Modern dentistry is characterized by the widespread integration of intraoral scanners into digital protocols for orthodontic rehabilitation. However, the variations in the accuracy of digital records of static occlusal relationships require clarification, especially in cases where they are obtained in a standardized manner; these variations are often neglected in a significant number of studies when verifying the accuracy of the intraoral scanning systems used. Aim of the Study. To determine the characteristics of the distribution of occlusal contact areas when using digital bite registries of different locations on intraoral scans in patients without significant dental abnormalities. Research Materials and Methods. The study was conducted at the Department of Restorative Dentistry of Uzhhorod National University and involved an analysis of the distribution of occlusal contact areas based on the location of digital bite registrations during intraoral scanning in patients without significant dental pathologies. The study included 30 patients aged 18 to 45 years. Inclusion criteria included intact dentition (18–11/21–28 and 38–31/41–48) and the absence of significant malocclusions requiring orthodontic treatment. Results. Analysis of the results revealed that when using a unilateral digital occlusal registration, the distribution of occlusal contact areas was markedly irregular, with the largest share of contact area falling on specific sections of the dental arch (in the projection of the recorded occlusal relationships), while other segments demonstrated a significantly smaller contribution to the formation of occlusal contacts (in areas distant from the projection of the recorded occlusal relationships), specifically, the largest share of the contact area was accounted for by the molar regions and averaged 24.8–30.2% of the total occlusal surface area, whereas in the anterior segment of the dentition, this figure decreased to 4.4–13.5%. This distribution pattern indicates an asymmetrically shifted reproducibility of occlusal contacts during unilateral bite registration, which may affect the accuracy of the overall occlusion analysis. Conclusions. The results of the study showed that bilateral bite registration ensures a more even distribution of occlusal contact areas along the entire dental arch, with the proportion of contact area in the anterior segment averaging 10–14%, in the premolar region 19–22%, and in the molar region 26–30%, and is also characterized by a lower incidence of critical occlusal interferences. With a bilateral approach, the risk of asymmetric displacement is reduced during the reconstruction of occlusal contacts based on the results of intraoral scanning.
