| 摘要 目的：摘要 目的：比较氧化锆全瓷修复与金属烤瓷修复在前牙牙冠延长术后冠修复中的应用效果及安全性。方法：选取2016年7月~2018年7月我院收治的择期行前牙牙冠延长术后冠修复的患者80例(共97颗上颌牙)，采用随机数字表法将患者分为两组，对照组40例(48颗患牙)采用金属烤瓷修复，观察组40例(49颗患牙)采用氧化锆全瓷修复。比较两组患者的牙体修复效果和牙周修复效果，治疗前后龈沟出血指数(sulcus bleeding index，SBI)、松动度(movable degree，MD)和菌斑指数(plaque index，PI)的变化以及不良反应的发生情况。结果：治疗后，观察组临床治疗总有效率显著高于对照组(87.76% vs. 70.83%，P＜0.05)；观察组患者的边缘密合度、牙体折损、牙体颜色和牙龈健康状况均显著优于对照组(P＜0.05)；两组患者治疗后的SBI、MD和PI均较治疗前显著下降，且观察组以上指标显著低于对照组(P＜0.05)。观察组患者不良反应发生率显著低于对照组(P＜0.05)。结论：氧化锆全瓷修复用于前牙牙冠延长术后冠修复的临床效果显著优于金属烤瓷修复，且安全性更高。 |

| ABSTRACT Objective: To compare the effect and safety of zirconia all-ceramic restoration with metal ceramic restoration on the crown restoration of anterior teeth after lengthening. Methods: 80 patients (97 maxillary teeth in total) who underwent crown restoration after lengthening of anterior teeth were selected in our hospital from July 2016 to July 2018. The patients were divided into two groups by the random number table method. 40 patients (48 affected teeth) in the control group were repaired with metal porcelain, and 40 patients (49 affected teeth) in the observation group were repaired with zirconia porcelain.The results of dental restoration and periodontal restoration, the changes of sulcus bleeding index (SBI), mobility degree (MD) and plaque index (PI) as well as the occurrence of adverse reactions were compared between the two groups before and after treatment. Results: After treatment, the total effective rate in the observation group was significantly higher than that in the control group (87.76% vs. 70.83%, P <0.05). The patients in the observation group were significantly better than those in the control group in terms of marginal closeness, tooth breakage, tooth color and gingival health status (P <0.05). The SBI, MD and PI in the observation group was significantly lower than those of the control group (P <0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group (P <0.05). Conclusion: Zirconium all-ceramic restoration for anterior crown extension is significantly better than metal-ceramic restoration, which can significantly improve the patients' SBI, MD and PI with higher safety. |
