目的:探究舌侧集中(牙合)型全口义齿修复对老年无牙颌患者颞下颌关节紊乱病的影响。方法:择取宁波大学医学院附属医院2012年6月至2014年9月收治的老年无牙颌伴颞下颌关节紊乱病患者进行抽样,选取66例患者随机分成两组,对照组推行解剖牙合型全口义齿修复治疗,实验组实施舌侧集中(牙合)型全口义齿修复治疗,对比两组临床治疗效果。结果:1功能障碍指数比较:修复后3个月,实验组功能障碍指数低于对照组(P<0.05),但修复后0~3个月、0~6个月下降值均高于对照组(P<0.05);2颞下颌关节指数比较:实验组修复后0~3个月与0~6个月颞下颌关节指数下降值明显高于对照组(P<0.05)。结论:舌侧集中(牙合)型全口义齿修复对改善老年无牙颌颞下颌关节紊乱病患者预后具有十分重要的应用意义,临床上应引起足够重视。
Objective: To investigate the effect of lingual centralization (occlusal) complete denture restoration on temporomandibular joint disorder in elderly patients with edentulous jaws. Methods: The elderly patients with edentulous jaw and temporomandibular disorder who were admitted to Affiliated Hospital of Ningbo University School of Medicine from June 2012 to September 2014 were selected for sampling. Sixty-six patients were randomly divided into two groups. The control group received anatomical occlusion Type complete denture repair treatment, the experimental group implementation of lingual focus (occlusal) complete denture repair treatment, the two groups compared the clinical effect. Results: 1 Comparison of dysfunction index: At 3 months after repair, the index of dysfunction in experimental group was lower than that in control group (P <0.05), but the decrease in 0 ~ 3 months and 0 ~ 6 months after repair was higher than that in control group (P <0.05) .2Comparison of temporomandibular joint index: The decrease of temporomandibular joint index in experimental group at 0 ~ 3 months and 0 ~ 6 months after repair was significantly higher than that in control group (P <0.05). Conclusion: It is of great significance to improve the prognosis of elderly patients with edentulous temporomandibular disorder. It is of great importance in clinical practice.
