Objective: To find out the relation between personality factors of edentulous patients and the degree of their satisfaction to the complete dentures.
Methods: Under the condition of controlling quality of complete dentures, 165 subjects were investigated by using the patient denture satisfaction questionnaire and the revised Cattell's 16 personality factors questionnaire after wearing the complete dentures for one and three months.
Results: The personality factors of edentulous patients such as conscientiousness (G factor), shrewdness (N factor) and so on do affect their denture satisfaction in every aspect of the dentures.
Conclusion: The oral prosthodontists not only need improving technological quality of prostheses but also need paying attention to patients' psychological characteristics.
