Abstract
Ninety-five patients suffering from malformation of the jaws have been studied with respect to their biological and psychological complaints. The subjects have completed a questionnaire with fixed response alternatives prior to treatment. It was shown that the psychological factors dominate in the subjects although it is of a more serious nature for only one subject in two. Thirty per cent of the subjects state that they suffer from gastric and intestinal disorders. Seventy per cent justify their wish for treatment by referring to deficient chewing and speech functioning. Jaw malformation appears to be hereditary since several respondents have reported relatives with similar malformation. The subject material is being followed up and a report of reactions after treatment will be made subsequently.
