Description

Healing abutment set < RTI ID = 0.0 >

The present invention relates to a healing abutment set capable of being scanned, and more particularly, it relates to a set of a healing abutment capable of scanning, and more particularly, The present invention relates to a scanable healing abutment set which can guide a user to perform matching on a CAD program after a scan even if the user does not use the scan.

Implant refers to a replacement that restores the original tissue when it is lost, but refers to a series of procedures that implanted an artificial tooth in a dentist.

In other words, the implant implants a root fixture made of titanium or the like, which does not have a rejection reaction to the body, so as to replace the lost root (roots), the teeth are inserted into the alveolar bone, It is a series of dental procedures that restore tooth function.

In general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants do not injure the surrounding dental tissue, and they have the same function and shape as the natural teeth, but do not have cavities. Therefore, they can be used semi-permanently.

Implants improve the function of dentures in single and double edentulous and fully edentulous patients, as well as single-tooth restorations, improve the aesthetic aspects of dental prosthesis restoration, and further disperse the excessive stress applied to the surrounding supporting bone tissue, Which helps to stabilize.

We will briefly review the process of implanting these implants.

First, the placement position of the fixture is drilled using a drill. Thereafter, the fixture is placed in an alveolar bone at the perforated portion to perform artificial fusion so as to become an artificial root.

After a certain period of time, when the fusion of the fixture is completed, insert an abutment into the fixture and fix it with an abutment screw so that the fixture and abutment become one body.

Then, as a final prosthesis, a crown of the same shape as a natural tooth, that is, an artificial dental prosthesis is covered with an abutment, thereby completing the implant procedure.

If you need to shape your gums well before implanting an artificial dental prosthesis, you can prefix the fixture with a healing abutment. The healing abutment at this time can be used temporarily until the artificial tooth is put on.

On the other hand, in order to connect an artificial tooth prosthesis to an abutment, it is necessary to fabricate an artificial tooth prosthesis in a form suitable for the oral structure of the patient.

These artificial dental prostheses raise the impression of the patient's teeth, create a model in the dental laboratory based on the impression, and attach the implant scan abutment (abutment model) to the model. After the scan, the CAD data of the implant scan abutment is matched to the scan data on the CAD program, and the prosthesis model suitable for the patient's tooth shape is created.

However, this method has a problem that the process is somewhat complicated, for example, the impression is made and the model is made based on the impression.

Recently, implant scan abutment combined with fixture has been considered as a scan method, but this also inconveniences and inconvenience to further combine implant scan abutment.

In fact, given the fact that many patients have considerable resistance to dental treatment, there may be a considerable burden to proceed with the scan after further consolidation of the separate implant scan abutment.

Therefore, it is expected that if the healing abutment can include the scan function, it will be possible to improve the convenience of the implant treatment by avoiding the burden of using the implant scan abutment separately.

In order to fully understand the advantages of the present invention, its operational advantages, and the objects attained by the practice of the present invention, reference should be made to the accompanying drawings, which illustrate preferred embodiments of the present invention, and to the description in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

FIG. 1 is a view illustrating a state in which a scan is performed through a healing abutment of a scanable healing abutment set according to an embodiment of the present invention, FIG. 2 is a view showing the fixture shown in FIG. 1 and the healing abutment Fig. 3 is a perspective view of the healing abutment, Fig. 4 is a rear perspective view of Fig. 3, and Fig. 5 is a side view of Fig.

Referring to these drawings, the scanable healing abutment set according to the present embodiment can form a shape for the gums to be well treated during the implant treatment, and can also be used for removing the healing abutment The healing abutment 130 can be scanned and matched on the CAD program without removing the healing abutment 130 even if the posterior implant scan abutment is not tightened. Thereby improving convenience.

Such a healing abutment 130 may be used in combination with a fixture 110, as shown in FIGS.

Prior to the description of the healing abutment 130, the fixture 110 will be briefly described. The fixture 110 is a kind of screw that is placed on the alveolar bone. When the fixture 110 is placed in the alveolar bone, The root is formed.

The fixture 110 may include a body portion 111 and a head portion 112 constituting an upper region of the body portion 111. [ In the present embodiment, the body portion 111 and the head portion 112 are separately described for convenience, but they are integrally threaded structures made of a titanium material.

On the outer surface of the main body 111 and the head 112, a thread 113 is formed as a means for screwing the alveolar bone into the alveolar bone.

In the drawings, pitch intervals of the threaded portions 113 formed on the outer surfaces of the main body 111 and the head 112 are substantially equal to the height of the mountain.

However, since the scope of the present invention can not be limited to the shape of the drawing, the pitch interval of the screw portion 113 formed on the outer surface of the body portion 111 and the head portion 112 may be different from the pitch of the mountain. For example, the pitch interval of the screw portions formed in the main body portion 111 may be formed to be larger than the pitch interval of the screw portions formed in the head portion 112. In this case, a strong binding force can be provided at the time of initial mounting.

The body portion 111 and the head portion 112 may be of a cylindrical type having the same cross sectional area along the direction in which the fixture 110 is placed differently from the illustrated shape, It may be a tapered type.

For reference, a lower end portion of the main body 111 or an outer wall thereof may be provided with a positioning position guide portion (not shown) and a cutting edge portion (not shown) for guiding the positioning position, The positioning position guide unit (not shown) and the cutting edge unit (not shown) may be means for allowing the fixture 110 to be placed at a predetermined position.

A screw fastening female threaded portion 111a for fastening the abutment screw 120 is formed in the body portion 111. [

Next, as described above, the healing abutment 130 serves to shape the gum so that the gum can be well treated during the implant treatment.

In other words, the healing abutment 130 is shaped to allow the gum to be easily removed by being fixed to the fixture 110, as shown in FIGS. 1 and 2, after the fixture 110 is placed in the alveolar bone. Of course, the healing abutment 130 may only be used temporarily until a crown, i.e., an artificial dental prosthesis, is applied.

In addition, the healing abutment 130 applied in the present embodiment plays a role of making it possible to match on the CAD program after the scan in manufacturing the artificial dental prosthesis in addition to the basic role of making the shape so that the gums can be well treated .

3 to 5, the healing abutment 130 according to the present embodiment includes an abutment body 131 and one side of the abutment body 131, And main and reference portions 141 and 142 for placement and shape recognition that form a reference for placement and shape recognition at the time of scanning for production of the image.

The abutment body 131 is a portion forming the lower end outer appearance of the healing abutment 130 according to the present embodiment.

The abutment body 131 has a structure in which the width is gradually widened toward the upper end portion. The boundary edges with the scan healing head 132 forming the upper end of the abutment body 131 have corner portions where two vertical and horizontal lines connecting round or oblique lines meet. This allows the gums to be well cared for and to create artificial teeth that are similar in shape to previous natural teeth.

Of course, since the scope of the present invention is not limited to the shape of the drawings, the healing abutment 130 according to the present embodiment is not limited to the shape provided in the present embodiment, It may be applied to various shapes in which the body 131 is slightly deformed.

A screw hole 131a is formed in the abutment body 131 to pass through the abutment screw 120 used when the healing abutment 130 is fastened to the fixture 110.

The wall surface of the screw hole 131a has a stepped structure in a predetermined section as shown in a cross section in FIG. 2, so that the abutment screw 120 can receive the force without missing.

As an important condition of the healing abutment 130 for providing the role of allowing the healing abutment 130 according to the present embodiment to match on the CAD program after the scan in manufacturing the artificial dental prosthesis, In order to match the scan data of the butt 130 with the CAD data, the data necessary for matching and matching data of mutually corresponding portions should be provided.

3D modeling of the healing abutment 130 may be selected as the CAD data. The 3D modeling of the healing abutment 130 may be selected as the CAD data from the collected library that collects various things having different shapes of the healing abutment 130, Can be selected. More precisely, the points of the polygon forming the scan data are called polygons, and similar data of the polygon having a certain pattern can be found so that the scan data and the CAD data of the healing abutment 130 coincide with each other .

In this case, since the CAD data has a predetermined pattern, it is possible to obtain a similar structure of the implant scan abutment when the scan data is obtained by obtaining the scan data. If not, three points or one The abutment body 131 of the healing abutment 130 according to the present embodiment may be provided with the arrangement and shape recognition Main reference portions 141 and 142 are provided.

The placement and shape recognition main reference portions 141 and 142 form a reference for placement and shape recognition at the time of scanning for manufacturing an artificial dental prosthesis.

The main reference portions 141 and 142 for the placement and shape recognition are connected to the fixture 101 immersed in the patient's gums to scan the healing abutment 130 in order to obtain data on the configuration and shape of the fixture. The data of the CAD model of the healing abutment 130 can be aligned on the basis of the scan reference data of the shape generated by the scan and the main reference portions 141 and 142 for shape recognition. That is, when the scan by the scanner 180 is completed as shown in FIG. 1, the healing abutment 130 can obtain data on the position of the patient in the teeth.

Since the structure of each tooth is slightly different for each patient, the healing abutment 130 collects the position of the tooth placed on the teeth through the scan, thereby making it possible to accurately make a crown, that is, an artificial dental prosthesis, have.

That is, if the dentist sends the scan modeling data of the healing abutment 130 coupled to the fixture 110 and the teeth generated by the scan to the laboratory, An artificial tooth prosthesis suitable for the structure can be manufactured.

Since the tooth structures of the patients are different from each other, when the healing abutment 130 is engaged with the fixture 110, the placement of the healing abutment 130 and the teeth, It is possible to design the shape of the artificial tooth prosthesis to be matched to each tooth from the scan modeling of the arrangement pattern set in accordance with the healing abutment 130, even if the relationship and the shape of the teeth are not consistent.

In this manner, the main reference portions 141 and 142 for placement and shape recognition formed on the scan-healing head 132 can obtain accurate modeling of the arranged aspects in a state where the healing abutment 130 is disposed on the teeth The data of the healing abutment 130 collected through the scan is processed by an algorithm to follow or match the data of the CAD model of the healing abutment 130 so as to generate accurate modeling .

In this embodiment, the arrangement and shape recognition main reference portions 141 and 142 for providing such a role are first and second arrangements arranged in pairs on both sides with respect to the center axis of the abutment body 131, The main reference portions 141 and 142 are used. The main reference portions 141 and 142 for placement and shape recognition may be disposed in the scan healing head 132. [

At this time, the shapes of the first and second arrangement and shape recognition main reference portions 141 and 142 are different from each other. Of course, unlike the drawings, the main reference portions 141 and 142 for placement and shape recognition may be formed only on one side of the abutment body 131, or may be formed on both sides thereof.

The first and second arrangement and shape recognition main reference portions 141 and 142 are means for clearly recognizing the contrasts due to the scan light and clearly recognizing the main edges 143a and 143b, And a second edge distinguishing main edge 144a.

For the formation of the first and second shade discriminating main edges 143a and 143b and the second shade discriminating main edge 144a, the first arrangement and shape recognition main reference portion 141 and the second arrangement and shape recognition main The reference portion 142 may be provided with main edge dividing walls 145a and 145b for forming first edges and main edge dividing walls 146a for forming a second edge, respectively.

The first edge forming main exit walls 145a and 145b and the second edge forming main exit wall 146a are provided with the first and second light discriminating main edges 143a and 143b and the second and third light discriminating main edges 144a The outer surface of the abutment body 131 may be formed as a flat surface in order to provide an angle to the outer surface of the abutment body 131, that is, in the present embodiment.

In other words, in the state that the outer wall of the abutment body 131 is rounded, the rounded surface of the abutment body 131 is cut to form the first edge forming main cleavage walls 145a, 145b and the second edge forming main By forming the cleavage wall 146a, the first and second main discriminating main edges 143a and 143b and the second main discriminating main edge 144a can be naturally formed to achieve the standard of the scan data.

As described above, in the present embodiment, the first and second edge distinguishing main edges 143a and 143b and the second and third discriminating main edges 143a and 143b are separated by the first edge forming main cutting walls 145a and 145b and the second edge forming main cutting wall 146a, A main edge 144a may be formed. In other words, the first and second edge distinguishing main edges 143a and 143b and the second and third edge distinguishing main edges 143a and 143b are separated by the boundary line between the first edge forming main cutting walls 145a and 145b and the second edge forming main cutting wall 146a A main edge 144a may be formed.

At this time, a plurality of first edge-forming main separation walls 145a and 145b formed in the first arrangement and shape recognition main reference portion 141 are connected to each other at different angles. Accordingly, the first and second discriminating main edges 143a and 143b formed by the boundary lines of the first edge forming main separation walls 145a and 145b are also multi-divided.

On the other hand, the second edge forming main separation wall 146a formed in the second arrangement and shape recognition main reference portion 142 forms a single one surface. Therefore, the second and third discriminating main edge 144a formed by the boundary line of the second edge-forming main separating wall 146a becomes the perimeter boundary line itself of the second edge-forming main separating wall 146a.

If the healing abutment 130 as described above is applied, even if the implant scan abutment is not used as before, the healing abutment 130 itself is scanned with the scanner 180 as shown in FIG. 1 , It is convenient from the viewpoint of the practitioner since the scan data can be sent to the dental laboratories and the artificial tooth prosthesis can be produced directly based on the data. It is also good because you do not have to visit the dentist many times in the patient's particle.

According to the present embodiment having the structure and function as described above, it is possible to make the shape of the gum so that the gum can be well treated during the operation of the implant, and even if the implant scan abutment is not used, It is possible to guide the implantation on the post-CAD program so that the convenience of the implant procedure can be improved.

FIG. 6 is a view illustrating a state in which scanning is performed through a scanable healing abutment set according to another embodiment of the present invention, and FIG. 7 is a view showing a combination of the fixture, the healing abutment and the scan post shown in FIG. 8 is a perspective view of a scan post, FIG. 9 is a cross-sectional view of FIG. 8, and FIGS. 10 and 11 are views showing a scan post from a different angle as a modification of the scan post, respectively.

Meanwhile, although the scan operation can be performed with only the above-described healing abutment 130, scanning may be difficult with only the healing abutment 130 according to the oral structure of the patient. For example, it may be difficult to scan through the scan healing abutment 130 because the height of the scan healing abutment 130 is too low to be covered by surrounding teeth.

If the healing abutment 130 alone can not be scanned, a scan post 150 may be further coupled to the healing abutment 130 as in the present embodiment.

6 through 9, the scanable healing abutment set according to the present embodiment may include a healing abutment 130 coupled to the fixture 110 and a scan post 150 .

At this time, when the scan through the healing abutment 130 is not possible, the used scan post 150 is coupled to the healing abutment 130 as shown in FIGS. 6 and 7 to assist the scan to proceed .

At this time, since it is difficult to rotate the scan post 150 arbitrarily while being coupled to the healing abutment 130, in this embodiment, the scan post 150 does not rotate relative to the healing abutment 130 And is then coupled to the healing abutment 130.

The scan post 150 includes a post body 151, a sub reference unit 160 for arranging and recognizing a shape, which is provided at one side of the post body 151 and forms a reference for placement and shape recognition at the time of scanning, And a head coupling portion 156 provided on the other side of the post body 151 and coupled to the scan healing head 132 of the healing abutment 130. [

First, the post body 151 is a part forming the appearance of the scan post 150 according to the present embodiment. The post body 151 is applied as a cylindrical type except for the sub reference portion 160 for placement and shape recognition.

Next, the sub-reference portion 160 for placement and shape recognition forms a reference for placement and shape recognition at the time of scanning. The sub-reference portion 160 includes a first and a second arrangement of the above-described healing abutment 130, The main reference portions 141 and 142 have the same structure and shape but the same roles.

That is, in this embodiment, the placement and shape recognition sub-reference unit 160 includes a plurality of sub-edges 161a to 161h for distinguishing between light and dark formed on the post body 151 for distinguishing between dark and light due to light during scanning A plurality of edge sub-dividing walls 163a to 163d are formed in the post body 151 to form the sub-edges 161a to 161h. In other words, the sub-edges 161a to 161h for distinguishing the light and dark can be formed by the boundary lines of the plurality of sub-dividing walls for sub-dividing 163a to 163d.

The plurality of edge forming sub-dividing walls 163a to 163d have a first edge forming sub-dividing wall portion 163a for forming the widest surface and a second dividing sub-dividing wall portion 163a for forming the first edge forming sub- A second edge forming sub-dividing wall portion 163b which is arranged so as to intersect the first edge forming sub-dividing wall portion 163a and a second edge forming sub- A sub-dividing wall 163c for forming a third edge which is arranged so as to intersect the sub-dividing wall 163b and a sub-dividing wall 163b for forming a first edge at the lower end of the first dividing sub- And a fourth edge formation sub-folding wall portion 163d disposed so as to intersect with the first edge portion 163a.

As described above, the sub-dividing walls 163a to 163d for forming edges are formed in the post body 151 and the sub-edges 161a to 161h for distinguishing the light and dark are formed by the boundary lines of the sub-dividing walls 163a to 163d. As a result, the discrimination of light and shade due to the scan light can be made clear, and the efficiency of the scan can be enhanced.

Finally, the head engaging portion 156 is a portion that is coupled to the scan healing head 132 of the healing abutment 130.

9, a head receiving groove 157 is formed in which the scan healing head 132 of the healing abutment 130 is partially received. The head receiving groove 157 is formed in the head receiving groove 157, And the outer wall of the scan healing head 132 of the healing abutment 130 have the same curvature. Thus, the healing abutment 130 and the scan post 150 can be combined well.

Further, the inner wall of the head receiving groove 157 is engaged with the first and second arrangement and shape recognition main reference portions 141 and 142 of the healing abutment 130 so as to be rotated relative to the healing abutment 130 An anti-rotation portion 158 is formed so as to be blocked. When the scan posts 150 are coupled to the healing abutment 130 as shown in FIG. 7, their relative rotation can be prevented.

The antirotating part 158 may also be provided in a plurality of opposing main reference parts 141 and 142 for the first and second arrangement and shape recognition of the healing abutment 130. The antirotating part 158 may include a plurality of antirotating parts 158, Are all the same.

Although the shapes of the first and second arrangement and shape recognition main reference portions 141 and 142 are different, even if the shapes of the anti-rotation portions 158 are processed to the same, There is no problem in joining the scan post 150 to the healing abutment 130 as shown in FIG. Particularly, when the antirotating portions 158 are formed in the same shape as in the present embodiment, the scan post 150 can be coupled regardless of the direction, thereby greatly improving convenience in use.

However, it is contemplated that many anti-rotatable portions 258a, 258b, such as the scan posts 250 of FIGS. 10 and 11, illustrate variations of the first and second arrangements of the healing abutment 130, Shaped portions 141 and 142, respectively.

Even if the structure of this embodiment is applied, it is possible to make a shape so that the gums can be well treated during the implant treatment, and also, even if the implant scan abutment is not used as in the past when manufacturing the artificial tooth prosthesis, So that the convenience of the implant treatment can be improved.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims.
