BEGO's validated cleaning method for 3D-printed restorations made of VarseoSmile Crown plus and VarseoSmile Temp, using the universal cleaning liquid for 3D printing materials InovaPrint wash*, makes the digital workflow even more advantageous and flexible for the user.

VarseoSmile Crown plus is the world's first approved ceramic-filled hybrid material for 3D printing of permanent restorations. It offers 3D printing users the ability to produce definitive crowns, inlays, table tops, onlays and veneers in minutes. VarseoSmile Temp is a tooth-colored resin for 3D printing temporary crowns and bridges, inlays, onlays and veneers. Both materials have a specific ceramic content, which causes a whitish layer on the surface of the printed objects when using the previously approved cleaning methods (with ethanol 96% or isopropanol). After cleaning, it is therefore necessary to blast the object surfaces with a polishing agent (e.g. BEGO Perlablast® micro) to achieve a homogeneous appearance of the restorations. With the newly approved cleaning method using InovaPrint wash, the blasting step is obsolete.

"Extensive tests from the ISO 10993 series of standards on biocompatibility prove the high safety of 3D-printed objects after cleaning with surfactants and curing with one of the numerous compatible post-curing units," says Marius Kempf, Senior Product Manager 3D Printing at BEGO. "In addition, the validated surfactant is user-friendly, safe and economical, as it contains very little alcohol and has a service life at least three times longer than ethanol. Cleaning with InovaPrint wash is also environmentally friendly because it is biodegradable."

The manufacturing workflow of restorations made of VarseoSmile Crown plus and VarseoSmile Temp thus becomes even more user-friendly, as no special cleaning equipment, not even an ultrasonic bath, is needed anymore. Moreover, since blasting of the restorations is no longer required, the workflow remains dust-free. The new cleaning method can be used in combination with all validated 3D printers and post-curing units.
