Applications of Rapid Prototyping in Dentistry

Abstract

Rapid prototyping (RP) technology has revolutionized dentistry by integrating computer-aided design and manufacturing (CAD/CAM) to enhance precision, efficiency, and customization in dental applications. RP enables the fabrication of accurate anatomical models, surgical guides, prostheses, and orthodontic devices, reducing manual intervention and improving patient outcomes. The key RP techniques include stereolithography (SLA), selective laser sintering (SLS), inkjet-based 3D printing, and fused deposition modeling (FDM), each offering unique advantages in dental applications. While RP significantly enhances treatment planning, fabrication speed, and accuracy, challenges such as high costs, equipment maintenance, and material limitations remain. The continuous advancements in RP, including AI integration and bioprinting, promise to further transform digital dentistry.
