Wehmer was officially established as a company in 1943 by Bruno Friedrich Wehmer in Park Ridge, Illinois. The Wehmer Corporation has been dedicated to serving the needs of orthodontic professionals for over sixty years. The original product line was limited to cephalometric radiography equipment, but expanded in the 1960’s to include model trimmers and vacuum plaster mixers. These core products still create the foundation of their business activities. Dental Planet sells new and refurbished Wehmer items.
