title: Fabrication of a duplicate denture from an existing complete denture.
abstract: A technique is presented that describes the fabrication of a duplicate denture using the patient's existing complete denture. This procedure enables the practitioner to offer patients an alternative to being without a denture during a laboratory reline of an existing denture. A vinyl polysiloxane impression material is used to impress the polished surface of the existing denture as well as to block out undercuts on the impression surface of the denture before pouring a stone cast. Because of the stability of the impression material used, most of the laboratory procedures can be accomplished separate from the clinical appointment.
