DWS launches DFAB 3-D printer for restorations within 20 minutes

COLOGNE, Germany: After a preview at the Chicago Dental Society’s Midwinter Meeting in the US in February, Italian company DWS will be officially launching its new DFAB 3-D printing solution at the International Dental Show (IDS) in Cologne. The product features the company’s own Photoshade technology, which allows for the production of dental prostheses in natural shades in a single visit.

DFAB is a 3-D printer developed for general dentists and prosthodontists with the purpose of increasing the efficiency and reducing the number of procedures for the production of dental prostheses. It produces up to five-element bridges in less than 20 minutes. The innovation behind this is the Photoshade technology, a system that helps reproduce the shades of the patient’s teeth, giving the prosthesis a natural appearance.

Starting from an STL file, produced after an intra-oral scan, the user selects the shades of the restoration using the software. The colours can be selected from a range between A1 and A3.5 on the VITA scale (VITA Zahnfabrik); as a result, the finished product obtained is customized.

DFAB is an integrated system with disposable cartridges containing TEMPORIS, a Class IIa biocompatible material. Recent studies and tests on this material have shown mechanical strength values that are comparable to a well-established restorative resin material made of hybrid composite.[1] The cartridges are ready to use and were developed to maintain the workplace hygiene, avoiding the risk of accidental contamination. The printer does not produce any noise or dust and does not require tooling.

DFAB has a minimal design that adds value to the dental clinic. It is available in desktop and chairside versions with a 7 in. touch-screen computer.
