Objectives Occlusion plays an important role in the retention and stability of dental restorations. Aim of this study was to analyze occlusal loading detected on dental elements in patients with unilateral partial edentulism—class III Kennedy, before and immediately after prosthetic treatment with a zirconia-based bridge in maximal intercuspation position with the help of electronic system T-scan III. Materials and Methods The research sample consisted of a total of 60 patients who, based on the preset selection criteria, were divided into two groups: control group with 30 (100%) patients with intact dentition (Gr1) and study group with 30 (100%) patients with unilateral partial edentulism—class III Kennedy, analyzed before prosthetic treatment (Gr2) and immediately after prosthetic treatment with a zirconia-based bridge (Gr3). Results In Gr1, the highest average force applied for individual tooth had the tooth numbers: 17–14.6 ± 9.9%, 26–11.9 ± 6.8%, and 27–11.7 ± 6.8%. The lowest average value was registered for the teeth number 22–1.4 ± 1.3%, 12–1.9 ± 3.8%, and 13–2.9 ± 2.7%. In the group Gr2, the highest average force applied for individual tooth had the tooth numbers: 17–12.9 ± 35.6 and 21–9.6 ± 13.9%, whereas the lowest in teeth 24–2.7 ± 5.2 and 27–3.4 ± 6.8. In Gr3, the highest average force applied for individual tooth had the tooth numbers: 17–11.8 ± 15.4 and 14–9.8 ± 10.9%, whereas the lowest in the tooth 22–2.1 ± 2.6. Conclusion This study demonstrated that all patients with the loss of teeth showed occlusal discrepancies and functional disharmony. During the delivery of zirconia restorations in the future a careful analysis of occlusal contacts should be performed. T-scan III technology reduces the subjective interpretation of occlusal analysis data allowing records and measures the contacts between the teeth.

Objective To compare bite force distributions in corresponding mouth regions between postorthodontic patients who underwent nonextraction and extraction approaches using the T-Scan III system (Tekscan, Inc, Massachusetts, United States). Materials and Methods Thirty-six postorthodontic patients were divided into two groups: (1) 18 subjects with the nonextraction treatment and (2) 18 subjects with the extraction of four first-premolar treatments. The measurements were performed using the T-Scan to collect the occlusal bite force at the maximal intercuspal position to generate the bite force in the anterior region (incisors and canines) and posterior region (premolars and molars), the bite force in individual teeth, and the anteroposterior bite force ratio (A-P ratio). Statistical Analysis The mean bite force in each region, individual teeth, and the A-P ratio were compared between the two groups by the Mann–Whitney's U-tests. Within-group comparisons of the mean bite force in each region were performed using Wilcoxon's signed rank tests. Results The bite force in anterior and posterior regions, and the A-P ratio of the nonextraction group show no significant difference compared with the extraction group (p > 0.05). For individual teeth (central incisors, lateral incisors, canines, second premolars, first molars, and second molars), each tooth exhibited nonsignificantly different bite forces (p > 0.05) except for the second molars. The second molars in the nonextraction group had significantly less bite force than in the extraction group (p = 0.001). The comparison of occlusal bite force between the right and left sides showed that in the nonextraction group, the right side had significantly greater force (p < 0.05). In the extraction group, there was no significant difference between the sides (p > 0.05). Conclusion Both nonextraction and extraction orthodontic treated patients exhibited the similar bite force distribution patterns in regions and individual teeth except for the higher occlusal force on the second molars in the extractions compared with the nonextractions.

Introduction: The phases of orthodontic treatment include Initial Leveling and aligning, space closure, finishing detailing, settling, and retention. The phase of finishing and detailing in orthodontic treatment has a crucial role in refining the occlusion and ensuring long-term stability. However, the effectiveness of orthodontic treatment is not solely assessed by the alignment of teeth and jaws but also by achieving stable occlusion posttreatment. Hence, the study aims to evaluate postorthodontic occlusion in patients who meet the set criteria of finishing and detailing compared to those who have not, using a digital occlusal analyzer. Materials and methods: The posttreatment records of 42 patients who had undergone debonding after fixed mechanotherapy were evaluated for categorizing the patients based on the inclusion criteria into Groups A and B. The occlusal parameters of the patients were evaluated at time intervals—T1 (30 min after debonding), T2 (3 months after debonding), and T3 (6 months after debonding). The occlusal parameters evaluated were—force distribution in the right and left sides and anterior–posterior force %. Results: In a comparative evaluation between Groups A and B, it was seen that occlusion time, force distribution between the right and left sides, and the anteroposterior force distribution in the anterior and the posterior aspect were higher in Group B as compared to A. Conclusion: The results of our study indicated that in patients who had met the goals of finishing and detailing, the occlusal parameters showed near-ideal values as compared to the patients who had not met the goals of finishing and detailing. Digital analysis obtained using T-Scan is essential during the process of finishing and detailing to obtain a stable and well-balanced occlusion by the end of the orthodontic treatment.
