目的探讨不同排龈方法对冠桥修复疗效的影响。方法 2009年10月至2011年10月期间,我院实施的40例冠桥修复患者,共60颗患牙,随机将其分为机械组(采用机械排龈法)和化学组(采用化学排龈法),给予相应治疗后,对其临床疗效进行比较。结果 30颗机械组患牙中,治疗后达到A级的有29颗,而化学组达到A级的仅有17颗。与化学组的治疗效果相比,机械组的治疗效果明显提高,P<0.05,差异具有统计学意义。结论化学排龈法进行冠桥修复的疗效显著,不良反应少,而且修复效果好。
Objective To investigate the effect of different methods of gingival retraction on the efficacy of crown bridge repair. Methods From October 2009 to October 2011, 40 patients with crown bridge repair in our hospital were divided into two groups: mechanical group (using mechanical retraction method) and chemical group (using chemical row Gingival method), given the appropriate treatment, the clinical efficacy of their comparison. Results In the 30 mechanized group of teeth, there were 29 A-class patients after treatment, and only 17 chemical-grade A patients. Compared with the treatment effect of the chemical group, the treatment effect of the mechanical group was significantly improved, P <0.05, the difference was statistically significant. Conclusions The chemical gingival retraction method for crown bridge repair has significant curative effect, less adverse reactions, and good repair effect.
