“…A significantly higher occlusal force percentage was found in the posterior region than the anterior region, which is in agreement with previous studies 21–23 . In addition, a slight difference in the bilateral force distribution was found, indicating slight asymmetry, even in patients with normal occlusion.…”

Dental occlusion varies among individuals, and achieving correct physiological occlusion after osteotomy is essential for the complex functioning of the stomatognathic system. The T-Scan system records the centre of force, first contact, maximum bite force, and maximum intercuspation. The aim of the present study was to investigate the usefulness and consistency of T-Scan in assessing occlusion before and after orthognathic surgery. Occlusal information was evaluated for 30 healthy adults with normal occlusion and 40 patients undergoing orthognathic surgery. T-Scan had a high degree of reliability for consecutive measurements (Pearson correlation, r = 0.98). For most parameters, occlusal distribution was better after surgery than before surgery. More teeth contributed to occlusion at maximum intercuspation after surgery than before surgery (14 vs. 10). In addition, the difference in the posterior force distribution was reduced after surgery (17.6 ± 13.8 vs. 22.7 ± 21.4 before surgery), indicating better occlusal force distribution after surgery. The maximum percentage force on teeth (p = 0.004) and the number of teeth contributing to occlusion (p < 0.001) also differed significantly. Thus, T-Scan is good for assessing occlusal discrepancies and can be used to portray the pre- and post-operative occlusal contact distribution during treatment planning and follow-up.

Aim:The aim of this prospective cohort study was to evaluate the postinsertion posterior single-implant occlusion changes at 3-and 6-month intervals using T-Scan computerized occlusal analysis. Materials and methods:A total of 21 patients received single implant, opposed by natural dentition, in posterior regions of the maxilla or mandible (13 premolar, 8 molar) and were finally restored with cemented-retained metal-ceramic crowns. The occlusal contacts were equilibrated according to the implantprotective occlusion concept to develop light contact with heavy occlusion and no contact with light occlusion in maximum intercuspation. The percentage of force applied to the implant crowns (POFI) and contralateral teeth (POFT) was evaluated using T-Scan computerized occlusal analysis at prosthesis insertion, 3-and 6-month follow-up appointments. The data were statistically analyzed using Friedman test and Wilcoxon post hoc test (α = 0.05). Results:The POFI values at the 6-and 3-month follow-up appointments were significantly higher than those at prostheses insertion (p = 0.001 and p = 0.005 respectively). In addition, there were significant differences between the POFI at 3-and 6-month follow-up (p = 0.020). However, the POFT values at 3-and 6-month follow-up appointments were significantly lower than those at baseline (p < 0.001). Conclusion:The intensity of occlusal contacts of implantsupported prostheses opposed by natural dentition gradually Clinical significance: A periodic occlusal adjustment of implant-supported prostheses is necessary to prevent potential overloading from the movement of opposing natural dentition.

BACKGROUND The proposed experimental design was done to determine if a relationship exists between the occlusal load applied and the size of the markings produced from tooth contact when dental articulating paper and T-Scan are interposed alternatively. OBJECTIVE Objective of this study was to compare the relationship between contact markings on an articulating paper and T Scan for an applied occlusal load. METHODS In this in vitro study, dentulous maxillary and mandibular dies were mounted on a metal jig,articulating paper, and T-Scan sensor were placed alternatively between the casts. Loads simulating occlusal loads began at 25N and incrementally continued upto 450N.The resultant markings (180 marks resulting from articulating paper and 138 marks of T-Scan) were photographed and the marks were analyzed using MOTIC image analysis and sketching. Descriptive statistical analysis was carried out with one-way analysis of variance (ANOVA), student t-test and Karl Pearson’s correlation coefficient method. RESULTS The size of an articulating paper mark may not be a reliable predictor of the actual load content within the occlusal contact. T-Scan gave more predictable results of actual load content within the occlusal contact. CONCLUSIONS Statistically interpretation of the data indicated that with articulating paper, the mark area increased non-linearly with increasing load and there was a false positive result. The characteristics of the paper mark appearance did not describe the amount of occlusal force present on a given tooth. The contact marking obtained using T Scan for an applied occlusal load indicated that the mark area increased with the increase in the load and gave more predictable results of actual load content within the occlusal contact.
