Severe lower crowding with normal maxillary arch and nasolabial angle. 严重的低拥挤与正常上颌牙弓和鼻唇角。
The low angle group showed maxillary prognathia and small mandibular angle. 低角组上颌前突,下颌角缩小。
Some problems about the operation of maxillary sinus and the selection of the site and angle of maxillary sinus puncture are discussed. 并对与上颌窦手术的径路有关问题,上颌窦穿刺术的进针点和角度的选择进行了讨论。
A preliminary study about the timing of maxillary protraction therapy for Angle ⅲ malocclusion AngleⅢ患者上颌前牵引矫治时机的初步探讨
Conclusion: Expanding maxillary posterior arch width in Angle ⅱ 1 patients may be one of the important methods to harmonize upper and lower arch form. 结论临床上扩展AngleⅡ~1的后上牙弓宽度可能是协调上下牙弓形态的重要措施之一。
To evaluate the treatment effect of maxillary protraction on skeletal class ⅲ high angle cases in mixed dentition. 【目的】探讨上颌后牙牙合垫联合前方牵引治疗替牙期骨性Ⅲ类错牙合高角病例的效果及矫治机理。
Conclusion: The combination of rapid maxillary expansion and maxillary protraction is an effective appliance in the treatment of Angle class ⅲ patients in the mixed dentition phases. 结论:在替牙期联合应用前方牵引器与扩弓器治疗安氏Ⅲ类错牙合能刺激上颌骨前移,抑制下颌骨的前方发育,可有效矫治安氏Ⅲ类错牙合。
The heights and lengths of the vault, mid facial heights and maxillary lengths, and facial angle, palatal and cranial base angle were measured in different periods after surgical fixation of the sutures. 术后不同时期测量颅穹窿长度、高度、面中部高度、上颌骨长度、面角、腭角和颅底角。
Roentgenographic Cephalometry study of the Relationship Between Maxillary Complex and Skull-Mutuality and Compensation Mechanism Between Angle and Line-length 上颌复合体与颅部位置关系的头影测量研究&角度与线距的相关关系及补偿机制
The Clinical Investigation of the Modified Fixed Reverse Twin-block Appliance Combined with Maxillary Protraction in Treatment of Children Angle ⅲ Anterior Crossbite 改良固定反式Twin-block矫治器联合前牵引矫治儿童AngleⅢ类错(牙合)的临床研究
The clinical investigation of the maxillary protraction in treatment of children Angle ⅲ anterior crossbite 前方牵引矫治儿童安氏Ⅲ类错牙合的临床研究
Results It was found that in dogs the opthalmic artery originated from the maxillary artery, and that its root formed an angle with infraorbital artery. 结果在犬的解剖中发现眼动脉发自上颌动脉,起点处与眶下动脉成夹角。
Well constructed three-dimensional finite element models of maxillary, maxillary first permanent molar and its periodontal ligament, band-buccal tube and various angle face-bow was established, furthermore, these models had a properly geometric compat and mechanical similar. 2. 结果:1.建立了上颌骨、上颌第一恒磨牙及其牙周膜、带环颊面管及口外弓的三维有限元模型,所建的模型具有良好的几何相似性及力学相似性。
The maxillary complex showed parallel anterior displacement and there was no obviously change in the basilar-maxillary angle. 上颌基本为平行向前移动,颅底角变化不明显。
