Method of creating an accurate bone and soft-tissue digital dental model

摘要

A method of creating a 3-D anatomic digital model for determining a desired location for placing at least one dental implant in a patient's mouth. The method comprises the act of obtaining a first dataset associated with hard tissue of the patient's mouth. The method further comprises the act of obtaining a second dataset associated with soft tissue of the patient's mouth. The method further comprises the act of combining the first dataset and the second dataset to create a detailed structure of hard tissue and soft tissue having variable dimensions over the hard tissue.

1. A method of placing a dental implant and prosthesis or abutment in a patient's mouth, the method comprising the acts of:
receiving a 3-D anatomic model based on hard tissue data derived from a computed tomography scan of the patient's mouth and soft tissue data derived from an intra-oral scan or a dental impression of the patient's mouth; scanning a cast model of the patient's mouth to obtain cast data; merging the 3-D anatomic model with the cast data to obtain merged data; by use of the merged data, developing a master cast by installing into the cast model a dental implant analog to replicate a dental implant at a desired location; and developing, by use of the master cast, a surgical guide to be used in the placement of the dental implant in the patient's mouth, the surgical guide including at least one opening generally adjacent to the dental implant analog; wherein the surgical guide is configured to be placed in the patient's mouth such that the dental implant may be installed through the at least one opening in the surgical guide.
