摘要
目的:探讨固位形在光固化复合树脂修复楔状缺损中的作用。方法:选择个体条件基本相同的楔状缺损患牙,以光固化复合树脂分别采用有固位形和无固位形2种修复方法修复,共46例120颗牙,随访观察8-24个月。结果:有固位形组的脱落率明显低于无固位形组,其他牙体损害、牙髓不良反应、边缘密合,无明显差异。结论:制备固位形,有助于增加光固化复合树脂修复楔状缺损的固位,有助于提高疗效。
Objective: To explore the effect of the retentive form in repairing wedge-shaped defect. Methods: To repair120 wedge-shaped defect in same conditions with the light-cured composite resin, two groups with retentive form andnon-retentive form. Results: The falling of non-retention-group exceeded the retention-group. The other targets have notsignificant difference. Conclusions: The retentive form helps to get better retention in restoring the wedge-shaped defectwith light-cured composite resin.
