- FIGS. 9 and 10 illustrate conceptual diagrams of an example in which an implant image generating system corrects coordinate information of STL data and CT data.
- the STL image generated by the STL data and the CT image generated based on the CT data may define the distance or direction of the tooth with respect to the reference plate 62.
- the reference plate 62 shown in Figs. 9 and 10 shows the same thing.
- FIGS. 9 and 10 Before comparing FIGS. 9 and 10, the image of FIGS. 9 and 10 will be described.
- the distance between the reference plates 62 and both ends of the tooth 80 are d1 and d2, respectively.
- the CT image illustrated in FIG. 10 corresponds to a CT image generated based on CT data before coordinate information is corrected.
- the distance d3 between both ends of the tooth 81 is biased in the direction A toward one side of the tooth 81 by the distance d7.
- the deviation of the direction may be due to the image distortion caused by the prosthesis or prosthesis that the error of the CT image is located around the teeth (80).
- the distance d4 between the reference plate 62 and the teeth 80 shown in FIG. 10 is corrected.
- -> d1, d5-> d2 the distance between the reference plate 62 and each tooth of the patient can be corrected by referring to the definition of STL data using this method. Can proceed accordingly.
- the reference plate 62 may be a reference point for correcting the distance or direction to each tooth in the CT data.
- the coordinate information of the reference plate 62 should be corrected in accordance with the STL data before correcting the coordinate information of the CT data.
- the coordinate information of the teeth included in the CT data may be corrected based on the STL data.
- the shape and coordinate information of each tooth represented in the CT data may be resized by the STL data.
- the CT image and the STL image formed by the CT data and the STL data may have the same size.
- the CT image is coated with the exoskeleton of the gum implemented in the STL image to determine the shape and density of the tooth and the gum. It can be expressed.
- An image in which the shape of the tooth and the gum is realized by combining CT data and STL data is defined as a hybrid image, which may have a shape illustrated in FIG. 11.
