National survey: Avulsion of included wisdom teeth in mandibular orthognathic surgery

Introduction. There is no recommendation concerning wisdom teeth (WT) extraction in mandibular orthognathic surgery. We carried out an investigation among the members of the French Society of Stomatology and Oro-maxillofacial Surgery (SFSCMFCO), in order to evaluate the practices and habits of maxillofacial surgeons in this field. Materials and methods. We emailed the 424 members of the SFSCMFCO with a questionnaire. Results. We obtained 143 feedbacks that could be exploited. In total, 72.5% of practitioners prefer WT to be extracted before performing a bilateral sagittal spilt osteotomy (BSSO). In this case, a period of 6 months between the two surgeries was considered as desirable by more than 70% of the surgeons. In total, 74.6% of the surgeons thought that the presence of WT could make a BSSO more complicated. However, 73.9% of the surgeons would not postpone the BBSO in a patient ready for surgery but with remaining impacted WT. Discussion. A majority of surgeons think that the presence of impacted WT may complicate a BSSO and increases the risk of bad split. Most of the authors recommend extracting the impacted WT 6 months before BSSO at least. However, these potential complications are easy to overcome and don't compromise the final result. Therefore, we think that impacted WT should not delay a BSSO if the orthodontic preparation makes the patient ready for surgery. (C) 2016 Elsevier Masson SAS. All rights reserved.
