“…Additionally, the introduction of a rotating 3-Dimensional ForceView window allows for improved visualization of moving individual force columns during movie playback. The rotating 3-D ForceView enables clinicians to adjust the window's orientation to eliminate overlapping rising and falling force columns, optimizing the viewing experience [11].…”

(1) Background: This study aims to evaluate the occlusal force distribution across different quadrants during the placement of orthodontic retainers fabricated using a biocompatible material via digital design. (2) Materials and Methods: A cohort of 21 patients in the retention phase following orthodontic treatment was included in this study. Intraoral scans were obtained using Trios color (3Shape). For retainer fabrication, the splint studio module of the 3Shape design software was utilized. Occlusal evaluation was performed using T-Scan Novus (Tekscan). The Kolmogorov–Smirnov test, Wilcoxon signed ranks test, and Mann–Whitney U test were used for statistical analysis. (3) Results: The digital design set evenly distributed contacts on all occluding surfaces. These contacts, uniform in area, turned out to be uneven in pressure: right distal—37.14%, right frontal—11.4%, left frontal—11.46%, and left distal—39.99%. (4) Conclusions: The results of the study indicate that the digital design workflow has the capability to achieve uniform contact distribution by area. However, despite the achievement of uniform contact distribution, the study found that there was an unequal distribution of occlusal forces. Specifically, the distal sections of the teeth experienced significantly higher loading compared to the frontal sections.

Introduction: Dental occlusion refers to the static and dynamic relationships that are established between the teeth of the two arches and is an important factor in the homeostasis of the dento-maxillary system. The objective of the present study was to compare two digital occlusal analysis systems: the T-Scan III system and the Medit I600 intraoral scanner. Materials and Methods: The study was carried out on 20 students from the Faculty of Dental Medicine Craiova, whose dental occlusion was assessed with the T-Scan III system and with the Medit I600 intraoral scanner. Dental occlusion was assessed in the maximum intercuspation position, the edge-to-edge protrusion position, and the edge-to-edge position in right and left laterotrusion. The images of the 2D occlusal contact areas obtained by both methods were converted to .jpeg format and then transferred to Adobe Photoshop CS6 2021 (Adobe Systems, San Jose, CA, USA) for comparison. The recorded data were statistically processed. Results: Analyzing the data provided by the two digital occlusal analysis systems, it was found that the T-Scan III system provided data related to the amplitude of the occlusal forces, the surface on which they were distributed (the contact surface), the dynamics of the occlusal contacts, and the proportion in which they were distributed at the level of the two hemiarches, and the Medit I600 intraoral scanner performed an evaluation of the occlusal interface of the two arches, highlighting the extent of the contact areas with the degree of overlapping of the occlusal components. Although both methods of occlusal analysis recorded the highest values for the maximum intercuspation position, the results could not be compared. Conclusions: The two digital systems provide different data in occlusal analysis. As the T-Scan III system is considered the gold standard for occlusal analysis, more studies are needed to understand the data provided by the Medit I600 intraoral scanner and their significance.

The Evolution of the Science of Measured Digital Occlusion

Since its inception in 1984, computerized occlusal analysis technology has revolutionized both dental occlusal science and daily clinical practice by bringing objective precision measurement to the largely subjectively analyzed dental medicine discipline of occlusion. The science of Measured Digital Occlusion is a major clinical advance over traditional, subjectively practiced occlusion. This is because T-Scan measured timing and force metric-based occlusal function parameters guide both the diagnosis of an occlusion's health, but also aid the clinician in obtaining high-precision, high-numerical tolerance measured occlusal function outcomes, that can't be attained without the T-Scan's capacity to make specific occlusal functional measurements. The development of the T-Scan technology has required much iteration over the past 40 years beginning with T-Scan I, then T-Scan II for Windows®, then T-Scan III with turbo recording, to a simplified desktop version introduced in T-Scan 8, to the present day, state of the art occlusal analysis version known as T-Scan 10 Novus. Numerous authors since the mid-1980s have studied the various T-Scan versions, which inspired the manufacturer to improve the hardware and its recording sensors to be more accurate, repeatable, and precise. The present-day Novus recording handle represents a major ergonomic and functional upgrade over the Evolution handle that was used up to T-Scan 8, while the T-Scan 9 software has evolved into T-Scan 10 Novus system, which includes many new high-tech measurement tools like the Digital Impression Overlay (DIO), the Sensitivity Wizard, the Implant Warning Feature, and the Force Eraser tool. All of these new system modifications improve the clinician's ability to diagnose and treat a wide range of occlusal abnormalities. Chapter one's specific aims are to detail the evolution of the differing T-Scan system versions, and outline the functional measured digital occlusion parameters that have been applied in many scientific patient treatment studies that resulted from important system improvements to the T-Scan's accuracy and repeatability, from version to version. Chapter one will also highlight some newly available digital occlusion technologies that somewhat mimic T-Scan, while including a detailed section comparing and contrasting T-Scan data to intraoral scanner (IOS) occlusal representations. Presented studies will illustrate that intraoral scanners (IOS) only prognosticate occlusal contact surface engagement, but do not measure or describe for analysis, occlusal contact force levels or contact timing sequences from within scanned dental arches.
