Evaluation of Clinical Performance, Shade Matching, and Patient Satisfaction of Different Resin Composite Layering Techniques Using 3D Printed Cast

The aim of this randomized clinical trial is to compare different resin composite layering techniques (monochromatic, complex multichromatic, and single-shaded structurally-colored composite) using 3D printed casts for the restoration of Class IV anterior tooth fractures. The study will evaluate shade matching, overall clinical performance, and patient satisfaction over a 12-month follow-up period.

Inclusion Criteria: * Male or female patients aged 18 years or older. * Good oral hygiene and healthy periodontal status. * Presence of sound adjacent teeth and opposing dentition. * Patients requiring direct Class IV composite restoration in permanent anterior teeth. * Cooperative patients willing to comply with the follow-up visits (12 months). Exclusion Criteria: * Patients with poor oral hygiene or severe systemic diseases. * Teeth with pulpitis, periapical lesions, or requiring endodontic treatment. * Presence of severe bruxism, heavy parafunctional habits, or malocclusion. * Pregnant or lactating females. * Heavy smokers or patients with active periodontal disease.
