EXTRATION OF MANDIBULAR THIRD MOLARS, A CORRELATION BETWEEN THE SURGICAL TECHNIQUE AND WINTER’S
Total and partial impaction of the teeth is considered to be a developmental anomaly, that can affect any tooth in both deciduous and permanent dentition, but according to a large number of dental authors it is mostly associated with the mandibular third molars. Its multifactorial etiology, diagnostics, oral surgical approach and techniques can increase the difficulties of this problem which is encountered in the everyday oral surgical practice.The selection of the appropriate oral surgical technique mostly depends on the various positions in which the total or partial impacted mandibular third molar may appear and his correlation with the adjacent anatomical structures, thus leading to different diagnostic and therapeutic problems.This study includes 80 patients, divided in two groups of 40 patients, where one group is diagnosed with a total impaction and the other group with a partial impaction of the mandibular third molars.After a statistical analysis of the obtained data was performed with the help of appropriate world renowned classifications concerning the position of the impacted mandibular third molars, we came to the following results: according to Winter’s classification, the impacted molars where dominantly in a vertical position; Axhausen’s flap design was dominantly a method of choice; buccodistal osteotomy is the most frequently used technique; the impacted molars presented a convergent anatomical configuration of the roots in most of the cases.
