Printed vs. foil fabricated aligner - an in vitro study
The adjustment of teeth using aligners is a popular trend. Up to now, these plastic parts were manufactured using thermoforming processes. Through the development of a new plastic, it is now possible to produce 3D printed aligners.
The range of commercially available biocompatible resins for the production of medical articles by stereolithography is very much limited due to the excessive brittleness of photopolymers. The biocompatible resin system researched within the scope of the interdisciplinary cooperation between the University Hospital for Dentistry and the University of Leoben, Austria offers unique ductility and elasticity in the cured state and is therefore ideally suited for direct production of transparent dental splints with 3D printing.
Using a single tooth deflection on a plaster model, 3D printed aligners together with Duran and Essix foils were measured and compared in-vitro.
