It is discussed whether psychological factors can be accounted responsible for the intolerance to the wearing of prostheses which can not be explained on dental grounds. Psychopathological, psychometric and psychopathometric investigations brought the following results: 1. Patients with complaints differ significantly from a control group in the variables changeable according to situation: "general somatic discomforts", disturbances of vegetative functions, and "depressive moods". This points to a constitutional predisposition to vegetative irritability and lowered threshold to frustration. 2. Less intelligent persons are less able and prepared to incorporate and accept the prosthesis. 3. Among the personality variables differences in the attributes "uncontrollability and social responsiveness" show up in sample tests. The subjects consider themselves more esteemed, popular and acknowledged. 4. In the majority of subjects the making of the tooth replacement coincided with stressful events.
