[ The drill can be pulled through the prosthesis 140 to loosen or tighten the screw 120 and replace the screw 120 and abutment 130 when the screw 120 is released from the fixture 110 It will be used after storage.

In order to manufacture the template 100, the fixture 110 is placed on the jawbone 10, and after 3 months, the template 100 is inspected to produce a master model.

Next, the abutment 130 is connected to the main model and the prosthesis 140 is mounted. Then, the abutment 130 and the prosthesis 140 of the main mold are replicated to produce a working model, and the working model is vacuum- The template 100 is produced.

Here, the contents of the master model and the working model, the fixture 110, the screw 120, the abutment 130, and the prosthesis 140 are well known in the art, and a description thereof will be omitted.

The template 100 may be formed in a transparent manner so that the joint state of the restoration 140 and the normal teeth 30 mounted on the gingival region of the subject can be smoothly checked during use.

The length of the template 100 may vary according to the needs of the user as long as the template 100 can be firmly coupled to the normal teeth 30 and the prosthesis 140.

The inner sleeve 200 is fixed to the through hole 150 formed in the template 100 and is disposed at a position corresponding to the prosthesis 140.

3B, the guide protrusion 210 is removed before the inner sleeve 200 is fixed to the template 100. As shown in FIG.

The inner sleeve 200 serves to prevent the head of the drill from flowing to the left or right when the screw 120 is tightened or loosened by the drill.

The inner sleeve 200 may be formed in a cylindrical shape so as to surround the lower portion of the drill head.

In addition, the inner sleeve 200 can be fixed to the template 100 through the resin, and the inner sleeve 200 can be firmly fixed to the template 100. If the inner sleeve 200 is harmless to the human body, It will be appreciated that a variety of materials may be used for securing the sleeve 200.

Particularly, the inner sleeve 200 is fixed to the template 100 through the resin, and the inner sleeve 200 can be firmly fixed to the template 100, and if the inner sleeve 200 is harmless to the human body It is of course possible to use synthetic resin or various adhesive materials.

After the inner sleeve 200 is fixed to the template 100 through the resin, the prosthesis 140 is attached to the abutment 130 and is inserted into the perforation hole 132 through the abutment 130, The drill can be guided by the inner sleeve 200 while entering the inner sleeve 200 when approaching the screw 120 inside.

The outer sleeve 300 is provided with a support guide protrusion 310 for guiding the flow of the head while allowing the head of the drill to tighten or unscrew the screw 120 to be inserted and supported, And is detachably coupled to the sleeve 200.

Here, the outer sleeve 300 serves to assist the inner sleeve 200 to prevent the drill from flowing to the left and right, and guide the inner sleeve 200 to merely drill.

That is, the outer sleeve 300 plays a role of enabling the drill to be drilled while the head of the drill is advanced into the inside and is supported by the guide jaws 310, while the drill is firmly fixed.

In addition, the outer sleeve 300 may be rotated while being coupled to the inner sleeve 200, and may be fixed at a predetermined position to guide the flow of the head.

That is, since the outer sleeve 300 can be rotated on the inner sleeve 200, the drill head can be rotated in the direction of the outer sleeve 300 and the outer sleeve 300, The user can enter the inner sleeve 200, thereby facilitating the operation of the user.

4A and 4B are views showing an embodiment of an apparatus for forming an implant prosthesis hole according to the present invention.

The outer sleeve 200 is detachably attached to the inner sleeve 200,

The abutment 130 may be damaged or the screw 120 may be damaged and the screw 120 may be damaged during installation and use of the prosthesis 140 by the subject 100. In other words, the template 100, the inner sleeve 200 and the outer sleeve 300, The screw 120 can be loosened or tightened through the prosthesis 140 and the screw 120 and abutment 130 can be replaced when the drill 120 is released from the fixture 110 It will be used after storage.

After the fixture 110 is placed in the jawbone 10 of the implantee and the abutment 130 is mounted to the fixture 110 through the screw 120, the screw 120 or the abutment There is a problem that both the screw 120 and the abutment 130 and the prosthesis 140 must be lifted and replaced when the screw 130 is damaged.

In order to prevent this, the stored template 100, the inner sleeve 200 and the outer sleeve 300 are used.

That is, after placing the template 100 at a predetermined position of the prosthesis 140 and the normal teeth 30, the head 70 of the drill 50 is inserted into the outer sleeve 300 and the inner sleeve 200 And are sequentially entered.

Since the outer sleeve 300 is moved on the inner sleeve 200, the operator can easily place the drill 50 in a convenient position It can be changed.

In this state, the screw 90 extending from the head 70 is drilled and the prosthesis 140 is punctured.

When the screw 90 is pierced through the prosthesis 140, the screw 90 enters the perforation hole 132 of the abutment 130, and the screw 120 can be loosened or re-tightened.

In addition, when the screw 120 is loosened, the abutment 130 can be smoothly replaced, and the prosthesis 140 can be smoothly replaced and reused.

As a result, the drill 50 passes through the template 100, the inner sleeve 200 and the outer sleeve 300, and the screw 120, which allows the fixture 110 and the abutment 130 to be engaged with each other, The screw 120 can be retightened or replaced by passing through the prosthesis 140 in response to the guidance of the outer sleeve 300 and the inner sleeve 200 when the outer sleeve 300 is damaged.

5, when the screw 120 or the abutment 130 is completely replaced, the screw 120 is rotated through the screw 90 of the drill 50 so that the fixture 110 and the abutment 130 are coupled with each other, the prosthesis 140 can be mounted on the abutment 130 and reused.

In addition, the hole formed in the prosthesis 140 by the screw 90 can be used to smoothly use the prosthesis 140 by covering the hole with the same or similar material as the prosthesis 140.

Main model making process (S100)

In the main model making process (S100), the fixture 110 made of metal is placed on the jawbone 10 of the implantee, and then the main model is manufactured by lifting the bone with the impression.

In the main model making process (S100), the fixture 110 is placed on the jaw 10, and the fixture 110 is allowed to be attached to the jaw bone 10 for 3 months. It is to make a master model by drawing a pattern.

Here, the master model can be produced by pouring gypsum into the impression master pattern.

When the main model making process (S100) is completed, the template making process (S200) is performed.

Template making process (S200)

In the template manufacturing process S200, after the main model making process S100 is completed, the main mold 110 is connected to the abutment 130 connected to the fixture 110 through the screw 120, The prosthesis 140 is mounted on the body 130 and then replicated to produce a working pattern and then a template of the template 100 is manufactured.

The template 100 includes a fixture 110 to be fixed to the jaw 10 of a subject to be implanted and a prosthesis 140 to be supported and fixed to the abutment 130 fixed through the screw 120, 140 and the normal teeth 30 arranged side by side.

Here, the contents of the master model and the working model, the fixture 110, the screw 120, the abutment 130, and the prosthesis 140 are well known in the art, and a description thereof will be omitted.

In particular, the template manufacturing process (S200) may be performed by preparing the template by storing the scan information after the teeth are scanned through the oral scanner.

Thus, the scan information for scanning teeth through the oral scanner can be stored and used repeatedly and simply.

In other words, the production of the work model can use various methods according to the convenience of the user, thereby reducing the time and cost consumed in the operation.

When the template manufacturing process (S200) is completed, the inner sleeve fixing process (S300) is performed.

The inner sleeve fixing step (S300)

The inner sleeve fixing step S300 is a step of forming the through hole 150 by drilling the place where the abutment 130 is located in the mold 100 of the template 100 after the template manufacturing step S200 is completed, When the guide protrusion 210 protruding from the inner sleeve 200 disposed in the hole 150 is positioned on the vertical line with the perforation hole 132 formed in the abutment 130, the guide protrusion 210 Is removed and the inner sleeve 200 is fixed on the template 100 through the resin.

The center of the inner sleeve 200 is inserted into the perforation hole 132 of the abutment 130 through the guide protrusion 210 before the prosthesis 140 is mounted on the abutment 130. [ The inner sleeve 200 can be fixed to the template 100 in a state where the outer sleeve 200 is positioned on the same vertical line as the inner sleeve 200.

At this time, the inner sleeve 200 can be fixed to the template 100 through the resin, and the inner sleeve 200 can be firmly fixed to the template 100. If the inner sleeve 200 is harmless to the human body, It will be appreciated that a variety of materials may be used for securing the sleeve 200.

When the inner sleeve fixing step S300 is completed, the outer sleeve coupling step S400 is performed.

The outer sleeve coupling process (S400)

After the inner sleeve fixing step S300 is completed, the outer sleeve coupling step S400 may be performed by inserting the outer sleeve 300, which is detachably coupled to the inner sleeve 200 and is rotatable on the inner sleeve 200, To the sleeve (200).

The outer sleeve coupling step S400 may include a step of guiding the movement of the head 70 while allowing the head 70 of the drill 50 to enter and support the outer sleeve 300, (Step S410) for forming the outer sleeve 310 in the outer sleeve 300 before the outer sleeve 300 is engaged with the inner sleeve 200. [

The outer sleeve 300 can be rotated on the inner sleeve 200 so that the head 70 of the drill 50 can be rotated with the drill 50 disposed in various directions through the guide jaws 310, Can be inserted into the outer sleeve 300 and the inner sleeve 200, thereby facilitating the operation of the user.

As a result, the inner sleeve 200 blocks the head 70 of the drill 50 from flowing to the left and right so that the drilling operation can be performed firmly. The sleeve 200 is assisted to block the head 70 of the drill 50 from flowing to the left and right so that it can be firmly drilled.

In addition, the drill head can be inserted into the outer sleeve 300 and the inner sleeve 200 in a state where the drill is arranged in various directions by the support guide jaws 310, thereby making the operation of the user more robust and smooth .
