两种修复牙弓双端游离缺失方法对照探究【摘要】目的 比较弹性树脂与铸造支架联合义齿修复、快套式精密附着体修复双端游离缺失的疗效。 方法63例牙弓双端游离缺失患者随机分成32例采用弹性树脂与铸造支架联合义齿修复为对照组，31例采用快套式精密附着体修复为观察组。通过外观美观、舒适程度、咀嚼功能、食物嵌塞、基牙情况、固位力、黏膜情况的优、良、差判断两种方法的治疗效果。 结果 弹性树脂与铸造支架联合义齿修复与快套式精密附着体修复双端游离缺失的治疗效果比较结果表明，外观美观、舒适程度、咀嚼功能、食物嵌塞两组无统计学差异（P＞0.05）。牙情况、固位力、黏膜情况，快套式精密附着体修复明显比弹性树脂与铸造支架联合义齿修复好（P＜0.05）。结论 弹性树脂与铸造支架联合义齿修复和快套式精密附着体修复对双端游离缺失均有一定的疗效，但快套式精密附着体修复在牙情况、固位力、黏膜情况方面比弹性树脂与铸造支架联合义齿修复好。 【关键词】弹性树脂与铸造支架联合义齿修复 快套式精密附着体修复 牙弓双端游离缺失 中图分类号：R783文献标识码：A文章编号：1005-0515（2010）12-041-02 ControlStudy of Double-end Edentulous Arch Repair LU Chuan （Department of Stomatology, Third Hospital of Nanchang City, Jiangxi Nanchang 330009） 【Abstract】 Objective To comparerestore the double-end edentulous effect ofthe elastic resin and casting stent and denture repair, fast precision attachment prostheses . Methods 63 patients with double-end edentulous arch were randomly divided into 32 cases with elastic resin and casting stent prosthesis as the control group, 31 cases with precision attachment of quick restoration as the observation group. The therapeutic effectof two methods were determined byy the excellent, good, bad of appearance, comfort, chewing function, food impaction, abutment conditions, retention, mucous membrane conditions. Results The effects of two methods shows that there werethe no significant difference in aesthetic appearance, comfort, chewing function, food impaction (P 0.05.) The fast precision attachment prostheses were significantly higher than elastic resin prosthesis with stent and denture with a good cast in dental conditions, retention, mucous membrane condition, fast precision attachment (P 1.3 疗效判断标准 优：外观满意；主观感觉舒适；能正常行使咀嚼功能；义齿边缘密合，义齿与基牙和口腔黏膜紧密接触，无食物嵌塞；基牙不疼痛；义齿固位好，稳固，无软组织压痛和炎症。良：外观基本满意；舒适感一般，有异物感；咀嚼基本恢复正常；义齿边缘不密合，轻度食物嵌塞；基牙出现疼痛和炎症，经治疗后缓解；固位一般，软组织疼痛或炎症，经治疗缓解。差：有以下任何一种情况即为差：外观效果差；舒适感差，异物感严重；咀嚼功能差；食物嵌塞严重；诱发基牙病变；无法恢复的固位差，黏膜疼痛，经复诊多次仍无法解决需拆除或改作其它修复方式。 1.4 统计方法采用软件包计算，2×n格表X2检验 2 结果 两种修复方法临床效果 比较结果表明，外观美观、舒适程度、咀嚼功能、食物
