摘　　要：背景:在近年来的牙列缺损临床修复中,常见的支架式可摘局部义齿材料主要有Vitallium 2000材料、钴铬合金材料及纯钛材料。目的:分析不同材料支架式可摘局部义齿修复牙列缺损的价值。方法:纳入牙列缺损患者90例,其中男45例,女45例,年龄20-57岁,均采用支架式可摘局部义齿进行修复,其中30例采用Vitallium 2000材料支架式可摘局部义齿,30例采用纯钛材料支架式可摘局部义齿,30例采用钴铬合金材料支架式可摘局部义齿。观察比较3组2年的义齿就位率、义齿性口炎、基牙牙周病和继发龋发生率及患者主观自我评价满意度等情况。结果与结论:Vitallium 2000材料组义齿就位率明显高于纯钛材料组和钴铬合金材料组(P<0.05),义齿性口炎发生率明显低于纯钛材料组和钴铬合金材料组(P<0.05),基牙牙周病和继发龋发生率明显低于纯钛材料组和钴铬合金材料组(P<0.05),患者对于可摘局部义齿轻巧舒适度、美观度、咀嚼力、异味度的自我评价满意度均明显高于纯钛材料组和钴铬合金材料组(P<0.05)。表明Vitallium 2000支架式可摘局部义齿可更好地提高义齿就位率,降低义齿性口炎及基牙牙周病和继发龋的发生率,确保义齿舒适度和美观度。BACKGROUND： In recent years, commonly used removable partial denture materials include Vitallium200 material, cobalt-chromium alloys and titanium materials. OBJECTIVE： To explore the value of different removable partial dentures in the repair of dentition defects. METHODS： Ninety cases of dentition defects, including 45 males and 45 females, aged 20-57 years old, were subject to removable partial denture repair. Among them, 30 cases were treated with Vitallium2000 removable partial dentures, 30 cases with titanium removable partial dentures, and 30 cases with cobalt-chromium removable partial denture. Denture inplace rate, incidence rates of denture stomatitis, periodontal disease and secondary caries, patient satisfaction self-evaluation were compared between three groups within 2 years after implantation. RESULTS AND CONCLUSION： Vitallium2000 material group was superior to pure titanium and cobalt-chromium alloy groups in the denture inplace rate, incidence rates of denture stomatitis, periodontal disease and secondary caries （P〈 0.05）. Patients in the Vitallium2000 material group were more satisfied with lightweight and comfort, aesthetics, chewing ability, odor degree of removable partial dentures than those in the other two groups （P 〈 0.05）. These findings suggest that Vitallium2000 removable partial dentures can better improve the denture in place rate, reduce the incidence of denture stomatitis, periodontal disease and secondary caries, ensuring the comfort level and aesthetics of dentures.
