Description

[0001] The present invention relates to a healing abutment having a scan body function,

The present invention relates to a healing abutment having a scan body function, and more particularly, to a healing abutment having a scan body function capable of easily manufacturing a prosthesis.

Japanese Patent Application No. 10-1199203 discloses a scan body for a scan device for manufacturing a prosthesis and a method for manufacturing a prosthesis using the same.

As disclosed in the patent, a conventional prosthetic manufacturing method first places a fixture on a patient's gums through a primary operation. Then, the healing abutment is tightened through the second operation. Next, a personal tray is manufactured. Impression is acquired by using imprint coping using the created personal tray. Then, a model is manufactured using analog, and a scan jig is attached to the model for scanning. After the design work on the scan data, the abutment is processed and completed.

In other words, in the conventional method of manufacturing the prosthesis, the healing abutment is removed, the implantation copings are connected, the implant is re-imposed, the model is operated using the analog, and the scan jig is mounted again and scanned. Therefore, conventionally, there is a problem that the manufacturing process of the prosthesis becomes long and complicated because the healing abutment is removed and the implantation is performed in order to perform scanning.

The present invention is intended to solve the above problems. SUMMARY OF THE INVENTION It is an object of the present invention to provide a healing abutment having a scan body function in order to simplify the production of a prosthesis.

The healing abutment with the scan body function according to the present invention includes body means and screw means. The body means includes a fixture engaging portion formed in a polygonal shape to be inserted into a fixture and prevented from being rotated, and a body portion formed on an upper portion of the fixture engaging portion so as to be exposed to the outside so that the prosthesis can be mounted. A penetrating through-hole is formed. The screw means may have a threaded portion at one end and may be screwed to the fixture by the threaded portion to be inserted into the through hole of the body means and fix the body means to the fixture. Here, the body portion is formed with a scan jaw on one side of the upper portion exposed to the outside so that a cut surface parallel to the one direction of the fixture engaging portion formed by the polygon is formed.

Further, in the above-described healing abutment, it is preferable that the screw means has an identification groove formed at the other end thereof so that the length of the body portion can be known.

In the above healing abutment, it is preferable that the cut-off surface has four corners.

In addition, in the above healing abutment, the length of one side of the cut-off surface may be formed at a predetermined ratio with the diameter of the body portion.

In addition, in the healing abutment, the body may be formed with a fitting groove along the circumferential direction beneath the scan jaw. In this case, the healing abutment further includes lid means inserted in the fitting groove so as to cover the upper portion of the body portion so that the gums do not cover the body means.

In the above healing abutment, it is preferable that the scan jaw is formed within a range of 2 mm or less from the upper end of the body part.

According to the present invention, the orientation of the fixture and the length of the body of the healing abutment can be determined using the healing abutment. So you can scan the healing abutment to create an abutment. Therefore, it is possible to reduce the manufacturing process and manufacturing period of the prosthesis.

One embodiment of a healing abutment according to the present invention will be described with reference to Figs.

The healing abutment according to the invention comprises a body means (10) and a screw means (20).

The body means 10 is formed with a through hole 17 penetrating in the axial direction and has a fixture engaging portion 11 and a body portion 13. The fixture engaging portion 11 is formed in a polygon so as to be inserted into the fixture and prevented from rotating. It is generally formed as a hexa-shaped figure with six sides. The body part 13 is formed on the upper part of the fixture engaging part 11 and is exposed to the outside so that the gums are engaged when mounted on the fixture and the prosthesis is mounted on the upper part. At this time, a scan jaw 14 is formed at the upper end of the body part 13 so that the fixture can be grasped. The scan jaw 14 should be formed within a range of 2 mm from the upper end of the body portion 13 since it must be exposed to the outside when the body means 10 is coupled to the fixture. This is because if the scan jaw 14 is formed below 2 mm at the upper end of the body section 13, it may be buried in the gum. The scan jaw 14 has a cutout surface 15 on one side of the upper end of the body portion 13 to detect the direction of fixture placement. The cutting face 15 has four corners and is formed parallel to the same direction as any one of the six faces 11a of the fixture engaging portion 11. [ In this case, since the incision surface 15 has four corners, when the scanner is scanned, the four corners are scanned, and the direction of the incision surface 15 is grasped. Therefore, the direction of the fixture engaging portion 11 can be known because it can be recognized in the direction of the incision surface 15, so that the direction of the fixture can be known. The incision surface 15 is formed such that the length of one side 15a is in a constant ratio with the diameter of the body 13. Thus, if the length of one side 15a is known, the size of the diameter of the body 13 can be known.

The screw means 20 is inserted into the through hole 17 of the body means 10 and serves to fix the body means 10 to the fixture. To this end, the screw means 20 is formed with a threaded portion 21 at one end thereof. That is, when the screw means 20 is inserted into the through hole 17 of the body means 10 and screwed into the fixture with the screw portion 21, the body means 10 is fixed to the fixture. At the other end of the screw means 20, an identification groove 23 is formed so that the length of the body portion 13 of the body means 10 can be known. For example, if the identification groove 23 is one, the length of the body portion 13 is 6 mm, and if the number of the identification grooves 23 is two, the body portion 13 is 8 mm, and if three, the body portion 13 is 10 mm, Can be determined. Thus, the length of the report body 13 can be known from the other end of the screw means 20. [

In the healing abutment of the present embodiment, a scan jaw 14 is formed on the body means 10 so that the fixing direction and the tilting angle of the fixture can be determined. The length of the body portion 13 is set in the screw means 20 An identification groove 23 is formed to indicate the depth of the fixture in the gum, thereby serving as a scan body.

A method of fabricating an upper prosthesis using the present embodiment first performs a primary operation for placing a fixture on a patient's gums. Then, the healing abutment of this embodiment is mounted through a secondary operation. That is, after the body means 10 is inserted into the fixture, the screw means 20 is fastened to mount the healing abutment. In this case, since the scan jaw 14 is exposed to the outside of the gum, the orientation of the fixture can be determined through the scan jaw 14. That is, the cut surface 15 of the scan jaw 14 is the direction in which the fixture is placed. The length of the body portion 13 can be determined through the identification groove 23 formed in the upper portion of the screw means 20. In this case, since the length of the exposed gums is measurable, the depth of the gums can be determined by subtracting the length of the gums from the length of the body portion 13 sensed through the discrimination groove 23. That is, how deeply the fixture is inserted.

After installing the healing abutment, make the impression model. Scan the fabricated impression model. At this time, since the impression model is lifted off the pattern of the healing abutment exposed to the outside of the gum, not only the incision surface 15 of the scan jaw 14 is formed in the impression model but also the identification groove 23 of the screw means 20, . Since the incision surface 15 is composed of four corners, four corners are measured at the time of scanning, so that the inclination and the direction of the fixture can be grasped by using the four corners measured. On the other hand, since the length of one side of the incision surface 15 is formed to be proportional to the diameter of the body portion 13, the diameter of the body portion 13 can be known by knowing the length of one side using the scanning data. In addition, since the length of the body portion 13 is known from the identification groove 23 measured in the scanning data, and the length of the healing abutment exposed to the gum in the impression model is scanned, The depth of the body portion 13 can be known.

Therefore, all the information of the abutment is obtained from the scanning data, so the abutment can be processed using this information.

Therefore, when the present embodiment is used, it is possible to carry out steps of fixing fixture, mounting healing abutment, making an impression model, model scanning, and abutment processing with scanning data when manufacturing the prosthesis. Therefore, it is possible to process abutments by a simple process.

Another embodiment of the healing abutment according to the present invention will be described with reference to Fig. In the healing abutment according to FIG. 8, a fitting groove 16 is formed in the body portion 13 of the body means 10. And cover means (30).

The fitting grooves 16 are formed along the circumferential direction under the scan jaws 14.

The cover means 30 is inserted into the fitting groove 16 so as to cover the upper end of the body portion 13 so that the gums do not cover the body means 10. In other words, the lid means 30 is provided with a fitting projection 31 which can be inserted into the fitting groove 16, and is mounted on the body portion 13.

When a healing abutment is attached to a fixture, the gums grow and cover the healing abutment. Since the lid means 30 is mounted on the top of the body portion 13, it is possible to prevent the gum from covering the healing abutment.

On the other hand, the fixture may not be centered depending on the condition of the patient's gums, but may be biased toward one side and eccentrically placed. In this case, if the shape of the covering means 30 is appropriately formed, the gums can be induced to be esthetically formed irrespective of the eccentricity of the fixture, so that the abutment can be formed in an ideal shape. Of course, in this case, when the impression model is manufactured, the lid means 30 is removed to fabricate the impression model.

Therefore, by using the present embodiment, it is possible to perform the scanning operation immediately after the installation of the healing abutment and by producing the impression model. Therefore, it is possible to reduce the manufacturing steps and the manufacturing period of the prosthesis.
