Abstract: PURPOSE: The purpose of this study was to investigate the patient satisfaction and the clinical effect of biofunctional complete denture via questionnaire survey. METHODS: Fifty-six patients(26 males and 30 females) with biofunctional complete denture were asked to fill in a questionnaire about satisfaction and the type-variety of food after repair for 1 week, 1 month and 3 months during regular follow-up visits or telephone visits. SPSS 26.0 software package was used to analyze the data. RESULTS: After 3 months of wearing bio-functional complete denture, the average score of the five indicators of aesthetic degree, speech function, chewing function, retention function and comfort level of the patients were >6, reaching the level of "satisfactory" or "fair"; among which the aesthetic degree was the highest (7.71±1.46).The food type score reached 33.96±1.21 at the third month. Repeated measures ANOVA showed that each group of indexes changed significantly over time (P<0.05). Except that the mean value of aesthetics score was equal at 3 months and 6 months, the other indexes all increased along time. Among 56 patients, two had 5 or more times of modification due to pain, accounting for 3.57%. CONCLUSIONS: Bio-functional complete denture can achieve good clinical effect in the early stage of denture repair in patients with dentition loss.
