Objective: A great number of patients are completely satisfied with a regular denture, on the other hand, numerous patients are still not satisfied with their denture functions despite proper denture manufacture in relation to prosthetic standards.

Aim: To estimate the parameters of satisfaction for patients to improve the health care quality of patients and evaluate the effect of the adaptation period.

Materials and methods: A total of 136 patients who participated in this study were patients with complete dentures (CD), after placement of the CD, the patients were asked some questions (about esthetics, phonetics, comfort, quality of fit, and the masticatory efficiency) and the satisfaction of patients was evaluated by using Likert's scale, then recorded four readings, first at the placement visit, second after 1 month, third after 45 days, and last after 2 months.

Results: The female patients' satisfaction related to phonetics was about 37.8% at the placement visit, but about 91.2% after 2 months; the male patients' satisfaction related to phonetics was about 44% at the placement visit, then 94.6% after 2 months; the female patients' satisfaction as related to esthetics was about 56.6% at the placement visit, but was about 89.8% after 2 months; the male patients' satisfaction as related to esthetics was about 68% at the placement visit, but about 89.4% after 2 months.

Conclusion: The satisfaction of the patient with their CD is affected by many factors such as phonetics, esthetics, comfort levels, the quality of fitness of the denture, and the mastication. The differences between gender in satisfaction in all parameters were non-significant, that is, p > 0.001. The adaptation period has an effect on the satisfaction rate of the completely edentulous patient with their CD.
