In recent years, occlusal surface designs for fixed dental prostheses (FDPs) driven by personalized mandibular movements have been introduced. Although these technological developments are promising, dentists still encounter numerous challenges. The first challenge is the clinical assessment of jaw kinematics. In clinical practice, jaw kinematic findings are used to diagnose and assess temporomandibular disorders pre- and post-treatment, and to monitor treatment progress. In addition, the recorded motion data is utilized to fabricate FDPs via a computer-aided design/computer-aided manufacturing system. Altered jaw kinematics reflects both oro-facial motor behavioral adaptation and articular impairment. Thus, dentists must address altered jaw kinematics resulting from motor behavior adaptation and normal kinematics to manufacture dental prostheses using digital technology. The second challenge is establishing optimal occlusal contact. Ideal occlusal contact involves tripodal contact on the same pair of teeth or when the supporting cusp has three points of contact around its tip. However, in patients with balanced occlusion and severe tooth wear, it is often difficult to establish optimal A-B-C contact on molar occlusal surfaces in clinical practice. In other words, removing occlusal interference while maintaining occlusal contact in the intercuspal position in these patients is challenging. Additionally, the occlusal surface design must involve adequate interocclusal clearance and contact to restore masticatory efficiency. Based on the results of this study, we propose a manufacturing process to establish optimal occlusal contacts using tight and intermediate contact areas through digital technology. Finally, we would like to discuss the dental, medical, and social significance of this technology and its future prospects.
