3D Printing and Digital Dentistry: New Materials, Applications, and Integrations for Dentists

3D printing for dentistry

Step inside a dental clinic today and you’ll find a totally different set of tools than you would have just a few years ago. Dentistry is well on its way to fully embracing digital workflows and 3D printing, replacing messy alginate impressions with digital scans and complicated manual techniques with machining and computer aided manufacturing.

This shouldn't surprise you given every set of teeth is unique, meaning that every dental appliance has to be customised. The need for mass customisation, and the small size of the final product, makes this perfect for 3D printing. While material properties have been a barrier to broader application of this technology, new biocompatible materials are enabling dentists to 3D print a wider range of products.

To date, Formlabs dental users have completed over 150,000 3D prints. With the release of new Dental Resins, Formlabs is greatly expanding the range of dental products that the Form 2 can produce. With 3D prints every bit as accurate as larger machines that cost $75,000 or more, the Form 2 is increasingly the go to 3D printer for dentistry professionals.

Matt Roberts from CDT, talks about his experience operating four Form 2 3D printers for various applications in his dental lab.

Meet the New Resins
The new dental resins from Formlabs add a range of new capabilities to the Form 2 SLA 3D printer including crown and bridge models, splints, retainers, and soon dentures.

Dental Model Resin
Designed for crown and bridge models with removable dies, Dental Model Resin is a high precision, high accuracy resin. Print crisp margins and contacts within ± 35 microns and removable dies with consistently tight fit. A smooth, matte surface finish and color similar to gypsum make it easy to switch from an analog to a digital model workflow and production.

Dental LT Clear Resin
A Class IIa biocompatible resin, Formlabs Dental LT Clear’s high resistance to wear and fracture make it the ideal resin for splints, retainers, and other direct printed orthodontic devices. This clear material polishes to high optical transparency for beautiful final products.

3D Printed Dentures
Formlabs are pushing the boundaries of digital and 3D printed dentistry by developing the world's first fully integrated, end to end workflow for manufacturing high quality, high accuracy 3D printed dentures. Clinical studies and workflow tests are currently in development at Formlabs and their partner dental clinics, with new biocompatible Denture Base and Teeth Resins coming this year.
