The process of fabricating a denture which involves the dentist at the chairside and the dental technician in the laboratory. It is normally undertaken in a series of clinical stages which may include primary impressions for the purpose of constructing individually fabricated impression trays, secondary impressions taken in the individually fabricated trays, registration of the jaw relationship including the selection of the tooth shade and mould, trying in the denture with the teeth accurately located in a wax base, and finally fitting the finished appliance. Additional stages may be required for dentures which have a metal framework. Some stages may be omitted in the construction of immediate dentures. Between each clinical stage, the required denture construction is normally undertaken by a dental technician in the laboratory.
