The morphologic analysis and the clinical value of mandibular impacted teeth 下颌阻生齿形态分析及其临床意义
Conclusion The ribbon reinforced resin splint was satisfactory in splinting the mobile mandibular anterior teeth. 结论应用强力纤维强化树脂夹板固定下颌前牙可获得较满意的临床效果。
Conclusion To grasp accurately the anesthesia positions of maxillary and mandibular teeth can decrease the patient pain. 结论准确掌握上、下颌牙麻醉点的解剖学位置,可以减轻病人在诊治过程中的痛苦。
RESULTS: Contrary to the normal occlusion, the mandibular teeth of occlusal model with severe attrition generally bear the torque force with the crown distally and the root medially. 结果:近远中方向上,重度磨耗牙合下颌牙列中各牙均受到冠向远中、根向近中的转矩力作用。
The applied anatomy about anesthesia position in maxillary and mandibular teeth 上、下颌牙麻醉点的应用解剖
The distribution tendency of stress on edentulous tissue for the complete dentures formed by two teeth arrange method s were coincident on the whole, but the stress values were different, value for maxillary teeth arrange method were larger then that for mandibular teeth arrange method. 两种排牙法对无牙下颌支持组织所产生的应力分布趋势基本一致,但上颌排牙法所产生的应力值明显大于下颌排牙法。
In the general significance, occlusion may contain two meanings: One is the linking contact between the maxillary and the mandibular teeth, the other is that in the movement of mandible. 一般意义上的咬合可包含两个方面的含义:一是上下颌牙齿的咬合接触,二是在下颌运动中上下颌的牙齿咬合接触。
Morphology Research of Mandibular Anterior Teeth 下颌前牙根管的形态学研究
Results The anesthesia positions of maxillary and mandibular teeth were determined. 结果通过观测,确定了上、下颌牙麻醉点的解剖学定位。
68 Cases of orthognathic surgery on alveolar malocclusion of both maxillary and mandibular anterior teeth were re-ported. 本文报告68例非颌骨性的上下前牙牙槽性错(牙合)畸形的外科正畸手术。
The anesthesia effect in maxillary teeth was better than that in mandibular teeth. 上颌牙的麻醉效果好于下颌牙。
Objective: To evaluate the effect of dexamethasone on prevention of postsurgical complication of mandibular impacted teeth removal. 目的:探讨地塞米松对下颌阻生智齿拔除术后并发症的预防。
Besides, mesial-distal root canal walls of mandibular incisor teeth are thin. 同时下颌切牙根管壁近远中向薄。
Objective To study the stress distribution situation in the mandibular anterior teeth under the condition of vertical loading and oblique loading, when its periodontal supporting tissues and central incisor are absorbed to three different kinds of degree. 目的:研究下颌前牙正常牙周组织和两侧中切牙三种不同程度牙槽骨吸收后,轴向载荷和斜向载荷作用下,牙体组织的应力变化情况。
