Abstract:
1. A method of performing guided surgery in a patient's mouth, comprising: taking a CT-scan of the patient's mouth to develop CT-scan data; developing, on a 3D-computer model, a surgical plan based on the CT-scan data, the surgical plan including at least one virtual implant, the virtual implant having virtual-implant location data and virtual implant orientation data corresponding to a non-rotational feature on the virtual implant; based on the surgical plan, manufacturing a surgical guide to be placed in the patient's mouth for installing an implant in the patient's mouth at substantially the same location and orientation as the virtual implant on the 3D-computer model; based on the CT-scan data and the virtual-implant location and orientation data from the surgical plan, manufacturing, via rapid prototyping, a physical model of the patient's mouth having an integral implant analog structure at substantially the same location and orientation as the virtual implant on the 3D-computer model, the integral implant analog structure being made of the same material as other parts of the rapid-prototyped physical model, the rapid-prototyped physical model including a contoured opening that is sized and shaped based on a size and shape of a custom abutment to be installed on the implant in the patient's mouth, the integral implant analog structure being located within the contoured opening; developing a custom prosthesis on the physical model, the developing including mounting the custom abutment at least partially within the contoured opening and on the integral implant analog structure and using the mounted custom abutment to create the custom prosthesis, the custom prosthesis including tooth-shaped material that fits on the custom abutment; performing surgery to place the implant in the patient's mouth as physically guided by the surgical guide in accordance with the surgical plan; and installing the custom abutment and the custom prosthesis on the implant in the patient's mouth.
