Coronectomy is a technique that involves the removal of the crown of the third molar, leaving the root in place. It is recommended when the risks of complete extraction outweigh the benefits, especially in cases where there is a high risk of inferior alveolar nerve (IAN) injury. The success of coronectomy depends on adherence to the operating protocol, which is controlled by the oral surgeon. The aim of this systematic review is to assess the incidence and nature of complications associated with the coronectomy of mandibular third molars. The systematic literature search was conducted according to PRISMA guidelines in MEDLINE (PubMed), and EMBASE (ScienceDirect) databases. A total of 287 titles were identified. 9 studies met the final inclusion criteria. The results showed that coronectomy had a low incidence of IAN sensory disturbance, with 1.6% to 4.3% of cases experiencing such complications, while other studies recorded no cases of sensitivity loss. Infection and dry socket occurred in a small percentage of cases. Coronectomy is a safe and useful technique for treating impacted mandibular third molars. Similar or lower incidence of complications compared to those from extraction were seen. Further prospective homogenous randomized controlled clinical trials are necessary to evaluate the effectiveness of coronectomy in third mandibular molars.

Purpose The purpose of this study was to assess success rates and to report complications of coronectomy of mandibular third molars (M3M), including intra-operative failure, pain, infection, dry socket, inferior dental alveolar (IAN) and lingual nerve (LN) injuries and re-operation rates. Methods Retrospective analysis of 167 coronectomies completed between January 2017 to December 2022 was undertaken. Results The success of coronectomy was 93%. Intra-operative failure was reported to be 3.6% (n = 8). Complications accounted for pain (15%, n = 24), infection (9%, n = 15) and dry socket (3.6%, n = 6). Three patients required removal of M3M root at 3 months (n = 2) and 24 months (n = 1), accounting for 1.8% re-operation rate. A total of number of patients who suffered a nerve injury was 12; three of these were permanent (LN – 1.2%, n = 2; IAN – 0.6%, n = 1), nine were temporary (IAN – 1.2%; n = 2, LN – 2.4%; n = 4; site not specified – 1.8%, n = 3). No patients with intra-operative failure and re-operation suffered IAN or LN injury post-operatively. Conclusion Coronectomy offers a successful strategy for management of high risk M3M. The treatment outcomes can be improved with careful case selection and adjusting surgical technique, including assessment of root morphology, incomplete crown sectioning technique and avoidance of lingual retraction. Reporting of coronectomy success as a factor of surgical outcome, presence or absence of permanent IAN injury, persistent symptoms or any other long-standing complications (such as LN injury), and the need for re-operation accounting for root migration status may be a useful tool to measure coronectomy outcomes.
