative parallelism in the placing of the implants causes damage to an adjacent tooth. Absence of primary stability may occur as a result of overworking the implant bed during preparation, also to poor bone quality, and more frequently to immediate post-extraction implantation. Another possible complication is the migration of implants into the maxillary sinus.

            Displacement of dental implants into the focal osteoporotic bone marrow defect: a report of three cases

            Sang-Chil Lee, Chang-Hwa Jeong, Ho-Yong Im … (2013)
            Focal osteoporotic bone marrow defect (FOBMD) is a radiolucent area corresponding to the presence of hematopoietic tissue rarely found in the jaws. FOBMD is most commonly located in the mandibular edentulous posterior area of a middle-aged female. From November 2011 to November 2012, we experienced three cases involving removal of implants that had accidentally fallen into the FOBMD area. All patients happened to be female, with a mean age of 54 years (range: 51-60 years). One case involved hypoesthesia of the lower lip and chin, while two cases healed without any complication. Displacement of an implant into the FOBMD area is an unusual event, which occurs rarely during placement of a dental fixture. The purpose of this study was to report on three cases of FOBMD and to provide a review of related literature.

              Focal osteoporotic bone marrow defects of the jaws.

              M S Makek, G E Lello (1986)
              Twenty focal osteoporotic bone marrow defects of the jaws were analyzed clinically, histologically, and radiographically; the findings were compared with those from all known published cases. Radiologic and clinical criteria that are useful for making a definitive diagnosis are discussed, and five radiologic categories are proposed.
