An imaging and marking method and system for locating the physical placement location of a plurality of brackets on a patient's study cast is disclosed. The system includes a three-dimensional scanner; a computer including a processor, memory associated with the processor, one or more input devices, and a video display unit; and a marking device. The scanner gathers an array of data points from the study cast. The computer generates a virtual model of the teeth from the array of scanned data points. Each tooth that is desired to be moved by the orthodontist (i.e., in an orthodontic treatment plan) may be manually severed or “cut” from the other portions of the virtual model and manually dragged with a computer input device by the orthodontist from a starting position (e.g., that position where the tooth originally begins) to a finished position (e.g., the position that the tooth will be physically located at the end of the treatment plan). The computer stores the beginning and ending vectors of each manipulated teeth. The orthodontist points and clicks with a marking tool on the position of the tooth where a physical bracket may be located to induce the necessary forces on the tooth to move the physical tooth from the starting position to the finished position. This point is also stored in memory by the computer. An output file of the bracket placement locations is transmitted to a placement device. The placement device takes the output file and physically places a bracket onto a physical model using the bracket location information. Subsequent to the placement operation, the model can serve as a template or guide to locate brackets for an indirect bonding style tray.
