It is unclear whether the replacement of conventional dentures with mandibular two implant-retained overdentures alters the diet selection and thus improves nutritional status and quality of life of elderly edentulous persons. In this randomized clinical trial, the objective was to explore the effectiveness of IODNEED programme. Population was Thai male and female, aged over 65years and edentulous for at least 1 year, n=33 in each group, living in Pathumthani Province, Thailand. Intervention was Mandibular two implant-retained Overdentures (IOD) plus NEED (Nutritional Empowerment in Edentulous people with Dentures). Comparison was among IODNEED, IOD only; Conventional dentures (CD) plus NEED and CD only. Outcome was post-treatment differences in satisfaction, oral heath related quality of life and nutritional status and anthropometric and blood parameters among the groups and measured pretest, post 1 month, post 3 months and post 6 months. The research results found that all general characteristics and pretest mean scores of most of the measured variables were not statistically significant difference among the four groups (p-value >.05). Pretest mean scores of nearly all of variables measured among the four groups were not significant different (p-value >.05). At post 6 months assessment, in IODNEED group, the best improvement was seen in most of the variables than other three groups such as oral health related quality of life, masticatory function, satisfaction, nutritional status, body mass index, daily diet intake, and 6 out of 7 items of blood nutrient parameters were significantly higher than pretest (p-value <.001). Comparison between IODNEED and IOD, mean scores of serum albumin, serum Iron, and red blood cells were significantly increased ((p-value <.001) in IODNEED. Between IODNEED and CDNEED, nearly all of the variables such as oral heath related quality of life; mastication function, nutritional status, and 4 out of 7 blood parameters were significantly increased in IODNEED (p-value < .02). From the results of correlation and regression analysis of cost-effectiveness, IODNEED was better than IOD and CDNEED was better than CD in term of oral health related quality of life and satisfaction (p-value < .001). Regarding masticatory function, IOD was 6 times more effective than CD, in our studied population (p-value < .001). we can concluded that “IODNEED” program had more effective in improvement of oral health related quality of life, mastication function, satisfaction for mandibular, nutritional status, BMI, body fat percentage (skin fold thickness), and blood parameters. Moreover, it can also be concluded that “NEED” had not only improvement in mean scores of studied parameters but also effective by cost. Regular participatory nutritional empowerment and isometric exercise should be provided in conjunction with mandibular two implant-retained overdentures in elderly edentulous Thai citizens
