The purpose of this study was to investigate the characteristics of patients' satisfaction on prosthetic treatment with removable dentures. One hundred and two Full dentures, 95 A-P dentures, and 106 P dentures were analyzed. On each denture group, applying the quantification method of the third type, scores of content and strength of their satisfaction were assigned to each rating grade of the factors constructing the structure of patients' satisfaction.
The following results were obtained.
1. In terms of statistic point of view, the most reasonable rating scales of the satisfaction were graded by the following 3 ratings ;“very satisfied”, “satisfied”, and “not satisfied”.
2. Determinants of dissatisfaction were “dental service” and “structure” in Full denture, “dental service” in A-P denture and “pain” in P denture.
3. Determinants of satisfaction were “esthetics” and “performance” in Full denture, “performance” and “taste” in A-P denture, and “strangeness” in P denture.
4. It is considered that above results should have to be verified with valid methods to measure patients' opinions on denture treatment.
