摘　　要：目的:比较观察根纵裂下颌磨牙半切术后不同修复方式的远期临床疗效。方法:按纳入标准治疗发生根纵裂的下颌磨牙112个,对拟保留的牙根经完善的根管治疗术后,行半切除术。分别采用单端固定桥和双端固定桥修复。术后12、24、36个月随访,评价其临床疗效。结果:术后12个月时双端固定桥和单端固定桥修复成功分别为100%和95.83%(P>0.05);术后24个月时分别为89.66%和71.74%(P<0.05);术后36个月时,成功率分别为88.37和35.48%(P<0.05)。结论::发生根纵裂的下颌磨牙行半切术后,双端固定桥修复能够取得较好的远期疗效。AIM ： To compare the long-term clinical effects of two prosthodontic designs for mandibular mo- lars after hemisection. METHODS： 112 mandibular molars with vertical root fracture were treated. Hemisection was performd and root canal therapy was conducted on the roots to be retained. Rigid fixed bridge （ RFB, n = 60） and canti- lever fixed bridge（ CFB, n = 48） were respectively allowed after the surgery and the clinical effects were evaluated after 12 m, 24 m and 36 m respectively. RESULTS： 12 months after tretment success rates of RFB and CFB were 100% and 95.83% （P 〉 0.05 ）, 24 months after tretment 89.66% and 71.74% （ P 〈 0.05 ）, 36 months after tretment 88.37% and 35.48% （ P 〈 0.05 ） respectively. CONCLUSION ： After hemisection therapy on the mandibular molars with vertical root fracture rigid fixed bridge can achieve better long-term efficacy than cantilever fixed bridge.
