Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test block for setting a zero point of an abutment processing apparatus and an abutment processing apparatus using the test block.

The present invention relates to a test block for precisely setting the zero point of a processing apparatus for processing an abutment attached to an implant, and more particularly to a test block using a test block before machining an abutment by a titanium rod The zero point error of the abutment processing apparatus can be measured and corrected.

Generally, the implant is composed of a fixture to be placed in the jawbone, an abutment to be inserted and fixed in the fixture, and a prosthesis to be adhered to cover the upper part of the abutment.

The fixture is placed in the jawbone to serve as a root, and the abutment inserted in the fixture serves to transfer the load acting on the prosthesis to the fixture and the jawbone while fixing the prosthesis to the fixture. The fixture and abutment are sufficient It is made of titanium material which is strong and harmless to the human body.

The abutment, which acts as a landing gear, was used to treat the ready-made parts of the implant as it was in the early days of the implant. However, in order to perform more effective procedures, it was necessary to provide a customized shape according to the patient's oral shape or patient's condition.

Therefore, in recent years, abutments have been designed / manufactured to suit the characteristics of patients. That is, after the abutment is designed to fit the position where the patient is placed in the oral cavity, a cylindrical round bar, which is the material of the abutment, is machined or cut to make an abutment suitable for the characteristics of the patient, A CAD-CAM apparatus or a milling apparatus is used for the abutment processing apparatus.

The abutment processing apparatus fixes a circular rod of titanium material, which is an abutment material, to a predetermined jig, and then applies the data input to the CAD-CAM apparatus or the milling apparatus to process it into a bite.

However, even if the abutment is processed by using the abutment processing apparatus, it is very difficult to obtain the abutment result with satisfactory accuracy.

The reason for this is that in order for the machining accuracy of the abutment to reach the desired level, the setting of the zero point between the fixed position of the jig and the bite for machining must be done very accurately. In the conventional abutment machining apparatus, It is difficult to obtain the abutment result with satisfactory accuracy.

That is, to set the zero point of a byte, the abutment to be manufactured using a round bar is first manufactured, and then the position of the byte is compensated for by the mis-design using the processed result and then processed again. By doing this, you get exactly the zero of the byte.

However, it is practically impossible to set a zero point at a time because it is necessary to accurately set the positions of the three axes of the X axis, Y axis, and Z axis, and it is practically impossible to set a zero point at one time. Set the zero point of the byte while viewing the result.

However, it is difficult to set the zero point by repeating this procedure. It is difficult to set the zero point when it is not an expert, and it takes a long time to set the zero point. In addition, in the process of setting the zero point, a high- There is a problem that it is consumed much.

In addition, since the round bar is a very high-strength titanium material, the number of abutments that can be machined into one byte is limited to several tens. In the test process of setting the zero point of a byte, Because it sets the zero point during machining, there is a problem that the bite is worn before making the actual abutment product.

Even if the zero point setting is set correctly, there is a case where the zero point is set again because the position of the bite is finely twisted in the process of re-installing the jig or repeatedly machining the plural abutments. Since it is difficult to reset the zero point each time, the accuracy and quality of the abutment product may deteriorate.

KR 1020130088242E KR 200303274 Y1

In order to solve the above problems, the present invention provides a test block for confirming error measurement information on the X axis, Y axis, and Z axis, and before the abutment is processed using the round rod of the titanium material It is an object of the present invention to enable quick and accurate setting of a zero point of a byte with respect to a position of a jig.

To achieve the above object, according to one aspect of the present invention, there is provided an apparatus for manufacturing an abutment, comprising a holder, a holder formed on one end of the holder and having an eccentric portion for confirming a direction, And an error measurement solid formed on the other end and processed by the bite of the abutment processing apparatus, wherein the error measurement solid is obtained by confirming the X, Y, Z coordinate errors of the bytes mounted on the abutment processing apparatus The first axis measurement surface, the second axis measurement surface and the third axis measurement surface are formed so that the zero point error of the byte can be confirmed by one zero point test, thereby achieving the object of the present invention.

According to the present invention, it is possible to visually confirm the error measurement information of the bite with respect to the jig of the abutment machining apparatus, accurately measure the error dimension, reset the accurate zero point by only one zero test, Zero point setting time is shortened and even beginners can easily set zero point.

In addition, when setting the zero point of the abutment processing device, the labor force of the laboratory can set the zero point directly so that it is not necessary to refer to the expert engineer and the management cost can be reduced.

In addition, it is possible to prevent an expensive titanium rod from being unnecessarily consumed, and since the bite is not worn during the setting of the zero point, a larger number of abutments can be produced with one byte, which is very economical.

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

As shown in Figs. 1 and 2, the test block 1 of the present invention is mounted on the jig 2 of the abutment processing apparatus, and the test block is mounted on the jig before the abutment is processed, It is possible to measure the coordinate value of the byte 3 with respect to the jig and to correct the zero point error of the byte 3 by performing the processing.

Here, before the abutment used as an actual implant is processed using a round rod of a titanium material, the test is performed on the basis of the test three-dimensional (TD) value inputted to the abutment processing apparatus, Means that the surface of the test block 1, more precisely, the surface of the error measuring three-dimensional object 300 is machined with the tool 3 to check the position of the bite with respect to the jig, thereby correcting the zero point error.

The cutting tool 3 is a term collectively referred to as a cutting tool used in a machine tool such as an abutment machining apparatus, and various cutting tools such as an auger, a chisel, a line, a broach, a milling cutter, a hob and the like can be used.

The material of the test block 1 can be made of a titanium material similar to the material of the round bar for the actual product abutment. More preferably, the test block 1 has a relatively low hardness and a relatively low manufacturing cost It is preferable to fabricate aluminum as a material.

The structure of the test block 1 is composed of a support stand 100, a holder 200 for mounting the jig 2 on the jig 2 of the abutment machining apparatus, an error measuring stamper 300).

The pedestal 100 constitutes the body of the test block 1. The pedestal 100 has a holder 200 at one end and an error measurement stub 300 at the other end.

The holder 200 can be fastened and mounted to the jig 2 of the abutment processing apparatus by bolting and when the holder 200 is machined by the bite 3 in the state that it is fastened to the jig 2 The holder 200 may be provided with a directional eccentric portion 210 so as to prevent idling while maintaining a firmly fixed state.

At this time, the eccentric part 210 may be formed with a D cut 212 having one end cut off, or a position fixing or direction confirming groove 214.

The error measuring three-dimensional object 300 is a three-dimensional shape portion in which actual processing is performed when testing using the bite 3. The three-dimensional structure of the error measurement is the X, Y and Z coordinate error of the bite mounted on the abutment processing apparatus A first axis measuring surface 310, a second axis measuring surface 320, and a third axis measuring surface 330 for confirming each of the first axis measuring surface 310 and the second axis measuring surface 320, respectively.

That is, the first axis measuring surface 310, the second axis measuring surface 320, and the third axis measuring surface 330 are for measuring coordinate values of different axes, The second axis measuring surface 320 is for measuring the error value with respect to the Y axis coordinate of the byte 3 and the second axis measuring surface 320 is for measuring the error value with respect to the X axis coordinate of the byte 3, (330) may be for measuring the error value with respect to the Z-axis coordinate of the byte (3).

The first axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 are symmetrically arranged on both sides of the error measuring three-dimensional object 300, You can get the +/- value for the Z coordinate error.

Therefore, the test block 1 is mounted on the jig 2 of the abutment machining apparatus, and the test three-dimensional (three-dimensional) test is performed on the abutment machining apparatus in accordance with the shape of the error measurement three- When the test 3 is performed on the basis of the value of the three dimensional data TD, the third measuring surface 310 and the second measuring surface 320, The three-axis measuring surface 330 is machined.

For example, as shown in Fig. 3, the shape of the error measuring three-dimensional object 300 is formed as a cube, and the three-dimensional test data TD input to the abutment processing device is divided into error- The test piece 3 is processed on the surface of the error measuring three-dimensional object 300 based on the three-dimensional test data TD, The surface of the error measuring three-dimensional object 300 is not cut or processed at all in a state where the zero point setting of the byte 3 is accurately performed.

On the other hand, in a state in which there is an error in the zero-set position of the byte 3, the surface of the error measuring three-dimensional body 300 is partially cut as shown in Fig.

A first axis measuring surface 310 formed symmetrically with respect to both sides of the error measuring three-dimensional body 300 is formed as an error in positioning the bite 3 relative to the jig 2 when the first axis measuring surface 310 is cut, And the position of the X-axis corresponding to the first axis measuring surface 310 can be corrected.

That is, the direction in which the byte is moved in the + or - direction on the X axis is set in the direction of the first axis measurement surface 310 of the first axis measurement surface 310 formed on both surfaces of the error measurement rigid body 300 , The cut depth of the cut first axis measuring surface 310 is measured and the dimension to be corrected for the position of the cutting tool 3 is measured.

The second axis measuring surface 320 and the third axis measuring surface 330 of the error measuring rigid body 300 are also subjected to cutting of the second axis measuring surface 320 and the third axis measuring surface 330 The error value with respect to the position of the Y-axis and the Z-axis of the cutting tool 3, that is, the correction value to be subjected to the position correction, can be measured using the direction and the depth of cut.

Therefore, after the test block 1 is mounted on the jig 2 of the abutment machining apparatus, the user can confirm the cut state of the error measuring three-dimensional body 300 by only one test working, And it is possible to easily reset the zero point of the byte 3 with accuracy.

The first axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 of the error measuring rigid body 300 are provided with a reference line 340 for confirming the cutting direction by the bite, May be further included.

The reference line 340 may be formed by inserting the test block 1 into the abutment machining apparatus 300 in a state in which the first axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 are symmetrically formed on both sides, And the reference line 340 is used as a reference in confirming the depth of the cut surface of the measuring surfaces on both sides after the test processing. The structure of the reference line 340 is such that the error measuring three- And may have a reference line 340.

6, the shape of the error measuring three-dimensional body 300 formed on the support column 100 is formed as a rectangular bar and the shape of the error measuring three-dimensional body 300 formed on the columnar support 100 is referred to as a first The axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 are formed so as to protrude from the support pedestal 100 so that the edge of the support pedestal 100 is aligned with the reference line (340).

7, the spacing space 350 may be formed such that the first axis measuring surface 310, the second axis measuring surface 320, and the third axis measuring surface 330 are divided into several planes, respectively, The reference line 340 can be formed at the corner of the spacing space. By forming the spacing space 350, the area to be processed by the bite 3 can be minimized and the bite can be prevented from being worn, You can extend it further.

An inner portion 360 may be formed on each of the first axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 as shown in FIG. 8, 310 may provide a reference line 340 to the second axis measuring surface 320 and the third axis measuring surface 330 while the reference line 340 is set to both sides of the inner portion 360.

Therefore, it is possible to confirm the cut direction of the measurement surface by measuring the distance between the first axis measurement surface 310, the second axis measurement surface 320, and the third axis measurement surface 330 from the reference line 340 Of course, it is possible to correct the zero point error of the bite 3 by measuring the cut length.

The method for measuring the cutting direction and the depth of cut of the measurement surface using the reference line 340 may be a method for measuring the cutting direction and the cutting depth using the shape of the test three-dimensional data TD input to the abutment processing apparatus, The reference line 340 can be machined on the error measuring cubic body 300 of the completed test block 1. [

In other words, in utilizing the three-dimensional test data TD for testing based on the shape of the error measuring three-dimensional object 300, instead of forming the reference line 340 in advance in the test block 1 itself, The reference line 340 is processed by the bite 3 when the test block 1 is processed through the test process by including the data for machining the reference line 340 in the three-dimensional stereoscopic data TD, The zero point error of the byte can be confirmed using the reference line 340.

9, the shapes of the first axis measuring surface 310, the second axis measuring surface 320, and the third axis measuring surface 330 of the error measuring solid body 300 are simply referred to as " And the corresponding test three-dimensional solid data TD has the same area corresponding to the first axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 So that a cutting process is performed so that the first axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330 are inserted into the machining plane F When the surface of the error measuring three-dimensional object 300 is processed by the byte 3, the reference line 340 is cut on the surface of the error measuring three-dimensional object 300 by the intruding data A, Processed.

Therefore, by measuring the direction of the cut measurement surface using the reference line 340 machined on the surface of the error measuring stub 300 after the test processing, the measured values of the X, Y and Z coordinate errors of the bite can be changed to + or - And the depth of the cut is numerically expressed, so that it is possible to measure the positional value of the byte with respect to the jig, that is, the zero point error of the byte.

Meanwhile, the error measuring unit 300 is preferably made of a metal material as described above, and the printing layer 400 may be further provided on the surface thereof.

The print layer 400 can be printed or painted using the pigment on the surface of the error measuring three-dimensional object 300, or can be formed by applying a surface to cover a specific color with a release material.

Therefore, when the first axis measuring surface 310, the second axis measuring surface 320, and the third axis measuring surface 330 of the error measuring three-dimensional object 300 are cut by the cutting tool 3 of the abutment processing apparatus The printed layer 400 is peeled off so that the user can easily confirm the direction in which the cut is made.

A display scale (not shown) is displayed on the first axis measuring surface 310, the second axis measuring surface 320, and the third axis measuring surface 330 formed on the error measuring unit 300, The cut depth of the test block 1, which is the result of the test machining without measuring the cut depths of the axis measuring surface 310, the second axis measuring surface 320 and the third axis measuring surface 330, The user can easily confirm with the naked eye.

At this time, the display scale may display a scale on the surface of the error measuring stereoscopic body 300, or may be provided with a display scale on the surface of the error stereoscopic body 300 by a negative or positive angle.
