Vitallium 2000材料与钴铬合金材料治疗牙列缺损的疗效比较

Effect analysis of Vitallium 2000 materials and Cobalt-chromium alloy materials on removable partial denture by repair dentition defect

目的比较Vitallium 2000材料与钴铬合金材料治疗牙列缺损的疗效。方法选择2013年12月—2015年12月间宁波市北仑区人民医院牙列缺损患者412例,依据患者所用材料,将患者分为钴铬合金组和Vitallium组,每组206例。修复后,比较2组义齿就位率、2W调整率、咀嚼效率、义齿性口炎发生率、不良反应(继发龋、牙周病、基牙不良、基托受损)发生情况及患者对义齿各个方面满意度(美观、舒适、咀嚼功能、语言功能)。结果 Vitallium组就位率明显高于钴铬合金材料组(P<0.05),2W调整率显著低于钴铬合金组(P<0.05)。Vitallium组咀嚼效率明显高于钴铬合金组(P<0.05),义齿性口炎发生率显著低于钴铬合金组(P<0.05)。Vitallium组凝血、牙槽骨吸收过快发生率显著低于钴铬合金组(P<0.05)。Vitallium组继发龋、牙周病、基牙不良与基托受损等不良反应发生率显著低于钴铬合金(均P<0.05)。Vitallium组美观满意度、舒适满意度、咀嚼功能满意度及语言功能满意度显著高于钴铬合金组(均P<0.05)。结论 Vitallium 2000材料在可摘局部义齿修复牙列缺损中效果显著,可有效减少义齿性口炎、不良反应的发生,患者的美观度、舒适度、咀嚼能力及语言能力更高。

Objective To compare the clinical effect of Vitallium 2000 materials and Cobalt-chromium alloy materials on removable partial denture by repair dentition defect. Methods Altogether 412 patients with removable partial denture by repair dentition defect in our hospital from December,2013 to December,2015 were selected and divided into Vitallium2000 group and Cobalt-chromium alloy group based on the scaffold materials,with 206 cases in each group. After repair,the denture placement rate,2 W adjustment rate,chewing efficiency,denture stomatitis rate,adverse reactions（ secondary caries,periodontal disease,abutment defect,and basement impairment）,and satisfaction（ beautiful,comfortable,chewable,linguistic） of two groups were compared. Results The denture placement rate of Vitallium 2000 was significantly higher than that of Cobalt-chromium alloy（ P〈 0. 05）,and 2 W adjustment rate was significantly lower than that of Cobalt-chromium alloy（ P〈 0. 05）. The masticatory efficiency of Vitallium 2000 was significantly higher than that of cobalt-chromium alloy（ P〈 0. 05）,and denture stomatitis rate was significantly lower than that of cobalt-chromium alloy（ P〈 0. 05）. The coagulation,thrombosis and alveolar bone absorption rate of Vitallium 2000 group were significantly lower than those of cobalt-chromium alloy group（ P〈 0. 05）. The secondary caries,periodontal disease,abutment failure and adverse reactions of Vitallium 2000 group were significantly lower than those of cobalt-chromium alloy group（ P〈 0. 05）. Shape satisfaction,comfort satisfaction,masticatory function satisfaction and language function satisfaction of Vitallium 2000 were significantly higher than those of cobalt-chromium alloy（ P〈 0. 05）. Conclusion Vitallium 2000 has significant effect in repairing dentition defect with removable partial denture,could effectively reduce the occurrence of denture stomatitis,coagulation,thrombosis and adverse reactions,and improve the aesthetic appearance,comfort,chewing ability and language ability.
