[Profile-altering interventions as preventive measures (author's transl)].

Operations to improve the profile in abnormal positions of the mandible serve as preventive measures on the one hand for improving and harmonizing the external shape of the face and for improving the function of chewing on the other, with consequent prevention of premature loss of teeth, periodontosis and complaints of the temporomandibular joint, and preventing the appearance of digestive diseases. The different bite and mandibular abnormalities are discussed in groups classified according to their operability.
