“…Inferior alveolar nerve injury can cause paresthesia to complete numbness and/or pain [54] in the region of the skin of the mental area, the lower lip, mucous membranes, and the gingiva as far posteriorly as the second premolar [55]. Furthermore this commonly interferes with speech, eating, kissing, make-up application, shaving and drinking [56]. The injury of the lingual nerve leads to numbness of the ipsilateral anterior two thirds of the tongue and taste disturbance [50].…”

ObjectivesThe purpose of present article was to review impacted mandibular third molar aetiology, clinical anatomy, radiologic examination, surgical treatment and possible complications, as well as to create new mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results.Material and MethodsLiterature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were mandibular third molar, impacted mandibular third molar, inferior alveolar nerve injury third molar, lingual nerve injury third molar. The search was restricted to English language articles, published from 1976 to April 2013. Additionally, a manual search in the major anatomy and oral surgery journals and books was performed. The publications there selected by including clinical and human anatomy studies.ResultsIn total 75 literature sources were obtained and reviewed. Impacted mandibular third molar aetiology, clinical anatomy, radiographic examination, surgical extraction of and possible complications, classifications and risk factors were discussed. New mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results was proposed.ConclusionsThe classification proposed here based on anatomical and radiological impacted mandibular third molar features is promising to be a helpful tool for impacted tooth assessment as well as for planning for surgical operation. Further clinical studies should be conducted for new classification validation and reliability evaluation.

“…This commonly interferes with speech, eating, kissing, make-up application, shaving and drinking, in fact, just about every social interaction we take for granted. 2 Following oral implant rehabilitation, the patient usually expects and experiences significant improvements, not only regarding jaw function, but also in relation to dental, facial, and even overall body image. 3 Thus these injuries have a signifi cant negative effect on the patient's quality of life and the iatrogenesis of these injuries compounds the negative psychological effects for these injuries.…”

Introduction Nerve injury during implant placement is a preventable, serious complication with major medico-legal implications. The incidence of implant related inferior alveolar nerve (IAN) injuries varies from 0-40%. This article presents four cases of IAN injury following mandibular implant placement with early removal, referred to the oral surgery department, King's College Hospital, London. Objectives To assess sensory disturbance and recovery in patients with implant related IAN injury and assess whether early removal of the implants promotes neural recovery. To present recommendations on how to best deal with suspected/actual nerve injuries and prevent their occurrence. Methods Over the last two years, four patients referred for specialist opinion to the oral surgery department were identifi ed as having sustained implant related IAN injury with early removal (18 hours to four days post-injury). Data were collected by referral to health records. Results All patients suffered from numbness of the affected inferior alveolar dermatome with three out of four cases also experiencing some form of neuropathic pain. Cases 1 and 2, who had their implants removed at 18 and 36 hours post-injury respectively, regained almost complete sensory recovery. Case 1 also had adjunctive NSAID and steroid therapy. Cases 3 and 4 suffered complete numbness in the inferior alveolar dermatome and did not experience any improvement in sensation following removal of their implants at two and four days post-injury respectively. Both patients with signifi cant persistent neuropathy (Cases 3 & 4) reported functional problems. Conclusion This cohort of patients may demonstrate that early removal of implants associated with IAN injury (less than 36 hours post-injury) may assist in minimising or even resolution of IAN neuropathy. Adjunctive corticosteroid and high dose non-steroidal anti-infl ammatory therapy also appears effective. Implant related IAN injury is a preventable, elective procedure and a suggested protocol of management of suspected injuries, for dental practitioners, is presented.

“…In fact, just about every social interaction we take for granted. 3 These injuries therefore have a significant effect on the patient's quality of life and the iatrogenesis of these injuries may lead to further significant psychological effects. 4 Background The incidence of implant-related inferior alveolar nerve injuries (IANI) is steadily increasing within the UK population.…”
