To investigate 98 fixed denture patients' personality traits and the relationship between patients' personality traits and satisfaction with fixed denture restoration.

16PF questionnaire and satisfaction questionnaire were used to study 98 fixed denture patients' personality traits and the relationship between personality traits and general satisfaction and specific satisfaction. The data was analyzed with SPSS17.0 software package.

There were significant differences between 98 fixed denture patients' personality traits and those of health adult in factor B(reasoning), C(emotional stability), E(dominance), F(liveliness), H(social Boldness), I(sensitivity), L(vigilance), N(privateness), O(apprehension), Q(1)(openness to change) and Q(2)(self-reliance). The regression analysis demonstrated that Q4(tension), G(rule-consciousness), L(vigilance), Q(3)(perfectionism), Q(1)(openness to change), N(privateness), A(warmth) and M(abstractedness)in 16PF were correlated with the general satisfaction of patients after fixed denture restorations (F=20.566' P=0.000, R2=0.649), Q(4), L, Q(3), N and M were negatively correlated with their general satisfaction; however G, Q(1) and A were positively correlated with it. Except the sense of stability and avoid of food impaction,L,C, Q(4) and Q(3) were negatively correlated with their satisfaction on aesthetic effectiveness, while A, G, I and E were positively correlated with it. L, Q(4), N and Q(3) were negatively correlated with their mastication satisfaction, while G and Q(1) were positively correlated with it. O and Q(4) were negatively correlated with their comfortable satisfaction, while C was positively correlated with it.

There is close relationship between the personality traits of fixed denture patients and their satisfaction. Meanwhile, the general and specific satisfaction are influenced by different personality traits. It is important to pay more attention to fixed denture patients' personality traits in clinical practice.
