Inferior Alveolar Nerve Injury

Background and Objectives: Coronectomy is a relatively new method to prevent the risk of Inferior Alveolar Nerve (IAN) injury during removal of lower third molars with limited scientific literature among Nepalese patients. Thus, a study was designed to evaluate coronectomy regarding its use, outcomes and complications.Materials and Methods: A descriptive study was conducted from December 2012 to December 2013 among patients attending Department of Oral and Maxillofacial Surgery, College of Dental Sciences, BP Koirala Institute of Health Sciences, Dharan, Nepal for removal of mandibular third molars. After reviewing the radiograph for proximity of third molar to the IAN, coronectomy was advised. A written informed consent was obtained from the patients and coronectomy was performed. Patients were recalled after one week. The outcome measures in the follow-up visit were primary healing, pain, infection, dry socket, root exposure and IAN injury. The prevalence of IAN proximity of lower third molars and incidence of complications were calculated.Results: A total 300 mandibular third molars were extracted in 278 patients during the study period. Out of 300 impacted mandibular third molar, 41 (13.7%) showed close proximity to inferior alveolar nerve . The incidence of complications and failed procedure was 7.4% among the patients who underwent coronectomy. During the follow up visit, persistent pain and root exposure was reported while other complications like inferior alveolar nerve injury, dry socket and infection was not experienced by the study patients.Conclusion: With a success rate of 92.6% among the 41 patients, coronectomy is a viable alternative to conventional total extraction for mandibular third molars who have a higher risk for damage to the inferior alveolar nerve.JCMS Nepal. 2015;11(3):1-5.

Background. Coronectomy of the wisdom teeth is an alternative surgical procedure to tooth extraction, which aims to preserve the roots of the wisdom teeth in the dental socket after surgical separation of the crown, in order to avoid the injury of the inferior alveolar vascular-nervous bundle. Purpose. Minimizing the damage to the inferior alveolar nerve when extracting lower third molars caused by the intimate relationship between the nerve and the roots of the teeth, by using the technique of coronectomy, or intentional root retention. Material and Methods. Patients who reported to University Dental clinic during the period 2020–2021 for surgical removal of impacted L3M were screened for nerve–root relationship with OPG or CBCT. 15 patients underwent coronectomy as a procedure to remove the crown and upper third of the roots of a lower third molar to reduce the risk of damage to the inferior alveolar nerve. Results. 15 patients were enrolled in this study, with a total of 17 lower third molars. Sixteen sites healed primarily, but in 1 case the sockets on both sides opened and failed to close secondarily. In this case, the root fragments were later removed and found to be mobile. Conclusion. Coronectomies are safer to perform than complete extractions in situations in which the third molar is in close proximity to the mandibular canal. The technique appears to be associated with a low incidence of complications and the removal of remaining roots is required in around 6-7% of cases due to the mesial migration of the fragment and not any symptoms or reinfection.

There is always a nagging question, which heightens my curiosity on the appropriate removal of an impacted third molar in this specific situation: What if you have a carious or beyond-repair second molar or second bicuspid? Will you try to heroically upright the mesially and horizontally impacted third molars? How about resorbed second molar or a third molar in close proximity of mandibular inferior alveolar nerve. Uprighting of mesially impacted tilted molars is the recommended treatment and should be done as soon as possible. If not properly corrected, mesially impacted molars may lead to complications such as elongation of opposing teeth, periodontal problems on the mesial side of the affected teeth, caries in the unerupted molars, temporomandibular disorders and poor oral hygiene. Some clinical procedures have been used to upright the third molar. Is it really worth working to leave the third molar be uprighted or have it surgically removed? As most maxillofacial oral surgeons, prefer
