Article Abstract
This paper presents our work on the research process of virtual articulator simulation. Firstly, plaster models of upper jaw and low jaw are measured by 3D-optical measuring system and processed to get the available data. Secondly, complex physical modeling of the jaw motion is simplified and decomposed to a series of position transform, such as translation, rotation, etc.. Thirdly, opening/closing movement and laterotrusion is simulated by real-time updating display. Fourthly, the efficient collision detection algorithm is applied to dynamically compute occlusal contact regions and cutaway view. Finally, the current shortage of the virtual articulator simulation is discussed in detail and research prospect is forecasted.

Dynamic joint balancing provides consistent gap prediction without a learning curve in robotic-assisted total knee arthroplasty.

Dynamic joint balancing (DJB) in robotic-assisted total knee arthroplasty (RATKA) allows surgeons to simulate implant positioning and predict soft tissue balance intraoperatively before bone resection. Although virtual gap (VG) estimation is integral to this process, its accuracy in predicting the final gap (FG) after implantation remains uncertain. We conducted a retrospective analysis of 77 knees in 61 patients undergoing RATKA with the MAKO system.

Introduction: To compensate for inadequate clinical exposure to temporomandibular disorders (TMD) among dental students during predoctoral training, a virtual patient-based learning (VPBL) platform was developed for integration into the TMD predoctoral curriculum. This study tested the VPBL's content validity among 10 orofacial pain (OFP) experts responsible for TMD education at U.S.

Introduction: Tracheostomy (TQT) is a procedure that maintains airway patency, and its effectiveness depends on the selection of appropriate equipment and specialized care. Knowledge gained during nursing and postgraduate training is essential to ensure safety and minimize risks in these patients. Identify the level of knowledge regarding TQT care among nurses at a hospital in the Canary Islands (Spain).

The overall goal of this study was to develop a computational framework to quantify hip, knee, and ankle joint forces during exoskeletal-assisted walking (EAW) in the ReWalk P6.0, an FDA-approved lower-extremity exoskeleton. The first objective was to quantify hip, knee, and ankle joint forces during unassisted walking and compare the results to existing in vivo and simulation data.

Robotic-assisted thoracic surgery is increasingly recognized as a valuable approach for the most complex of pulmonary resections, offering high-definition 3D visualization, enhanced instrument articulation and tremor-free precision. Compared to open thoracotomy, the robotic platform is associated with reduced peri-operative morbidity, shorter hospital stays and faster post-operative recovery. However, sublobar resections such as segmentectomies remain technically demanding, particularly in the context of anatomical variations, as illustrated in this case.
