Changes 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...

متن کاملcomparison of changes inmandibular third molar angulationfollowing first/second premolar extraction versus non-extraction orthodontic treatments
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 کاملEvaluation of changes in the vertical facial dimension with different anchorage systems in extraction and non-extraction subjects treated by Begg fixed appliances: a retrospective study.
The aim of the study was to evaluate and compare the effects of mesial movement of the maxillary and mandibular molars on the facial vertical dimensions following orthodontic treatment. Patients with an Angle Class I malocclusion were treated by four first premolar extractions and Begg fixed appliances (moderate and maximum anchorage groups), while those with an Angle Class II malocclusion were...
متن کاملFirst or second premolar extraction effects on facial vertical dimension.
If the concept of mesial movement of molars to reduce the "wedge effect" and decrease facial vertical dimension (FVD) is valid, it is important to investigate the effect of first (P1) and second premolar (P2) extraction on FVD. This study compares the mesial movement of molars and changes in FVD between P1 and P2 extraction groups in Class I malocclusion with a hyperdivergent facial type. We co...
