ABSTRACT:
The method of manufacturing a dental crown for use in replacing a deteriorated tooth includes the steps of making an impression of the patient's teeth including the deteriorated tooth and then making a first model from the impression. The deteriorated tooth is then extracted and a dental post installed in its place. An impression is made of the patient's teeth with the dental post and from this impression a second model is made. By use of heat and pressure a thin plastic foil is applied over the second model. By use of heat and pressure a thicker plastic foil form is made from the first model. Moldable crown forming material is then placed on the plastic foil encapsulated prepared tooth on the second model. The plastic foil form is then placed over the foil covered second mold to shape the moldable crown forming material. The crown forming material is then hardened to create a crown that is removed from off of the foil covered second model and out of the plastic foil form. The created crown is then further hardened and polished as necessary and can then be cemented onto the implanted dental post.
