目的:对比分析全瓷冠与金属烤瓷冠在牙齿修复中的效果。方法:选择2013年9月至2014年11月该院收治的72例牙齿修复患者对研究对象,在患者及其家属知情同意的情况下随机分为观察组和对照组各36例。观察组给予全瓷冠修复,对照组给予金属烤瓷冠修复,随访观察1年,观察比较两组患者颈缘黑线、牙龈指数、烤瓷冠桥裂纹及折痕情况。结果:观察组患者中颈缘黑线发生率为0%明显低于对照组69.4%,其牙龈指数情况明显优于对照组(P<0.05);对照组患者烤瓷冠桥裂纹及折痕发生率为2.8%明显低于观察组(16.7%,P<0.05)。结论:采用全冠词修复义齿具有外表美观、对牙周组织伤害小的优势,但其硬度小,抗裂抗折断性能不及金属烤瓷冠。因此,在临床上要结合患者具体修复情况和患者意愿来选择义齿材料进行修复。
Objective: To compare and analyze the effect of all-ceramic crowns and metal porcelain crowns in dental restoration. Methods: From September 2013 to November 2014, 72 patients with dental restoration in our hospital were selected and randomly divided into observation group (36 cases) and control group (36 cases) with the informed consent of patients and their relatives. The observation group was given the all-ceramic crown repair. The control group was given the porcelain-fused-to-metal crown for repair. The patients were followed up for 1 year. The black margin, gingival index, crevices and creases of the porcelain crown and bridge in the two groups were observed and compared. Results: In the observation group, the incidence of black line on the cervical margin was 0%, which was significantly lower than that of the control group (69.4%). The gingival index of the observation group was significantly better than that of the control group (P <0.05) The rate of 2.8% was significantly lower than that of the observation group (16.7%, P <0.05). CONCLUSION: The whole article prosthesis has the advantages of beautiful appearance and less damage to the periodontal tissue. However, the hardness of the denture is less than that of the metal porcelain crowns. Therefore, in the clinical practice to be combined with the patient’s specific repair and the wishes of patients to choose denture materials for repair.
