Facilitation of Orthodontic Treatment

In patients who require retraction of first and second molars by orthodontic techniques, the presence of impacted third molars may interfere vith the treatment. It is therefore recommended that impacted third molars be removed before orthodontic therapy is begun.
Another consideration is that, after orthodontic treatment has been concluded, there may be crowding of the mandibular incisor teeth. This has been attributed to the mesial force transmitted to the molar and premolar teeth by impacted third molars, especially mesially inclined impactions. 11,12 Several other factors influence crowding. Growth of the maxilla stops before growth of tile mandible, If the upper and lower incisors are in a proper overbite and overjet relationship,-and if tile mandible continues to grow’ after the maxilla stops growing, tile mandibular incisors then become crowded to 3rCOJllIl1Odate the constriction imposed on them by the maxillary incisors: This explanation appears sound, because CfOW. FIG: 9-8
