Conclution More mesially inclined maxillary molars are likely to be associated with third molar eruption.
结论第三磨牙萌出与上颌第一、第二磨牙较大的近中倾斜有关。
Objective To assess the treatment method and outcome of mesially or horizontally impacted mandibular molars.
目的探讨下颌前倾、水平阻生磨牙的正畸治疗方法，评估其效果。
Objective: To measure changes in angular position and eruption status of mesially impacted mandibular third molars (M3) during 3-year follow-up period.
目的：3年随防观察近中阻生的下颌第三磨牙萌出情况与其倾斜角度的关系。
The third premolar and the first molar of miniature pigs inclinate mesially, and are similar with the first premolar and the first molar of the human beings.
第三前磨牙与第一磨牙长轴为近中倾斜，与人类第一前磨牙和第一磨牙近似。
Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16 ~ 25 years). This inclination increased with age.
结果上颌第三磨牙萌出组与未萌出组相比，上颌第一磨牙和第二磨牙更向近中倾斜，而且随年龄的增加倾斜度也变大。
Conclusion This reflects that the second molars could move mesially during treatment in the second premolars extraction subjects, which can lead to the increase of the retromolar space.
结论：第二前磨牙拔除患者可发生第二磨牙近中移动，导致磨牙后间隙增加。
Conclusion This reflects that the second molars could move mesially during treatment in the second premolars extraction subjects, which can lead to the increase of the retromolar space.
结论：第二前磨牙拔除患者可发生第二磨牙近中移动，导致磨牙后间隙增加。
