In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

One is at low growth temperature, the origin of mound formation can be attributed to an intrinsic growth instability of a singular surface in the presence of so-called Ehrlich-Schwoebel step-edge barrier, which inhibit the downward movement of adatoms at surface step-edges. The other is at high temperature, or at low Ⅴ/Ⅲ ratio, the reason of mound formation is related to phosphorus deficiency.
