目的 :分析金属烤瓷冠与全瓷冠修复体牙齿修复效果及对牙周组织的影响。方法选择2013年9月到2014年11月本院收治的77例牙齿冠桥修复的患者(130颗牙),随机分为对照组(33例,53颗牙)和观察组(34例,67颗牙),对照组采用金属烤瓷冠进行修复,观察组采用全瓷冠进行修复,对两组患者的修复结果进行观察,比较两组患者修复前后基牙牙龈色泽、牙龈指数、菌斑指数等情况。结果 :修复前后观察组基牙牙龈色泽、牙龈指数、菌斑指数均优于对照组,差异均具有统计学意义(P<0.05)。结论全瓷冠用于牙齿修复效果优于金属烤瓷冠,且对牙周组织影响较小。
OBJECTIVE: To analyze the effect of restoration on periodontal ligament and porcelain crowns with porcelain crowns and all-ceramic crowns. Methods Seventy-seven patients with crown-bridge restoration (130 teeth) treated in our hospital from September 2013 to November 2014 were randomly divided into control group (33 cases, 53 teeth) and observation group (34 cases, 67 cases) Teeth). The control group was repaired with metal porcelain crowns. The observation group was repaired with all-ceramic crowns. The repair results of the two groups were observed. The gingival color, gingival index, plaque index And so on. Results: The gingival color, gingival index and plaque index of the abutments in the observation group before and after the repair were better than those in the control group. The differences were statistically significant (P <0.05). Conclusion All-ceramic crowns are superior to metallic crowns for dental restoration and have less effect on periodontal tissues.
