摘　　要：目的研究栓体栓道式附着体在下颌倾斜基牙固定修复中的临床应用效果。方法对20例下颌第二前磨牙或第一磨牙缺失,两端基牙牙体牙髓牙周组织正常,且向缺牙区倾斜,通过常规的牙体预备两基牙不能获得共同就位道的病例,利用栓体栓道式附着体进行固定修复。结果经过3年的随访观察,有2例患者固定桥栓体栓道连接部位出现松动,但修复体的咀嚼功能良好,无一例患者出现固位体的松动,基牙无松动,无牙髓牙周以及根尖周炎症。结论栓体栓道式附着体在下颌倾斜基牙固定修复中的应用效果较好。Objective To investigate the clinical result of key-way attachment in fixed restoration to tilted mandibular abutments. Methods We made fixed restoration with key-way attachment in 20 cases in which the second premolar or the first molar in mandible was lost,adjacent teeth were tilted,and the same path of insertion couldn＇t be found after common teeth preparations. Results After 3 years＇ observation, looseness between the two parts of attachment was found in two cases. But 20 cases had good chewing function. Looseness of crown,abutment looseness,gingivitis,pulpitis and apicitis were not found. Conclusions The fixed restoration with key- way attachment is a good restoration for tilted abutments.
