Background: In modern populations, the impaction rate is higher for third molars than for any other tooth. Due to the speculation of third molar role on late incisor crowding, many orthodontists prescribe removal of third molars before, during or just after orthodontic treatment. Objectives: The aim of this study was to compare whether orthodontic extraction of first premolar lead to any angular changes in second and third molars. Material and method: Orthopantograms of 20 patients undergoing…

Third Molar Angulation Changes in Class II Div I Malocclusion Subjects Treated with Extraction of Four Premolars: A Retrospective Study

Both maxillary and mandibular third molars showed an improvement in their angulations to their respective planes after extraction of the first premolars, however, the results of the study cannot be analyzed to state if the third molar do become fully functional.

[Effects of first premolar extractions on third molar angulations].

Orthodontic treatment involving premolar extractions improves mandibular third molar angulations, and in the extraction group, at the end of the orthodontics treatment, theMandibular fourth molars showed more uprighting than did the maxillary third molars.

Influence of first premolar extraction on mandibular third molar angulation.

Premolar extractions had a positive influence on the developing third molar angulations and nonextraction therapy did not have any adverse effects.

A comparison of the effects of first premolar extractions on third molar angulation.

The results suggest that factors other than first premolar extractions may influence third molar angulation, and on average, the maxillary and mandibular third molars showed an improvement in angulation relative to the occlusal plane.

The effects of first premolar extractions on third molar angulations.

Analysis of the relationship between the inclinations of second and third molars during a two- to 2.5-year period in patients treated orthodontically both with and without premolar extractions revealed that mandibular third molar showed an improvement in angulation relative to the occlusal plane in the first premolar extraction group.

Third molar angulation during and after treatment of adolescent orthodontic patients

The purpose of this study was to analyse the effect of premolar extraction therapy on third molar angulation during active treatment, and to test the significance of such changes on subsequent

It is concluded that extraction of lower premolars and orthodontic treatment to achieve complete closure of the space allowed the positions of many impacted lower third molars to improve significantly.

Maxillary third molar position in Class II malocclusions: the effect of treatment with and without maxillary premolar extractions.

The patients treated with two maxillary premolar extractions presented significantly smaller third molar mesio-distal angulations, that are more favourable to eruption, than those treated non-extraction.

There was no significant correlation between the different conditions of the lower third molars versus lower anterior re-crowding in the absence of tight interproximal incisal contacts; however, a larger sample size is needed to verify such findings.

Mandibular third molar eruption in relation to available space as assessed on lateral cephalograms.

The distance Xi-M2 was found to be significantly greater in individuals with complete dentitions as compared with individuals who had impacted M3s, and mandibular length in males was significantly great in the complete group than in the extraction group, while in females no such difference was recorded.
