摘要
目的:比较纤维主辅桩与铸造金属桩核在喇叭口状牙体缺损修复中的临床疗效。方法:选择2011年1月~2013年1月就诊的72例患者(98颗患牙),牙冠大面积缺损且根管呈喇叭口状,随机分为观察组与对照组两组,观察组患者52颗牙,对照组患者46颗牙,对照组患者患牙行铸造金属桩核修复,观察组患者的患牙行纤维主辅桩核修复。修复完成后随访24月以上,评价修复体完整性、桩核脱落、桩核折断、根折、冠边缘牙龈色泽、牙周及根尖周组织等。结果:修复2年后,观察组患者的患牙修复体完整性失败例数、桩核松动及根折数目低于对照组(P〈0.05),两组患者的患牙边缘适应性及继发性根尖周炎等方面差异无统计学意义(P〉0.05)。结论:对于临床喇叭口状残根残冠牙的修复,纤维主辅桩系统能更好地保护患牙牙根,是一种行之有效的修复方法。
Objective:To evaluate and compare the clinical effects between fiber post combined with accessory post and cast metal post in the restoration of trumpetshaped root canal defects. Methods: 72 patients (98 teeth) with massive dental defects and trumpet -shaped root canal from January 2011 to January 2013 were chosen and divided casually into control group (52 teeth) and observation group (46 teeth). The cases in the control group were treated with cast mental post crown restoration while the cases in the observation group were treated with the restoration of fi- ber post combined with accessory post. Afterwards patients were followed up for 24 months to evaluate the restoration completeness, post and core detachment and breaking, root fracture, crown margin color, periodontal and periapical tissues, etc. Results: The situation in the observation group was better than that in the control group 2 years after treatment in aspects of restoration completeness, post and core detachment and root fracture ( P 〈 0.05 ), but there was no statistical significance in marginal fit and secondary periapical periodontitis ( P 〉 0.05 ). Conclusions: Fiber post combined with accessory post is an effective method for the preservation of residual crown in the restoration of trumpet - shaped root canal defects.
