The aim of the study was the comparison of the cephalometric results occurring during orthodontic and surgical treatment of patients with mandibular prognathism. Results of patients treated surgically and of patients who underwent complex orthodontic and orthognathic treatment were compared. Additionally, the purpose of the research was to evaluate the psychical state of the prognathic patient: the affect the physical "difference" may have had on his life as well as his own opinion concerning the treatment and its outcome. Cephalometric results using the Segner-Hasund method of two groups of patients were compared: group I (12 patients undergoing surgical treatment), group II (11 patients treated orthodonically and surgically). The X-rays in group I were taken just before the surgical treatment and at least 3 months after the treatment, and in group II, before orthodontic treatment and at least 3 months after surgery was preformed. Additionally patients were asked to answer a questionnaire concerning their self-esteem and approach to the treatment and its results. The comparison ofcephalometric results of the prognathic patient prior and post treatment gives a good insight on changes which take place. The study showed that better cephalometric results were obtained in group II i.e., in patients undergoing orthodontic--orthognathic treatment. Patients of both groups were pleased with the outcomes of the treatment (with a slight emphasis on group II), which lead to the conclusion that treatment of the prognathic patient has a positive influence on his self-esteem and way of life.
