Influence of Surgical Technique on Post-Operative Complications in the Extraction of the Lower Third Molar: A Retrospective Study

Abstract

The surgical extraction of the impacted third molar is frequently associated with several complications. The purpose of this study is to assess how two different surgical protocols affect post-operative complications during the extraction of the lower third molars. In order to compare and evaluate two different techniques (triangular flap vs envelope flap), and the relative post-extraction complications, two groups of 150 patients each, underwent to surgical third molar extraction and 60 days of follow-up. A complication rate founded in two groups was respectively 14,00% in group A and 17,33% in group B. There was a strong association between smoking (OR:2.8) and the use of oral contraceptives (OR:1.75) with complications. The age and sex-related incidence of complications in hard tissue healing finds great variability in the literature; the analysis performed on our data did not show a statistically significant association between them. Even though related to a higher incidence of transient changes in sensitivity, it was found that the envelope flap saw a lower percentage of complications. There is still no clarity on which is the best protocol for the extraction of the lower third molar, and the choice often depends on the surgeon’s experience.
