“…Digital jaw systems that are available both commercially and noncommercially have been described. [26][27][28][29][30][31][32][33][34] The main digital technologies include ultrasonic systems, [26][27][28] infrared optical camera systems, photometric devices, [29][30][31][32][33] IOSs, and AI [34][35][36][37]77 algorithms. Jaw trackers can be classified based on the functional capabilities that the system offers: diagnostic (data acquisition and data analysis) systems or diagnostic and designing systems (Table 1).…”

“…38 Additionally, in some of these systems, the recorded mandibular motion can be integrated into the computer-aided design (CAD) software programs for designing dental prostheses. [26][27][28][29][30][31][32][33] The growing use of intraoral scanners (IOSs) for different dental interventions, 39 including acquiring virtual articulated diagnostic and definitive casts, provides a powerful digital alternative for digitizing and virtually analyzing the static and dynamic dental occlusion of a patient, although the accuracy and reliability of these digital methods for occlusal analysis is still unclear. [40][41][42][43][44][45] Additionally, computerized occlusal analysis devices offer a digital alternative to quantitatively assess and visualize the pressure and timing of occlusal contacts.…”

Objectives Within the development of digital technologies, dental professionals aim to integrate virtual diagnostic articulated casts obtained by using intraoral scanners (IOSs), the mandibular motion of the patient recorded by using an optical jaw tracking system, and the information provided by computerized occlusal analysis systems. This article describes the various digital technologies available for obtaining the digital occlusion of a patient and outlines its challenges and limitations. Overview The factors that influence the accuracy of the maxillomandibular relationship of diagnostic casts obtained by using IOSs are reviewed, as well as the occurrence of occlusal collisions or mesh interpenetrations. Different jaw tracking systems with varying digital technologies including ultrasonic systems, photometric devices, and artificial intelligence algorithms are reviewed. Computerized occlusal analysis systems for detecting occlusal contacts in a time sequential manner with the pressure distribution on the occlusal surfaces are reviewed. Conclusions Digital technologies provide powerful diagnostic and design tools for prosthodontic care. However, the accuracy of these digital technologies for acquiring and analyzing the static and dynamic occlusion need to be further analyzed. Clinical Significance Efficiently implementing digital technologies into dental practice requires an understanding of the limitations and state of current development of the digital acquisition methods for digitizing the static and dynamic occlusion of a patient by using IOSs, digital jaw trackers, and computerized occlusal analysis devices.

“…[7][8][9]12,15,19,20 Regular maintenance protocols are recommended, aiming to prevent major biological and mechanical complications. [7][8][9]12,15,19,20 The incorporation of digital acquisition technologies in dentistry such as facial scanners, [21][22][23][24][25] photogrammetry technologies, [26][27][28] intraoral scanners (IOSs), [29][30][31] and optical jaw tracking systems [32][33][34][35] aim to provide efficiency when compared with conventional methods for planning and performing complete-arch implant-supported prosthodontic care. Studies in the literature assessing the accuracy of these relatively new digital tools are scarce; however, the understanding of these technologies, as well as the review of their clinical applications for this extensive prosthodontic treatment is needed.…”

Objectives To provide an overview about the current approaches to prevent peri‐implant diseases in edentulous patients with complete‐arch implant‐supported prostheses, and to review the clinical applications of the latest digital technologies for implant prosthodontics. Methods A review of the guidelines to prevent peri‐implant diseases in patient's receiving complete‐arch implant‐supported prostheses including facially driven treatment planning procedures using either conventional or digital methods, computer‐aided implant planning procedures, and prosthodontic design variables including the optimal number and distribution of dental implants, implant to abutment connection type, implant or abutment level design, screw‐ or cement‐retained alternatives, prostheses contours, and material selection is provided. Furthermore, an outline of the current therapeutic management approaches to address peri‐implant diseases is reviewed. Conclusions Clinicians should understand and know different planning and design‐related variables that can affect biological and mechanical complication rates of complete‐arch implant‐supported prostheses. Maintenance protocols are fundamental for minimizing biological and mechanical complications.

Long-term excessive forces loading from muscles of mastication during mandibular motions may result in disorders of temporomandibular joint (TMJ), myofascial pain, and restriction of jaw opening and closing. Current analysis of mandibular movements is generally conducted with a single opening, protrusive and lateral movements rather than composite motions that the three can be combined arbitrarily. The objective of this study was to construct theoretical equations reflecting the correlation between composite motions and muscle forces, and consequently to analyze the mandibular composite motions and the tensions of muscles of mastication in multiple dimensions. The muscle performances such as strength, power, and endurance of mandibular motions were analyzed and the effective motion range of each muscle was derived. The mandibular composite motion model was simplified by calculating muscle forces. An orthogonal rotation matrix based on muscle forces was established. A 3D printed mandible was used for in vitro simulation of mandibular motions on a robot and measurements of force were conducted. The theoretical model and forces were verified through a trajectory tracing experiment of mandibular motions driven by a 6-axis robot with force/torque sensors. Through the analysis of the mandibular composite motion model, the motion form was obtained and transferred to guide the motions of the robot. The error between the experimental data obtained by the 6-axis force/torque sensors and the theoretical data was within 0.6 N. Our system provides excellent visualization for analyzing the changes of muscle forces and locations during various mandibular movements. It is useful for clinicians to diagnose and formulate treatment for patients who suffer from (temporomandibular joint disorders) TMDs and restrict jaw movements. The system can potentially offer the comparison before and after treatment of TMDs or jaw surgery. K E Y W O R D Scurve fitting, mandibular composite motions, temporomandibular joint, trajectory tracing Si-peng Ke and Kang-jie Cheng contributed equally to this study.
