Abstract (≈100 words)
Chairside 3D printing is changing restorative and prosthodontic workflows by enabling same‑day models, splints, surgical guides and provisional restorations. Systems such as Rapid Shape ONE and PRO 20 combine DLP technology with validated materials and end‑to‑end wash/cure automation. This article reviews technologies (SLA/DLP/LCD), material classes and regulatory status, and sets out practical chairside workflows, infection‑prevention requirements and quality control. Evidence is summarised for provisional crowns, occlusal splints, dentures and implant guides, with limitations and research gaps noted. A decision framework supports practices considering adoption, including training, costs, space and safety. Ten MCQs and image specifications are provided for accreditation.
Key Takeaways
- Chairside DLP/LCD printers can deliver accurate, repeatable models, splints and provisionals when combined with disciplined post‑processing and QC.
- Rapid Shape ONE (chairside) and PRO 20 (high‑throughput) offer validated resin libraries and automated wash/cure that reduce handling exposure and variability [Rapid Shape, 2025].
- Evidence is strongest for provisional restorations, splints and guides; long‑term data for definitive crowns remain limited [Prpić, 2023; Shi, 2023; Abdelnabi, 2024].
- Safety matters: uncured resin is a skin/eye irritant; follow CDC/ADA infection‑control guidance and local waste rules [CDC, 2024; ADA, 2022].
- Adoption should be driven by workflow demand, trained staff, compliant materials and documented QA, not marketing claims.
Learning Objectives
After completing this activity, participants should be able to:
1. Distinguish SLA, DLP and LCD printing and relate technology choice to chairside outcomes.
2. Describe Rapid Shape ONE and PRO 20 features and when each fits clinical or small‑lab needs.
3. Select and validate materials for provisionals, splints, dentures and guides, including post‑processing parameters.
4. Implement a safe, auditable chairside workflow from scan to cure with QC checkpoints.
5. Apply infection‑prevention measures specific to resin printing and solvent handling.
6. Appraise claims vs evidence and use a decision tree to judge in‑house printing versus laboratory outsourcing
