The Coronectomy is a popular approach used in surgical removal of an impacted wisdom teeth which is in close proximity to the Inferior alveolar canal. Over the years many surgeons performed this technique to remove mandibular third molars which is in proximity to the IAN canal. The first published description of coronectomy was by Ecuyer and Debien in 1984.The aim of the study was to observe and assess the surgical outcome of coronectomy.Thus this study aims in assessing the prognosis of coronectomy and to evaluate the effectiveness of coronectomy in protecting IAN, to estimate the incidence of injury, to assess the intensity of pain, to ascertain possible post-opeartive complications and the long term behavior of retained roots. Materials and Method: In the present study we included 8 healthy individuals with consent in the age group of 18 to 35 years who were indicated to undergo coronectomy for lower third molars which is nearer to the Inferior alveolar nerve canal under local anaesthesia at department of Oral and Maxillofacial surgery, Coorg Institute of dental sciences. Results & Conclusion: After statistical analysis the result revealed that coronectomy could minimize the injury to Inferior alveolar nerve.Coronectomy seems to be a good option than conventional method when tooth is adjacent to the Inferior alveolar nerve canal.
