Reduced complications by modified and grafted coronectomy vs. standard coronectomy--a case series.

Purpose: The best researched method to decrease nerve injury during the removal of lower third molars is Intentional Partial Odontectomy or Standard coronectomy (SC). Despite an excellent track record, complications still exist. The purpose of this article is to introduce a case series of modified and grafted coronectomy (MGC), designed to minimize the drawbacks of SC.

Materials and methods: Sixteen patients, with total of 20 teeth, were followed for 6 to 49 months. Amendments to SC were intra-surgical stabilization of the root and the creation of a periodontal "scaffold."

Results: MGC showed excellent alveolar bone height and periodontal improvement, with remarkable bone regeneration. No residual root migration was evident on follow up, nor was there inadvertent intraoperative root removal.

Conclusion: This technique may be considered a good alternative to a SC, especially in cases of high risk for, or existent periodontal defects on the distal of second molars or if no residual root migration is desired.
