摘　　要：目的:探讨硬质蜡直接法确定无牙颌后堤区的临床效果。方法:选取自2019.10-2021.06就诊于我院的无牙颌患者32例,随机分为2组(A,B组),每组16例,A组应用硬质蜡直接法,B组应用石膏模型修整法确定上颌后堤区。然后制作全口义齿,在全口义齿戴用1个月、3个月、6个月和12个月采用后堤区相关上颌全口义齿评价表评估义齿疗效。使用SPSS22.0对结果进行统计分析。结果:在前两个时间点,A,B组在固位,黏膜稳定性,戴用舒适性方面无统计学差异(P>0.05),在后两个时间点,A组在黏膜稳定性和戴用舒适性方面优于B组(P<0.05),在固位方面两组无统计学差异(P>0.05)。结论:硬质蜡直接法确定无牙颌后堤区疗效确切,可以满足上颌全口义齿修复的需要。Objective:To explore the clinical efficacy of hard wax direct method in determination of post dam area in restoration of edentulous patients.Methods:32 edentulous patients were randomly divided into two groups(Group A and Group B),each group own 16 patients.The post dam areas of the patients were determined by hard wax direct method(Group A)and cast trimming method(Group B)separately.Then the complete dentures were fabricated,the efficacy of the CDs were evaluated by post dam related efficacy form.SPSS 22.0 was used to analyze the data.Results:At the first two time points,no statistical difference was found between the two groups as for the scores of retention,mucosa stability and comfort ability(P>0.05).At the last two time points,the mucosa stability and comfort ability of Group A is better than that of Group B(P<0.05),and no statistical difference was found between the two groups as for retention(P>0.05).Conclusion:The hard wax direct method is effective in determination of post dam area,which can meet the requirements of the restoration of edentulous patients.
