N2  - To investigate mandibular motion patterns in an orthodontic population through the use of the Modjaw® optical tracking system. Materials and Methods: A cohort of 154 orthodontic patients underwent mandibular movement assessment. Skeletal relationships were classified using ANB angles, while dental classification was derived from digital casts. Recordings followed the manufacturer’s guidelines, capturing centric occlusion–maximum intercuspation (CO–MI) discrepancies, maximal mouth opening, Bennett angles, and sagittal condylar guidance. Temporomandibular disorder (TMD) presence was evaluated using DC-TMD questionnaires. Non-parametric statistical tests and Spearman correlation analyses were performed. Results: Mandibular motion showed notable differences across skeletal classifications, particularly in CO–MI discrepancies, Bennett angles, and maximal opening (p < 0.05). Patients with TMD exhibited larger CO–MI discrepancies, though other movement parameters remained largely unaffected. Weak correlations were observed between sagittal condylar guidance and anterior guidance variables. Conclusions: Mandibular motion patterns vary with skeletal type, with Class III patients displaying distinctive characteristics. While TMD symptoms influence CO–MI discrepancies, overall mandibular function appears largely stable.
