目的 :研究青少年类风湿性关节炎侵及颞颌关节对患者牙合关系的影响。方法 :研究组 8名患有青少年类风湿性关节炎侵及颞下颌关节的病例 ,均为女性 ,分为三个阶段 ,第 1阶段平均 10岁 ,第 2阶段平均 12岁 ,第3阶段平均 14岁。对照组 8名患有青少年类风湿性关节炎未侵及颞颌关节的病例 ,相同的性别 ,年龄。对三个阶段的牙牙合模型进行测量 ,分析牙牙合关系的发展变化。用t检验检查两组间的差异。结果 :研究组以AngleII类错牙合为主 ,上下前牙拥挤 ,前牙开牙合 ,上颌前突明显高于对照组。使用功能矫正器治疗 ,拥挤可以解除 ,前牙开牙合 ,上颌前突 ,磨牙II类错牙合得以缓解。结论 :类风湿性关节炎侵及颞颌关节将导致患儿错牙合畸形。
Objective: To study the influence of adolescent rheumatoid arthritis on the occlusion relationship of temporomandibular joint. Methods: The study group of 8 patients with adolescent rheumatoid arthritis invading the temporomandibular joint cases were female, divided into three stages, the first stage of an average of 10 years, the second stage of an average of 12 years, the third stage of the average 14 years old. The control group of 8 patients with juvenile rheumatoid arthritis did not invade the temporomandibular joint cases, the same gender, age. The three stages of the occlusal model were measured to analyze the development of the occlusal relationship. T test to check the difference between the two groups. Results: The study group was mainly Angle II malocclusion. The upper and lower anterior crowded crowns, anterior teeth open occlusal and maxillary protraction were significantly higher than the control group. The use of functional orthosis treatment, crowding can be relieved, the anterior teeth open crooks, maxillary protrusion, molars Class II malocclusion can be alleviated. Conclusion: The invasion of temporomandibular joint by rheumatoid arthritis will lead to malocclusion in children.
