This article examines the application of direct 3D printed clear aligners in the rapidly growing pediatric and adolescent orthodontic market. Unlike traditional thermoformed aligners that rely on vacuum-formed plastic sheets over 3D printed models, direct 3D printing uses photopolymer resins to fabricate aligners layer-by-layer via DLP or SLA technologies, achieving superior fit accuracy, customized force delivery, and 30-50% faster production turnaround. With children and adolescents representing the fastest-growing segment in the $13.13 billion global clear aligner market, direct printing addresses unique clinical needs including accommodation of erupting permanent teeth, rapid replacement of lost aligners, and enhanced aesthetics for compliance-sensitive patients. The article also discusses challenges in material development, complex case limitations, and the digital-first workflow powered by intraoral scanning and AI-driven remote monitoring.
