4 is a view illustrating an example of a drilling template for an implant procedure according to the present disclosure, wherein the drilling template includes a body 10, a drilling cylinder 20, and a drilling tube 30 that are adapted to a patient's oral cavity shape. .

5 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, and the drilling cylinder 20 The height is 10 mm so that the 20 mm drill 6 can form a hole 44 having a depth of 10 mm 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 during the implant procedure, it is possible to improve the formation of holes of the wrong depth by mistake.
