Traditional mechanical articulation provides insight into occlusal relationships but cannot replicate complex mandibular movements accurately. CAD/CAM advancements, including virtual articulators, enable dynamic occlusion analysis using either average-value settings or individualized mandibular movement data, depending on the system used. Patient Specific Motion (PSM) technology, using intraoral scanners to record actual mandibular movements, offers enhanced functional occlusal design. Despite these advancements, challenges such as patient movement and limited residual dentition affect accuracy, highlighting the need for further research into dynamic occlusal registration methods. This study investigates the impact of different occlusal registration techniques on prosthesis design under varying conditions of missing teeth.</p><p><strong>Methods: </strong>Ten participants were examined in an in-vivo study comparing the accuracy of three occlusal registration methods: 1) Static Occlusal Registration (SA), Dynamic Occlusal Registration including 2) Virtual Articulator (VA), and 3) Patient-Specific Motion (PSM).
