“…This would probably cause an incidence of implant fixture displacement inside the body of the mandible [4,5,18]. The displacement of an implant can occur immediately or within a short period due to poor initial implant stability can result from the anatomical variances.…”

“…However, in oral implantology, serious complications might occur in the presence of FOBMD, mainly in the posterior mandibular region of the jawbone. This would probably cause an incidence of implant fixture displacement inside the body of the mandible [4,5]. Such serious complication can occur immediately with the surgical insertion of dental implants or postoperatively because of a deficiency in the primary stability of implants [6,7].…”

International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations. These are because of their ability to osseointegrate directly into the jawbone and then support dental prosthesis. However, a challenged bone condition may prevent the achievement of an optimal implants placement and then cause clinical complications. One of these conditions could be the focal osteoporotic bone marrow defects (FOBMD). Case Report: A 22-year-old female was referred with complaint of missing tooth #35. The void was filled using Bio-Oss® bone grafts. Thereafter, Straumann® ITI Dental Implant (Ø 3.3 mm, Roxolid®, SLActive®) was immediately placed with a torque wrench with adequate primary stability. Four months after placement, the implant was fully integrated and showed good healing. No clinical abnormality was noted. IJCRI publishes Conclusion:The presence of FOBMD does hinder the mechanical stability of dental implants, although it is not negatively affect implants osseointegration from biological point of view. Therefore, we recommend securing the initial stability of dental implants using bone grafting procedure simultaneous the implant placement.(This page in not part of the published article.)

Management of a dental implant displaced into the mandibular bone marrow space: Case reports

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.

“…If FOBMD's are not detected, a displacement of the implant can occur intraoperatively or within a short period of time due to lack of bone for primary stability (Lee et al, 2013). This complication can lead to clinical challenges as difficult uncovering of the implant and also the selection of long-post abutments or even the impossibility to restore it (Sencimen et al, 2011). Due to that FOBMD's are occasionally not included in the differential diagnosis of other radiolucent lesions, knowledge of its radiographic, clinical and histopathological features in association with accurate clinical examination are necessary to distinguish them from other intrabony lesions (Bravo-Calderon et al).…”

SIMANCAS-PALLARES, M.; ARÉVALO-TOVAR, L. & MARINCOLA, M.Focal osteoporotic bone marrow defects on dental implant treated patients: a 5-year period prevalence study. Int. J. Odontostomat., 10(1):23-28, 2016. ABSTRACT:Dental implants are considered the most effective treatment for teeth absence. Nevertheless, there are some bone conditions that could affect the osseointegration process, thus affecting the clinical and radiographic success rates. One of these conditions could be the Focal Osteoporotic Bone Marrow Defects. The objective of this study was to describe the 5-year period prevalence of Focal Osteoporotic Bone Marrow Defects (FOBMD) on dental implant treated patients. descriptive retrospective study was conducted. We systematically reviewed the clinical and radiographic data of treated patients in a Dental Implant Unit since January 2010 through December 2014. Once a FOBMD case was found, a detailed questionnaire was applied to the chart looking for demographic, medical and dental characteristics (clinical and radiographic). Also in a sub-sample histological analysis was carried out. Period prevalence (PP) was estimated calculating proportions and 95 % confidence intervals. Statistical analysis was performed using Stata v. 13.2 for Windows (Stata Corp., TX., USA). FOBMD 5-yPP was 9.52 % (CI 95 %: 6.87-13.5 %). We found 42 defects in 34 patients. Within the FOBMD patients, average age was 55.4±11.9 years, 67.64 % being females. Ninety-seven percent of the defects were located in the lower jaw, 79.41 % unilateral, 69.04 % single missed teeth lesions, 71.42 % affecting molar area and 59.52 % located on the right side of the maxillae. Histological analysis revealed inflammatory cells, dystrophic calcifications, hemorrhagic material and fatty cells for all the cases. FOBMD prevalence is low, so it should be considered as a rare condition but showing an exponential growing trend over the time. With no previous epidemiological data, these findings should be considered as a caution during x-ray examinations and treatment planning, in order to avoid surgical or prosthetic complications. Local factors as previous root canal treatments should be considered when elucidating reasons for its appearance.
