全冠修复联合牙合贴面修复治疗牙体缺损疗效及对抗折强度影响

Effect of Full Crown Restoration Combined with Occlusal Veneer in the Treatment of Tooth Defect and Its Effect on Fracture Strength

目的:探讨全冠修复联合牙合贴面修复治疗牙体缺损疗效及对抗折强度影响。方法:选取我院口腔科2018年6月至2020年6月收治的牙体缺损患者80例,将其随机分为研究组和对照组,每组患者40例,研究组应用全冠修复联合牙合贴面修复治疗,对照组只应用全冠修复治疗,对比两组的治疗效果、美观、固定及咀嚼功能、折裂载荷值以及不良反应情况。结果:研究组的治疗总有效率显著高于对照组(95.05%vs.80.0%,P<0.05);研究组的美观、固定及咀嚼功能明显高于对照组(P<0.05);研究组的折裂载荷值明显好于对照组(P<0.05);研究组发生不良反应的概率明显低于对照组(5.0%vs. 22.5%,P<0.05)。结论:利用全冠修复联合牙合贴面修复治疗牙体缺损效果优于单纯全冠修复,抗折强度较高,美观、固定及咀嚼功能好,安全性好,值得临床应用推广。

Objective: To investigate the effect of full crown restoration combined with occlusal veneer in the treatment of tooth defect and the influence of fracture strength. Methods: A total of 80 patients with tooth defect, who were treated in Second Affiliated Hospital of Nanjing University of Chinese Medicine from June 2018 to June 2020, were selected and randomly divided into study group(n=40) and control group(n=40). The study group was treated with full crown restoration combined with occlusal veneer restoration,while the control group was only treated with full crown restoration. The treatment effect, aesthetics, fixation and chewing function,fracture load value and adverse reactions were compared between the two groups. Results: The total effective rate in the study group was significantly higher than that in the control group(95.05 % vs. 80.0 %, P<0.05). The beauty, fixation and chewing function of the study group were significantly higher than those of the control group(P<0.05). The fracture load value of the study group was much better than that of the control group(P<0.05). The probability of adverse reactions in the study group was significantly lower than that in the control group(5.0 % vs. 22.5 %, P<0.05). Conclusion: The effect of full crown restoration combined with occlusal veneer restoration in the treatment of tooth defect is better than that of simple full crown restoration, with high fracture strength, good aesthetics, good fixation and chewing function, and good safety, which is worthy of clinical application and promotion.
