摘要
目的:探讨Dyract复合体能否替代夹层技术修复楔状缺损。方法:在同一体上选择条件基本相同的楔状缺损患牙236颗,分别采用Dyract和夹层技术修复,随访观察12-18个月,并对其疗效进行比较。结果:Dyract组、夹层技术组分别有3、7颗修复体脱落,其余牙面均光滑,无缺损;两组均无继发龋及牙髓病变发生;Dyract组失败率为2.54%,夹层技术组失败率为5.93%。结论:Dyract在修复楔状缺损方面可替代夹层技术。
Objective: To study whether Dyract can be used to take the place of Sandwich technique for restoring wedge shaped defect in teeth. Methods: Dyract and Sandwich technique have been applied to restore wedge - shaped defect in teeth in the same body and with similar conditions. 236 teeth are treated. Follow - up studied are made for 12 ~ 18months, and their efficiencies are compared. Results: The prosthetic substance scaled off in three teeth (2. 54% ) in the Dyract group and in 7 teeth (5.93%) in Sandwich group,respectively. All the other teeth have a smooth surface and have no defect. No secondary caries or pulp lesions occurs. The success rate in Dyract group is 97.46%. There is no significant difference between the two groups. Conclusion: Dyract can be used to take the place of Sandwich technique for restoring wedge - shaped tooth defeit.
