Optical jaw tracking systems are designed to record the static maxillomandibular relationship and the mandibular motion of a patient, including excursive movements and mastication pattern. This digital data acquisition technology can be integrated into diagnostic and treatment planning procedures, as well as into designing dental prostheses. A step-by-step protocol to record a patient's digital data, including the repeatable reference position of the jaw or centric relation, by using an intraoral scanner, Kois deprogrammer, and optical jaw tracking system is described. The data are then processed in the software program of the jaw tracking system to locate centric occlusion.

Objectives: To establish a quantitative method for objectively assessing 3-dimensional (3D) mandibular trajectories and comparing clinical evaluations with computational analyses.
Methods: In total, 184 volunteers were recruited and grouped into control (n = 121) and temporomandibular disorder (TMD) groups (n = 63) according to the dual-axis DC/TMD checklist. 3D trajectories were generated by integrating mandibular motion and cone beam computed tomography (CBCT) records.

Purpose: Optical tracking devices (OTDs) hold promise for enhancing patient-centered prostheses, but their efficacy remains underexplored. This clinical study aimed to comprehensively evaluate differences in static and dynamic occlusions among occlusal appliances fabricated using optical tracking, conventional tracking, and average articulator values (AAVs), providing insights into their efficacy in clinical and research-based practices.
Materials And Methods: Twelve dentate participants aged over 25 years, with Angle Class I and II occlusal relationships, were enrolled.

Speech Sound Disorders (SSDs) are prevalent communication problems in children that pose significant barriers to academic success and social participation. Accurate diagnosis is key to mitigating life-long impacts. We are developing a novel software solution-the Speech Movement and Acoustic Analysis Tracking (SMAAT) system to facilitate rapid and objective assessment of motor speech control issues underlying SSD.

Article Synopsis
- The study focuses on the difficulties of designing prosthetic occlusal surfaces that accurately reflect a patient's jaw movements, highlighting the need for precision in avoiding occlusal interferences during lateral excursions.
- It aimed to evaluate the effectiveness of digitally replicating mandibular movements to identify and correct these interferences in CAD-CAM zirconia crowns through two different adjustment methods.
- Results showed that crowns adjusted using only buccal records (Group I) had higher lateral pressure measurements compared to those adjusted with both buccal and lateral records (Group II), suggesting that the latter may lead to better occlusion outcomes.
