Assessment of adaptive mechanisms to obturators of the upper jaw according to the data of electronic axiography and cone-beam computer tomography

Abstract

Was to assess the adaptation of patients to obturator at different periods of adaptation using objective digital methods of analysis: axiography, cone-beam computer tomography, digital facial scans, and intraoral scanning. The study comprised 17 patients with postoperative defects of the upper jaw at different periods of removable obturators usage. In 88.2% of the subjects limited mouth opening and displacement of the mandible to the healthy side was detected. Contracture as a complication can develop in the later stages of rehabilitation. A long-term rehabilitation of patients is recommended using simulators and special gymnastic exercises in order to prevent extra-articular contracture.
