Assessment of occlusal changes in patients with tooth wear after selective occlusal adjustment assisted by T-Scan
Main Article Content
Abstract
This case series study included 20 patients selected using a convenience sampling method at the High-Tech Center for Dental Examination and Treatment, Institute of Odonto-Stomatology, from July 2024 to September 2025. Key occlusal parameters were evaluated, including occlusion time (OT), center of force (COF), asymmetry of occlusal force (AOF), and the anterior–posterior occlusal force distribution discrepancy (ΔAOD). The results showed that patients with severe tooth wear exhibited occlusal indices outside the normal range, with significant improvements following occlusion time adjustment: OT was reduced to 0.23 s (p < 0.001), COF was located within the ideal zone in 100% of all cases, AOF decreased to 7.65% and ΔAOD approached zero, indicating a shortened mandibular travel distance from initial occlusal contact to maximum intercuspation. Selective occlusal adjustment guided by the T-Scan system demonstrated potential for improving occlusal instability in patients with severe tooth wear.
