目的探讨氧化锆全瓷对牙冠延长手术后患者牙周状况的影响。方法选取2014年4月-2015年4月在医院进行冠修复患者120例,患者均行牙冠延长术,随机分为观察组(牙冠延长术后给予氧化锆全瓷冠修复)和对照组(牙冠延长术后给予钴铬合金烤瓷冠修复),每组60例。观察2组术后牙周状况及患者对修复效果的满意度。结果观察组轻度病损率低于对照组,牙周正常率显著高于对照组,术后康复时间、术后戴临时修复体时间均显著短于对照组,对修复效果满意度高于对照组,差异均有统计学意义(P<0.05)。结论牙冠延长手术后采用氧化锆全瓷修复治疗周期短,对牙周组织损伤小,患者满意度高,具有推广价值。
Objective To investigate the effect of zirconia porcelain on the periodontal status of patients after crown extension surgery. Methods From April 2014 to April 2015, 120 patients with crown restoration in our hospital were enrolled in this study. All patients underwent coronary crown extension and were randomly divided into observation group (zirconium ceramic crowns restored after crown extension) and control group (Crown extended cobalt-chromium alloy porcelain crown repair), 60 cases in each group. The postoperative periodontal status and patient satisfaction with the repair effect were observed. Results The mild lesions in the observation group were lower than those in the control group, and the normal periodontal rate in the observation group was significantly higher than that in the control group. The postoperative rehabilitation time and the postoperative temporary restoration time were significantly shorter than those in the control group, Group, the difference was statistically significant (P <0.05). CONCLUSIONS: Zirconia all-ceramic restoration after crown extension surgery has a short treatment cycle, small damage to periodontal tissues and high patient satisfaction, which has the promotion value.
