Summary: This study investigated the impact of occlusal contact situation and occlusal adjustment on wear, roughness, and fracture force of molar crowns. The results showed that resin composite crowns had higher wear area and depth, as well as lower fracture forces. Adjusted crowns exhibited increased wear areas and depths. For zirconia crowns, the adjustment resulted in greater wear area and depth, as well as lower fracture forces. These findings emphasize the importance of adapting occlusal design and adjustment to improve the performance and stability of zirconia and resin composite crowns.

Summary: This study evaluated the damage sensitivity and strength degradation of translucent zirconia under mouth-motion simulations. The results showed that 5Y-PSZ exhibited greater strength degradation compared to 3Y-PSZ, with 50 N load significantly affecting the zirconia strengths.

Summary: Tooth splinting does not improve survival of mobile teeth in patients with advanced periodontitis, while occlusal adjustment may lead to improved clinical attachment level in teeth with mobility or premature contacts. The effect of occlusal adjustment on other periodontal parameters remains unclear.

Summary: This study aimed to assess the overall performance of static and dynamic occlusion in post-orthodontic patients using quantified methods and to determine the correlation between the two states of occlusion. The results showed that the pre-treatment Angle's classification did not affect the ABO-OGS score. In dynamic motions, post-orthodontic cases still presented dental casts interference. Therefore, both static and dynamic occlusion should be extensively evaluated before ending orthodontic treatment.

Summary: The study found a positive correlation between occlusal contact area and masticatory performance, with the highest correlation observed in the 0-149 micrometer range of interocclusal thickness. Increasing occlusal contact area led to improved masticatory performance, indicating a statistically significant relationship between the two variables.

Summary: The objective of this study was to determine the accuracy of T-scan system and Cerec Omnicam system in evaluating occlusal contact. Results showed that in the intercuspal position, the Cerec Omnicam system demonstrated higher accuracy in assessing occlusal contact compared to the T-scan system.

Summary: In this study, the accuracy and reproducibility of occlusal contact points visualized by articulating foil were compared with those calculated by three different intraoral scanners. The results showed that the occlusal contact points visualized by the scanners were significantly less accurate and less reproducible compared with the foil. Among the scanners tested, the Trios 3 showed significantly better results in terms of sensitivity and accuracy.

Summary: This study aimed to analyze the distribution of bite forces in individuals with different occlusal characteristics. The study found that subjects with Class III malocclusion, decreased overjet, and decreased overbite had higher bite forces in the posterior teeth compared to other groups.

Summary: The occlusal contacts were comparable between aligner and bracket treatment completion and after 3-6 months of retention. However, marked contact force asymmetry persisted in some patients even after the retention period.

Summary: Occlusal analysis is crucial for identifying disharmony in occlusion. T-scan provides a valuable method for assessing occlusal problems and can be used in periodontitis patients to check their occlusal pattern. Further research is needed to determine the necessity of occlusal adjustment in periodontal treatment.

Summary: An electronic search of scientific literature identified 145 articles comparing conventional and modern occlusal indicators in dentistry. While modern techniques like the T-Scan system and intraoral scanner were generally supported, the diverse materials and methods used in the studies prevent any single method from being declared the best for occlusal analysis, instead requiring a complementary approach.

Summary: T scans are a breakthrough technology that accurately analyzes a patient's occlusion with minimal errors. Although they are used for prosthodontic rehabilitation to plan for replacements, the high cost of equipment and lack of large-scale studies on T scans for determining occlusion are concerns.
