Background/Objectives: Coronectomy is an alternative to complete third molar extraction to reduce the risk of inferior alveolar nerve injury. This systematic review of systematic reviews evaluates re-intervention rate, timing, and indications after mandibular third molar coronectomy. Methods: A systematic search following PRISMA guidelines was conducted across Scopus, MEDLINE/PubMed, BioMed Central, Web of Science, Cochrane Library and PROSPERO. Studies reporting re-intervention rates after at least six months from coronectomy were included. Data extraction focused on re-intervention timing, indications, and complications. Results: Six systematic reviews, including 5896 subjects and 7913 successful coronectomies (not requiring immediate tooth extractions), were analyzed. The overall re-intervention rate was 4.45%, with timing ranging from six months to ten years (mean: 10.4 months). Root exposure (16.76%) was the primary cause, followed by infection (4.55%) and pain (2.84%). Root migration (12.20%) was common, while inferior alveolar nerve injury remained rare (0.76%). Conclusions: Coronectomy is a viable alternative in high-risk cases, with a low re-intervention rate. Root migration and exposure require long-term follow-up. Standardized imaging protocols and refined re-intervention criteria are needed. Full article

This systematic review aimed to review the literature on the coronectomy technique and evaluate the incidence of success and complications as a surgical approach for inferior third molars. Online databases were searched for data on the frequency of inferior alveolar nerve damage, lingual nerve damage, root migration, pain, infection, dry socket, and extraction of the remaining root, and data on the necessity of reintervention were also extracted. Randomized clinical trials, controlled clinical trials, prospective cohort studies, and prospective and retrospective studies with or without the control group were intercepted. This systematic review was registered in PROSPERO (CDR 42020135485). Sixteen papers analyzed 2176 coronectomies in total, and only five of them were judged as appropriate according to methodological quality assessment. The incidence of inferior alveolar nerve injury was documented in 0.59% of the procedures, lingual nerve injury in 0.22%, infection 3.95%, dry socket 1.12%, extraction of the root 5.28%, and reintervention 1.13%. The pain was the most reported, in 22.04% of the population. This study provides an overview of the clinical success and complications of coronectomy, and their prevalence. A coronectomy may be considered a low-risk procedure and an option for treatment to avoid potential damage to nervous structures. However, patients should still undergo a full screening and evaluation of postsurgical procedures. Full article
