Dental supplies from Lütjenburg since 1954
Johannes Weithas GmbH & Co. KG was founded on 1 October 1954 by Johannes Weithas and is today run as a medium-sized family business in its third generation. The company from Lütjenburg in Schleswig-Holstein has been consistently specialized in plastics and teeth since its founding and distributes dental plastics (Weiton/Weitur), prosthetic teeth, the flexible nylon system Valplast, consumables for CAD/CAM and 3D printing, and technical machines. The Weiton and Weitur PMMA-based plastics are offered as heat-curing and self-curing polymers and meet standards such as ISO 20795-1; the prosthetic teeth are manufactured in a highly automated production process using Selective Injection-Compression Moulding (SICM).
