It seems to me the worst comment on dictatorships is that presidents of democracies can laugh, while dictators always look so serious—with a protruding jaw, a determined chin, and a pouched lower lip, as if they were doing something terribly important and the world could not be saved, except by them.

在我看来，对于独裁统治最尖锐的批评莫过于：民主制度下的总统会笑，而独裁者却总是一脸严肃——向外突出的颌骨，硬梆梆的下巴，弯成袋状的下唇，似乎他们在做着非常了不得的事情，只有他们能拯救世界。

The adhesion region between two adjacent teeth on the 3D dental model is first detected by exploiting the minimum principal curvature information. Then, the adhesion region is cut off and the tooth profile opening caused by the removal of the adhesion region is filled with triangular patches adopting a local optimization scheme, it is then refined to form an intermediate restoration surface patch. The final restoration result is obtained by minimizing the surface energy to reflect the bio-characteristics of the single tooth.

根据三维牙颌模型的形态特征，采用基于曲面最小主曲率的方法对粘连区域进行准确的检测提取；对删除齿间粘连区域后生成的齿间开口利用局部最优化权值规则进行剖分并细分优化，生成"中间"恢复曲面；根据牙齿的生理医学特征，以齿间开口的边界信息为约束条件，采用基于最小化曲面能量函数的方法对"中间"恢复曲面进行变形调整，实现单颗牙齿缺失形状的准确恢复。

Objective To explore the indication, advantage and disadvantage of modified or classical technique of intraoral sagittal split ramus osteotomy for correction of mandibular prognathism.
