Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a drill 100 for an implant procedure according to an embodiment of the present invention, Figure 2 is a side view of the drill 100 for the implant procedure shown in FIG. Hereinafter, the drill 100 for the implant operation according to the present embodiment will be described with reference to this.

As shown in Figure 1 and 2, the drill 100 for the implant procedure according to the present embodiment includes a drill body part 200 and a drill connection part 300 having a first blade portion 250 In addition, the drill body part 200 may be provided with a plurality of through holes 220 penetrated in an internal groove 210 and a twisted shape.

The drill body part 200 is a member including a first blade portion 250 that plays an important role in the implant treatment drill 100 to drill a groove in the alveolar bone, and becomes a main body of the implant treatment drill 100. to be.

Here, the inner groove 210 may be formed in the drill body part 200. The inner groove 210 communicates with the outside in the direction in which the first blade portion 250 is located, that is, may be open in the direction of the first blade portion 250 (the right side is open in FIG. 1). In addition, the inner groove 210 may form a predetermined space in the interior of the drill body part 200, the space of the alveolar bone generated when the first blade portion 250 drills a groove in the alveolar bone can be accommodated. have. Therefore, the alveolar bone fragments are left on the gums of a person and excessive heat is generated when puncturing, thereby preventing the necrosis of the alveolar bone.

The through hole 220 may be formed through the outer circumferential surface of the drill body part 200. The through-hole 220 according to the present embodiment may be formed in a plurality of long along the longitudinal direction of the drill body part 200, so as to minimize the effect on other parts other than the cutting area while improving the cutting function of the alveolar bone. It may elongate in a twisted shape (ie in a twisted shape). In other words, one end 221 of the through-hole 220 (area close to the drill connection part 300) and the other end 222 (area close to the first blade part 250) are twisted without being connected in a straight line to smooth the curve. Can be connected. In addition, the through hole 220 may pass through an outer circumferential surface of the drill body part 200 and may communicate with an internal groove 210 formed in the drill body part 200. Therefore, a piece of alveolar bone that is cut and moved along the side of the drill body part 200 may enter the inner groove 210 through the through hole 220.

The outer circumferential surface of the drill body part 200 may be divided into a plurality of leg regions 230 by the plurality of through holes 220. The leg region 230 may have a shape connected to each other at the upper end 231 and the lower end 232 while being spaced apart from each other by the through hole 220. In addition, since the through-hole 220 is penetrated in a twisted shape, the leg area 230 may also extend in a twisted shape. On the other hand, the second blade portion 240 may be included on both sides of the leg region 230, that is, around both sides of the through hole 220. The second blade portion 240 may help to crush the alveolar bone by helping the first blade portion 250, and when the first blade portion 250 gradually progresses deeply while grinding the alveolar bone, the side of the alveolar bone is crushed to crush the alveolar bone. This can make the process of drilling grooves easier. In addition, the second blade portion 240 may be implemented to have a shape that is bent toward the inside from the leg region 230 to form a sharp end. The second blade portion 240 may be provided on both sides of the leg region 230 (that is, both sides of the periphery region of the through hole 220), or may be provided only on one side of both sides.

At this time, as shown in FIG. 2, when the drill 100 for the implant procedure is arranged such that the first blade portion 250 is directed upward, one end 221 of the through hole 220 is biased to the left side and the other end ( 222 may be biased to the right. Therefore, when viewed from FIG. 2, the leg area 230 in which the second blade part 240 is positioned may also have a twisted shape that is biased from the left to the right while pointing upward. This is associated with the rotational direction of the implant 100 for drilling, it is assumed in the present embodiment that the drill 100 for implant surgery in Figure 1 is rotated in the counterclockwise direction, the second blade portion 240 in FIG. The upper side of the) is set to make efficient cutting by making the alveolar bone first. If the implant 100 is rotated in the clockwise direction, unlike in FIG. 2, one end 221 of the through hole 220 may be set to the right side and the other end 222 may be set to the left side. That is, the side surface of the alveolar bone may be smoothly crushed from the other end 222 of the through hole 220 toward one end 221 according to the rotation direction of the drill 100 for the implant procedure.

Meanwhile, in the present embodiment, three through holes 220 may be configured. If the number of the through holes 220 is greater than three, the thickness of the leg region 230 becomes too thin and the workability is reduced, and the alveolar bone fragments inside the inner groove 210 are discharged to the outside by many through holes 220. Problems may arise. In addition, when the number of the through holes 220 is less than three, the number of the second blade parts 240 may be reduced, and thus the processing of the alveolar bone side may be insufficient. Thus, the inventors of the present invention derived a suitable for securing the workability of the drill 100 for the implant procedure while smoothing the side of the alveolar bone when the number of through holes 220 is three.

3 is an enlarged view of a portion A shown in FIG. 2, and FIG. 4 is a top view showing the arrangement of the blade regions 251 of the drill 100 for the implant procedure shown in FIG. 3. Hereinafter, the first blade portion 250 of the drill body part 200 according to the present embodiment will be described with reference to FIGS. 1 to 4.

Referring to FIG. 2, the first blade portion 250 is a member for cutting or crushing the alveolar bone to form a groove, and includes a connection area 252 connecting the plurality of blade areas 251 and the blade areas 251. can do. Here, in the region that plays a main role of alveolar bone grinding, the blade region 251 may be longer than the connection region 252 to the outside (upper side). In this case, the connection area 252 may also have a cutting and grinding function, but its role may be smaller than that of the extended blade area 251. In addition, the blade region 251 and the connection region 252 may be provided with a sharp end is bent toward the inside in order to effectively crush the alveolar bone.

In addition, as shown in FIG. 3, in order to sharpen the blade area 251, the heights of both ends of the blade area 251 may be different from each other, and the height of one side 251a (the right in the drawing) is the other side 251b; In the upper left), one side 231a can be made sharper. At this time, which of the two sides is to be higher to be associated with the direction of rotation of the implant 100 drill, in this embodiment the drill 100 for the implant procedure in Figure 1 is rotated counterclockwise In FIG. 3, it is assumed that one side 231a of the blade region 251 contacts the alveolar bone first than the other side 231b, and the height of one side 231a may be higher. If the implant 100 is rotated in the clockwise direction, it may be desirable to increase the height of the other side 231b of the blade region 251 compared to the one side 231a. That is, it can be seen that it is desirable to increase the height of the portion that first contact the alveolar bone according to the rotation direction of the drill 100 for the implant procedure. In addition, the height difference of the blade area 251 may also be associated with the twisted shape of the through hole 220. Specifically, both sides of the blade region 251 has one side 231a and the other side 231b having different heights, and one end 221 far from the first blade portion 250 of the through hole 220 is the blade region. The other end 222 which is biased toward the other side 231b of 251 and the other end 222 adjacent to the first blade part 250 of the through hole 220 may be set to be biased toward one side 231a of the blade area 251. In this case, while the alveolar bone is effectively crushed by the first blade unit 250 and the second blade unit 240, a negative effect on the alveolar bone area that should not be crushed can be minimized.

Meanwhile, the implant 100 for implant surgery according to the present embodiment may include three blade regions 251. This can be seen as an optimized value, if the number is less than three may not be suitable for grinding the alveolar bone enough, if the number is more than three, the grinding effect is significantly greater than the effort to process the first blade portion 250 This may be because it is not stretched. Therefore, the inventor of the present invention derives three as the most suitable number of blade areas 251. In this case, the blade area 251 may be positioned at intervals of 120 ° with respect to the center as shown in FIG. 4 so that the grinding according to the first blade part 250 is not biased to a specific area.

On the other hand, as described above the salping drill body part 200 is an optimized structure for forming a groove in the alveolar bone, through the drill body part 200 according to the present embodiment to form a groove very easily with a small force on the alveolar bone. It is possible to form a convenient groove without a single drill 100, convenient and error-free, without having to replace the drill can reduce the time for drilling the groove.

5 is an exploded perspective view of the drill 100 for the implant procedure shown in FIG. Hereinafter, with reference to this it will be described with respect to the drill connection part 300 of the drill 100 for the implant procedure according to this embodiment.

The drill connecting part 300 may be located in an opposite direction of the first blade part 250 as a part for connecting the drill body part 200 to a tool such as a dental hand piece. . In addition, the drill connection part 300 may be fixed to the handpiece, the fixing groove 310 may be formed to receive the driving force of the handpiece to transmit the driving force to the drill body part 200. At this time, when the dental handpiece is driven, the driving force may be transmitted to the drill body part 200 through the drill connection part 300, and accordingly, the drill connection part 300 and the drill body part 200 are rotated. The alveolar bone may be pulverized by the first blade portion 250 or the second blade portion 240.

Meanwhile, as shown in FIG. 5, the drill connection part 300 may be detachably coupled to the drill body part 200. Such detachable coupling may be possible, for example, by screwing, for example, the drill body part 200 includes a first coupling region 260 including a thread on an outer surface thereof and the drill connection part 300 has an inner surface. In the case of including a second coupling region 320 including a screw thread, the drill body part 200 and the drill connection part 300 by screwing the first coupling region 260 and the second coupling region 320. Can be detachably combined.

When the drill connection part 300 and the drill body part 200 are separable as described above, washing and cleaning may be easy. In particular, the implant 100 drill is a part directly in contact with the human body, the body tissue, blood or saliva, etc. during the procedure can be washed and cleaned is important, as in the present embodiment, the drill connection part 300 and the drill body part ( If 200 is separable, cleaning and cleaning after separation may increase the cleanliness of the drill 100 for the implant procedure. In addition, when making the drill 100 for the implant procedure, instead of making one integral member, two separate members are made and then combined, thereby improving workability. Existing integrated products are difficult to form the diameter of the drill body part less than 5mm due to difficulties in processing, in particular, it is almost impossible to form less than 3.8mm, but in the case of a detachable product as in this embodiment up to 3.3mm The diameter of the drill body part 200 may be formed. In addition, processing the shape of the through-hole 220 in a twisted shape as in the present embodiment is difficult in processing, this difficulty when machining the drill connecting part 300 and the drill body part 200 in two pieces. Can be solved.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, and the implant drill according to the present invention is not limited thereto. It is clear that modifications and improvements are possible by the knowledgeable.

All modifications and variations of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be apparent from the appended claims.
