目的:探讨临时树脂冠在后牙冠纵折及隐裂治疗中的辅助作用。方法:后牙冠纵折或隐裂时制作树脂临时冠保护患牙,使其免受治疗中的再次创伤,观察临时冠辅助治疗的临床效果。结果:治疗后随访3年,未出现急慢性根尖周炎症状及患牙松动、脱落即视为成功。对照组共治疗21颗患牙,其中3年内发生牙冠裂开或冠折8例,发生慢性尖周炎并龈瘘2例,3年治疗成功率52.4%。临时树脂冠保护治疗共55颗;其中3年内发生根尖周炎并龈瘘4例,未及时复诊致树脂临时全冠折断后失败1例,3年治疗成功率90.9%。结论:后牙早期冠纵折及隐裂治疗过程中使用树脂临时树脂冠保护换患牙,防止再次创伤,可使临床治愈率明显提高。
Objective: To explore the auxiliary role of temporary resin crowns in the treatment of posterior crown longitudinal occlusion and occlusion. Methods: The temporary crown of the posterior crowns was made to protect the teeth during the longitudinal or occultation, so as to protect the teeth from further trauma in the treatment and to observe the clinical effect of the temporary crown adjuvant therapy. Results: After 3 years of follow-up, there were no symptoms of acute and chronic periapical periodontitis and loosening of the affected teeth, which was regarded as success. A total of 21 teeth were treated in the control group. Among them, there were 8 cases of crown fractures or crown fractures in 3 years, 2 cases of chronic periapical inflammation and gingival fistula, and 3 years of treatment success rate of 52.4%. Temporary resin crown protection treatment a total of 55; of which 3 cases of periapical periodontitis and gingival fistula in 4 cases, did not promptly repaired the temporary crown after the failure of one case of failure, 3-year treatment success rate of 90.9%. Conclusion: In the process of early posterior longitudinal crease and occlusion of the posterior teeth, the resin temporary resin crown is used to protect the affected teeth from replacement and prevent further trauma, which can significantly improve the clinical cure rate.
