摘要:

背景:光固化复合树脂修复缺损牙冠,既能修复其应用功能又能修复其形态功能。
目的:探讨光固化复合树脂修复牙冠缺损的治疗效果。
方法:应用文献检索的方法获取光固化复合树脂修复牙冠缺损的相关研究文献,对符合研究标准的文献进行深入的数据分析。并将解放军沈阳军区总医院临床应用光固化复合树脂修复牙冠缺损患者的随访治疗效果与文献研究中的结果进行比较,以明确光固化复合树脂修复牙冠缺损应用的可行性。
结果与结论:文献数据研究中,光固化复合树脂材料修复牙冠缺损的成功率达90%以上。临床治疗随访的12例患者修复后检查患牙修复的光固树脂冠稳固,修复的外观与邻牙对侧同名牙对称,有正常的咬颌关系。随访观察修复后的19颗患牙,稳固无松动,无脱落,咬颌关系正常,无叩痛,X射线片显示根尖无阴影。而光照对双固化树脂修复牙冠缺损影响的研究中显示,光固化的效果仅限于根上段和根中段,不能影响根尖段的固化效果,且能够获得较好的治疗效果。

Abstract:

BACKGROUND: Light-cured composite resin is used for dental crown defective repair in terms of both function and morphology.
OBJECTIVE: To investigate the therapeutic effects of light-cured composite resins on crown defects.
METHODS: Relevant literatures concerning light-cured composite resins for repair of crown defects were retrieved. Literatures which met the study standard were deeply analyzed. Meanwhile, follow-up results and literature results were compared for patients receiving light-cured composite resins for repair of crown defects to identify the feasibility of light-cured composite resins for repair of crown defects.
RESULTS AND CONCLUSION: Based on the included data, the successful rate of light-cured composite resins for repair of crown defects was over 90%. Clinical follow-up of 12 patients undergoing light-cured composite resin showed that the repaired crowns were stable and fixed, and exhibited a symmetrical appearance with the contralateral namesake tooth of the adjacent tooth, and there was a normal bite relationship. During the follow-up study, 19 teeth repaired from 12 patients had no loosing, no shedding, no percussion pain and normal bite relationship. X-ray films showed no apical shadows. Light-cured effects were limited to the upper and middle parts but not to the apical part. Therefore, a better therapeutic effect can be obtained.
