摘　　要：目的探讨直接法和间接法在全口义齿重衬中的临床应用效果。方法选择我院2012—2014年就诊的60例无牙颌患者为研究对象,将其分为直接组和间接组,比较两组修复的稳固性、舒适度及留存情况。结果间接法和直接法在重衬舒适度上有明显统计学差异(P=0.000);重衬修复后义齿稳定性在3个月后无统计学差异(P=0.228),6个月及12个月直接法和间接法均有统计学差异(P=0.020,P=0.002);重衬修复后材料留存情况在3个月后无统计学差异(P=0.640),6个月及12个月后直接法和间接法有统计学差异(P=0.045,P=0.000)。结论在进行全口义齿重衬时不论采用软衬材料还是硬衬材料,使用间接法时义齿的稳定性、患者的舒适度以及材料的留存情况都好于直接法,适合临床使用。Objective To explore clinical application effect of the direct method and indirect method in relining of complete denture.Methods Sixty cases of edentulate patients were chosen as research objects,which were divided into direct method group and indirect method group. The stability,comfort level and preservation of the two groups were compared. Results There was a significant difference between the indirect method and the direct method in the comfort of relining（ P = 0.000）. The stability of denture after relining restoration after 3 months had no statistical difference（ P = 0.228）. After 6 months and 12 months there was statistical difference between direct and indirect methods（ P = 0.020,P = 0.002）. Material retention after 3 months had no statistical difference（ P = 0.640）,but after 6 months and 12 months there was statistical difference between direct and indirect methods（ P = 0.045,P = 0.000）. Conclusion When making denture relining regardless of the soft lining material or hard liner material,the stability of the denture,the patient＇s comfort and material conditions of the indirect method are better than those of the direct method,which is suitable for clinical use.
