目的探讨前牙牙冠延长术后采用氧化锆全瓷修复行冠修复对患者牙周状况的影响。方法 114例(126颗患牙)行前牙牙冠延长术患者,按随机数字表法分为实验组(57例,62颗患牙)与对照组(57例,64颗患牙)。实验组采用氧化锆全瓷修复行冠修复,对照组采用金属烤瓷修复行冠修复。对比两组临床疗效、康复时间、修复体佩戴时间及术后炎症发生情况等。结果实验组牙周正常率为88.7%(55/62),高于对照组的70.3%(45/64),差异具有统计学意义(P<0.05);实验组康复时间、修复体佩戴时间均短于对照组,差异具有统计学意义(P<0.05);实验组炎症发生率为4.8%(3/62),低于对照组的18.8%(12/64),差异具有统计学意义(P<0.05)。结论前牙牙冠延长术后采用氧化锆全瓷修复材料进行冠修复,能有效改善患者牙周组织健康,且能减少炎症的发生,促使患者尽快康复,值得进行深入研究和推广。
Objective To investigate the effect of zirconia restoration on the periodontal status of patients with crown restoration after crown anterior extension. Methods One hundred and fourteen patients (126 teeth) underwent crown anterior extension. The patients were divided into experimental group (57 cases, 62 teeth) and control group (57 cases, 64 teeth) by random number table. The experimental group was treated with zirconia all-ceramic restoration and the control group was repaired by metal porcelain restoration. The clinical efficacy, recovery time, wearing time of prosthesis and postoperative inflammation were compared between the two groups. Results The normal periodontal rate in the experimental group was 88.7% (55/62), which was higher than that in the control group (70.3%, 45/64), the difference was statistically significant (P <0.05). The recovery time, wearing time The difference was statistically significant (P <0.05). The incidence of inflammation in experimental group was 4.8% (3/62), which was lower than that in control group (18.8%, 12/64) (P <0.05). Conclusion The use of zirconia all-ceramic restoration material for the crown restoration after the crown anterior extension can effectively improve the periodontal tissue health of patients and reduce the occurrence of inflammation, which prompts the patients to recover as soon as possible and deserves further study and promotion.
