“…It has also been proposed that a T-SCAN is a consistent and reproducible method for occlusal examination. (Floriani et al, 2022). As a (Pyakurel et al, 2013).Dental implants are usually directly osseointegrated with the bone, eliminating the space for physiological movement.…”

Introduction: The occlusal force of the teeth in the dental arch and the remaining adjacent natural teeth will change after implant restoration with a free-end missing tooth. This study intends to use the T-SCAN III scanner to collect dynamic quantitative data before and after the restoration of free-end implants and to explore the application of the T-SCAN III in redistributing the occlusal force of free-end implants.Methods: In this study, 24 patients with free-end implant restoration were selected, and their occlusion was tested before, immediately after, and 3 months after implant restoration.Results: In all 24 cases, the bite force of the first natural tooth adjacent to the implanted tooth after restoration changed from 19.12% ± 9.48%–12.93% ± 11.47% (p < 0.01). For additional data analysis, all cases were further subdivided by single implant and fixed bridge restorations. In 17 cases, there was a successful follow-up after 3 months. The percentage of the total bite force of dental arch with implant increased from 41.92% ± 10.78%–53.06% ± 10.71% (p < 0.01).Discussion: This study shows that the free-end implant restoration protects the remaining natural teeth, and the patient’s missing dental arch bite force improves within 3 months of implant restoration.

“…The distribution of the occlusal contacts in static and dynamic occlusion was compared by means of the digital method (T-Scan III) and the analog method (articulating paper) and the study came to a conclusion that the digital and analog methods showed a significant agreement and moderate correlation, irrespective of the type of complete denture. Also, they recommended that The T-Scan III digital system seems to be a consistent and reproducible method to analyze occlusion [21].…”

“…Universal Testing machine [21] was used for applying vertical static loads ranging between 0 and 100 Newton on the loading points bilaterally between the lower second premolar and the lower first molar and unilaterally on loading point between the right lower second premolar and first molar. A T-shaped load applicator was made to fit on the prosthesis bilaterally between the distal aspect of lower second premolar and mesial aspect of lower first molar (Figure 16), and a Chisel shaped load applicator was used to apply load unilaterally on the right side to represent the loaded side between second premolar and first molar (Figure 17).…”

AIM: The study aimed to compare two different methods for occlusal analysis and adjustment of implant-supported prostheses (computerized T-scan and articulating papers) regarding the stresses transmitted to the implants. MATERIALS AND METHODS: Seven patients with completely edentulous mandible opposing dentate maxilla have been selected and four implants have been inserted. Two identical mandibular zirconia implant supported prostheses have been constructed for each patient. Occlusal analysis and adjustments have been done using T-scan for one prosthesis and using articulating papers for the other prosthesis. Two identical acrylic casts for the mandibular arch (with four implant analogs on each cast) have been constructed for each patient. The prostheses on their acrylic casts were applied to cyclic loading using chewing simulator of 250,000 cycle (1 year loading). Strain gauges have been installed mesial and distal to each implant (28 implants of T-scan group and 28 implants of articulating paper group) and strain gauge analysis was conducted using the universal testing machine upon the application of bilateral and unilateral load after cyclic loading. Data were collected, tabulated, and statistically analyzed. RESULTS: Higher micro strain values were found around implants among articulating paper group than T-scan group and that difference was statistically insignificant under bilateral loading and statistically significant under unilateral loading. CONCLUSION: T-scan allows better occlusal stresses distribution as it brings additional information regarding force intensity and occlusal timing resulting in less stresses transmitted around implants.

“…Various heights of the pots were used to perform the drop impact test. A distribution cloud map was produced that complied with the data obtained from the pressure distribution measurement equipment during testing, including the contact stress, contact area, and peak contact stress [19,20]. After each free-drop impact test, the matrix loss rate and collision impact force were measured.…”

Currently, the simulation parameters for the model of the interaction between the transplanter, the plug seedlings, the soil, and the pot damage mechanism still need to be clarified. The optimization design of the planters and the improvement of planting quality are still urgent issues that need to be solved. In this paper, the simulation parameters of the pot and the soil were calibrated based on the pressure distribution measurement technology. With the actual collision impact force and matrix loss rate as the targets, a four-factor, three-level orthogonal test was designed to obtain the optimal parameters. Through the optimization analysis of the experimental results, it could be concluded that the pot–soil restitution coefficient, the pot–soil static friction coefficient, the pot–soil rolling friction coefficient, and the surface energy were 0.31, 0.88, 0.35, and 1.07 J/m2, respectively. The experimental verification of the optimal parameter combination showed that the relative error of the collision impact force was 1.65% and that the relative error of the matrix loss rate was 2.32%, which verified the model’s reliability. Based on the optimal parameters, the movement law of the hole tray seedlings was studied at different positions during the transplanting process. The plug seedlings collided not only with the planter but also with the soil, which led to the breakage and looseness of the pot structure. The relative error between the matrix loss rate of the transplanter inserting soil, the matrix loss rate of the transplanter that did not enter the soil, and the simulated matrix loss rate was less than 10%, which further proved the accuracy of the simulation model.
