Purpose: To introduce and validate a new classification system for the inferior alveolar nerve (IAN) injury based on the proximity and positional relation between the tooth root and the inferior alveolar canal (IAC). Methods: In this retrospective study, consecutive patients, who underwent piezosurgery extractions of complicated impacted mandibular third molars from March to November 2014, were...

Purpose The present in vivo study aimed to estimate the prevalence and variation anterior loop of inferior alveolar nerve (IAN) relation mental foramen assess safe zone part mandible for implant placement with cone-beam computed tomography (CBCT) North Indian population. Materials Methodology To conduct this study, 70 patients were selected radiographically evaluated. All CBCT sca...

BACKGROUND Neurological involvement is a serious complication associated to the surgical removal of impacted mandibular third molars and the radiological investigation is the first mandatory step to assess the risk of a possible post-operative injury to the inferior alveolar nerve (IAN). The aim of this study was to introduce a new radiological classification that could be normally used in clin...

To assess and monitor the common event of neurosensory disturbance to the inferior alveolar nerve (IAN) after bilateral sagittal split osteotomy, we used clinical sensory tests and neurophysiologic test sensory action potentials. The diagnostic value of these tests was evaluated by comparing them with the degree of nerve damage reported by patients. Fourteen patients undergoing bilateral sagitt...

Brain-derived neurotrophic factor (BDNF), which is released due to nerve injury, is known to promote the natural healing of injured nerves. It is often observed that damage of mandibular canal induces local sclerotic changes in alveolar bone. We reported that peripheral nerve injury promotes the local production of BDNF; therefore, it was possible to hypothesize that peripheral nerve injury aff...

PURPOSE To estimate oral and maxillofacial surgery reporting of the frequency of temporary and permanent inferior alveolar and lingual nerve damage from lower third molar extraction and injury etiology, and to identify factors associated with injury rates. MATERIALS AND METHODS A postal survey was sent to all members of the California Association of Oral and Maxillofacial Surgeons requesting ...

PURPOSE Extraction of impacted mandibular third molars (M3s) may cause temporary or permanent neurosensorial disturbances of the inferior alveolar nerve (IAN). Although the incidence of this complication is low, a great range of variability has been reported in the literature. Several methods to reduce or eliminate this complication have been proposed, such as orthodontic-assisted extraction, e...

This study aimed to determine whether nerve regeneration by means of an artificial nerve conduit is promoted by ethanol-induced cervical sympathetic ganglion block (CSGB) in a canine model. This study involved two experiments-in part I, the authors examined the effect of CSGB by ethanol injection on long-term blood flow to the orofacial region; part II involved evaluation of the effect of CSGB ...

Neuropathic pain is characterized by spontaneous and provoked pain and other signs reflecting neural damage. Aberrant regeneration following peripheral nerve lesions leaves neurons unusually sensitive and prone to spontaneous pathological activity, abnormal excitability and heightened sensitivity to stimuli. This review covers the current understanding of neuropathic pain after bilateral sagitt...

Premature loss of posterior teeth in the mandible, failure to replace lost teeth as well as systemic factors may result in progressive resorption of the alveolar ridge. At present, oral and maxillofacial surgeons aim to reconstruct the lost bone and masticatory function via posterior mandibular grafting and/or implants. However, anatomic limitations such as the inferior alveolar nerve (IAN) may...
