“…As previously reported by Theisen et al,14 when the location of the inferior alveolar canal could not be delineated on a panoramic radiograph, large medullary components could be detected on the CT section. Thus, additional radiographic evaluations such as preoperative CT may be necessary for patients whose molar teeth were extracted much earlier in their life, particularly among postmenopausal women.…”

“…Failure of initial implant stability can result from low trabecular bone density, decreased thickness of the cortical bone, anatomical variances, and osteopenia or osteoporosis; problems related to the use of surgical technique by an inexperienced operator, such as inadequate planning, overworking of the implant drilling, mishandling, and incorrect manipulation, have also been suggested as possible factors5,6. According to Theisen et al,14 during the tightening of the healing screw, the implant was displaced inferiorly into the preparation, and attempts to remove the screw and retrieve the implant body resulted in the further inferior displacement of the implant body. One case (case 1) exhibited hypoesthesia of lower lip and chin.…”

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.

“…For example, in the posterior mandible, cancellous bone is more abundant and has bigger intratrabecular spaces but less dense than in anterior mandible [58,59]. In some cases with low density bone, the twist drills may drop into trabecular bone spaces during preparation thus leads to the displacement of the implants deeper than planned [60].…”

ObjectivesThe purpose of present article was to review aetiological factors, mechanism, clinical symptoms, and diagnostic methods as well as to create treatment guidelines for the management of inferior alveolar nerve injury during dental implant placement.Material and MethodsLiterature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were inferior alveolar nerve injury, inferior alveolar nerve injuries, inferior alveolar nerve injury implant, inferior alveolar nerve damage, inferior alveolar nerve paresthesia and inferior alveolar nerve repair. The search was restricted to English language articles, published from 1972 to November 2010. Additionally, a manual search in the major anatomy, dental implant, periodontal and oral surgery journals and books were performed. The publications there selected by including clinical, human anatomy and physiology studies.ResultsIn total 136 literature sources were obtained and reviewed. Aetiological factors of inferior alveolar nerve injury, risk factors, mechanism, clinical sensory nerve examination methods, clinical symptoms and treatment were discussed. Guidelines were created to illustrate the methods used to prevent and manage inferior alveolar nerve injury before or after dental implant placement.ConclusionsThe damage of inferior alveolar nerve during the dental implant placement can be a serious complication. Clinician should recognise and exclude aetiological factors leading to nerve injury. Proper presurgery planning, timely diagnosis and treatment are the key to avoid nerve sensory disturbances management.

Dental computer assisted tomography (Dental CT) represents a valuable addition to the diagnostic spectrum for planning oral and maxillofacial surgery. High resolution CT and specially designed computer software allow representation of the jaws in different planes that are easy to match. They further allow the display of very small structures relevant to oral surgical interventions and reveal their spatial relationship in three dimensions. Thus communication between dentists and radiologists may be intensified and supported by usage of modern telecommunication systems. Dental CT is indicated, when clinical and conventional radiological techniques will not allow exact interpretation of the situation. It is modern oral implantology that primarily benefits from computer software enabling the assessment of surgical sites in the presurgical phase. Such planning was not yet possible using two dimensional radiographic techniques. The dental-implantological part expects from radiography sharply defined contours of the external bony contours and the mandibular canal, exactly defined relation between slices and planes, no distortion in the orthoradial planes, tools for reliable measurements of distances, angles and volumes, possibility to transmit pictures electronically or on hardcopy without loss of quality.
