BACKGROUND: In modern conditions, in the widespread clinical practice in the prosthetics of patients with complete edentulism, the anatomical and physiological method and its modifications have become popular. However, for all its reliability and ease of use, this method is not without drawbacks.

AIM: Improving the effectiveness of complete removable dentures. By developing a new method for determining the central ratio of the jaws.

MATERIAL AND METHODS: An innovative method for determining the central ratio of the jaws was created by improving the functional-physiological method for determining the central ratio of the jaws, using a gnatometer and teleradiographic examination.

RESULTS: 100 prostheses were made by this method for 74 patients. A comparative correlation analysis of teleradiographic images with old prostheses before treatment, with a gnatometer in the oral cavity during treatment, and with new prostheses 2 months after treatment was carried out.

CONCLUSION: The proposed method for determining the CSF allows highly accurate, in accordance with individual anatomical parameters and features, to determine the bite height and central occlusion of the patient as a model for the reconstruction of the future dentition, taking into account and in accordance with Angle’s skeletal class.
