The Experience of Studying the State of Occlusal Relations in Patients with Generalized Periodontitis Who Require Orthopedic Treatment with Non-Removable Structures Using the “T-Scan system”

Abstract

Determining the state of occlusal relations in orthopedic dentistry is an important step both for diagnosis and for treatment. For the purpose of their study, 65 patients with chronic GP of theІst and ІІnd degree of the development who needed an orthopedic treatment, were used the device “T-Scan III”. Patients had a partial (1-3) loss of teeth of III and IV classes according toKennedy; they were divided into two groups. Group I included 35 patients who had included defects and were not previously prosthetic, group II – 30 patients who had poor-quality bridges of different materials that needed replacement. Control was provided by 20 dentally healthy patients with normal occlusal ratios of dentitions. We have determined that patients with GP with included defects in the dentition have significant deviations from the even distribution of occlusalloading on the dental rows in both of the studied classes according to Kennedy, especially those who had not previously been prosthetic. It is necessary to use a computerized analysis of occlusion with the help of the apparatus “T-Scan III” to all of these patients at every orthopedic stage of complex treatment. The precise definition of supra-contacts reduces the possibility of errors and allows achievement of the ideal – 50% to 50% –relationship between the left and right parts of the tooth-jaw system during fitting and fixing of orthopedic structures and keeping it in the process of their exploitation.
