摘　　要：目的比较硅橡胶间接法与嵌体蜡直接法制取铸造桩核的密合度。方法选择2009年1月1日—2013年12月31日期间于该科行金属桩核冠修复的患者共423例,患牙共计485颗。随机分为实验组(硅橡胶间接法制作铸造桩核)、对照组(常规嵌体蜡直接法制作铸造桩核)。桩核制作铸造完成后,分别对两组的密合度进行比较。结果实验组前牙密合度良好率94.5%,后牙为93.5%,对照组前牙密合度良好率91.7%,后牙为62.6%,实验组后牙与对照组后牙的密合度差异具有统计学意义(P<0.05)。结论使用硅橡胶印模材料,采用间接法制作的后牙铸造桩核,其密合度高于常规使用嵌体蜡直接法制作的铸造桩核密合度。Objective To compare the different marginal adaptation of casting post-core made by the direct method of inlay wax and by the indirect method of silicone rubber.Methods Took 423 cases of out-patients from Jan 1, 2009 to Dec 31, 2013 in the dental department of Guizhou provincial people＇ s hospital for example. A total of 485 teeth were randomly divided into experimental group （indirect method of silicone rubber tube） and control group （direct method of inlay wax）, and dentist took the two methods to produce the post-core. Then compare the marginal adaptation of casting post-core between the two groups.Results The percentage of fine marginal adaptation of anterior teeth and back teeth in experimental group is 94.5%, 93.5% respectively. The percentage of fine marginal adaptation of anterior teeth and back teeth in control group is 91.7%, 62.6% respectively.Conclusion The percentage of fine marginal adaptation of back teeth in experimental group is higher than that in the control group.
