printodent® GR-19.1 OA | MSI is the first biomimetic 3D printing resin for the generative production of hard-elastic orthodontic splints. Thanks to the unique MSI® technology, splints made of printodent® GR-19.1 OA | MSI exhibit reduced biofilm adhesion. The effect is based on natural substances that sustainably inhibit the communication of bacteria. Unlike antibiotics, for example, no resistance is formed in this way. The material also has a body temperature-induced thermo effect.
