Coronectomy

Coronectomy is studied for people needing lower third-molar surgery who have a higher risk of inferior alveolar nerve injury with complete removal. It applies to an impacted mandibular third molar, not to every wisdom tooth.

Pain was one of the postoperative complications compared between coronectomy and extraction in the review. The pooled research also tracked dry socket and infection after lower wisdom-tooth surgery.

Compared with complete extraction, coronectomy reduced inferior alveolar nerve injury, lingual nerve injury and dry socket in the meta-analysis. Postoperative infection did not differ significantly between the two procedures.

The retained roots may migrate, and later root extraction or surgical reintervention can be needed. Coronectomy therefore has a specific failure rate even though it lowers some complications of complete extraction.

The operation treats an impacted lower third molar by removing its crown rather than extracting the whole tooth. The comparator in the research is complete extraction, with outcomes including nerve injury and postoperative complications.

Follow-up after coronectomy can include monitoring for postoperative infection, root migration, root extraction, surgical reintervention and coronectomy failure. These outcomes were specifically evaluated in studies comparing coronectomy with extraction.

Complete extraction is the direct alternative to coronectomy for the lower third molars studied. The comparison weighs reduced nerve-injury and dry-socket risks against the possibility of root migration and later surgery.

The evidence follows several distinct outcomes after surgery: inferior alveolar nerve injury, lingual nerve injury, dry socket, infection, root migration, root extraction and coronectomy failure. These are more informative than treating recovery as one event.

A coronectomy is a lower wisdom-tooth surgical option that may need later follow-up because retained roots can migrate or require extraction. Complete extraction is the direct alternative considered in the research.
