extraction does not result in any difference in third molar impaction. Materials and Methods …

Introduction: The purpose of this study was to identify risk factors for mandibular third-molar
impaction in adolescent orthodontic patients. Methods: Radiographs made before (T1) and …

The purposes of this study were to confirm that premolar extraction treatment is associated
with mesial movement of the molars concomitant with an increase in the eruption space for …

The purpose of this study was to identify risk factors for maxillary third molar impaction in
adolescent orthodontic patients. Radiographs made before treatment (T1) and after …

The aim of this study was to investigate the differences between two groups of patients with
either erupted or impacted mandibular third molars before and after orthodontic treatment …

Introduction: Third molars often become impacted because of lack of space for their eruption.
Because the third molars play an important role occlusally, premolars or second molars are …

The mandibular third molar (3M) is the tooth that is most often impacted, with lack of space
being one of the reasons. In some orthodontic treatments, premolars are extracted in order …
