摘  要:目的 :分析和比较伴有及不伴有颞下颌关节损伤的慢性类风湿关节炎病人的下颌骨形态和位置。方法 :研究组选择 8名患有慢性类风湿关节炎伴有颞下颌关节损伤的生长期女孩。选择三个生长阶段 ,第一阶段平均 10岁 ,第二阶段平均 12岁 ,第三阶段平均 14岁。测量生长高峰期前 ,高峰期 ,高峰期后的头颅侧位片 ,分析下颌骨及下颌牙齿的变化。对照组选择 8名患有慢性类风湿关节炎不伴有颞下颌关节损伤的相同时期女孩。结果 :研究组下颌骨发育障碍 ,围绕磨牙区向后旋转后缩 ,下颌支变短 ,下颌角前凹加深 ,下颌骨前部增高 ,呈高角形 ,下切牙前突。结论 :生长期患有慢性类风湿关节炎伴有颞下颌关节损伤的病人下颌骨发育障碍 。Objective:To analyse and compare the mandibular morphology and position of patients with juvenile rheumtoid arthritis(JCA) with and without temporomandibular joints (TMJ) involvement.Methods:Study group included 8 growth period girls with JCA and TMJ involvement,8 the same period girls with JCA and without TMJ involvement as control group.In each subject,3 stages were chosen,befor,during and after growth peak.The first stage was 10 years old,the second stage was 12 years old,the third stage was 14 years old.The mandibular morphology and position were analysed with the aid of lateral cephalometry.Results:This longitudinal study revealed obvious mandibular growth disturbances in the study group.The mandibule became more retruded by rotating posteriorly around central molar areas,the height of front mandibule was longer.Conclusion:The mandibular growth disturbance showed in study group and would be deteriorated if the treatment was not performed,therefore the early orthodontic treatment was very important.
