Method for pre-operative visualization of instrumentation used with a surgical guide for dental implant placement
A surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.

14. A method of developing manufacturing information for a surgical guide to be placed in a patient's mouth, comprising:
developing, by use of a computer system, a virtual model of the patient's mouth incorporating surgical-region scan data of a surgical region of the patient's mouth at which at least one dental implant is to be located and opposing-condition scan data from a scan of the patient's mouth in an opened position, the opposing-condition scan data including dental conditions opposite the surgical region;
developing, with the use of the virtual model, a surgical plan that includes the location of the at least one dental implant to be placed in the patient's mouth;
developing a virtual surgical guide based on the location of the at least one dental implant and the surgical-region scan data;
