Each subject's mandibular movement was recorded twice with a 1\u2010week interval. Five parameters\u2014sagittal condylar inclination (SCI) angle, incisal guide angle, Bennett angle, lateral condylar inclination angle, and Fischer's angle\u2014were acquired for further analysis. The precision of the jaw motion tracking systems was evaluated by comparing the results of two measurements of the same parameter. Simultaneously, cone beam computed tomography (CBCT) was utilized during the initial data acquisition and was aligned with intercuspal position (ICP) and edge\u2010to\u2010edge occlusion intraoral scan data. Bone landmarks were used to calculate bilateral SCI as a reference for comparison with the SCI values from each jaw motion tracking system. An independent\u2010sample\n t<\/jats:italic>\n \u2010test was conducted to compare parameter differences, with statistical significance set at a\n p<\/jats:italic>\n \u2010value below 0.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n There were no significant differences among the three jaw motion tracking systems regarding the corrected values of SCI, incisal guide angle, Bennett angle, lateral condylar inclination angle, and Fischer's angle during the 1\u2010week interval (\n p\u00a0<\/jats:italic>\n >\u00a00.05). The values of bilateral SCI obtained by CBCT were 48.57\u00a0\u00b1\u00a06.74 (L) and 48.35\u00a0\u00b1\u00a05.28 (R), respectively. No significant differences were found between the reference SCI and those parameters measured by the KaVo ARCUSdigma system and the Modjaw system (\n p\u00a0<\/jats:italic>\n >\u00a00.05), while the results obtained from the SDiMatriX system indicated a significant difference compared to the reference SCI (\n p\u00a0<\/jats:italic>\n <\u00a00.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The three jaw motion tracking systems exhibited favorable results in terms of precision. Regarding trueness, both the KaVo ARCUSdigma system and the Modjaw system demonstrated a satisfactory levels suitable for applications in digital prosthodontics within clinical settings. However, further refinement is needed to enhance the trueness of the SDiMatriX system.<\/jats:p>\n
