Methods The three-dimensional model ( 3-DFEM) of TMJ including mandible of edentulous jaw patient was constructed by helix-CT scanned transverse sections. 探讨戴用全口义齿无牙颌患者在牙尖交错位紧咬牙时颞下颌关节髁状突的应力分布特征。
Objective: To evaluate the periodontitis, dentition defect and edentulous jaw status of old patients with Diabetes Mellitus in Weihui. 目的:了解分析卫辉市部分老年糖尿病患者牙周炎、牙列缺损和牙列缺失情况。
A pilot study on jaw relation of edentulous patients with digital cephalometric system DETERMINATION OF VERTICAL DIMENSION OF EDENTULOUS JAW WITH CEPHALOMETRIC METHOD 应用数字化X线头影测量法对无牙颌颌位关系的初步研究
Objective To find the position change of the mandibulae and condyle during the different vertical distance of edentulous jaw of patients. 目的探讨无牙颌患者不同垂直距离时下颌骨及髁状突的位置变化。
Results Data of edentulous jaw models were obtained. 结果对无牙颌模型逐层切削后获得完整无牙颌数字模型;
Influence of stress distribution on condyle anterior incline during different vertical distances of edentulous jaw 无牙颌患者垂直距离对髁状突前斜面应力分布的影响
Results: Data of upper edentulous jaw models and a palatal metal plate of upper complete denture were obtained. 结果:获得无牙颌三维数据及上颌金属基托的数据文件。
The horseshoes shape mould was used to simulate edentulous jaw's dental alveoli crista, which could partly directly reflect the transformation tendency of dentures, and on which their line shrink and volume change level could be examined and calculated. 为了更接近临床实际,运用马蹄形模具,模拟无牙颌的牙槽嵴,可以部分直观地反映义齿变形的趋势,同时也可以推测其线形收缩及体积变化的程度;
Complete denture restoration on edentulous jaw with flabby alveolar ridge 松软牙槽嵴无牙颌的全口义齿修复
Methods Standard edentulous jaw models were measured with a improved measurement system by cutting and scanning layer-by-layer, and the 3D shape of the models was reconstructed by image processing with specialty software. 方法采用改进的层析测量系统对无牙颌模型逐层切削,进行数据运算,重建无牙颌数字模型。
Clinical Apply the Implant Overdentures for Edentulous Jaw 全颌种植覆盖义齿修复的临床应用初探
Objective: Edentulous jaw is a common condition encountered in clinical practice. Complete denture can partly recover patients 'masticatory function and improve their facial contour. 目的:牙列缺失是临床上常遇见的问题,总义齿修复可以在一定程度上恢复患者咀嚼功能,改善面部外形。
