METHOD OF CREATING AN ACCURATE BONE AND SOFT-TISSUE DIGITAL DENTAL MODEL
First Claim
1. 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 comprising the acts of:
- obtaining a first dataset associated with hard tissue of the patient'"'"'s mouth;
obtaining a second dataset associated with soft tissue of the patient'"'"'s mouth; and
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.

9. A method for developing a surgical guide for guiding the insertion of at least one dental implant into a desired location in a patient'"'"'s mouth, the method comprising the acts of:
-
obtaining a first dataset associated with hard tissue of the patient'"'"'s mouth and a second dataset associated with soft tissue of the patient'"'"'s mouth; forming a 3-D anatomic digital model including the first dataset and the second dataset; creating a surgical plan defined by the 3-D anatomic digital model, the surgical plan including virtual implant positions; scanning a cast model of the patient'"'"'s mouth to obtain a third dataset; combining the third dataset with the 3-D anatomic digital model; placing at least one implant analog in the cast material in a location replicating the location of the at least one virtual implant in accord with the surgical plan; attaching at least one implant-analog mount and at least one master tube into the cast model in accordance with the surgical plan to form a master cast; pouring a flowable material over the master cast and around the at least one master tube; allowing the flowable material to harden, the hardened material forming the surgical guide; and removing the at least one implant-analog mount and the surgical guide from the master cast. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of developing a surgical guide for guiding the insertion of at least one dental implant into a desired location in a patient'"'"'s mouth, the method comprising the acts of:
-
scanning the inside of the patient'"'"'s mouth to obtain a first dataset associated with bone tissue, teeth, or a combination thereof; taking an impression of the patient'"'"'s mouth; scanning the impression to obtain a second dataset associated with a gingival surface; merging the first dataset with the second dataset to form a 3-D anatomic digital model having gingival thickness data; forming a cast model from the impression; creating a surgical plan having virtual implants via the 3-D anatomic digital model, the virtual implants having location information associated therewith; scanning the cast model to obtain a third dataset; using a robot, placing at least one implant analog in the cast model at a position dictated by the virtual implant location information. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method of developing a 3-D model of the patient'"'"'s mouth, the method comprising the acts of:
-
scanning the inside of the patient'"'"'s mouth to obtain a first dataset including data associated with the jawbone, bone tissue, teeth, or combinations thereof; scanning the inside of the patient'"'"'s mouth or an impression of the patient'"'"'s mouth to obtain a second dataset including data associated with the gingival surface; merging the first dataset with the second dataset to form a combined dataset; removing overlapping data from the combined dataset to form a modified dataset; and adding soft tissue data associated with the region between the gingival surface and the jawbone to the combined dataset.

25. A method of placing a dental implant and prosthesis in a patient'"'"'s mouth, the method comprising the acts of:
-
developing a 3-D anatomic digital model based on hard tissue data obtained from a computed tomography scan of the patient'"'"'s mouth and soft tissue data obtained from an intra-oral scan or a dental impression of the patient'"'"'s mouth; developing a cast model of the patient'"'"'s mouth; scanning the cast model to obtain cast data; merging the 3-D anatomic digital model with the cast data to obtain merged data; developing a master cast by installing a dental implant analog to replicate a desired location of the dental implant into the cast model using the merged data; developing on 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; placing the surgical guide in the patient'"'"'s mouth; installing the dental implant through the at least one opening in the surgical guide; after installing the dental implant, removing the surgical guide from the patient'"'"'s mouth; and attaching a dental prosthesis to the dental implant.
