Description

Implant Surgical Drills {DRILL FOR IMPLANT SURGERY}

The present invention relates to a drill for implant surgery, more specifically, the lower body of the main body portion of the drill connected to the handle is configured in a cylindrical shape having a through-hole inside, the main blade and the end of the sharp shape of the main body and It is equipped with vertical and horizontal blades to accurately determine the implant placement position at the initial stage so that the second and third drill operations can be clearly induced later, and the countersinking operation can be carried out at the same time, so that more accurate implants can be performed at a faster time. The present invention relates to an initial drill for implant surgery to allow surgery to be performed so that the prosthesis is finally performed in a stable position.

In general, an implant is an artificial tooth transplant for restoring a lost tooth, and refers to an artificial substitute for planting an artificial tooth most similar to a natural tooth on a portion of the missing tooth without damaging adjacent teeth. Titanium metal, which is non-rejective, adheres to the bone or alveolar bone, and then the prosthesis is fixed thereon when the tooth is lost or lost. Is a kind of dental procedure that restores original function and health.

In the past, for various reasons, a fixed denture is used to make a removable denture, which is usually squeezed and used to recover it, or to replenish missing teeth by slightly grinding the front and rear teeth of the missing tooth. These removable dentures are very inconvenient to use in that they always wear the same dentures as the palm of the hand in the sensitive mouth, and furthermore, they need to be replaced with two healthy side teeth to remove one tooth. There is a concern, and there has been a problem that is not economic.

However, as described above, the use of an implant instead of a denture that has poor fit, pain during use, and a possibility of falling out during meals and conversations can fix the tooth in a fixed way, thereby solving the inevitable discomfort and pain when using the denture. It is possible to avoid seeing the metal ring part of the denture and, first of all, to make the tooth most similar to the natural tooth, so the result is aesthetically much better.

In addition, it restores the function of the missing tooth without damaging adjacent teeth, and restores the function of the missing tooth while preserving the natural tooth in a healthy state without changing the front and rear teeth of the missing tooth. Like the removable dentures, it does not burden the natural teeth at all, so the life of the remaining natural teeth can be long, and the implant is now common in the patient's position.

These implants can be generally divided into three parts: artificial tooth, connecting column, and processed tooth. First, artificial tooth root of excellent biocompatibility is planted in the jaw bone of the missing tooth, which corresponds to the root of natural tooth. After 3 ~ 6 months stabilization period, the bone and artificial tooth are fused to create a sense of unity, and then connected to the oral cavity using the connecting column, and then the processed tooth is fixed to the connecting column again to have the same shape and function as the natural tooth. To reproduce.

Therefore, in order to implant the implant having the characteristics described above, after cutting the gum of the missing tooth, the alveolar bone wrapped therein is deleted according to the size of the implant to create a predetermined groove, the final prosthesis such as a processed tooth It is obvious that the placement position of the implant is most important in determining the position, and it is essential for the dentist to be able to maintain the implant in the intended direction and position initially.

Conventionally, as shown in the drawings, a round drill is used as an initial drill to determine and drill a position for implantation on the surface of the alveolar bone. The planar position may be selectively determined, but the three-dimensional position is not displayed and is 2 mm in advance. Since there is no guide to maintain the position during the next drilling, such as a drill or three mill drill, the side vibration and vibration easily occurs, there has been a inconvenience that must be continuously checked during surgery.

In addition, the intended implant placement position is difficult to maintain due to vibrations and shakes generated during the subsequent drilling, and as a result, the implant is planted in a different position and orientation than the implant intended, thereby determining the position of the final prosthesis. There are many problems.

The present invention has been devised to solve the above problems, the drill is precisely drilled at the implant placement position initially intended by the operator during the implant operation to ensure a clear induction during the subsequent drill work, the countersink process during the initial drill work At the same time, the purpose of the implant placement surgery to be accurately performed in a faster time to achieve a precise prosthesis is finally completed.

In the implant treatment drill consisting of a handle portion; and a body portion which is integrally formed with the handle portion to form a predetermined groove on the alveolar bone for drilling the implant to achieve the above object. The main body is formed in a cylindrical shape having an opening with a bottom open, the peripheral edge of the opening is composed of a basic blade of the form of the thread is repeated, the vertical blade which is formed upright to the opening side in the cylindrical portion of the main body portion To provide a surgical drill and at the same time to provide an implant surgical drill, characterized in that it further comprises a horizontal blade in the form of embossing on the inner upper surface consisting of the body portion.

The initial drill (1) for the implant procedure according to the present invention is a secondary drill using a 2mm drill or a 3rd drill using a 3mm drill in order to accurately delete the alveolar bone of a patient to be implanted in the same shape as the width of the implant. Initially prior to entering the drilling operation, the position of the implant placement point on the surface of the alveolar bone is first drilled at the designated position to create a groove, and then the said position is initially in the intended position until the operation is completed. Based on the groove, subsequent drilling operations, including secondary and tertiary drilling, can be continued.

As shown in FIG. 1 to FIG. 2, the drill for dental surgery according to the present invention (1) has a handle portion 20 and the handle portion 20 which can be easily used by holding the drill 1 large in hand. It is formed integrally with this on one side of the) is formed of the main body portion 10 for directly deleting the alveolar bone at the position where the implant is to be placed, the other side of the handle portion 20 is not connected to the main body portion 10 The drill operation part 21 for operating the main-body part 10 of the said drill 1 is comprised.

Body portion 10 is formed on one side of the handle portion 20 described above to drill a portion of the alveolar bone in order to delete the alveolar bone in accordance with the size of the implant, and according to the degree of drilling the groove in a certain portion of the alveolar bone As a means for forming, the body portion 10 is configured to open the bottom surface which is not adjacent to the handle portion 20 while closing the upper portion adjacent to the handle portion 20 has an opening through the opening It is composed of a cylindrical shape.

And the main body portion 10 is the base blade 11 and the vertical blade (12) of the rigid or sharp shape according to the position and method of being inserted into the alveolar bone and the position and shape of the alveolar bone after cutting the drill (1) and It can be divided into a horizontal blade 13 of the embossed shape, as shown in Figure 2, the bottom surface is open to the edge of the bottom edge of the open bottom of the main body 10 made of a hollow cavity shape is sharp Countersink process is performed in advance by removing the alveolar bone to fit the size of the implant in advance by forming the base blade 11 is made of a repeated thread of, the first drill using the drill (1) according to the present invention and 2mm Using a twist drill and a 3mm twist drill to drill and expand the alveolar bone, a countersink process may have to be carried out in place to accommodate the size of the implant head. It is.

The vertical blade 12 is configured to vertically project from the closed inner predetermined position of the body portion 10 to the outside through the opened bottom surface, and sharply forms the protruding end to be implanted initially intended by the doctor. Drill to fit the placement position to accurately select the position on the surface of the alveolar bone, and to ensure the accurate implant placement to continue to maintain the intended position by absorbing the shaking and vibration as much as possible in the future drilling.

The horizontal blade 13 is formed by embossing as a whole using a rigid material on the inner surface of the upper surface of the main body portion 10, after removing a portion of the alveolar bone by the base blade 11 and the vertical blade (12). By using the horizontal blade 13 to flatten the upper bone surface from the inside to be able to accurately position the implant.

Hereinafter, the operation and effects of the present invention made as described above will be described in more detail with reference to the drawings in which a process for drilling an implant is shown.

[Step 1] Gum Incision

Figure 3 is a cross-sectional view of the gum in the open state, when the gum (gingival) which is part of the oral mucosa to implant the implant in the patient's gums, the alveolar bone covered by the gum is exposed, to be implanted When the alveolar bone having the same size as the width of the implant (artificial root) is deleted to form a space portion, the implant is implanted into the space portion. In general, it can be seen that the bone surface of the alveolar bone is uneven.

[Step 2] Drilling with Initial Drill

Figure 4 (a) (b) to Figure 6 (a) (b) is a cross-sectional view showing a process for the initial drilling in the alveolar bone prepared by the conventional initial drill round drill and drill according to an embodiment of the present invention ( Figure 1 shows a cross-sectional view showing the process of initial drilling in the alveolar bone using.

When drilling into the intended implant placement position on the alveolar bone using a conventional round drill, the rounded end of the drill frequently causes side vibrations and shakes, resulting in positional errors from the physician's initial intended position. There are many possibilities, and since the implant placement position is finally determined by the groove formed using the round drill, the intended position cannot be maintained even when the next drill is used.

On the other hand, during the initial drilling using the drill 1 according to the present invention, the vertical blade 12 formed in the center of the main body 10 of the drill 1 accurately selects the implantation position of the implant and simultaneously performs lateral vibration. The countersink process can be performed simultaneously by drilling the base blade 11 in advance in the alveolar bone by the width of the implant head, and flattening the surface of the bone by the horizontal blade 13. It can be seen that it can be dissected.

[Step 3] Drilling Using Two Pre-drills

Figure 7 (a) (b) to Figure 8 (a) (b) is a cross-sectional view showing a state of preparing and drilling a 2-mm twist drill in the initial drilling position in the alveolar bone using a conventional initial drill, and one of the present invention It is shown by comparing the cross-sectional view showing a state of preparing and drilling a 2mm twist drill in the initial drilling position in the alveolar bone using the initial drill according to the embodiment.

In the case of using a 2-mm twist drill at the initial drilled position on the alveolar bone using a drill of the same type as a conventional round drill, an error in the intended position due to side vibration and shaking occurred during the initial drill. Due to an error in position, even if the additional 2 mill drills are used to expand the groove of the alveolar bone, the position cannot be maintained due to the same vibration.

On the other hand, by using the drill 1 according to the present invention to precisely initial drilling in the intended position on the alveolar bone, at the position where the groove is created, the vertical blade 13 is drilled and the 2-mm twist drill is formed at the position where the groove is formed. When the alveolar bone is enlarged by using, the side vibration is greatly reduced and the drilling can be done in the correct position by using the pre-drilled groove as a guide.

[Step 4] Drilling Using Three Pre-drills

9 (a) (b) to 11 (a) (b) are cross-sectional views showing a state in which a 3 mm twist drill is prepared and drilled after drilling with a 2 mm twist drill at a position initially drilled with a conventional drill; After drilling with a 2mm twist drill at the initial drilling position by a drill according to an embodiment of the present invention is shown comparing the cross-sectional view showing a state of preparing and drilling a 3mm twist drill.

As in the case of drilling using the 3mm 2mm twist drill of the above step, when using the 2mm drill at the position where the alveolar bone was initially drilled using the existing round drill, and further expanding the groove using 3mm drill While there is a possibility of shaking and error, the use of the drill (1) in accordance with the present invention, when using the 2 mill drills in the initial drilled position on the alveolar bone, and then 3 mill drills are used due to the base As the grooves generated by the grooves and the vertical blades 12 are partially integrated, extended grooves may be formed at the intended positions by preventing shaking and vibration errors due to accurate positioning and guide of the initial drill 1.

[Step 5] Countersink

12 (a) and 13 (a) are cross-sectional views illustrating a state in which a countersink is prepared at a drilled position using a conventional initial drill to expand an upper end portion of a groove. When used, the upper end of the groove does not match the width of the implant, so the alveolar bone is removed and the top of the groove is expanded by using a countersink to fit the width of the groove to the head of the implant.

On the other hand, in the case of using the initial drill (1) according to the present invention, when the initial drill operation, the base blade 11 deletes the alveolar bone according to the size of the implant so that the countersink process is performed at the same time, so that the countersink process can be omitted later. Will be.

[Sixth Step] Tapping Process Using Tapping Drill

14 (a) and 15 (a) are cross-sectional views showing a state in which a tapping is performed using a tapping drill to insert an implant through a countersinking process after drilling by a conventional method, and FIGS. 12 (b) and 13 (13). (b) And Figure 14 (b) is a cross-sectional view showing a state of tapping by using a tapping drill to implant the implant after drilling by the present invention, the countersink in the case of using the initial drill (1) according to the present invention Omitting the process of expanding the upper portion of the groove through the process can be entered directly to the tapping process has the effect of reducing the procedure time.

[Step 7] Implant Placement and Suture

Figure 14 (a) is a cross-sectional view showing a state in which the gum is sealed after the implant is implanted in the position drilled by the conventional method, Figure 13 (b) is an implant in the position drilled using a drill according to the present invention This is a state where the gum is sutured after the implantation. When the implant is implanted after drilling using a conventional drill, the initial implantation position is not possible because the implant is not accurately implanted in the direction and shape intended by the doctor initially. Cannot be maintained and will require continued care and testing after surgery.

On the other hand, when the implant is implanted in the drilled position using the drill (1) of the present invention, the implant can be correctly implanted at the intended position due to the precise positioning of the initial drill and the reduction of vibration and shaking. After the gum closure, the implant procedure is ideally formed, so that the final prosthesis can be positioned at the desired site.

The present invention described above is limited to the above-described embodiments and the accompanying drawings as various substitutions and changes can be made within a range without departing from the technical spirit of the present invention for those of ordinary skill in the art. It is not.

As described above, the present invention is intended to initially form a rigid and sharp edge of the main body of the drill and a vertical blade, and further include a horizontal blade so that accurate drilling can be performed at the implant placement point on the alveolar bone during initial drilling. The position and direction of the cut are maintained until the end of surgery to ensure accurate implant placement, and the countersink process is performed at the same time, allowing the surgery to be completed in a shorter time, resulting in a stable prosthesis. The effect is to provide.
