Abstract
PURPOSE: This study aimed to evaluate and compare occlusal adaptation and bite force distribution following the placement of stainless steel crowns (SSCs) and BioFlx crowns in children aged 4-8 years using the T-scan system. MATERIALS AND METHODS: A randomized controlled clinical trial was conducted on 50 children requiring pulpectomy and crown restoration in primary molars. The participants were randomly assigned to receive either SSCs (n = 25) or BioFlx crowns (n = 25). Occlusal contacts and bite force parameters were recorded at three intervals: baseline (precementation), immediately postcementation, and at 2 weeks postplacement using the T-scan system. Statistical analysis was carried out using Friedman's test, Mann-Whitney U test, Cochran's Q test, and McNemar's test. A p-value < 0.05 was considered statistically significant. RESULTS: Both crown types initially disturbed occlusal equilibrium and bite force distribution immediately after placement. At the 2-week follow-up, the BioFlx group demonstrated significantly better occlusal adaptation, with a quicker return to baseline bite force values and fewer persistent premature contacts compared to the SSC group (p < 0.05). Older children (>7 years) showed faster occlusal adaptation in both groups, especially in the BioFlx group. CONCLUSION: BioFlx crowns provided superior short-term occlusal adaptation and faster normalization of bite force distribution when compared to SSCs. Their flexibility and biocompatibility may contribute to enhanced patient comfort and rapid occlusal integration. The T-scan system served as a reliable tool for objectively assessing occlusal changes in pediatric restorative procedures. HOW TO CITE THIS ARTICLE: Singh T, Devashish, Kannan A, et al.
