Abstract:
1. 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: receiving a surgical plan defined by a 3-D anatomic model, the 3-D anatomic model being formed using 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, the surgical plan including at least one virtual implant position; receiving a third dataset derived from scanning a cast model of the patient's mouth; merging the 3-D anatomic model with the third dataset to obtain merged data; by use of the merged data, placing at least one implant analog in the cast model in a location corresponding with the at least one virtual implant position in accordance with the surgical plan; attaching at least one implant-analog mount to the implant analog in the cast model; coupling a master tube to the implant-analog mount on the cast model, the cast model and the implant-analog mount with the master tube coupled thereto forming 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 having the master tube embedded therein, the master tube for guiding the insertion of the dental implant in the patient's mouth when the surgical guide is placed in the patient's mouth; and removing the at least one implant-analog mount and the surgical guide from the master cast.
