目的:研究预成纤维桩和可塑纤维桩修复残根残冠的临床效果,并评估患者的咀嚼功能,为改善患者预后提供临床依据。方法:选择2014年9月-2015年8月在本院诊治的残根残冠修复患者136例,161颗牙,随机分为对照组和观察组,两组各68例,对照组80颗牙,应用可塑纤维桩修复;观察组81颗牙,应用预成纤维桩修复。观察两组患牙临床疗效,并评估咀嚼功能,观察其不良反应。结果:观察组的临床治疗效果和松动度均好于对照组,差异具有统计学意义(t=8.30、8.21,P<0.05);观察组咬合力和咀嚼效率分别为(10.97±1.16)kg和(87.56±1.16)%,均高于对照组(9.38±1.04)kg和(83.38±1.04)%,差异具有统计学意义(t=9.16、9.70,P<0.05);观察组就诊次数为(2.31±0.38)次,低于对照组(3.63±0.42)次,差异具有统计学意义(t=8.29,P<0.05);两组患牙不良反应结果比较,差异无统计学意义(X~2=0.76,P>0.05)。结论:预成纤维桩用于残根残冠临床修复效果好,有利于恢复患牙的咀嚼功能,减少患者的复诊次数。
OBJECTIVE: To study the clinical effect of prefiber piles and plastic fiber posts in the repair of residual residual crowns, and to evaluate the masticatory function of patients and provide a clinical basis for improving the prognosis of patients. Methods: 136 patients with 161 teeth were selected from September 2014 to August 2015 in our hospital. Sixty-six teeth were randomly divided into control group and observation group, with 80 teeth in control group , Application of plastic fiber post repair; observation group of 81 teeth, the application of pre-fiber post repair. To observe the clinical efficacy of two groups of teeth, and evaluate the masticatory function, observe the adverse reactions. Results: The clinical curative effect and loosening degree in the observation group were better than those in the control group (t = 8.30,8.21, P <0.05). The bite force and mastication efficiency in the observation group were (10.97 ± 1.16) kg and (87.56 ± 1.16)%, which were higher than that of the control group (9.38 ± 1.04) kg and (83.38 ± 1.04)% respectively, with statistical significance (t = 9.16,9.70, P <0.05) ± 0.38), lower than the control group (3.63 ± 0.42) times, the difference was statistically significant (t = 8.29, P <0.05); There was no significant difference in adverse reactions between the two groups (X ~ 2 = 0.76, P> 0.05). Conclusion: The prefabricated fiber post used in the residual root remnant crown clinical repair effect is good to restore the chewing function of the affected teeth and reduce the number of patients referral.
