Description

Healing abutment

The present invention relates to a healing abutment, and more particularly, to a healing abutment capable of providing various information as a single marker.

In the case of a missing tooth, a bridge was used in which a denture was inserted or a surrounding portion of a tooth was used as a column and a missing portion was covered with a metal or the like. However, such a procedure has several problems, such as a denture or a bridged artificial tooth having a weak chewing force and adversely affecting surrounding teeth. As a result, the dental implant treatment was introduced as a result of advanced dental treatment. Such an implant procedure forms an artificial tooth root on the alveolar bone and combines the artificial tooth, which is a final prosthesis made like a real tooth, using the tooth to obtain the effect that the patient uses the actual tooth.

In the implanting process, an implantation groove is formed by using a tool such as a drill to insert a fixture into an alveolar bone missing teeth, and tapping is performed as a selection operation for firmly implanting a fixture in the implantation groove. Thereafter, the fixture is inserted into the grooved groove, and a cover screw is tightened to prevent foreign matter from penetrating the fixture, and the first operation is completed by covering and sealing the gums. Then, as a secondary operation, about 3 to 6 months have elapsed, the sutured gum is cut again, and the cover screw is removed from the fixture. After considering the type of abutment to be fastened, the healing abutment is selected Conclude. The healing abutment is such that the gums are cleanly formed on the fixture before the abutment is fastened to the fixture. After the gums suitable for the abutment are formed about two to three weeks after the fastening, After the abutment is removed again, the abutment is joined, and the implanted prosthesis is completed by engaging an artificial tooth prosthesis having the shape of a natural tooth on the upper side of the artificial tooth.

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 order to solve such a conventional problem, a healing abutment 10 as shown in Fig. 1 is known. The healing abutment includes a gum creation part 11 and an insertion part (not shown) provided under the gum creation part and inserted into the implant. A screw member 20 is inserted into the healing abutment 10 so that the healing abutment can be fixed to the implant.

A marker 12 for defining the arrangement and shape between the abutment and the implant is formed on the outer surface of the upper part of the abutment. The marker 12 can be visually recognized by a practitioner so that information on the arrangement and shape of a report can be obtained only by the marker 12, and a scanning device is not required. In addition, the error that may occur during the scanning process can be minimized, and the treatment time can be shortened because there is no process of fastening / separating separate parts.

Specifically, the markers 12 are variously provided as shown in FIG. (3 mm, 4 mm, 6 mm, 8 mm) and the size of the connector (3.4 mm), for example, through various combinations shown in FIGS. 2A to 2 mm, 4.1 mm, 5.0 mm, and 6.0 mm) can be recognized by forming two or more circular grooves having various sizes in various combinations.

The prior art healing abutments having such markers have the following problems.

First, there is a possibility of inputting erroneous information because the combination of markers is very diverse and difficult to interpret.

In order to check the height of the abutment, the size of the connector, etc., at least two or more markers are formed at the uppermost part because the markers used for the markers contain only one information, so that information confirmation is not intuitive .

In addition, the operator analyzes the code with the naked eye and inputs the scanned information to the PC. In this process, there is a disadvantage that the information input error is likely to occur when the information is misinterpreted.

SUMMARY OF THE INVENTION It is a general object of the present invention to provide a healing abutment capable of giving various kinds of scan information using a single marker.

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

The healing abutment 100 according to the present invention is for forming a shape that is inserted into an implant and cleans the gums before covering an artificial dental prosthesis, and includes an abutment body and a marker.

The insertion portion 111 is a portion inserted into the implant 200. Specifically, the insertion portion 111 is inserted into the implant 200 to allow the abutment body 110 to be held in the implant 200. The insertion portion 111 includes a lower portion 1111 of a polygonal shape for preventing relative rotation when the implant 200 is engaged with the upper portion 1111 extending upward from the lower portion 1111, 1112).

The lower portion 1111 of the implant 200 is provided with a rotation preventing surface and the rotation preventing surface is coupled to the inner surface of the rotation preventing portion provided in the implant 200 to prevent the body from rotating relative to each other .

The gum creation part 112 is disposed on the upper side of the insertion part 111 and guides the gum to be generated. The gum formation part 112 is disposed on the upper side of the insertion part 111 and is capable of generating the shape of the gum on the cervical part of the subject. The gum creation part 112 includes an inclined part 1121 whose diameter (or cross sectional area) increases from the insertion part 111 toward the upper side and a through hole 113 whose diameter is kept constant. At this time, the slope portion 1121 may have the shape of an inverted truncated cone.

The through hole 113 is chamfered in a round shape at an upper edge portion and an upper edge portion with a predetermined outer diameter from the upper end of the inclined portion 1121.

The through hole 113 penetrates through the screw member 130 coupling the healing abutment and the implant 200. The through hole 113 is configured to penetrate the lower surface of the insertion portion 111 and the upper surface of the gum forming portion 112. The diameter of the through hole 113 is reduced by the first step 1131 and is extended to the lower surface of the insertion portion 111 while the diameter of the through hole 113 is reduced downward from the upper surface of the gum forming portion 112. A predetermined thread is formed on the inner circumferential surface of the through hole 113 on the lower side of the insertion portion 111 and the screw member 130 inserted through the through hole 113 is inserted .

The head 131 of the screw member 130 is caught and fixed to the abutment body 110 by the first step 1131. The position of the first step 1131 corresponds to the length of the head part 131 of the screw member 130. That is, the distance from the upper surface of the gum creation part 112 to the first step 1131 is substantially equal to the length of the head part 131 of the screw member 130. Since the first step 1131 is positioned as described above, when the head part 131 of the screw member 130 is inserted into the abutment body 110, the head part 131 of the screw member 130 131 can be positioned at the same position as the uppermost end of the gum forming portion 112.

When the uppermost end of the head part 131 is located at the same position as the uppermost end of the gum forming part 112, foreign matter such as food waste is not left in the healing abutment after the healing abutment is inserted into the oral cavity, Lt; / RTI >

The marker 120 is formed on the outer surface of the gum formation part 112 and represents at least two pieces of information for arrangement and shape recognition of the implant 200 and the healing abutment. Such a marker 120 may be provided as a single unit and a single marker 120 may represent at least two or more pieces of information using a size change and a shape change. In addition, only a single marker 120 is formed on the outer surface of the gum creation part 112.

The single marker 120 may be recessed from the upper outer surface of the gum forming part 112. But it is not limited thereto and may be a protruding shape protruding from the outer surface of the gum formation part 112 and may have a shape of polygonal, circular, letter or numeral.

The single marker 120 may also be used to display information for placement and shape recognition of the implant 200 and the healing abutment using either color or barcode.

The information for the placement and shape recognition of the implant 200 and the healing abutment may be any one of the height of the healing abutment, the diameter of the healing abutment, the position of the rotation preventing surface, and the size of the implant 200 , And the single marker 120 may visually represent at least two, preferably three, of these various pieces of information.

On the other hand, in FIG. 6, a single marker 120 is depressed and has a polygonal shape. At this time, one of the markers 120 can be placed in parallel with the anti-rotation surface. That is, a side line _(A l) passing through the polygon is able to be placed parallel to the status and the line (l _B) through the non-rotating surface. In this way, since the single marker 120 is placed in parallel with the rotation-preventing surface, it is possible to confirm at least the direction in which the rotation-preventing surface lies in view of the single marker 120. [

When the single markers 120 are depressed, the widths of the outer side surface and the inner side surface are made different from each other or equal to each other, so that information for placement and shape recognition of the implant 200 and the healing abutment can be identified . For example, FIG. 7 exemplifies markers 120 of various shapes. When the markers 120 are in a rectangular shape as shown in FIG. 7 (a), the height of the healing abutment may be 3.0 mm , The height of the healing abutment is 5.0 mm when the marker 120 is trapezoidal as shown in Fig. 7 (b), and the trapezoidal shape of the marker 120 is inverted as shown in Fig. 7 (c) , The height of the healing abutment is 5.0 mm, respectively. However, the shape and the height of the abutment are not limited to these examples, and various modifications are possible according to convenience.

In addition, when the single marker 120 is depressed, information for placement and shape recognition of the implant 200 and the healing abutment can be identified by changing the length of the depression.

For example, FIG. 8 (a) shows a quadrangular groove with only about half of the hole. In this case, since the diameter of the abutment is mini and the cross-sectional shape is square, the height of the abutment is 3.0 mm Can be displayed at the same time.

8 (b) shows a quadrangular groove depressed to extend to the through hole 113. In this case, since the abutment diameter is regular and the sectional shape is rectangular, the height of the abutment is 3.0 mm.

In FIG. 8C, the marker 120 has a trapezoidal shape and only a half of the groove. In this case, since the diameter of the abutment is mini and the sectional shape is a trapezoidal shape, And the height of the electrode is 5.0 mm.

In FIG. 8D, the marker 120 has a trapezoidal shape and a groove with only about half of the groove. In this case, since the cross-sectional shape is a trapezoid, indicating that the diameter of the abutment is regular, And the height of the electrode is 5.0 mm.

As described above, various information can be simultaneously expressed by varying the groove depth, groove shape, and the like as one marker.

The screw member is inserted into the through hole of the abutment body, and the lower end of the screw member is screwed to the implant. The abutment body is inserted into the implant so that the abutment body is fixed to the implant.

The screw member 30 includes a head portion inserted into the through hole of the abutment body portion, and a bag portion extending from the head portion and screwed to the implant. The head portion is caught by the first step in the through-hole.

In the drawings, the implant is referred to as a generally cylindrical shape, and a thread is formed on an outer circumferential surface thereof. The implant is provided with a receiving hole into which a healing abutment can be inserted. The receiving hole includes an upper portion having a circular cross section, a rotation preventing portion provided at a lower portion of the upper portion and having a polygonal shape, And a threaded portion formed on the inner surface and screwed into the thread of the screw member.

The healing abutment according to the present invention has the following advantages.

In conventional healing abutments, since each marker contains only a single piece of information, a plurality of markers have to be combined in various forms in order to express a plurality of pieces of information. However, in the case of using such various markers, there is a disadvantage that information confirmation is not intuitive and highly likely to recognize false information.

Especially, the operator analyzes the marker with the naked eye and inputs it into the computer. In this case, if the user inputs the information in error, it causes a considerable problem.

On the other hand, the present invention has an advantage that information confirmation is intuitive and the possibility of obtaining erroneous information is very small because it is implemented to represent various information through a single marker.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art. There will be. Accordingly, the true scope of protection of the present invention should be determined by the appended claims.
