EnvisionTEC’s E-Guard is a biocompatible crystal clear material for the production of accurate splints and retainers on the Perfactory® line of 3D Printers. The results produced by combining E-Guard with EnvisionTEC technology are superior to traditional methods of manufacturing bite guards and night guards. It is a clear material, allowing for maximum visibility. High resolution 3D printing allows for precise fit. Finally, the cost of high quality splints and retainers can be dramatically lower when produced using E-Guard on an EnvisionTEC 3D printer in comparison to previous machining methods, making EnvisionTEC the clear choice for any digital dental laboratory.
