Use of an optical jaw-tracking system to record mandibular motion for treatment planning and designing interim and definitive prostheses: A dental technique

An overview of the digital occlusion technologies: Intraoral scanners, jaw tracking systems, and computerized occlusal analysis devices

“…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).…”

“…The lower jaw sensor is pow- Photometric devices use one or more cameras to track the position of markers fixed to the mandible, with or without additional markers positioned on the face of the patient (Figure 3B). [29][30][31][32][33] Videobased technologies for the mandibular motion tracking have been reported as highly dependent on the size of the markers and the frame rate of video capture, with smaller markers performing poorly when compared with high frame-per-second recording devices. 83 Some IOSs provide the capability to record the mandibular motion of the patient; however, the accuracy of these IOS recordings is unknown.…”

“…Within the incorporation of digital technologies in dentistry, additional armamentarium such as ultrasonic systems, 26–28 photometric devices, 29–33 and artificial intelligence (AI) 34–37 algorithms have been described for tracking and recording the mandibular motion of the patient 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 26–33 …”

“…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.…”

“…18,19 Similarly, dental articulators have been developed to replicate the mandibular motion of the patient for designing and fabricating dental restorations. [20][21][22][23][24][25] Within the incorporation of digital technologies in dentistry, additional armamentarium such as ultrasonic systems, [26][27][28] photometric devices, [29][30][31][32][33] and artificial intelligence (AI) [34][35][36][37] algorithms have been described for tracking and recording the mandibular motion of the patient. 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.…”
