This study was performed to determine the ef-fect of patients’ personality traits on their degree of satisfaction with prosthetic-implant therapy.<br> Materials and Methods: In this study, 51 partially edentulous patients who had lost 1 to 4 maxillary premolars and 2 months had passed since their prosthetic treatment were selected by convenience sampling. The data collection tool was a researcher-designed questionnaire on satisfaction with fixed implant therapy and NEO five-factor inventory (NEO-FFI), the validity and reliability of which had been proven in previous studies. The relationship between the personality scores and satisfaction was ana-lyzed by t-test and ANOVA. The significance level was set at P<0.05.<br> Results: The mean score of satisfaction was 34.3±4.37. The mean personality score was 199.96±20.64. There was no significant relationship between the patient satisfaction and age or sex (P>0.05). The less educated patients were significantly more satisfied with their treatment (P=0.041). The highest mean score was found for acceptability and the lowest mean was reported for neuroticism. There was a signifi-cant relationship between taking responsibility and satisfaction (P=0.026).<br> Conclusion: The personality traits of individuals affected their satisfaction with the treatment, and the patients who were more responsible were more satisfied with their treatment outcome.
