Abstract: A method for adapting a crown to a clasp and rest of an existing partial denture without depriving a patient of the partial denture during the time the crown is being fabricated in a dental laboratory. The method comprises the steps of fabricating an accurate pick-up impression of the clasp and rest in a dentist's office, fabricating an accurate model of the clasp and rest in a dental laboratory, and incorporating the clasp and rest model in a model at the dental laboratory which is used for fabricating a crown. The fabrication of the accurate clasp and rest model by a dentist includes the important step of supporting the pick-up impression of the clasp and rest on a dimensionally stable coping over a tooth which has been prepared for the crown.
