Abstract

A method for automated manufacture of dentures including providing a digital data set of the individual denture to be produced, a digital separation of the model into dental arch and gingival, producing the dental arch from a ceramic or plastic material using cutting technology, producing the denture base through generative or ablative procedures from predominantly (meth-)acrylate-based plastic materials, connecting the dental arch and gingiva through bonding or joining or a combination of bonding and joining.
