Background: The 9th Thai National Oral Health Survey (2023) reported that elderly individuals aged 60-80 years had an average of 15.65 remaining teeth. Of these, 14.65% were completely edentulous and received complete dentures, with 10% experiencing poor mandibular denture retention. Recognizing the significance of this issue, the Ministry of Public Health launched "The Dental Implants in Celebration of His Majesty the King's 72nd Birthday Anniversary Project, July 28, 2024." Objective: To evaluate the effectiveness of Thai-innovated implant-retained mandibular overdentures by comparing oral health-related quality of life, chewing ability, satisfaction and pain perception, before and after participation in the project. Method: This was a quasi-experimental study. Data were collected through interviews with 71 patients participating in the project from 9 healthcare facilities in Khon Kaen Province. Results: The average score of oral health-related quality of life (OIDP index) before treatment was 20.90%. The average chewing efficiency score was 34.21%, and the average satisfaction score was 56.80%. After treatment, the average OIDP index decreased to 0.59%, and the average chewing efficiency increased to 97.07%, which both values were statistically significantly different (p-value < .001). The average satisfaction score after treatment was 97%, indicating the highest level of satisfaction. Pain scores during dental implant surgery were significantly lower than the pain experienced during tooth extraction, with a statistically significant difference (p-value < .001). Conclusion: The use of Thai-innovated dental implant-retained overdentures in this project resulted in an average improvement in chewing efficiency by 2.84 times and enhancing oral health-related quality of life.
