Influence of first and second premolar extraction or non-extraction treatments on mandibular third molar angulation and position. A comparative study.
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 to create space. The aims of our study are: firstly, to assess the changes in the angulation and position of the 3M in cases treated either with or without extraction of the first or second premolars; secondly, to...

Due to the speculation of third molar role on late incisor crowding, many orthodontists prescribe remov...
متن کاملChanges in the Position of Mandibular Third Molars Following Extraction and Non-Extraction Orthodontic Treatments
Introduction: Impaction of third molars can be associated with a number of sequelae, each requiring a different type of treatment. The purpose of this study was to assess the changes in the position of lower third molars following extraction and non-extraction orthodontic treatments. Methods: Pre- and post-treatment panoramic radiographs of 26 class I malocclusion patients (4 male and 22 female...

objective: extraction of premolars is believed to affect the eruption of third molars. this comparative study aimed to assess the change in angulation of third molars following first/second premolar extraction versus non-extraction orthodontic treatments. methods: this historical cohort study was conducted on patients assigned to three treatment groups: extraction of mandibular first premolars ...
متن کاملThe effect of fixed orthodontic treatment with first premolar extraction on mandibular third molars angulation and retromolar space
Introduction: In most orthodontic patients, mandibular 3rd molars are in early stages of calcification, and prediction of eruption status would be difficult during the course of orthodontic treatment. The aim of this study was to evaluate the effect of first premolar extraction with moderate anchorage on angular changes of third mandibular molar after orthodontic treatment. Materials & Methods...
