摘要
目的 探讨四种方法制取铸造桩核的临床效果。方法 对 4 2 7颗经完善根管治疗的患牙 ,其中 98颗、118颗、10 1颗、110颗依次分别用自凝树脂、嵌体蜡、红色打样膏、琼脂印模材制取桩核 ,并随访观察 1～ 3年。结果 4 10颗桩核固位良好 ,边缘密合 ,未发生继发龋及牙周组织病变。自凝树脂、嵌体蜡、红色打样膏、琼脂印模材制取桩核的成功率分别为 93 87%、94 91%、95 0 5 %、94 5 4 %。四组的临床效果无显著性差异 (P >0 .0 5 )。结论 四种方法都能取得良好的疗效 ,但临床必须注意各种方法的适应证选择。
Objective To investigate the clinical effect of four methods to get casting post cores. Methods A total of 427 residual roots and crowns, after the perfect root canal therapy, were restored by four different methods, including 98 with self curing resins,118 with inlay wax,101 with red impression compound and 110 with agar impression material. All patients were followed up 1～3 years. Results Four hundred and ten post cores had effective border position and retention. No periodontal diseases and secondary caries arose. The success rates of post cores of self curing resins, inlay wax, red impression compound and agar impression material were 93.87%, 94.91%, 95.05% and 94.54% respectively. There were no significant difference in short term results between four groups( P >0.05).
