Description

An abutment for healing

The present invention relates to a healing abutment used in the treatment of a dental prosthesis, and more particularly, to a healing abutment which can simplify a scanning process or an impression preparing process in an implant treatment.

Generally, an implant implies a replacement that restores when the original tissue has been lost, but implants an artificial tooth in a dentist. Implant is a procedure in which a root formed of a metal material that does not have a rejection reaction to the human body is replaced in the alveolar bone that the tooth has escaped to replace the lost root, and then the tooth is restored by fixing the artificial tooth.

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 also improve the function of dentures in patients with single missing teeth restoration, as well as partial and total toothless teeth, and improve the aesthetic aspects of dental prosthesis restoration. Furthermore, it helps to stabilize the dentition as well as to disperse the excessive stress applied to the surrounding supporting bone tissue.

The dental implant procedure is divided into a surgical procedure for implanting a fixture into the alveolar bone and a prosthetic procedure for attaching an artificial tooth by connecting the abutment to the implanted fixture.

The procedure of these implants can be varied. The implant procedure described below is a fixture level impression method for completing a model in the oral cavity by connecting an impression coping in the oral cavity when the impression is made during the prosthesis process.

First, drilling and tapping are performed on the alveolar bone to form a groove conforming to the fixture dimension, and a mount is fastened to the upper part of the fixture. Thereafter, the fixture and the mount are inserted into the alveolar bone using the surgical handpiece, and then the mount is removed from the fixture, so that the fixture is inserted into the alveolar bone.

The first operation is completed by fastening the cover screw to the top of the fixture and sealing the fixture.

The cover screw prevents bacteria and foreign substances present in the mouth from intruding into the fixture while waiting for the fixture's osseointegration. The duration of ossification is somewhat different depending on the patient's bone quality and implantation position, but usually takes 3 to 6 months.

Next, the gums are opened through the second operation to expose the cover screws, check the degree of fusion of the fixtures, and remove the cover screws. And a healing abutment is fastened to the top of the fixture for aesthetic gingival formation and waited for two to three weeks. In order to improve the complexity of such a secondary operation, a first-aid procedure for fastening the healing abutment is often used, omitting the process of fastening and removing the cover screw.

Next, after confirming the esthetic gingival formation, the healing abutment is removed, and the impression coping is fastened to the upper part of the fixture to make the prosthesis. The impression material is then used to create a preliminary impression in the mouth and remove impression copings.

Thereafter, a tooth model is prepared, an artificial tooth, that is, an artificial crown is pierced, an abutment is fastened to the upper part of the fixture, and an artificial tooth is completed by fixing a prosthesis or artificial crown on the abutment.

However, in recent years, a CAD cam system has been used to manage all processes from design to manufacture by computer. This can be done very precisely because it is so close to perfection.

After the first operation, the healing abutment is fastened to the top of the fixture even after the first operation, and after 2 to 3 weeks, the healing abutment is removed after the aesthetic gum formation is confirmed.

Then, the scan abutment is fixed in the oral cavity, and then the three-dimensional scanner is scanned to secure the three-dimensional scan data. The shape of the scan structure in the thus obtained three-dimensional scan data is compared with the shape file of the abutment inputted in advance, and the position of the fixture position of the tooth to be implanted, the exact depth and direction, and the position of the center coordinate Extraction is performed by reverse engineering, and the prosthesis is manufactured accordingly.

Healing abutments are generally used for aesthetic gum formation during implant procedures such as impression taking and CAD cam systems.

However, even if any method for manufacturing the prosthesis is used in the implant surgery, the conventional healing abutment is separated from the fixture, and thereafter, the impression coping or the scan abutment is additionally fastened to the fixture. As a result, a complicated procedure is required inside the narrow mouth, which is not easy and inconvenient for the patient.

The healing abutment 10 according to the present embodiment is applied when a prosthesis is manufactured using a CAD cam system, and includes a scanning post 200 as a marker for securing three-dimensional scan data.

The healing abutment 10 includes a healing body 100 that can be engaged for a predetermined period of time to form an aesthetic gum on the fixture 20 that is fusion-bonded to the alveolar bone, and a three- And a scanning post 200 detachable on the healing body 100 to calculate a position value.

The fixture 20 includes an insertion groove 22 into which the lower end of the healing abutment 10 can be inserted and a threaded portion 22 which is fastened to the coupling portion 150 of the healing abutment 10 in the lower portion of the insertion groove 22. [ (Not shown), and a screw 24 that is machined on the outer circumferential surface to be placed in the alveolar bone. The insertion groove 22 may be formed in a polygonal shape so as to have a predetermined directional connection with the prosthesis. Although the insertion groove 22 is shown as a regular hexagon in FIG. 1, the insertion groove 22 is not limited to the regular pentagon, Having various shapes of polygons.

The healing body 100 may be integrally formed of a metal such as titanium and includes a shape recognition unit 110 having a first polygonal shape for recognizing the shape of the fixture 20, A column portion 130 integrally disposed at a lower portion of the protrusion 120 and a second polygon disposed at a lower portion of the column portion 130 and insertable into the fixture 20, And a fastening hole 160 penetrating from the shape recognition unit 110 to the insertion unit 140 so that the fastening unit 150 coupled to the fixture 20 can pass.

The shape recognizing unit 110 may have a plurality of outer end faces 112 and edges 114 constituting a first polygon for a good bonding strength with the scan post 200. As the outer end faces 112 and the edges 114 of the shape recognition unit 110 are increased, the operator can move the healing body 100 ). ≪ / RTI >

The shape recognition unit 110 may be formed of a first polygon having the same shape as the insertion groove 22 of the fixture 20. When the healing body 100 is coupled to the fixture 20 through the coupling part 150, the coupling shape of the insertion part 140 with respect to the insertion groove 22, ). ≪ / RTI > The shape of the first polygon of the shape recognition unit 110 is formed in the shape of the insertion groove 22 when the shape recognition unit 110 is formed to have the same shape as the insertion groove 22, Lt; / RTI >

2, when the healing body 100 is fastened in a state exposed on the fixture 20 before the prosthesis is manufactured, the shape recognizing unit 110 may be configured to allow the healing body 100 So as to be rounded at least at the edge of the upper surface.

The shape recognizing unit 110 is disposed at the lower side of the outer end faces 112 and the edges 114 and enlarges the fixing unit 240 to the width of the protrusion 120 when the scanning post 200 is engaged with the scanning post 200 And may include a guide portion 116 that is tapered to have a width that widens from top to bottom for guiding. In addition to this, the scan post 200 extends from each of the outer end faces 112 in correspondence with the lower end of the inner end faces 270 of the scan post 200 so that the scan post 200 stably seats in the healing body 100 Cutting surfaces 118 may be provided.

When the fastening part 150 is exposed and coupled to the fixture 20, the inside of the oral cavity is not damaged by the healing body 100 during chewing, and foreign substances such as food or therapeutic medicine do not remain on the fastening hole 160 The shape recognizing unit 110 may be formed to have the same level as the upper surface of the fastening part 150 that is engaged with the fixture 20 on the upper surface around the fastening hole 160.

The protrusion 120 is disposed at a lower portion of the guide portion 116 and protrudes from the shape recognition portion 110 so as to be closely contacted with the fixed portions 240 of the scan post 200 when the protrusion 120 is engaged. The protrusion 120 may be disposed at a portion of 0.5 mm to 1.5 mm from the upper surface of the shape recognition unit 110. If the protrusion 120 is disposed at a portion less than 0.5 mm, the coupling of the scan post 200 is incomplete and it is difficult to accurately acquire the scan data. When the protrusion 120 is positioned at a portion of 1.5 mm or more, the healing body 100 is exposed The gums grow to cover the protrusion 120, so that the coupling of the scan post 200 is impossible.

The column portion 130 integrally connects the protrusion 120 and the insertion portion 140, and can be tapered so as to have a wider width toward the upper portion. If the column portion 130 has a wider width or has the same width at the upper and lower portions as the portion goes downward, the gap between the healing body 100 and the teeth (or gums) becomes excessively narrow, And it is difficult to couple to the fixture 20, and even when scanning, the interval is very narrow and the arrival of the scanning light becomes poor.

The insertion section 140 is formed in a shape of a second polygon which is smaller than the shape recognition section 110 and is the same as the insertion groove 22 and has a plurality of insertion faces 142 and insertion edges 142 144). The insertion portion 140 moves to the inside of the insertion groove 22 by fastening the fastening portion 150 so that the insertion depth of the healing body 100 The joining direction can be grasped accurately. Since the insertion portion 140 is formed in the shape of the second polygon so that the direction of the scan assert butt 10 with respect to the fixture 20 is specified, It is possible to use library for production. In this way, the scan data can be accurately extracted and errors in manufacturing the prosthesis are significantly reduced.

The second polygon of the insertion portion 140 may be formed in the same shape as the shape recognition portion 110 and the plurality of insertion surfaces 142 and the insertion edges 144 may be formed in a plurality of outer cross- And the edges 114 in accordance with a predetermined alignment pattern. Each insert face 142 may be vertically aligned with each outer face 112 and each insert edge 144 may be positioned so that it is perpendicular to each edge 114 as shown in FIG. The insertion of the healing body 100 into the fixture 20 of the healing body 100 is performed according to the alignment pattern of the outer end faces 112 and the edges 114 even if the insertion portion 140 is moved to the insertion groove 22 and is not exposed. Direction can be confirmed indirectly. Although the outer end face 112 is vertically aligned with the insertion face 142 in the present embodiment, various modifications are possible within a range in which the insertion direction can be confirmed.

The fastening part 150 is inserted into the fastening hole 160 and a step 162 is provided at a predetermined position of the fastening hole 160 as shown in FIG. (Not shown). When the fastening part 150 is exposed to the fixture 20 and is coupled to the fixture 20, the upper surface of the fastening part 150, which is engaged with the fixture 20, The step 162 can be positioned to support the fastening portion 150. As shown in Fig. Thus, even if the fastening part 150 is exposed to the fixture 20, the inside of the oral cavity is not damaged by the healing body 100 at the time of chewing, and foreign matter such as food or therapeutic medicine remains in the fastening hole 160 I can not. Since the part of the coupling part 150 inserted into the insertion part 140 is determined by the step 162 and the insertion depth of the coupling part 150 with respect to the fixture 20 is set, It is possible to accurately extract the scan data.

The scan post 200 may be positioned on the healing body 100 through the opening 260 in order to calculate the position value of the fixture 20 and the healing body 100 in the oral cavity during the preparation of a prosthesis such as a crown. And the scan data by the scanner is extracted through the surface of the scan post 200 in a state where the scan post 200 is coupled to the healing body 100. The scan post 200 is coupled to the healing body 100 only at the time of manufacturing the prosthesis for obtaining scan data, and is separated from the healing body 100 until the prosthesis is installed.

Specifically, the scanning post 200 is disposed alternately with the concave edge 250 in the scanning post body 210 having the opening 260 and the scanning post body 210 around the opening 260, And a plurality of fixing parts 240 which are fixed by being in close contact with the protruding part 120 by the protruding part 120 and generate a coupling sound when engaged with the healing body 100.

At least the surface of the scan post 200 is formed with a matte surface, so that the scan light and the position value can be extracted without reflecting the scan light. For example, the scan post body 210 and the fixing portions 240 may be formed of a resin such as PEEK (Polyether Ether Ketone) to secure the extraction and durability of scan data.

The fixing portions 240 are formed to have a thickness smaller than that of the scanning post body 210, and can have a self-elastic force. Although three fixing portions 240 are formed in the drawing, at least four or more fixing portions 240 may be arranged in order to have a better elastic force in the area of the limited opening portion 260. Thus, the fixing portion 240 can be easily coupled to the protruding portion 120.

Due to the elastic force, the fixing portions 240 are slightly moved outward by the protrusions 120 and then are coupled to each other due to the restoring force by being lowered below the protrusions 120, 120, and the scan post 200 can be accurately seated on the healing body 100. In addition, when the fixing posts 240 collide with the protrusion 120 due to the restoring force, a coupling sound is generated when the scanning post 200 and the healing body 100 are coupled. The coupling of the scanning post 200 of a small size of several millimeters to the healing body 100 has a limitation to grasp accurately by the naked eye but can identify the correct coupling by the coupling sound.

The concave ends 250 may be formed at positions that expose the protrusions 120 between the fixing portions 240, as shown in Figs. 4A to 5B. By forming the recessed ends 250 at the above-described positions, the fixing portions 240 can be formed longer to have a good self-elasticity, and the projections of the metal material exposed by the recessed ends 250 can be reflected by the light reflection So that the correct coupling can be visually confirmed. When the scan post 200 is coupled to the healing body 100, the air remaining in the opening of the scan post 200 leaks to the outside through the concave ends 250, May be more easily combined or separated.

The scan post 200 is disposed inside the opening 260 inward of the fixing portion 240 so that the scan post 200 is not moved and fixed in a fixed position while being coupled to the healing body 100 And may further include inner sections 270 corresponding to outer sections 112, respectively.

Each inner side surface 270 can be designed to have a convex shape so as to be in contact with each outer side surface only in the central region upon joining between the healing body 100 and the scan post 200. [ As a result, the scanning post 200 is more closely fixed to the healing body 100, so that the scanning data can be accurately extracted.

5A and 5B, when the healing body 100 is inserted into the opening 260, the scanning post 200 may be provided with an opening 260 (see FIG. 5A) so that the space remains at the innermost side of the opening 260 A hollow portion 280 disposed at an inner end of the shape recognizing portion 110 and a retaining portion 282 provided at a lower portion of the hollow portion 280 to fix the upper portion of the shape recognizing portion 110. Since the hollow portion 280 is provided, air that has not leaked at the time of coupling can remain, so that the coupling is easy, and the disassembly can be performed more quickly by the air remaining at the time of separation. The hollow portion 280 is formed by thinly forming the scan post body 210 in the vicinity of the inner end faces 270 so as to apply an elastic force to the inner end face 270 and facilitate the easy coupling of the scan post 200 Contributes to separation. By providing the latching portion 282, the healing body 100 can be fixed in position without flowing in the opening portion 260. [

In addition, the scan post 200 is disposed at the outer periphery between the grip portions 220 and the grip portions 220 disposed on the outer periphery of the scan post body 210, and is provided with a healing abutment And a position indicator 230 provided to calculate a position value of the position indicator 10.

The upper edges of the scan post body 210 around the grips 220 may be formed by vertically cutting a part of the outer circumferential surface of the scan post body 210, Lt; / RTI >

The position marker 230 is a region for calculating the position value and the reference value at the time of obtaining the scan data for manufacturing the prosthesis, and is referred to when selecting the library or CAD data corresponding to the scan data. For this purpose, 220, respectively. The position indicator 230 includes a first inclined portion 232 disposed on the upper portion of the scan post body 210 and a vertical wall portion 234 disposed on the lower portion of the first inclined portion 232, A second inclined portion 224 which is formed in a curved surface having an inclination lower than that of the first inclined portion 232 with respect to a virtual plane passing horizontally through the scanning post 200 and extends downward from the lower end of the grip portions 220, (236).

In the case of the position mark made up only of the vertical wall portion 234 and the second inclined portion 236, when the operator photographs the camera of the scanner toward the upper surface of the healing abutment 10, The bent surface of the portion 236 can not be accurately recognized. The first inclined portion 232 at an angle larger than that of the second inclined portion 236 is disposed on the vertical wall portion 234 so that when viewed toward the upper surface of the healing abutment 10, The curved surface of the second inclined portion 236 can be easily seen. Further, even if the camera can not be accurately aligned on the upper surface of the healing abutment 10, the curved surface of the second inclined portion 236 can be recognized, thereby increasing the degree of freedom of photographing by the practitioner.

The second inclined portion 236 extends downward from the lower end of the grip portions 220 and has a curved end so that the second inclined portion 236 can be clearly distinguished from the grip portions 220 as a reference region at the time of obtaining scan data .

In addition, the position markers 230 are formed of a combination of cut surfaces at various angles other than a simple cut surface such as the vertical wall portion 234, so that many coordinates are given at the time of obtaining the scan data at the side, Can be accurately extracted.

4A and 4B, the position marker 230 may be provided in various shapes according to the condition of the oral cavity or the fixture 20. In addition, The CAD data matching the scan data is selected.

Hereinafter, a healing abutment according to another embodiment of the present invention will be described in detail with reference to FIGS.

The healing abutment 10a according to the present embodiment is applied to the case of manufacturing the prosthesis using the impression-making method, and includes a post 300 for pulling up for securing an impression.

Hereinafter, the same reference numerals are assigned to the same components as those of the healing abutment 10 according to FIGS. 1 to 5B, and a description thereof will be omitted, and differences will be mainly described.

The healing abutment 10a for impression preparation includes a healing body 100 that can be engaged for a predetermined period of time to form an aesthetic gum on the fixture 20 that is articulated to the alveolar bone and healed to apply the impression for making the prosthesis, And a pull-up post 300 detachable on the body 100.

Like the healing abutment 10 according to FIGS. 1 to 5B, the healing body 100 includes a shape recognition unit 110, a protrusion 120, a column unit 130, an insertion unit 140, And a fastening part 150 inserted through the fastening part 160.

The pulling post 300 is alternately arranged with the concave end 350 in the pull body post body 310 having the opening 360 and the pull body post body 310 around the opening 360, And a plurality of fixing portions 340 that are fixed by being in close contact with the protruding portion 120 by the protruding portion 120 and generate a coupling sound when engaged with the healing body 100.

The fixing portions 340 are formed to have a thickness smaller than that of the post body 310 for pulling up and have self-elasticity. Although three fixing portions 340 are formed in the drawing, at least four or more fixing portions 340 may be arranged in the area of the limited opening portion 360 so as to have a better elastic force. This makes it possible for the fixing portion 340 to easily engage with the protruding portion 120.

The pulling post 300 can be accurately seated in the healing body 100 by the elastic force and the restoring force of the fixing portions 340 and when the heeling body 100 is joined with the post 300 for pulling up the impression A joint tone can be generated to identify the correct combination.

The concave ends 350 may be formed at positions that expose the protrusions 120 between the fixing portions 340, such as the concave ends 250 of Figs. 1 to 5B.

The pulling post 300 is disposed on the inner side of the fixing portion 340 in the opening 360 so that the pulling post 300 is not moved and fixed in the fixed position while being coupled to the healing body 100 And may further include inner sections 370 corresponding to outer sections 112, respectively. Of course, each inner section 370 can be designed to have a convex shape in contact with each outer section only in the central region upon engagement between the heeling body 100 and the pulling post 300.

8, when the healing body 100 is inserted into and joined to the opening 360, the post 300 is formed so that a space remains in the innermost portion of the opening 360, A hollow portion 380 disposed at the inner end and a retaining portion 382 provided at the lower portion of the hollow portion 380 to fix the upper portion of the shape recognition portion 110. The hollow portion 380 and the engaging portion 382 have substantially the same function as the hollow portion 280 and the engaging portion 282 shown in Figs. 1 to 5B.

In addition, the impression preparation post 300 is disposed below the impression coping section 330 and the impression coping section 330 provided on the post body 310 for pulling up to obtain an impression And may further include grippers 330.

The healing abutments 10, 10a according to Figs. 1 to 8 can simplify the manufacture of the prosthesis by performing the scanning process or the impression making process without separating the healing abutment from the fixture during the implant procedure.

In addition, the number of times of attachment / detachment of the healing abutments 10, 10a is reduced, and the loss of the alveolar bone or the like of the patient is lowered, so that rapid healing is possible and convenience for the physician can be improved. In addition, since the attachment period of the gingiva and the healing abutment 10, 10a is prolonged, a fundamental healing function can be stably performed.

Hereinafter, a description will be given of performing scanning of an implant procedure by applying a healing abutment according to an embodiment of the present invention, with reference to FIGS. 1 to 5B and FIG. 9 is a view showing an example of application of a healing abutment according to an embodiment of the present invention to implant surgery.

First, the practitioner places the fixture 20 on the alveolar bone of the patient, confirms the degree of osseointegration, and tightens the healing body 100 of the healing abutment 10 to the fixture 20 for esthetic gingival formation . The healing body 100 is stably fixed in the correct position of the fixture 20 through the coupling part 150 and the insertion depth and the coupling direction are determined by the corresponding polygonal insertion part 140 and the insertion groove 22. [ So that accurate scanning data can be obtained. Through the aligned pattern between the shape recognition unit 110 and the insertion unit 140, the practitioner can advance the joining of the healing body 100 while confirming the joining direction of the healing body 100 to the fixture 20 have.

Next, when performing a scanning process for fabricating the prosthesis, the scan post 200 is coupled to the upper part of the healing body 100. It is possible to confirm whether or not the binding for the scan post 200 is normal by listening to the binding sound generated when the scanning post 200 is coupled with the protruding portion 120 by the fixing portion 240 having elasticity. In addition, the practitioner can visually check the protrusion 120 exposed by the concave ends 250 to determine whether or not the protrusion 120 is normally engaged. In addition, due to the convex shape of the inner end face 270 corresponding to the outer end face 112, the scan post 200 does not flow in the inserted state of the healing body 100, and can be fixed more tightly .

The practitioner scans the inside of the mouth with the scanner 30 in a state where the scan post 200 is coupled to the healing body 100 to extract the three-dimensional scan data. Since the post-body 210 of the scan body formed of resin is provided with the matched surface and the position markers 230 in which the cut surfaces at various angles are combined, accurate scan data can be secured. The height, width, dentition, occlusion state and the relationship between the jawbone of the patient and the surrounding teeth at the position where the implant is to be performed, and the like are determined through the scan data acquired by the healing abutment 10 according to the present embodiment Accurate data can be obtained.

Next, after acquisition of the scan data, the scan post 200 is separated from the healing body 100, and the patient holds the healing body 100 while being held in the fixture 20.

On the other hand, the extracted scan data is provided to the CAD cam apparatus to inversely calculate the position, inserted depth and direction center coordinates of the fixture 20 and the healing abutment 10, and the prosthesis is designed And processed. The healing abutment 10 according to the present embodiment recognizes the surface data of the scanning post 200 and calculates the length of the healing abutment 10 so that the orientation of the fixing hole of the fixture 20 and The angle of inclination, and the like can be accurately calculated. Based on this, the prosthesis is manufactured using the CAD cam apparatus.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, I will understand. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by all changes or modifications derived from the scope of the appended claims and the appended claims.
