title: [Nerve injury following implant placement: prevention, diagnosis and treatment modalities].
abstract: Nerve injury is a well-known complication following oral and maxillofacial surgery. Direct trauma, inflammation and infection are postoperative neural disturbances main causes. The most inflicted nerves associated with endosseous implant placement are those innervating the mandible: the inferior alveolar nerve, the mental nerve and the lingual nerve. Evaluation of the nerve injury characteristics and severity as early as possible has always imposed a great challenge for clinicians. We demonstrate a reliable yet simple way of dealing with this kind of problem in conjunction with comparing preoperative and postoperative sensation of the chin, the tongue and the lower lip. On the other hand, it is considerably important to take preventive measures for such injuries by using appropriate radiographic images. If a nerve damage has occurred, best prognosis is to be expected by early and appropriate treatment. It is imperative to treat such injuries in four months following the injury, otherwise a permanent nerve damage may occur. Further investigation of nerve damage risks following implant placement should be performed in order to enable patient to decide whether having implants dependent rehabilitation or choosing an alternative.
