Description

{Discriminating the direction and location of fixture healing abutment}

The present invention relates to a directional and positionally identifiable healing abutment of a fixture, and more particularly, to a fixture that can identify the directionality and position of a fixture without removing the body portion from the fixture through the display portion And location-identifiable healing abutments.

In general, teeth play a role in helping digest food well by crushing or grinding. If these teeth are lost, the food can not be chewed properly and the digestion is not easy, so that not only the food can be freely consumed, but also the nutrient intake is difficult. Thus, teeth have been recognized as an important part of the body since ancient times, and play an important role in maintaining a healthy life.

Since human teeth are replaced with permanent teeth once in childhood, new teeth are not created when teeth are lost. Therefore, dentistry restores lost teeth and surrounding tissues through prosthetic treatment, .

However, this general dental treatment method can not be tolerated because it causes some damage to adjacent teeth, surrounding gums, and bone tissue. If dentures are used, it will lead to a reduction in chewing ability In addition, it had disadvantages such as discomfort or foreign body sensation.

An artificial tooth implantation method has been proposed to overcome the drawbacks of this universal prosthetic treatment method. According to this method, it is possible to restore all functions and appearance almost the same as a natural tooth without damaging surrounding teeth or tissues when a tooth is defective.

In this way, the implants that have been spotlighted in the recent years can be used as artificial alternatives to natural teeth by providing an artificial tooth by osteosynthesis in the alveolar bone. Implants generally consist of three parts: fixtures corresponding to artificial teeth, abutments corresponding to abutments, and artificial teeth. A fixture is a fixture that is implanted in the alveolar bone of a missing tooth area like the root of a natural tooth to support an artificial tooth. The abutment is also called an abutment tooth, which is attached to the gum to connect the fixture, which is planted in the alveolar bone, to the artificial tooth.

Artificial teeth are fixed in the oral cavity by abutment and are designed to reproduce the same shape and function as natural teeth.

The implantation process for recovering lost teeth using such an implant is as follows.

The transplantation process is largely divided into surgical procedures, ie, surgical procedures and prosthodontic restorations. Basic tests such as blood tests are performed to check compliance before surgery, and the site of bone grafting In order to evaluate the amount, oral examination and radiographic examination are preceded. After this series of examinations are completed, they are entered into a surgical procedure called primary surgery. First, in order to implant a fixture corresponding to the root in the alveolar bone under anesthesia, the gums are dissected, the alveolar bone tissue is exposed and the fixture is inserted Cover the fixture with a lid and suture once.

However, the conventional fixture is mainly formed in a cylindrical shape or a rounded root-like shape, and the shape and size of the cutting edge are processed to a constant size irrespective of the diameter or length of the implant. And it is troublesome to enlarge the alveolar bone sufficiently by using the cutting tool. As a result, it is difficult to obtain a strong initial fixation force with the alveolar bone, so that the root waits for 2 to 4 weeks before it comes into fixture.

Then, for the second operation, the gums are cut again, the cover is removed, the gums surround the outer circumference of the artificial teeth, and the healing abutment for the formation of the aesthetic gums Fix it to fixture and wait for two months.

Then, an impression according to the oral structure is made to produce an artificial tooth. In order to make an impression, first, the healing abutment is removed from the fixture, and then the impression cap is fixed to the fixture. Then, impression is made using impression material.

After the impression is made, remove the fixed impression cap to make the impression, fix the healing abutment to the fixture again, and wait until the artificial tooth is completed.

In this case, it takes about 30 minutes to 1 hour for the step for impression preparation, that is, the step of fixing the healing abutment removed from the removal of the healing abutment to the fixture, and the time is further increased according to the number of implants .

As described above, after the artificial tooth to be inserted into the implant treatment position is manufactured through the impression preparation, the implant treatment is completed by removing the healing abutment and fixing the abutment and the artificial tooth.

In this conventional implant treatment, in particular, for the impression taking, it takes about 30 minutes to 1 hour from the removal of the healing abutment to the fixing of the healing abutment. Even if one implant treatment is performed, And thus, there is a problem in that the operation time is wasted and the operation procedure is difficult and the operation is difficult.

The reason why the impression cap is inserted through the impression cap is to make the artificial tooth by grasping the directionality of the fixture.

In addition, when the impression cap is fixed by inserting the impression cap into the fixture as in the conventional method, an error may occur due to a change in the directionality and the position, so that the manufactured abutment and the artificial tooth may not be suitable for the patient , There is a problem that the implant treatment time is prolonged.
