Background and Aim: The quality of dental treatment is one of the factors that affects life Satisfaction in the elderly. Patients expect optimal function, esthetics, and speech from their prosthesis, while durability and technical considerations are also important for clinicians. In addition, social and psychological factors as well as costs can affect patient Satisfaction. This study aimed to evaluate the relationship of life Satisfaction with Satisfaction with implant treatment. Materials and Methods: In this cross-sectional study, a total of 67 partially edentulous patients (molars and premolars) who had undergone prosthetic treatment 2-6 months earlier were recruited by convenience sampling in Isfahan, Iran. Data were collected by a questionnaire and analyzed using SPSS version 24 via t-test, ANOVA, and Pearson’ s correlation test. Results: The mean score of Satisfaction with implant treatment was 33. 70 ± 5. 15 while the mean score of Satisfaction with old age was 24. 28 ± 4. 75 out of 45. There was a significant correlation (r=0. 748) between life Satisfaction and Satisfaction with implant treatment (P=0. 001). Patients with higher level of education were more satisfied with their treatment (r=0. 407, P=0. 023). There was a significant difference between Satisfaction with single crowns and bridges, and the use of single crowns was associated with greater level of Satisfaction with treatment (P=0. 004). Conclusion: Satisfaction with implant treatment is significantly correlated with life Satisfaction among the elderly. Gender and surgical history were not correlated with treatment Satisfaction, but higher educational level and having a single crown were associated with greater patient Satisfaction.
