Description

Maxillary sinus drill drill tool

The present invention relates to a drill tool for maxillary sinus elevation, and more particularly, the drilling of the alveolar bone for implantation proceeds sequentially by a plurality of drills to form a solid hole in the alveolar bone, and also to the maxillary sinus lining The present invention relates to a drilling tool for the maxillary sinus, which can more stably work on the maxillary sinus and prevent the damaging of the lining of the maxillary sinus.

Implant (implant) refers to a substitute that is originally restored when human tissue is lost, but in the dentist refers to the implantation of artificial teeth. In order to replace the lost tooth root (tooth root), the tooth root made of titanium (titanium), etc., which is not rejected by the human body, is planted in the alveolar bone where the tooth falls out, and the artificial tooth is fixed to restore the function of the tooth.

In the case of general prosthetics or dentures, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they have the same function or shape as natural teeth and do not cause tooth decay.

Implants also enhance the function of dentures and improve the aesthetic aspects of dental prosthetic restorations, as well as in single brace restorations, as well as in partial and complete teeth. Furthermore, it disperses excessive stress on surrounding supportive bone tissue and helps stabilize teeth.

On the other hand, the implant success rate in the maxillary posterior part is known to be relatively low compared to the success rate in other parts, for example, the mandibular posterior part during such implantation procedure. This is because it is not easy to implant.

In other words, the maxillary sinus, which is located between the upper molar and, more precisely, the upper molar and the side of the nose, is a space surrounded by the mucous membrane and expands downward when the tooth is lost physiologically. As a result of the bone absorption, the amount of bone that can be implanted is insufficient due to the downward expansion, which makes it difficult to implant the implant into the maxillary posterior molar.

In this case, after forming a space by elevating the maxillary sinus lining, a bone graft material is implanted in the secured space, and implantation is implanted therein. Such methods include a vertical approach and a lateral approach.

First, the vertical approach is a method of securing a certain amount of residual bone in the implant site, and tapping the maxilla several times with a device called a chisel and hammer-shaped osteotomes to prevent damage to the maxillary sinus lining. Then, a little bit of bone graft material through the hole.

However, when using such a vertical approach, because the maxillary sinus lining cannot be seen directly during the procedure, the procedure takes a long time because the operation is performed very carefully while checking the process by X-rays.

In addition, the lateral approach is a method when the remaining bone of the implant site is very insufficient, forming a hole on the side of the maxillary sinus, elevating the lining of the maxillary sinus, and transplanting a bone graft material through the hole. By the way, this method has the advantage that the procedure can be faster than the vertical approach, there is a concern that the edema may occur in the treatment site as well as the operation itself is difficult.

Therefore, in order to solve these problems, recently, maxillary sinus elevation using a general implant drill has been studied, and furthermore, it is actually applied.

By the way, the maxillary sinus elevation using such a general implant drill has the advantage that the maxillary perforation can be easily and quickly. Damage to the inner lining of the maxillary sinus may occur due to contact with the inner lining, which may cause a problem of failing to accurately elevate the lining of the maxillary sinus and not allowing sufficient space for implant implantation.

Therefore, the situation is required to develop a new drill structure for the maxillary sinus lining that can not only accurately form a hole in the alveolar bone but also to raise the maxillary sinus lining without damage.

It is an object of the present invention, the perforation of the alveolar bone for the implant procedure is progressed sequentially by a plurality of drills to form a solid hole in the alveolar bone, and also to make the elevation of the maxillary sinus lining more stable, the maxillary sinus lining This damage can be prevented, thereby providing a drill tool for the maxillary sinus, which makes the implant procedure more reliable.

According to the present invention, the perforation of the alveolar bone for implantation proceeds sequentially by a plurality of drills to form a solid hole in the alveolar bone, and also to make the elevation of the maxillary sinus lining more stable. Damage can be prevented, which makes the implant procedure more reliable.

In one embodiment of the present invention, the maxillary sinus levitation drill tool, the guide drill 100 and the guide drill 100, which not only checks the position of the implant (not shown) to be placed in the alveolar bone 5 but primarily executes a drilling operation. Drill into the hole of the alveolar bone 5 drilled a predetermined depth to drill the alveolar bone 5 to a portion adjacent to the maxillary sinus lining 3 located inside the alveolar bone 5, but can control the drilling depth. A cutting drill for cutting the inner portion of the alveolar bone 5 until it is introduced into the hole of the alveolar bone 5 drilled by the drilling drill 200 and the upper surface thereof is in contact with the maxillary sinus lining 3. The remaining portion of the alveolar bone 5 generated by the shape of the cutting drill 300, as well as raising the maxillary sinus lining 3 exposed by the cutting drill 300 in the direction away from the alveolar bone. Maxillary sinus elevation mechanism 400 for removing 5c (see FIG. 8) and maxilla A press drill 500 for filling the bone graft material 8 (see FIG. 10) into a space where the inner film 3 is formed on an elevated surface and uniformly pressurizing the bone graft material between the maxillary sinus lining 3 and the alveolar bone 5. It includes.

Firstly drill the alveolar bone 5 shallowly using the guide drill 100 to indicate the center of the portion to be drilled (see FIG. 2), and then to the portion adjacent to the maxillary sinus lining 3 by the drilling drill 200. After drilling 5 (see FIG. 5), the alveolar bone 5 is drilled (see FIG. 11) until it comes into contact with the maxillary sinus lining 3 by the cutting drill 300, and then the maxillary sinus elevation mechanism. After elevating the maxillary sinus lining 3 using 400 (see FIG. 13), insert the bone graft material 8 into the space formed by the maxillary sinus lining operation and then use the drill 500 for pressure. The implant 8 is pressed between the alveolar bone 5 and the maxillary sinus lining 3 (see FIG. 15).

Hereinafter, each configuration will be described in detail.

First, the guide drill 100 of the maxillary sinus levitation drill tool according to an embodiment of the present invention, as shown in Figures 1 and 2, is provided in a hollow cylindrical shape and a regular cutter 111 at the upper end The guide body 110 and the guide body 110, which is provided to stand in the inner center of the guide body 110 is provided to protrude more than the cutter 111 of the guide body 110 to point the center of the alveolar bone 5 to be punctured (point) The point portion 120 and the guide rod 130 is formed extending from the lower end of the guide body 110 and the connection groove 131 is formed at the end. Here, the shaft center of the point portion 120 and the virtual shaft center of the guide body 110 substantially coincide so that the tip portion of the point portion 120 may accurately point the center of the alveolar bone 5 to be drilled.

The serrated cutter 111 provided at the upper end of the guide body 110 forms a shallow hole primarily in the alveolar bone 5 in which the implant is to be placed. For example, when the length from the surface of the alveolar bone 5 to the maxillary sinus lining 3 is approximately 5 mm, the guide body 110 performs a drilling operation to a depth of about 2 mm from the surface of the alveolar bone 5. At this time, the point portion 120 provided in the inner center portion of the guide body 110 marks the center of the alveolar bone 5 to be perforated.

That is, after performing the drilling operation to the predetermined depth with the guide drill 100, the guide drill 100 is removed from the alveolar bone 5, and the center of the hole of the perforated alveolar bone 5 is indicated by the point portion 120. The points are marked. Therefore, the punched shape of the alveolar bone 5 can be clearly confirmed after the punching operation of the guide drill 100, and furthermore, the drilling drill 200 to be described later can be positioned at the correct position, and then the punching operation can be executed.

In addition, the side walls of the guide body 110, as shown in Figures 1 and 2, the discharge hole 212 is formed. By inserting a separate mechanism (not shown) into the discharge hole (212) after the drilling operation, the alveolar bone (5), etc., which may remain inside the guide body 110 during the drilling operation of the alveolar bone (5) to the outside It can be taken out easily. In addition, by providing the saline solution directly to the discharge hole 212, the drilling operation may proceed smoothly.

As shown in FIG. 1, the guide rod 130 is provided with a connecting groove 131 at the end of which a handpiece (not shown) for detachably coupling is detachably coupled to the guide rod 130. In addition, a through hole (not shown) communicating with the inner space of the guide body 110 may be formed inside the guide rod 130. When the through-hole is formed in the guide rod 130, the saline solution can be provided to the inside of the guide rod 130 can be carried out a more smooth drilling operation.

As described above, the guide drill 100 of the present embodiment is described later by accurately displaying the center of the alveolar bone 5 to be punctured by the point portion 120 while performing the drilling operation on the alveolar bone 5 having the implant placed therein. To be drilled for drilling 200 to execute the drilling operation at the correct position.

On the other hand, the drilling drill 200 of the maxillary sinus elevation drill tool according to an embodiment of the present invention, as a drill for drilling the alveolar bone (5, 5) located in the upper jaw or lower jaw, such as in Figures 3 to 8 As shown in the figure, a hollow cylindrical shape is provided and a cutter 211 is provided for drilling the alveolar bone 5 at one end facing the alveolar bone 5 and a through hole 213 is formed at the other end thereof. Body 210 and the drilling rod 230 is coupled to the through-hole 213 of the drilling body 210 to be movable along the inside of the drilling body 210 to adjust the depth of drilling of the alveolar bone 5, and drilling It includes a position fixing unit 250 is coupled to the drilling body 210 to be movable along the thickness direction of the side wall of the body 210 to fix the position of the drilling rod 230 relative to the drilling body 210.

3 and 4, the perforated body 210 is provided in a hollow cylindrical shape with an open upper portion, a sawtooth cutter 211 is formed at the upper end portion and a through hole formed through the lower portion ( 213 is formed.

In addition, in the inner central region of the perforated body 210, there is a receiving portion 217 for accommodating the bone fragments 5a (see FIG. 5) of the alveolar bone, that is, the alveolar bone portion 5a, generated during the drilling of the alveolar bone 5. It is formed along the depth direction, the discharge hole 219 communicating with the receiving portion 217 is formed through the side wall of the perforated body 210 through the alveolar bone portion (5a) generated during the drilling operation of the alveolar bone (5) Can be easily discharged. However, in the present embodiment, the alveolar bone portion 5a generated during the drilling operation of the alveolar bone 5 has been described above to be removed through the discharge hole 219, but the receiving portion 217 using a separate mechanism (not shown). The alveolar bone portion 5a may be removed through.

The perforated body 210 rotates substantially simultaneously with the perforated rod 230 when the perforated rod 230, which will be described later, is rotated by the rotational force provided from the handpiece (not shown), and moves toward the inside of the alveolar bone 5. As a result, a hole for implantation (not shown) is formed in the alveolar bone 5.

For example, when the thickness of the alveolar bone 5 to be drilled is about 5 mm, that is, when the length of the fixture (not shown) to be implanted is about 5 mm, the above-described guide drill 100 (see FIG. 1). It can be perforated by about 2mm, and by the cutter 211 of the perforated body 210 of the present embodiment can be perforated up to 5mm from the surface of the alveolar bone (5).

Therefore, prior to drilling the alveolar bone 5, X-ray imaging or the like may be preceded to confirm the thickness of the alveolar bone 5 and the state of the maxillary sinus lining 3 (see FIG. 5). The drilling depth of each drill should be set via the information obtained by.

However, according to the related art, since it is not easy to precisely puncture to a desired point, it may be troublesome to rework by drilling deeper than the depth to be drilled or shallower than the depth to be drilled.

Therefore, in order to solve this problem, the drilling drill 200 of the present embodiment is provided with a drilling rod 230 to be drilled by the desired drilling depth by moving in the longitudinal direction from the inside of the drilling body 210. .

As shown in FIGS. 3 and 4, the drilling rod 230 of the present embodiment is movable relative to the drilling body 210 along the longitudinal direction from the inside of the drilling body 210 to the drilling body 210. It can be easily adjusted for the position, it is also fixed by the position fixing unit 250 to be described later to make the punching work when the punching work for the alveolar bone (5).

The perforated rod 230 is a hole corresponding to the length of the fixture by allowing the perforated body 210 to advance only a predetermined depth of the alveolar bone 5, that is, a predetermined depth by the perforated rod 230. 5) to be formed.

In more detail, the perforated rod 230 is disposed relative to the perforated body 210 such that the distal end of the perforated rod 230 is approximately 2 mm apart from the distal end of the perforated body 210, that is, the upper end of the cutter 211. After moving and fixing, and then performing a drilling operation for the alveolar bone (5), the alveolar bone (5) is perforated by a depth of 2mm by the cutter 211 of the perforated body (210). In addition, when the depth of the alveolar bone 5 to be drilled is thicker, for example, 3 mm, the perforated rod 230 is moved relative to the perforated body 210 so that the tip portion of the perforated rod 230 and the perforated body 210 are moved. Fixing the perforated rod 230 to the perforated body 210 so that the front end portion is 3mm apart and can then perforate the alveolar bone 5 by 3 mm.

That is, since the punching rod 230 is relatively movable with respect to the punching body 210, the position of the punching rod 230 with respect to the punching body 210 is adjusted according to the set drilling depth, and the punching body ( By fixing the position of the punching rod 230 with respect to 210 to execute the operation it is possible to easily and firmly execute the drilling operation to a predetermined depth.

To this end, as shown in Figure 4, the outer circumferential surface of the punching rod 230, the male screw portion for advancing the punching rod 230 in the inner direction of the punching body 210 or retracted in the opposite direction by rotation ( 231 is formed. In addition, a female thread part 214 corresponding to the male thread part 231 of the punching rod 230 is formed in the through hole 213 formed through the other end of the punching body 210.

Accordingly, when the drilling rod 230 is rotated in the forward direction, the drilling rod 230 is advanced toward the inside of the drilling body 210. On the contrary, when the drilling rod 230 is rotated in the reverse direction, the drilling rod 230 is connected to the drilling body 210. To retreat. By this principle, the position of the punching rod 230 with respect to the punching body 210 can be easily adjusted.

On the other hand, when the drilling operation of the alveolar bone 5 is in progress, the drilling rod 230 should not move forward or backward or rotate with respect to the drilling body 210. If the perforation rod 230 is not fixed to the perforation body 210 during the perforation operation, perforation of the correct depth may not be performed. That is, when the punching rod 230 advances with respect to the punching body 210 during the punching operation, the hole of the alveolar bone 5 may be formed to have a shallower depth than desired, and the punching rod with respect to the punching body 210 during the punching operation. When 230 is retracted, the hole of the alveolar bone 5 may be formed deeper than the desired depth.

To this end, the position fixing unit 250 for fixing the punching rod 230 is movably coupled to the punching body 210.

Position fixing unit 250 of the present embodiment, the position fixing screw 250 is formed with a male thread 252 on the outer surface to easily fix the position of the drilling rod 230 with respect to the drilling body 210 by the rotation operation Is prepared.

As shown in FIG. 6, the position fixing screw 250 according to the embodiment of the present invention has a puncturing rod 230 along the thickness direction of the sidewall of the puncturing body 210, that is, in a direction crossing the axial direction of the puncturing rod 230. Removably coupled to the installation hole 215 formed through the side wall of the perforated body 210 to be accessible and spaced apart. The position fixing screw 250 may be made of any one of titanium (Titanium) or stainless steel (Stainless Steel).

In the installation hole 215 of the drilling body 210, a female thread 216 corresponding to the male thread 252 of the position fixing screw 250 is formed, thereby rotating the position fixing screw 250 in the forward direction. Then, the position fixing screw 250 is advanced to press one surface of the punching rod 230, that is, the flat portion 233 to be described later, so that the punching rod 230 is fixed to the punching body 210. On the contrary, if the position fixing screw 250 is rotated in the reverse direction, the position fixing unit 250 retreats and thus the pressing force for pressing the punching rod 230 disappears so that the punching rod 230 moves with respect to the punching body 210. It becomes possible.

At this time, when the position fixing unit 250 is in contact with the drilling rod 230, the non-screw portion 233, that is, the flat portion 233 of the present embodiment is provided on the drilling rod 230 so that the pressing force can be effectively transmitted have. The flat portion 233 of the present embodiment is formed by cutting a region of the male screw portion 231, and thus, when the positioning screw 250 presses the flat portion 233 of the perforated rod 230, the perforated rod 230 does not move relative to the perforated body 210, so that it is possible to firmly execute the drilling operation for the alveolar bone (5).

However, in the present embodiment, in order to prevent the movement of the drilling rod 230 with respect to the drilling body 210, the flat portion 233 (see Fig. 7) provided flat as the non-threaded portion 233 of the drilling rod 230 Although the above is applied, but if the processing is easy, as shown in FIG. 8, the groove 233a (groove) instead of the flat portion 233 may be applied to the non-screw portion 233a of the punching rod 230. Since the groove 233a may have an end portion of the positioning screw 250 drawn in a predetermined depth, the fixing force of the drilling rod 230 with respect to the drilling body 210 may be further strengthened.

Position fixing screw 250, as shown in Figure 4, may be tightened or loosened to the perforated body 210 by a hexagon wrench (260). The head of the positioning screw 250 is provided with a wrench groove 254 recessed in a hexagonal shape, and the hexagon wrench 260 is detachably coupled to the wrench groove 254 to fix the positioning screw 250. The positioning screw 250 may be advanced inwardly of the perforated body 210 by rotating in the direction, or the positioning screw 250 may be retracted outward of the perforating body 210 by rotating in the reverse direction.

On the other hand, since the perforated rod 230 is movable along the longitudinal direction of the perforated body 210 from the inside of the perforated body 210, the alveolar bone portion (5a, see Fig. 5) remaining in the perforated body 210 than conventionally Can be easily removed.
