1.Objective To make a computer aided design(CAD)for titanium mandibular prosthesis(Bio-Mechanical Mandible,BMM)upon biomechanical principle of mandible.
目的根据下颌骨生物力学原理对下颌骨缺损钛修复体(生物力型下颌骨Bio-Mechanical Mandible,BMM)进行计算机辅助设计。
2.Methods According to different types of the mandible, mandible angle osteotomy was performed in combination with mandible edge, mandible half ring osteotomy or chin augmentation.
方法根据不同类型的下颌角肥大 ,在下颌骨截骨的基础上联合应用下颌缘截骨、下颌骨半环形截骨以及下颌自体骨隆颏等综合手术方法改善下颌整体形态。
3.Through adjusting jaw bone pattern the face form of changeable person, if mandible slants small, can pass cut mandible bone, make its reach, the mandible bone after reach can appear a bit bigger, a bit more beautiful.
通过调整颌骨形态可改变人的面形,假如下颌偏小,可以通过切割下颌骨头,使它前移,前移后的下颌骨就可以显得比较大一点,比较美观一点。
4.There were 6 cases in mandible body and 1 case in chin, alveolar bone and mandible branch separately.
9例下颌骨骨肉瘤发生于下颌体部6例,颏部、升支、下前牙槽突各1例;
5.Result: ①The midfacial complex was displaced anteriorly, forward growth of mandible was restricted;②The mandible exhibited a downward and backward rotation;③An significant increase was showed on the lower facial height; ④The Class Ⅲ incisor relationship was corrected by anterior displacement of the upper incisors and posterior displacement of the lower incisors.
结果:①上颌向前移位改良生长量,下颌的向前生长受到抑制;②下颌以髁突为中心向下、后旋转,使下颌空间位置发生变化;③下颌的顺时针旋转将造成面下1/3长度增大;④上、下颌前牙发生牙性代偿的掩饰作用。
6.Results From deciduous dentition period to mixed dentition period, the maximum strains (Emax) of all the elements of the mandible were tension strain. The area of all the elements increased except for element 13.The most outstanding increase of area occurred in the anterior and lower component of the chin with counterclockwise rotation to some extent, which may contribute to the skeletal protrusion of the mandible.
结果 从乳牙期到替牙期 ,下颌骨所有单元的Emax均为拉应变 ,除单元 13外 ,其余单元面积均有不同程度增加 ,以颏前下部面积增加最多 ,且有一定的逆时针旋转 ,可能对骨性下颌前突起一定作用。
7.Method Six specimens of mandible were made transparent specimens after the vascular system was perfused with Chinese ink from the common carotid artery,and the blood supply system of mandible were observed and analyzed.
方法将6例墨汁灌注的新鲜下颌骨标本制作成透明标本,对其血供系统进行观察分析。
8.Results 30 cases with lesions of teeth and jawbone were retrospectively studied including periodontal inflammation(n=16),dental cyst(n=6),impact teeth(n=5),giant cell reparative granuloma of mandible(n=1),adenomatoid odontogenic tumor(n=1),mandible bone island(n=1).
结果30例中根尖周炎16例,含牙囊肿6例,埋伏牙5例,下颌骨巨细胞修复性肉芽肿1例,上颌骨牙源性腺样瘤1例,下颌骨骨岛1例。
9.Objective:To study the influence of mandible bone mineral density of ovariectomized adult rats with Bu Shen Decoction(BSD).
目的 :探讨中药补肾方对去卵巢大鼠下颌骨骨密度的影响。
10.Telltale puncture wounds on one of the skulls and gnaw marks on the large mandible reveal that some of the hominids at Dmanisi ended up as cat food.
那个巨大下颚骨曾遭过?咬,另一个人类头骨化石上则发现了剑齿虎犬齿的穿孔,这些透露了德玛尼斯人的下场之一,就是死于虎口。
