Sustainable clear aligner practice in esthetic and prosthetic dentistry: a scoping review for practical implementation.

Purpose: The purpose of this scoping review is to systematically map and synthesize the available evidence on sustainable practices in Clear Aligner Therapy (CAT), including materials, workflows, and end-of-life management with specific focus on material properties and clinical applications relevant to prosthodontic practice. It aims to systematically map the available evidence on sustainable practices in clear aligner therapy (CAT), including materials, workflows, and end-of-life management, with a specific focus on practical implementation and implications for pre-restorative and prosthodontic care. Material and methods: Following PRISMA-ScR guidelines, databases including PubMed, Scopus, Web of Science, and Google Scholar were searched. Result: Out of 419 records, 21 studies met the inclusion criteria. The field is emerging, with the majority (57.1%) published in 2024. Study designs included reviews (52.4%) and Conclusion: Sustainable CAT can reduce material and chemical burdens through digital workflows, the evidence base, largely comprising recent narrative and Clinical implications: Orthodontists should consider both material properties and environmental impact when selecting clear aligners for pre-restorative tooth positioning, occlusal therapy, or interdisciplinary treatment. The "ProSustain-P" framework provides practical guidance for implementing sustainable material practices in prosthodontic workflows, potentially reducing costs while addressing growing patient demand for environmentally responsible treatment options.
