Next, the fixing member 50 (shown in FIG. 7) is fixed to the alveolar bone 3 (shown in FIG. 7) of the patient who is the target of the implant procedure (S2).

Next, after placing the denture on the patient's alveolar bone, the patient's mouth is imaged to obtain data data1 (S3). For example, imaging may be done by CT.

Next, the image is captured to obtain data data2 (S4).

Next, the data (data1, 2; for example, image data) obtained through the imaging is matched to create the implant planning data (data3) (S5).

Next, the data data2 is processed to reflect the position of the fixing member 50 (shown in FIG. 7) based on the data data3 obtained through implant planning (S6). That is, the positions of the fixing holes 40, 46, and 48 (shown in FIG. 6) and the receiving grooves 70 and 80 (shown in FIG. 7) are reflected in the data data2. In this case, the position and attitude of the drilling cylinders 20 (shown in FIG. 6) may be reflected together in the data data2 based on the data data3 obtained through the implant planning.

Next, a drilling template is manufactured based on the data data2 (S7), and the drilling tube 30 (shown in FIG. 6) is mounted on the drilling cylinder 20 (shown in FIG. 6) formed in the drilling template.

Next, a hole is formed in the alveolar bone of the patient with a drill through the drilling cylinder 20 (shown in FIG. 6) and the drilling tube 30 (shown in FIG. 6).

Hereinafter, various embodiments of the disclosure according to FIGS. 6 to 8 will be described.

(1) A drilling template for implant procedures comprising a fixing hole, the first fixing member fixed to the alveolar bone and a second fixing member fixed to the first fixing member through the fixing hole. As a result, the drilling template can be securely fixed to the alveolar bone.

(2) a drilling template for an implant procedure having a receiving groove and having a fixing member received in the receiving groove. Thereby, the drilling template can be tightly fixed to the alveolar bone.

According to one implantation drilling template according to the present disclosure, it is advantageous to position the drilling template in the alveolar bone.

According to another implant drilling template according to the present disclosure, it is possible to improve the error between the implant planning and the implant procedure.

9 is a view showing an example of a drilling template (guide) for the implant procedure according to the present disclosure, the drilling template is a body 10, a drilling cylinder 20, and a drilling tube 30 to fit the shape of the patient's mouth It includes.

10 is a view showing an example of a cross section of the drilling template for the implant procedure according to the present disclosure, it is described on the premise that the gum 5 is located between the body 10 and the alveolar bone 3 of the drilling template.

A drill 6 with a plunge 7 is used to form a hole 4 in the alveolar bone 3.

The drilling cylinder 20 is formed to have a height depending on the depth of the hole 4 formed in the alveolar bone 3. This is because the bottom of the hole 4 in which the drill 6 is formed in the alveolar bone 3 when the drilling cylinder 20 contacts the upper end of the drilling cylinder 20 with the plunge 7 of the drill 6. It means to have a height (H) that can reach. Thus, the height of the drilling cylinder 20 depends on the depth of the hole 4 formed in the alveolar bone 3 and the length of the drill 6.

For example, when the depth of the hole 44 formed in the alveolar bone 3 is 10 mm, the drill 6 may be a 20 mm drill used for drilling 8.5 mm to 11.5 mm, the height of the drilling cylinder 20 It becomes 10 mm and the 20 mm drill 6 can form the hole 44 of 10 mm depth in the alveolar bone 3.

A plurality of drilling cylinders 20 may be formed in the body 10, and the plurality of

drilling cylinders

20, 22, and 24 correspond to each of the

holes

4, 42, and 44 formed in the alveolar bone 3, respectively. Each has a height that depends on the desired depth to be formed.

For example, when the depths of the plurality of

holes

4, 42, 44 in the alveolar bone 3 are formed in 5 mm, 7 mm, and 10 mm, respectively, the drill 6 is a 20 mm drill used for 8.5 mm to 11.5 mm drilling. It can be used, the height of each of the plurality of

drilling cylinders

20, 22, 24 is 15mm, 13mm, 10mm to form a plurality of holes (4, 42, 44).

Here, the plurality of

drilling cylinders

20, 22, 24 are gently formed such that the body 10 reaches the upper ends of the drilling cylinder 20 and the drilling cylinder 24, and the drilling cylinder 20 and the drilling cylinder 22. In the meantime, the body 10 between the drilling cylinder 22 and the drilling cylinder 24 is formed to a thickness such that it reaches the upper end of each of the plurality of

drilling cylinders

20, 22, 24 to have a height H. May be

The drilling tube 30 is mounted to the drilling cylinder 20. The drilling tube 30 has an outer diameter that matches the inner diameter of the drilling cylinder 20, and an inner diameter that matches the outer diameter of the drill 6 is inserted into the drilling cylinder 20 so that the drill 6 drills into the alveolar bone 3. When forming, it is possible to hold the posture of the drill (6). The inner diameter of the drilling tube 30 may vary depending on the outer diameter of the drill 6. On the other hand, the drilling tube 30 preferably has a mark that can identify the type (for example, the length of the drill) of the drill (6). Accordingly, by using the drill identified by the drilling tube 30 in the implant procedure, it is possible to improve the formation of holes of the wrong depth by mistake.

11 is a view showing an example of a method of manufacturing a drilling template for implant surgery according to the present disclosure.

First, a denture is produced (S1).

Next, the denture is placed on the patient's alveolar bone 3 (see FIG. 10) and then imaged to obtain data data1 (S2). For example, imaging may be done by CT.

Next, the image is captured to obtain data data2 (S3).

Next, the data (data1, 2, for example, image data) obtained through the imaging is matched to create the implant planning data (data3) (S4). Here, the depth of the hole 4 (see FIG. 10) formed in the alveolar bone 3 (see FIG. 10) is planned, and the length of the drill 6 (see FIG. 10) and the depth of the planned hole 4 (see FIG. 10) are determined. The difference H determines the height H of the drilling cylinder 20 (see FIG. 10).

For example, in order to form a hole of 10 mm depth, the height of the drilling cylinder 20 (see FIG. 10) may be 10 mm when a 20 mm drill used for 8.5 mm to 11.5 mm drilling is used, and a 11.5 mm to 15 mm drilling If a 23 mm drill is used for the drilling cylinder 20 (see FIG. 10), the height may be 13 mm.

Next, the data data2 is processed to reflect the height H of the drilling cylinder 20 (see FIG. 10) based on the data data3 obtained through implant planning (S5). In other words, the height H of the drilling cylinder 20 (see FIG. 10) is reflected in the data data2.

Next, a drilling template is manufactured based on the data data2 (S6), and the drilling tube 30 (see FIG. 9) is mounted on the drilling cylinder 20 (see FIG. 9) formed in the drilling template.

Next, after positioning the drilling template on the patient's alveolar bone 3 (see FIG. 10), drill 6 (see FIG. 10) through the drilling cylinder 20 (see FIG. 10) and the drilling tube 30 (see FIG. 10). As a result, a hole is formed in the patient's alveolar bone 3 (see FIG.

In the following, various embodiments of the disclosure according to FIGS. 9 to 11 are described.

Each guide hole 20 is integrally formed by the connecting portion 40.

FIG. 13 is a view illustrating an example of a marker that forms part of a surgical guide assembly according to the present disclosure, and shows that the marker 50 is coupled to the tooth 60. The marker 50 is made of a material having such a property because it should be distinguishable from a medical image (eg, CT image) of the tooth 60. For example, it may be made of titanium. However, any material may be used as long as it can be identified by the medical imaging apparatus. Preferably, the marker 50 is coupled to the tooth 60 and has a body 51 on which the connector 30 is positioned and fixed and a reference point 52 which serves as a reference for identification. By providing the reference point 52, it is possible to specify the position of the marker 50 more accurately than when using the body 51 as a reference for identification. Therefore, only the reference point 52 may be made of a material that can be identified by the medical imaging apparatus. On the other hand, since the marker 50 has different intensity on the data image, the marker 50 may be distinguished by designating this intensity.

Next, a method of manufacturing and using a surgical guide according to the present disclosure will be described by taking an example of a drilling guide for implant surgery.

First, as shown in FIG. 13, the marker 50 is attached to the tooth 60, and then the patient is photographed with CT equipment to obtain image data.

Next, as illustrated in FIG. 3, implant planning is performed using image data.

Finally, the surgical guide 10 is manufactured through the RP equipment from the information of the guide hole corresponding to the position of the marker 50 and the planned information (position of the implant). Since the position of the marker 50 is shown on the image data, by specifying the position of each marker 50 (exactly by specifying the reference point 52), the spatial position of the marker 50 can be determined, Based on this, it is possible to manufacture the surgical guide 10 by determining the spatial position of the connector 30 and the guide hole 20.

The surgical guide 10 thus manufactured is positioned on the marker 50 of the patient through the connector 30, and then a hole for implant placement can be formed using a drill.

The connector 30 and the marker 50 may be shape-bonded, or an adhesive may be used for more secure fixing. The shape of the connector 30 is not limited to an open ring, but may be a closed ring. The shape of the marker 50 and the connector 30 may have any modification as long as the marker 50 can function as a criterion of identification and the connector 30 can be combined with the marker 50.

Hereinafter, various embodiments of the disclosure according to FIGS. 12 and 13 will be described.

(1) Surgical guide and surgical guide assembly that can be accurately positioned on the body using a marker.

(2) Surgical guide and surgical guide assembly that can be accurately fixed to the body using a marker.

(3) Surgical guides and surgical guide assemblies that do not require fastening pins as in FIG.

(4) Surgical guides and surgical guide assemblies that do not require separate denture fabrication to distinguish them from the body.

(5) Surgical guides and surgical guide assemblies that eliminate unnecessary and inaccurate contact of the surgical guide with the body through positioning and fixation through markers and connectors. Only the connectors and / or functional elements may be configured to contact the body (not necessarily contacting the body, but only including contacting markers attached to the body).

(6) Surgical guides and surgical guide assemblies that eliminate errors due to matching between image data for the denture and image data for the body.

14 is a view for explaining an example of the process of designing the implant placement according to the present disclosure, the depth (H) of the hole. Taking into account the length of the drill (D), the length of the implant mount (M) and the height of the guide hole (G), a procedure for determining the height of the drilling spacer (DS) and / or the height of the implant mount spacer (MS) is presented. have.

For example, on the screen as shown in FIG. 2, when three implants 170A, 170B and 170C are designed to have outer diameters of 3 mm, 2 mm and 2 mm, and lengths of 6 mm, 5 mm and 3 mm, respectively, In the process of designing a guide as shown in FIG. 3, when designing a guide having a guide hole of a constant height, the height G of the guide hole is set to 9 mm, and the length D of the drill to be used is 16 mm, 14 mm, and If it is designated as 14 mm, the height DS of each of the drilling spacers is calculated as [D-H-G] and is determined as 1 mm, 0 mm and 2 mm. Also, if the length M of the implant mount to be used is set to 9 mm equal to the height G of the guide hole, the implant mount space becomes unnecessary.

On the other hand, in the case of designing guides having guide holes of different heights, if the height G of the guide holes is designed to be 10 mm, 9 mm, and 11 mm, respectively, the drilling spacers are not required in the drilling process, and the length of the implant mount to be used If M) is designated as 13 mm, 11 mm and 11 mm mm, respectively, the height of each of the implant mount spacers MS is calculated as [M-G] and set to 3 mm, 2 mm and 0 mm.

Based on this calculation, the heights of the drilling spacer and the implant placement spacer are determined, and the inner diameter of the guide hole, the inner diameter of the drilling spacer, and the inner diameter of the implant mount spacer can be designed according to the outer diameter of the implant.

FIG. 15 is a view for explaining an example of a preferred method for manufacturing guides and spacers from implant planning according to the present disclosure. First, using a medical imaging apparatus such as CT equipment or MRI equipment from bone 110, FIG. The bone image 111 is acquired. The bone image 112 is an enlarged image of the bone image 111. Next, a guide image 101 is formed that follows the cross-sectional shape of the bone image 112, and a functional element 121, such as the guide hole 120, is planned here. At this time, not only the functional element 121 corresponding to the guide hole 120 but also the functional element 161 corresponding to the spacer 160 designed according to the present disclosure are formed together. The information about the guide image 101 on which the
