The aim of this research was to evaluate if the cephalometric analysis would be useful in the evaluation and planning of prosthetic treatment. We used 2 cephalometric roentgenoghrams for each of 17 edentulous subjects, the first one without the use of any prothesis and with the patient in mandibular rest position, and the second immediately after the insertion of the prothesis. Linear and angular cephalometric measurements obtained by the tracing of the anatomic structures seem in these radiographs were used in the evaluation of the relationship of maxilla, mandible and soft-tissue profile of the patients. The data was anlysed and the results showed statistically significant improvement of the soft-tissue profile with a more anterior positioning of the upper and lower lips as well as a proportional increase in the lower facial third. The relationship of between the skeletal bases, before and after the prothesis insertion was not significantly changed, proving that the treatment did not alter the physiologic rest position of the mandible, with positive effects in the tissues and evolved structures. So, the cephaloghram proved to be a useful instrument for prosthetic treatment evaluation.
