FIG. 1 is a view showing an implant hole forming guide template according to an embodiment of the present invention, and FIG. 2 is a flowchart of a method of manufacturing an implant hole shaped guide template according to an embodiment of the present invention.

Generally, occasionally, the prosthesis that is attached during daily life after implantation is shaken or damaged. At this time, the screws inside the prosthesis should be adjusted to fix or replace the shaky or damaged prosthesis. However, in order to adjust the screws inside the prosthesis, holes should be made in the prosthesis. At this time, the position of the screw inside the prosthesis can not be known and it is difficult to drill the hole. If the hole is erroneously punctured, the abutment may be damaged, causing pain to the patient and causing financial damage. Thus, according to one embodiment of the present invention, an implant hole forming guide template 100 (hereinafter, referred to as a guide template) capable of guiding a position and an angle at which a hole is drilled in a prosthesis for adjusting a screw is manufactured.

Referring to FIG. 1, a guide template 100 according to an embodiment of the present invention may include a cover portion 10 and a guide portion 20.

The cover portion 10 may cover the prosthesis and at least one actual tooth. The cover portion 10 may include a prosthesis cover portion 12 that covers the prosthesis and a peripheral tooth cover portion 14 that covers at least one actual tooth around the prosthesis.

The prosthetic cover portion 12 may cover all surfaces of the prosthesis exposed in the actual mouth or may cover a portion of the prosthesis. At this time, covering a part of the prosthesis may mean covering the entire upper surface and a part of the side surface of the prosthesis.

The peripheral tooth cover portion 14 may cover at least one actual tooth around the prosthesis. At this time, the actual teeth around the prosthesis may be at least one actual tooth in contact or close proximity. The peripheral tooth cover portion 14 may extend from the prosthesis cover portion 12. The peripheral tooth cover portion 14 covers at least one actual tooth in contact with or in proximity to the prosthesis external prosthesis when the guide template 100 is mounted to form a hole, So as to fix the guide template 100 more firmly using the surrounding teeth. The peripheral tooth cover portion 14 may cover the whole of the actual teeth around the prosthesis or cover a part thereof.

The cover portion 10 may be manufactured to reflect the appearance of the prosthesis and at least one actual tooth.

The guide portion 20 may be formed in a cylindrical or polygonal shape on the cover portion 10, that is, on the prosthesis cover portion 12 at a position covering the prosthesis. The guide portion 20 serves to guide a position and an angle of a hole to be formed in the prosthesis and can be manufactured according to the position and angle of the hole to be formed in the prosthesis. At this time, to form a hole in the prosthesis is to separate the screw attached to the inside of the prosthesis and separate the prosthesis from the implant fixture. Accordingly, the position and angle of formation of the hole to be formed in the prosthesis can be determined according to the mounting position and angle of the screw mounted inside the prosthesis. 2, the implant is composed of an implant fixture 2, an abutment 4, an abutment screw 6 and a prosthesis 8, and the implant fixture 2, the abutment 4, the abutment 4) The screw 6 and the prosthesis 8 can all be aligned and joined together. The position and angle of formation of the hole to be formed in the prosthesis 8 can be determined according to the position and angle at which the implant fixture 2 is mounted.

The guide portion 20 may be formed on the cover portion 12 of the prosthesis 8 in a position corresponding to the position where the implant fixture 2 is mounted. The guide portion 20 may be formed to have the same angle as the angle at which the implant fixture 2 is mounted. The guide portion 20 may include a through hole 25 formed therein. The through hole 25 may be a hole into which a mechanism for forming a hole, such as a drill, is inserted when forming the hole in the actual prosthesis 8. The through hole 25 may be formed to have the same angle as the angle at which the implant fixture 2 is mounted. The through hole 25 may be formed to have a cross sectional area equal to or larger than the cross sectional area of the screw 6 fastened to the abutment 4 or the cross sectional area of the screw 6. Accordingly, the guide portion 20 can be formed to have a cross-sectional area larger than the cross-sectional area of the through-hole 25.

FIG.

The guide template 100 according to an embodiment of the present invention is a tool for guiding a hole to be formed in a prosthesis 8 of an implant that has already undergone the implant treatment. The oral cavity having undergone the implant treatment is passed through a mouth scanner and a computer tomography And can be manufactured based on the generated three-dimensional guide image.

3, an intraoral implant (including implant fixture 2, abutment 4, abutment 4 screw 6, and prosthesis 8) The completed scan is scanned with an oral scanner to generate a three-dimensional scan image as shown in FIG. 4 (210).

On the other hand, the 3D scan image can be scanned by the oral scanner, so that only the appearance of the oral cavity surface area can be scanned, and the tooth and gum images can be obtained in the 3D scan image.

In addition, a 3D CT image can be generated as shown in FIG. 5 by computer tomography of a state in which an intraoral implant has been completed (220).

On the other hand, the creation of a three-dimensional CT image by computer tomography may be performed by combining tomographic images taken with respect to the oral cavity into a three-dimensional CT image. In addition, in the case of a computed tomography, images can be projected to teeth, gums or skin, and images of the bones and the implant fixture 2 can be acquired in a three-dimensional CT image.

The 3D scan image and the 3D CT image are generated (210, 220), and then the 3D scan image and the 3D CT image are synthesized to generate a 3D synthesized image as shown in FIG. 6 (230).

At this time, the three-dimensional composite image is generated so as to be able to see all teeth, gums, pubic bone, and implant fixture 2 as a single image. More specifically, the computed tomography does not accurately show the soft tissue, and since the prosthesis 8 of the implant mounted in the oral cavity is an artifact, not an actual tooth, as shown in FIG. 5, The artifact effect is generated so that the region where the gum and the implant are implanted does not come out exactly. In addition, in the case of a three-dimensional scan image, only the surface is scanned so that the inside of the gingival or pubic bone can not be photographed. Accordingly, a three-dimensional synthetic image is generated by synthesizing a three-dimensional scan image and a three-dimensional CT image so that the teeth, the gums, the pubis, and the implant fixture 2 can be accurately viewed. At this time, in order to make the teeth, gums, pubis, and implant fixture (2) appear well when the 3D scan image and the 3D CT image are synthesized, the teeth and the gum are scanned in a 3D scan image, Dimensional 3D image can be generated by the 3D CT image.

In the meantime, when the screw 6 of the implant abutment 4 is loosened or broken, the screw 6 provided in the prosthesis 8 must be adjusted or loosened. To do so, a hole for reaching the screw 6 is first inserted into the prosthesis 8 ). At this time, it is difficult to determine the position of the screw 6 in the interior of the prosthesis 8, and it is difficult to drill a hole in the prosthesis 8 after the implant procedure is completed. According to an embodiment of the present invention, an implant fixture 2 taken in a computer tomography is used to form a hole by predicting the position of the screw 6 mounted inside the prosthesis 8. The reason for using the implant fixture 2 is that the implant fixture 2, the abutment 4, the screw 6 and the prosthesis 8 are aligned and joined together as described above, The position and angle at which the screw 6 is mounted on the prosthesis 8 can be obtained by using the mounting position and angle of the implant fixture 2, This is because it can be predicted.

After the 3D composite image is generated 230, the position where the actual implant fixture 2 is mounted can be detected from the generated 3D composite image. In this case, in the three-dimensional composite image, the inside of the gum and the pubic portion are composed of a three-dimensional CT image generated by a computer tomography. In the three-dimensional CT image, an artificial implant is clearly displayed as shown in FIG. It is possible to detect the position where the actual implant fixture 2 is mounted in the three-dimensional composite image by detecting the actual implant fixture 2 displayed on the display unit. As shown in FIG. 8, in a three-dimensional composite image, a composite image of a virtual three-dimensional implant fixture (2) can be synthesized at a position where an actual implant fixture (2) (240).

At this time, the imaginary three-dimensional implant fixture 2 image can be generated based on the actual implant fixture 2 on the three-dimensional composite image, and the position and angle at which the actual implant fixture 2 is mounted ≪ / RTI > Specifically, after the actual implant fixture 2 is detected in the 3D composite image, the size or shape of the actual implant fixture 2 can be detected. After the size or shape of the actual implant fixture 2 is detected, a virtual three-dimensional implant fixture 2 image having the same size or shape as the size or shape of the detected actual implant fixture 2 is generated . In addition, the position and angle at which the actual implant fixture 2 is mounted can be detected in the three-dimensional composite image. The generated virtual three-dimensional implant fixture 2 image can be synthesized into a three-dimensional composite image according to the position and angle at which the actual implant fixture 2 is mounted.

After the 3D virtual implant fixture 2 composite image is generated 240, a virtual three-dimensional implant fixture 2 image is synthesized on the 3D virtual implant fixture 2 composite image as shown in FIG. 9A. A three-dimensional guide image can be generated by synthesizing a three-dimensional cylindrical image along the central axis of the three-dimensional implant fixture (2) (250).

At this time, synthesizing the three-dimensional cylindrical image on the imaginary three-dimensional implant fixture 2 image is performed by detecting the central axis of the imaginary three-dimensional implant fixture 2 image and determining the virtual three-dimensional implant fixture 2 And the overlap point of the upper surface B of the virtual three-dimensional implant fixture 2 is set as the center of the lower surface of the cylinder The three-dimensional cylindrical image can be synthesized on the upper surface (B) of the virtual three-dimensional implant fixture (2) so that the three-dimensional cylindrical image has the same central axis as the central axis of the imaginary three-dimensional implant fixture have.

On the other hand, the three-dimensional guide image may be an image obtained by synthesizing a three-dimensional cylinder with an image of an actual prosthesis 8, and a three-dimensional cylindrical image may be partially or totally obscured due to an actual prosthesis 8 image. Meanwhile, the guide template 100 according to an embodiment of the present invention produces a template based on the generated three-dimensional guide image, wherein the three-dimensional cylindrical image is used to manufacture the guide portion 20 of the guide template 100 The guide template 100 can not be manufactured if the entire image is obscured by the actual prosthesis 8 image. Accordingly, the three-dimensional cylindrical image may be long enough to partially protrude from the image of the actual prosthesis 8. Specifically, the three-dimensional cylindrical image may have a length greater than the total height of the implanted implants minus the height of the actual implant fixture 2. Since the three-dimensional cylindrical image has a longer length than the image of the actual prosthesis 8, it can be seen that the three-dimensional guide image is displayed in a protruding manner when viewed from above. On the other hand, the three-dimensional cylindrical image has a length that is longer than the height of the prosthesis 8 having the maximum height among the normally-manufactured prosthesis 8, or the length of the cylindrical portion protruding outside the image of the actual prosthesis 8 Can be set according to the height of the guide portion (20).

The guide template 100 according to an embodiment of the present invention can be manufactured based on the generated three-dimensional guide image. At this time, if the guide template 100 is manufactured without setting the template manufacturing range in the three-dimensional guide image, the guide template 100 is manufactured for all the parts in the three-dimensional guide image, and manufacturing time and manufacturing cost are unnecessarily consumed . Accordingly, in order to manufacture the guide template 100 only for a necessary portion, the template manufacturing range can be set in the three-dimensional guide image (260).

The template manufacturing range may include a prosthesis 8 in which a three-dimensional cylindrical image is synthesized from a three-dimensional guide image as shown in FIG. 10, and at least one actual tooth around the prosthesis 8. At this time, at least one actual tooth around the prosthesis 8 may be an actual tooth on the side of the prosthesis 8 or an actual tooth included in the formation of the guide template 100 from the manufacturer. The manufacturing of the guide template 100 with respect to the portion corresponding to at least one actual tooth around the prosthesis 8 as well as the portion corresponding to the prosthesis 8 requires that the guide template 100, It is preferable to set the actual teeth on both sides of the prosthesis 8 to the template manufacturing range in order to fix the guide template 100 more firmly.

The template manufacturing range for the prosthesis 8 in which the three-dimensional cylindrical image is synthesized may include a portion corresponding to a cylinder protruding from the upper surface of the prosthesis 8 and the prosthesis 8. Here, the portion corresponding to the prosthesis 8 refers to the entire prosthesis 8 exposed in the three-dimensional guide image, or the entire upper surface and the side surface of the prosthesis 8 exposed in the three-dimensional guide image . Here, only the side surface of the prosthesis 8 is partially included. It is not necessary to mount the guide template 100 on the entire prosthesis 8 in order to mount the guide template 100 but only a part (for example, This is because the guide template 100 can be attached to the prosthesis 8 even when only the guide template 100 is attached. In addition, the template manufacturing range for the portion corresponding to the cylinder in the prosthesis 8 in which the three-dimensional cylindrical image is synthesized can be set smaller than the length of the three-dimensional cylindrical image. At this time, if the manufacturing range for the three-dimensional cylindrical image is not set, the through hole 25, which can guide the hole to be formed in the prosthesis 8, may not be formed with respect to the entire three-dimensional cylindrical image. Accordingly, setting the template manufacturing range for the portion corresponding to the cylinder to be smaller than the length of the image of the three-dimensional cylindrical column can guide the hole to be formed in the prosthesis 8 to the portion corresponding to the cylinder in the guide template 100 The diameter of the through-hole 25 can be set smaller than the length of the three-dimensional cylindrical image with respect to the upper side in the height direction.

The template manufacturing range for at least one actual tooth around the prosthesis 8 in the three-dimensional guide image can be set to cover the whole or a part of the actual tooth around the prosthesis 8.
