3D printers for dentistry
Introduction
Definition and context of 3D printers in dentistry
3D printers for dentistry represent an innovative technology that allows the digital and personalized manufacturing of dental devices through additive processes. This technology has revolutionized the dental field by facilitating the rapid and accurate production of prostheses, study models, surgical guides and other elements necessary for advanced dental treatments.
The use of 3D printing in dentistry is part of the digitalization of the health sector, where the integration of computer-aided design (CAD) and computer-aided manufacturing (CAM) allows a significant improvement in the accuracy, delivery times and customization of dental products, benefiting both professionals and patients.
3D printing technology applied to dentistry
Main dental 3D printing technologies
The most commonly used 3D printing technologies in dentistry include stereolithography (SLA), fused deposition printing (FDM), selective laser sintering (SLS), and Digital Light Processing (DLP) technology. Each of these technologies has specific characteristics that make them more suitable for certain types of dental applications.
SLA and DLP technology are the most common in dentistry due to their high resolution and precision, allowing models and parts to be manufactured with extremely fine details. These techniques use photosensitive resins that are cured layer by layer using ultraviolet light, which guarantees great surface quality and dimensional adaptation.
On the other hand, FDM technology, although less precise, is mainly used to create conceptual models and surgical guides, thanks to its low cost and ease of use. SLS, which uses powder and lasers to fuse particles, is most common in the manufacturing of metal components, including some types of dental implants.
