Basal skull fracture with dural tear at cribriform plate of ethmoid bone and intracerebral cyst filled with air were found during operation. 手术中发现颅底筛骨筛板处有骨折并硬脑膜裂开,及充满气体之大脑囊肿。
The Study of Dental Arch and Basal Bone Morphology in Angle's Class ⅱ, Division 1 Malocclusion 安氏Ⅱ~1类错(牙合)牙弓与基骨形态的研究
Objective To analyze dental crowding degree and its relationship with all kinds of indexes of tooth and basal bone. 目的分析牙齿和基骨的各项指标对牙列拥挤度的影响。
Objective The purpose of the study was to evaluate the effection of using rapid maxillary expansion accompanied with straight-wire appliance on dental arch and basal bone. 目的评价上颌快速扩弓和直丝弓矫治器联合应用对牙弓、基骨宽度的影响。
Results show, the increment of width of basal bone and arch has statistically significant difference. 结果表明治疗后比治疗前,牙弓、基骨的宽度增加,统计学分析有显著性差异。
Methods 143 patients with hypertensive cerebral hemorrhage in basal ganglia were treated by small bone window craniotomy after the foci were simply aligned by CT. 方法根据设定标准选择性收治高血压基底节区脑出血病人,采用CT简易定位小骨窗开颅血肿清除术治疗143例。
Conclusion ( 1) Insufficient basal bone width and excessive tooth size were the main causes of tooth crowding and tooth removing treatment. 结论:1.基骨宽度不足、牙齿过大是造成牙列拥挤和拔牙矫治的主要原因。
Analyses of measurements on the tooth, dentition and basal bone of Normal Occlusion of Han People in Yunnan 云南省汉族正常(牙合)牙、牙弓、基骨的测量分析
Results: FR ⅲ can correct the abnormal sagittal relationship of the basal bone between maxilla and mandible. The main changes were the downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors. 结果:FR-能矫正上下颌基骨异常的矢状关系,主要变化是下颌骨向下、向后旋转,改变下颌骨生长的方向,同时使下颌切牙舌倾、上前牙唇倾,上颌骨向前生长。
Displacement of X axis: The maximum lateral displacements were at the first molar of basal bone,-20.783μ m. X轴方向的位移:横向最大位移在第一磨牙基骨,为-20.783μm;
Conclusion: For the hypertensive hemorrhage of basal ganglia region at early stage, the small bone window operation under microscope is a safe, easy, speedy, and effective method. 结论:早期小骨窗显微镜下行血肿清除术是治疗基底节区高血压脑出血的一快速、安全、有效的方法。
Results The length and width of basal bone have no significant differences. 基骨宽度和基骨长度的差异无显著性;
Conclusion The use of rapid maxillary expansion accompanied with straight-wire appliance can greatly increase the width of dental arch and basal bone, it has been proved a practical method for arch expansion suitable for patients with dental crowding. 结论上颌快速扩弓和直丝弓矫治器联合应用能使牙弓、基骨宽度快速增加,对牙列拥挤病例是一种安全、有效的治疗方法。
The osteolytic destruction of the bone cortex of basal part and diaphysis, radioactive bone spicule and Codman triangle in the periosteum; 基底部及骨干骨皮质溶骨性破坏,骨膜出现放射状骨针及Codman三角;
Conclusion We established the normal range of teeth, dental arch, basal bone and Howes 'values of Yunnan youth. 结论①建立云南省汉族牙、牙弓、基骨和Howes值的正常范围;
Combined cultivation of nano-collagen basal bone and human bone marrow derived mesenchymal stem cells 纳米晶胶原基骨与人骨髓间充质干细胞的复合培养
Objective To evaluate the relationship between the teeth and basal bone by Howes'method, and to investigate the clinical value of this method in orthodontic diagnoses and treatment. 目的:本研究采用Howes法评估牙弓骨量与牙量的协调性,探讨其在正畸临床诊断与矫治设计确定拔牙与非拔牙中的应用价值。
Objective The study is aimed to establish the normal range of teeth, dental arch, basal bone and Howes 'values of Han People in Yunnan and to investigate its relationship. 目的建立云南省汉族正常(牙合)人群的牙、牙弓、基骨和Howes值的范围,探讨它们的内在联系。
Method 18 patients with moderate dental crowding were treated by rapid maxillary expansion and straight-wire appliance, the changes of width of dental arch and basal bone were measured before and after orthodontic treatment. 方法对18例恒牙早期牙列中度拥挤病例以上颌快速扩弓和直丝弓矫治器进行联合治疗,通过对矫治前后牙牙合石膏模型的测量比较,观察牙弓、基骨宽度的变化。
The modification of the dental length and arch width was accompanied with the changes in basal bone. 牙弓长度和宽度的改变同时可引起基骨的改变。
Upper and lower teeth could inclinate towards the direction for better interarch coordination, as the same time, coordination between dental arch and the corresponding basal bone arch was reduced. 骨性Ⅲ类错拾上下颌牙齿都向能够使上下颌牙弓协调的方向代偿性倾斜,同时牙弓与其对应基骨弓之间的协调性降低。
