舌骨

MAIN OUTCOME MEASURES: Height of maxillary sinus, buccolingual bone thickness at implantation sites and bone density.

主要观察指标：上颌窦高度，植入部位颊舌侧骨厚度，骨密度。

After obtaining the nasorbital image fitting data as the reference to the simulation and mesiodistal to different angles of the post-core angle.

图像拟合之后获取颌骨形态参数，以此为参照模拟颊舌向及近远中向不同角度的桩核冠修复角度加力后寻求安全角度范围。

Its mechanism is downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors and the forward growth of maxilla.

FR-Ⅲ是矫治替牙期前牙反的理想方法之一，其机理是下颌骨向下、向后旋转，舌倾下切牙，唇倾上前牙，促进上颌骨向前生长。

Results Normal overbite and overjet were established, the mandibular dentition was distalized and significantly uprighted, a slight proclination was found in the upper anterior teeth, the relative relationship of upper and lower lip get some improvement but few for skelecton.

结果 前牙均建立了正常的覆覆盖关系，下前牙舌侧倾斜、移动及下磨牙远中竖直、移动明显，上前牙轻微前倾，上下唇相对位置获得改善，骨改变不明显。

Congenital element, because be born before, of pregnant woman hidebound, systemic sex disease, certain and familial genetic element (if the tooth is mixed,the character of jaw bone and size often affect a tooth, cause dental amlposition or jackknife to wait); Acquired element, basically be undesirable habit (consistent side sex is masticatory, buccal breath, make force of parity of tongue, lip, buccal share is destroyed, those who cause jaw growth is not not well-balanced, harmonious) with all sorts of tooth disease.

先天因素，由于出生前，孕妇的营养不良，全身性疾病，某些家族的遗传因素（如牙齿和颌骨的性状和大小常常影响牙位，造成牙齿错位或重叠等）；后天因素，主要是不良习惯（如一侧性咀嚼，口呼吸等，使舌、唇、颊部分均势力量受到破坏，导致面颌发育的不匀称、不协调）和各种牙病。

Each millimeter of alveolar bone loss was associated with a more than fivefold increase in the risk of tongue cancer, reported Mine Tezal, D.D.S., Ph.D., of the Roswell Park Cancer Institute, and colleagues, in the May issue of the Archives of Otolaryngology Head and Neck Surgery.

罗斯威尔帕克癌症机构口腔外科博士Mine Tezal说伴随着每毫米的齿槽骨缺失损伤患舌癌的风险将增加5倍，并在5月份的耳鼻喉科与头与颈外科学术会议同行之间进行探讨。

Each millimeter of aleolar bone loss was associated with a more than fiefold increase in the risk of tongue cancer, reported Mine Tezal, D.D.S., Ph.D., of the Roswell Park Cancer Institute, and colleagues, in the May issue of the Archies of Otolaryngology Head and Neck Surgery.
