Claim:
1. A method of producing an impression of at least one tooth of a patient, comprising: providing an impression tray; providing a first impression material; filling the impression tray with the first impression material; taking a first impression of the at least one tooth to create a cavity corresponding to a dimension of the at least one tooth, wherein the first impression of the at least one tooth is taken using the impression tray filled with the first impression material, wherein the first impression material is forcibly placed to extend beyond the at least one tooth, such that the first impression material extends past a gingival margin of the patient and into a vestibule of the patient to form a sealing surface in the vestibule of the patient; enlarging a dimension of the cavity corresponding to a dimension of the at least one tooth substantially without enlarging a dimension of the first impression material that was forcibly placed to extend beyond the at least one tooth; providing a second impression material; filling the first impression of the at least one tooth with the second impression material; taking a second impression of the at least one tooth to create a cavity corresponding to a dimension of the at least one tooth, wherein the second impression of the at least one tooth is taken using the first impression of the at least one tooth after enlarging a dimension of the cavity filled with the second impression material and wherein the first impression material that was forcibly placed to extend beyond the at least one tooth is configured to retain the second impression material within the enlarged cavity corresponding to a dimension of the at least one tooth using the sealing surface in the vestibule of the patient and thereby substantially increase a hydraulic pressure on the second impression material within the enlarged cavity.
