Design outcomes

Primary

MeasureTime frame
Quantitative assessment and comparison of occlusal force distribution and occlusal contact timing in Class I malocclusion patients treated with fixed mechanotherapy versus clear aligners, as recorded using the T-Scan computerized occlusal analysis system.Timepoint: Time Points of Assessment of Outcomes Baseline (T0): Before initiation of orthodontic treatment Post-treatment (T1): Immediately after completion of orthodontic treatment malocclusion patients treated with fixed mechanotherapy versus clear aligners, as recorded using the T-Scan computerized occlusal analysis system.—

Secondary

MeasureTime frame
secondary outcomes can include: Occlusal timing parameters (time to first contact, occlusion time, disclusion time) & left right force asymmetry changes from T0 to T1. Number & location of occlusal contacts (anterior vs posterior) & force distribution per quadrant, comparing fixed mechanotherapy & clear alignersTimepoint: Baseline Before initiation of orthodontic treatment Posttreatment Immediately after completion of orthodontic treatment & appliance removal final aligner stage. if permittedT2 3 months after debonding or delivery of retainers to assess short-term occlusal stability.;NilTimepoint: Nil—
