Description

DIGITAL HEALING ABUTMENT [0002]

The present invention relates to a healing abutment which is bonded to a fixture placed on a gum during a dental implant treatment and which heals the gum in a shape corresponding to the cervical portion during healing of the gum More specifically, it can be fixed to a fixture with directionality, but prevents foreign matter from entering the inside of the healing abutment and the fixture while the gums are healing. And a digital healing abutment which enables a more precise and rapid implant treatment by allowing the user to present a reference point during a scan for the manufacture of a prosthesis

In general, the primary purpose of dental prosthodontic treatment is to restore the function of patients who have difficulty in chewing, pronouncing, or eating food by damaging or losing their teeth. In animals, teeth may be the primary means of attack, Typical functions are authoring and pronunciation. In other words, in order to ingest nutrition by digesting food through peristaltic motion and segmental motion in the internal organs, the teeth are crushed in the oral cavity to make a proper size to be mixed with the saliva, To adjust the flow to help you pronounce the correct pronunciation.

If you do not have teeth, you will not be able to grind food properly and you will always have to eat only liquid foods. Therefore, proper nutritional supply will be difficult and the body will be in a helpless condition with no power, and the immune status will deteriorate and the resistance to disease will be lowered and sometimes it will be in serious condition. In addition, since proper stimulation is not given to the ridge, when the lower alveolar bone is gradually absorbed and disappeared, the deformation of the face will come and the vicious circle of the worse situation will wait. If there is no tooth in the pronunciation, it is impossible to pronounce the correct pronunciation because the air can not be controlled through the oral cavity. It is obvious that it will be a big obstacle to social life such as deterioration of physical health, passive interpersonal relationship and depression caused by it. Therefore, it is difficult to say that dental prosthesis is a perfect solution to all of the above problems, but it is clear that it can play a big role indeed.

One of these dental prosthetic treatments, the implant procedure, can be various. The implant procedure described below is a fixture level impression method in which a model in the oral cavity is completed by connecting impression copings in the oral cavity when the impression is made during the prosthesis process.

First, drilling and tapping are performed on the to-be-formed bone to form a groove conforming to the dimension of the fixture, and a mount is fastened to the top of the fixture. Then, using a surgical handpiece, the fixture and mount are inserted into the alveolar bone, and then the mount is removed from the fixture, thereby implanting the fixture 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 oral cavity from entering 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 unilaterally 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. For aesthetic gingival formation, the healing abutment is fastened to the top of the fixture and waited for two to three weeks. In order to improve the complexity of such a second procedure, a first-aid procedure, in which the procedure of fastening and removing the cover screw is omitted, is used to fasten the abutment abutment.

Next, after confirming the esthetic gingival formation, remove the abutment abutment, and fasten the impression coping on 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 top of the fixture, and an artificial tooth is completed by fixing a prosthesis or artificial crown on the abutment.

In this way, a healing abutment is generally used for the aesthetic gingival formation during the implant procedure.

For example, Korean Patent Laid-Open No. 10-2009-0110136 discloses a "healing abutment of an implant structure having a healing cover ".

The present invention is characterized in that the healing cover is coupled to the fixture immersed in the alveolar bone to combine the abutment and to cover the outer surface exposed to the outside of the abutment of the abutment.

However, in the above patent, the healing cover can be further provided, but it can be completed through a complicated process with a completed technical idea, and furthermore, a manufacturing process of the corresponding cover is further demanded, and the problem that the procedure period of the implant is eventually increased This can be.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings, in which: FIG.

As shown in FIGS. 1 to 3, the fastening means 200 penetrating through the hollow portion 102 formed through the upper and lower portions of the inner space of the present invention is screwed to the fixture 300, which is placed in the alveolar bone, In abutment,

A hollow portion 102 formed through the upper and lower portions as an internal space, a connection portion 110 which is inserted into the fixture and has a polygonal cross section, a support portion 112 which protrudes in the circumferential direction at the connection portion and guides the shape of the gum while the gum is healed A holding part 130 protruding in a circumferential direction from the supporting part to prevent the shape of the gum from coming up over a certain distance, an outer shape part 140 extended from the holding part to a diameter larger than the holding part, A groove 150 that is formed to be depressed downward from one end of the outer contour so as to confirm the vertical data of the Z axis at the time of scanning, a direction indicator 160 formed by cutting on the other side of the outer contour on which the groove is formed, And a plurality of information confirmation grooves 170 that are arranged at equal intervals along the circumference of the cross section in contact with the direction designating section.

In detail, in the healing abutment 100 according to the present invention, the diameter of the outer contour 140 can be enlarged or reduced according to the distance between the teeth, and the diameters of the supporting part 120 and the holding part 130 may be different It is natural to be able to. Therefore, the preferred embodiment will be described in detail.

The supporting unit 120 and the holding unit 130 are configured to naturally form the shape of the gum while the fastening unit 200 penetrates the hollow part 102 and is engaged with the fixture placed on the gum to heal the gum, .

At this time, since the holding part 130 is formed at an angle of 10 ° to 20 ° more inclined than the supporting part 120, it is possible to prevent the gum from rising up above a certain distance due to inflammation or swelling, And the load applied to the fixture 300 can be dispersed due to the chewing motion caused by the ingestion of food by the patient.

Particularly, the groove 150 can be formed to be erected upright on the outer circumferential surface of the outer shape part 140, that is, to correspond to the shape of the patient's mouth, When the recess 150 indicates the vertical data of the Z axis, an accurate reference point can be obtained and a coordinate value can be obtained when the prosthesis is manufactured.

In other words, a description of a conventional implant procedure will be described step by step. A personal tray in the oral cavity is prepared, a fixture is inserted, and after impression coping is combined, an impression is made and the position of the fixture in the mouth is reproduced in the corresponding impression coping In order to attach a lab analog to the lap analog rod, cast a stone (soft resin) into the lapel analog rod and cast the shape of the lap analog rod by injecting a stone. After manufacturing the lab analog, the abutment is combined with the fixture In the method of covering, there is a long working time, expense due to consumption of materials expands, and lab analog errors are generated at the impression making stage, so that the same restorative material as the patient's mouth shape is manufactured. I did not get it. In order to positively solve all the problems, the present invention can acquire information of the Z-axis through the groove 150 in the impression-taking step so that an accurate reference can be secured, and even in a small laboratory without a scanning device, A reference shaft can be obtained through the recognizable groove 150 to produce a precise prosthesis. A reference axis can be obtained in a case where a high esthetic and accurate prosthesis is manufactured through a scanning operation with a scanning device. Accordingly, since the implant prosthesis can be manufactured at low cost without the need for a scan device, it is possible to obtain the effect of reducing the cost of the implant treatment of the patient while promoting the development of the laboratory.

In addition, the recess 150 may be used for other purposes, i.e., the working means may be combined to allow the position of the digital healing abutment 100 in the oral cavity to be maintained clean , And the effect of preventing the infection by shifting to the hands of the operator is also obtained.

In addition, when the fastening means 200 and the fixture 300 are screwed together, the fastening means 200 and the fixture 300 are formed in the same line as a part of the end face of the connection portion which is inserted into the fixture together with the fastening means, The direction indicator 160 may be formed on the horizontal plane and the cross section of the display unit 110 in the same manner. In other words, the connection portion is inserted into the fixture due to the fastening means, that is, the polygonal cross section of the connection portion has a polygonal cross section, and the cross section of the connection portion and the cross section of the fixture are engaged with each other The information corresponding to the position where the fixture is placed, the direction in which the fixture is placed, and the like are exposed to the outside due to the direction indicator disposed on the same horizontal line as the cross section of the connection portion, A criterion can be provided that can be produced in a direction corresponding to the shape of the teeth of the user. In addition, the digital healing abutment 100, which is miniaturized, can be clearly identified by the operator due to the stepped shape at the lower side of the direction instructing section 160.

More specifically, as shown in FIG. 4, the fastening means 200 is formed by a length of the hollow portion 102, and is formed with a diameter corresponding to the diameter of the hollow portion, (230) may be further configured. In other words, the entry preventing portion 230 is formed so as to correspond to the distance and diameter of the hollow portion 1020, and is interlocked with each other, so that the patient is guided into the fixture placed on the gum due to the chewing motion for consuming food It is possible to prevent foreign matter from entering the hollow portion 102 of the healing abutment and to prevent foreign matter from flowing into the hollow portion 102 of the healing abutment. In addition, it will be appreciated that the fastening means 200 is formed with the threaded portion 210 to be screwed with the fixture 300. In addition, a fastening screw portion 103 may be further formed in the internal area of the digital healing abutment so that the fastening means and the digital healing abutment 100 are tightly coupled with each other. This means that the fastening means 200 is ultimately provided with the fixture 300, which is placed on the gums, before being completely screwed, so as to maintain the tight coupling between the fastening means and the corresponding digital healing abutment, It is possible to positively improve the lateral flow of the abutment.

In addition, the number of the information confirming grooves 170 may be set and depressed according to the details of the length of the digital healing abutment 100 and the like. In other words, in order for the length of the digital healing abutment to be known due to the number of depressions of the information confirming groove 170 without the need for a separate dimension checking procedure for the corresponding healing abutment, the corresponding digital healing abutment (1 to 8) are set in advance according to the length of the substrate (100). The length of the fastening means 200 and the distance and diameter of the entry preventing portion 230 can be set in accordance with the length of the digital healing abutment 100, It is possible to perform the implantation procedure more quickly by allowing the confirmation groove 170 to be set in advance.

The above configuration is an internal type of the digital healing abutment 100 according to the present invention in which the connection part 110 is inserted into a hole formed in the area of the fixture 300 and is fastened by the fastening means 200 So that the digital healing abutment 100 can be fastened with the screw.
