二次功能印模法全口义齿对改善无牙颌患者口腔健康的效果评价

Evaluation of the effect of secondary functional impression complete denture on improving oral health of edentulous patients

目的:评价对无牙颌患者运用二次功能印模法进行全口义齿修复的临床效果。方法:对433例无牙颌患者运用二次功能印模法进行全口义齿修复,修复前后使用老年口腔健康评价指数(Geriatric Oral Health Assessment Index,GOHAI)评估患者口腔健康相关生活质量。根据患者是否有义齿修复史,分为无义齿修复史、局部可摘义齿修复史和全口义齿修复史3组。在全口义齿修复史组中,选取30例患者,使用修复前旧义齿及新义齿咀嚼双色口香糖,采用ViewGum分析计算口香糖的混合程度数据(SDHue值)。采用SPSS 26.0软件包对数据进行统计学分析。结果:3组患者修复后口腔健康相关生活质量均有提升,修复后1个月GOHAI指数均显著高于修复前(P<0.05)。在全口义齿修复史组中,30例患者修复后SDHue值显著低于修复前(P<0.05)。结论:二次功能性印模法操作简便快捷,能够提升患者对全口义齿修复后的满意度。

PURPOSE:To evaluate the clinical effect of complete denture restoration in edentulous patients using secondary functional impression.METHODS:Complete denture restoration was performed in 433 edentulous patients using secondary functional impression.The Geriatric Oral Health Assessment Index(GOHAI)was used to evaluate patients'oral health-related quality of life before and after restoration.All patients were divided into 3 groups according to whether they had a history of denture restoration:no denture group(ND),removable partial denture group(RPD),complete denture group(CD).In CD group,30 patients were asked to chew two-colour gum.The SDhue value was evaluated by using ViewGum software.SPSS 26.0 software package was used for data analysis.RESULTS:The oral health-related quality of life was improved in all the 3 groups after restoration,and the GOHAI index 1 month after restoration was significantly higher than that before restoration(P<0.05).In CD group,SDHue value of 30 patients after restoration was significantly lower than that before restoration(P<0.05).CONCLUSIONS:Secondary functional impression is simple and fast,and can improve the satisfaction of patients after complete denture restoration.
