目的:探讨光固化树脂充填楔状缺损的临床疗效。方法:对本院200例楔状缺损进行自酸蚀粘接及光固化树脂充填,随访两年观察其疗效。结果:充填后1年脱落6例,出现牙齿敏感8例;2年后脱落8例,出现牙齿敏感症11例。结论:光固化树脂是目前充填楔状缺损比较理想的修复材料,但同时要注意洞形的制备,防止出现脱落;关于材料的性能问题,有待于进一步改进和提高。
Objective: To investigate the clinical efficacy of photocurable resin filling wedge-shaped defect. Methods: 200 cases of wedge-shaped defects in our hospital self-etching adhesive and light-cured resin filling, followed up for two years to observe its efficacy. Results: Six cases were shedding one year after filling, 8 cases were tooth sensitivity, 8 cases were shedding after 2 years and 11 cases were tooth sensitivity. CONCLUSION: Photocurable resin is an ideal repair material for filling wedge-shaped defects. At the same time, it is necessary to pay attention to the preparation of the cavity to prevent the occurrence of shedding. The performance of the material needs to be further improved and improved.
