The coronectomy technique for lower third molars: past and present

Aim To discuss the past and present evidence for the coronectomy technique for third molars. Materials and Methods A review of the past and present literature related to the healing of extraction sockets in the presence of root fragments. Results High-quality research studies surrounding the coronectomy procedure are lacking and it is important therefore that surgeons are aware that change of practice is not yet supported. The long-term consequences, in terms of infection or other, are not known as study follow-up is short. Conclusion If coronectomy is to be considered then the authors would suggest that this is only for patients at high risk of potential nerve injury and that the patient is made aware of the risk of failure, the possible need for re-operation and our lack of knowledge of long-term consequences.
