Digital Occlusal Analysis and Bite Force Evaluation of the Hall Technique Vs Stainless Steel Crowns in Primary Molars Using T-scan

This randomized controlled clinical trial aims to compare two restorative techniques for managing carious primary molars in children aged 6-9 years: the Hall Technique and conventional stainless-steel crown (SSC) placement. The study evaluates how each technique affects occlusal force distribution, mean bite force, and vertical dimension changes using the T-Scan digital occlusal analysis system. Additional outcomes include temporomandibular joint assessment, child discomfort levels, and parental satisfaction with treatment. Participants are allocated 1:1 to receive either the Hall Technique or conventional SSC restoration, and outcomes are measured at baseline, immediately after treatment, and at 2- and 4-week follow-ups. The study aims to determine whether the minimally invasive Hall Technique provides comparable occlusal function and patient-centered outcomes when compared to traditional SSC preparation methods.
