Background and Objectives: Edentulism is considered to be an impediment impacting both patients' quality of life and their nutrition. Conventional
complete dentures are still a preferred treatment. However, there is no consensus on the most important factors which could substantially reduce the risk of patient dissatisfaction. This study evaluated the following determinants concerning patient satisfaction with complete maxillary and mandibular
dentures: sex, denture-related functional and aesthetic aspects, and the degree of
bone resorption. Materials and Methods: This study included 70 patients aged 34-81 years of age. All
complete dentures were made by following the same technology. Visual analogue scales were used to assess patients' overall satisfaction with
dentures, comfort, ability to speak and chew, denture aesthetics, stability, and ease of
prosthesis cleaning. Satisfaction with upper and lower
dentures was rated separately. The degree of
bone resorption was classified by using the Kalk and de Baat (1989) method. Results: The mean (SD) age of the study participants was 67.3 (10.4) years; 65.7% (n = 46) were females and 34.3% (n = 24) were males. There were no significant sex-based differences in resorption of the maxilla or mandibula. There were significant differences between maxillary and mandibular
dentures, with lower mean satisfaction scores concerning chewing and maxillary
complete dentures, and in regard to stability and comfort for mandibular
complete dentures. There was a non-significant overall lower satisfaction with increased age. In multivariate analysis for mandibular
complete dentures, aesthetics and stability significantly predicted the patient's comfort levels, and the patient's comfort significantly predicted overall satisfaction. For maxillary
complete dentures, patient comfort and aesthetics significantly predicted overall patient satisfaction. Conclusions: Age, sex, and degree of resorption were not associated with patient satisfaction with
complete dentures. Overall, patient satisfaction with both maxillary and mandibular
complete dentures was related to their comfort level and denture aesthetics, and patient comfort itself was associated with stability of the mandibular denture.
