To this end, first, the occlusal surface popular silicon 1232 is inserted into the bottom of the sprint 1230 of the lower structure 121. In addition, the dental model is recorded using the plaster model. Then, the upper structure 122 is coupled to the lower structure 121 in which the tooth state of the subject is recorded to prepare the guide stent before the guide hole is formed. Here, in the first embodiment of the present invention by using a gypsum model recorded the state of the subject's teeth and jaw bones to describe the case of the subject's teeth in the guide stent 120 as an example, the present invention instead of the plaster model It is also possible to directly record the subject's dental condition on the guide stent 120 using the subject's dentition, in which case the step S101 can be omitted.

As described above, when the guide stent 120 is formed before the formation of the guide hole, the display unit 110 is coupled to the guide stent 120 to acquire CT data during subsequent CT imaging (S103). Then, the lower structure 121 of the guide stent 120 in which the subject's dental state is recorded is mounted on the subject's teeth, and then CT imaging is performed to obtain CT data (S104). Here, the CT data includes the position data of the mapping marker 111 attached to the display unit 110.

It is also possible to record the subject's dental condition on the occlusal surface popular silicone 1232 of the guide stent 120 after combining the guide stent 120 with.

On the other hand, the implant placement information generating device 200 generates the implant placement information on the basis of the implant position and direction of the implant planned according to the subject's dental state and CT data obtained through CT imaging (S105). To this end, the implant placement information generating device 200 reproduces the jaw of the subject in the three-dimensional image using the CT data. Then, the implant placement position and direction planned for the subject's dental condition is recorded on the reproduced jaw as shown in FIG. 8. In this way, the image recording the position and direction for implantation in the three-dimensional image reproducing the jawbone of the subject may be provided to the subject. Meanwhile, in the first embodiment of the present invention, a 3D image in which the implant placement position and direction are recorded in the jawbone of the subject may be provided to the subject using the 3D image guided navigation guide based on the CT data.

Meanwhile, the implant placement information generating device 200 linearly extends the implant placement position and direction recorded in the jaw of the subject in the three-dimensional image to the upper structure 122 of the guide stent 120 to guide the guide hole to the guide stent. The implantation information of the implant to be formed is generated.

Thereafter, the implant placement information generating device 200 removes the images of the lower structure 121 and the display unit 110 from the three-dimensional image in which the implant placement information is recorded, thereby forming a guide hole in the upper structure 122. Obtain and output the information.

When the coordinate information is output, the guide stent 120 and the display unit 110 are separated, and then guide holes are formed in the upper structure 122 of the guide stent 120 based on the coordinate information through the guide hole generator 300. The guide stent to be used for implant placement is completed by linearly extending the guide hole formed in the upper structure 122 to the lower structure 121 (S106). Here, in the first embodiment of the present invention, the guide structure may be formed after the upper structure 122 is separated from the lower structure 121, and the guide in a state in which the upper structure 122 is coupled to the lower structure 121. Holes may also be formed.

Meanwhile, after the guide hole is formed in the guide stent, the guide hole may be strengthened so that the guide hole may be damaged or changed during implant placement so that an error does not occur in the implant placement. For example, a metal cylinder may be inserted into the guide hole to reinforce the guide hole.

Meanwhile, in order to transmit coordinate information to the upper structure 122 based on the 3D image in which the implant placement information is recorded, a process of synchronizing the 3D image with the upper structure 122 is necessary. To this end, in an embodiment of the present invention, after obtaining CT data through CT imaging, the coordinate system of the 3D CT data and the coordinate system of the upper structure 122 are synchronized based on the markers 111 for mapping.
