## Abstract

A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid prototype. Rapid prototype dimensional information is developed. The rapid prototype dimensional information is transferred to a rapid prototyping machine which fabricate a rapid prototype of the patient's dentition as well as a dental implant analog position.
