摘要 目的探讨桩核冠修复严重牙体缺损的残冠残根时,不同方法制取桩核熔模的特点及临床效果。方法采用常规嵌体蜡法、自凝塑料法和硅橡胶印模法分别对96颗、102颗和130颗已做过完善根管治疗的患牙进行铸造桩核熔模的制作并完成冠修复,比较其临床效果。结果常规嵌体蜡法、自凝塑料法和硅橡胶印模法三者制取的铸造桩核熔模成功率分别为80.21%,95.10%和96.92%,3种方法成功率比较有显著性差异(P均<0.05),自凝塑料法和硅橡胶印模法优于常规嵌体蜡法(P均<0.05),自凝塑料法和硅橡胶印模法比较无显著性差异(P均>0.05)。结论硅橡胶印模法制取铸造桩核熔模简便、精确、无毒副作用、成功率高,适宜临床广泛推广。
