Description

Stepless mounting implant in the alveolar bone fixation hole and its method

The present invention relates to a non-step-mounted implant in the hole for fixing the alveolar bone and a method of treating the alveolar bone. More specifically, when permanent teeth are damaged and implanted artificial teeth are implanted in the alveolar bone of the corresponding area, the fix is fixed. The implant is invented so that the implant can be easily and firmly buried in a short time without the need for forming a separate fixture coupling tab (i.e. thread) for screwing the fixture into the inner surface of the fixture mounting hole. The present invention relates to a non-step (ie, no screw step) mounting type implant in an alveolar bone fixation installation hole so that the fixture can be installed without forming a screw thread in the alveolar bone fixation hole, and a method of treating the same.

In other words, the present invention is a crescent hang of a detachable fixture formed with a screw only on the inner surface of both sides of the bottom of the fixture installation hole in order to embed artificial teeth in the alveolar bone of the permanent tooth damaged area When the plate is fitted, it forms an arc-shaped locking groove, and when installing the artificial tooth coupling fixture, it does not form a separate fixture coupling step (i.e., a thread) in the hole for fixing the fixture. The pair of detachable fixtures having an arc shape of 4 are inserted to face each other so that the crescent-type locking plate is fitted into the arc-shaped catching grooves, and between the pair of detachable fixtures, a thread is formed on the inner surface and is flat. The bottoms of the pillars each having a quarter-circle shape are inserted into the integral fixture connected integrally through the disk. The pair of detachable fixtures and integral fixtures form a cylindrical shape, and are then integrally fixed to the artificial tooth on the threads in the pair of detachable fixtures and integral fixtures having a cylindrical shape by mutual coupling. The combination of screws allows the implant procedure to be completed, dispersing the cyclic load at the end of the disc during food mastication to extend the life of the implant, as well as the detachable fixtures and integral fixtures and anchors. The tightening force by the screwing method of the butt can reduce the depth of the hole for installing the implant, so that there is no need for artificial bone graft when the maxillary sinus augmentation is performed, and in the case of the mandibular molar, the fixation of the alveolar bone can be minimized. The present invention relates to a stepless installation implant in an installation hole and a method of treating the same.

In general, implant refers to the meaning of implantation, and is used to substitute for reconstruction and function of a form by implanting artificial or natural material into a defect to compensate for a defect in biological tissue. It refers to materials (printing machines) or implantation, and artificial valves, artificial joints, artificial roots, intraocular lenses, etc. are well known.

These implants have little pain or movement and feel like their teeth. The amount and quality of the bones can be over 80 years old.

Previously, artificial crowns or bridges, embedded partial dentures or full dentures have been used to recover when teeth are missing. There was a problem of shaving healthy teeth next to them to securely replace these substitutes.

It is not possible to make this missing root by the above method, so that the missing bone is absorbed, and the shape becomes poor, or as time passes, the bone amount decreases, so the denture is not exactly right, so it is often painful every time you chew. Loss of pleasure leads to loss of one's daily life and social life, and mental burden is often increased.

Implants are a treatment that solves these problems. Because they do not move like dentures and are fixed, they feel like teeth. Dentures are uncomfortable because the gum hurts or the teeth are unstable every time you chew. There can be almost no this.

In addition, you can find a natural appearance or facial expression to restore confidence in front of people and restore the ability to chew, so you can eat a balanced diet.

Most of the conventional implants used to implant such artificial teeth consist of a fixture, an abutment and a screw, and the fixture is inserted into the alveolar bone where the permanent tooth is damaged. And an abutment to which an artificial tooth is fixed on the upper portion of the fixture, and coupled to the fixture by fastening the abutment to the fixture. Join to the top.

At this time, the fixture is formed with a screw thread to be inserted into the hole formed in the alveolar bone on the outside, the upper end is formed of a hexagonal head, the fastening hole formed with a screw thread of the screw in the upper surface is formed vertically have.

In addition, the abutment is formed so that the lower inner surface is located above the fixture to insert the head of the fixture, the inside is formed hollow so that the artificial teeth can be inserted, fixed.

In this way, the fixture with a thread formed on the outside is fastened to the alveolar bone to be integrated, and the abutment is positioned on the upper portion of the fixture, wherein the upper outer side of the fixture and the lower inner side of the abutment are mutually Since it is formed in a hexagon, the abutment located at the top of the fixture does not rotate.

 The abutment is fixed to the fixture by penetrating the screw into the abutment so that the thread of the screw is fastened to the fastening hole of the fixture.

In this way, the implant consisting of the fixture, the abutment and the screw is fixed to the alveolar bone of the damaged tooth position, and the artificial tooth is coupled to the fixed abutment to implant the damaged permanent tooth of the patient with the artificial tooth.

Of course, in recent years, various implants having another shape in addition to the implant having the above-described configuration have been proposed, but most fixtures have a screw form in which threads are formed on the outer surface thereof.

Therefore, when you want to perform an implant procedure for implanting an artificial tooth into the alveolar bone at the site where the permanent tooth is damaged, the fixture is forcibly coupled to the fixture installation hole formed in the alveolar bone using a drill, and automatically fixed to the inner surface of the fixture installation hole. The thread is formed, and the fixture itself is screwed into the hole.

However, the permanent tooth is damaged as described above, and the fixture is forcibly coupled to the fixture installation hole formed in the alveolar bone to implant the artificial tooth, and the artificial tooth is implanted using the implant while automatically forming a thread in the inner surface of the fixture installation hole. In this case, the direction of the cyclic load at the time of food mastication is directed toward one point, which is the lowest cross section of the screw type fixture, and has a relatively short lifespan of about 5-10 years.

In addition, in order to form or automatically form a screw thread on the inner surface of the fixture installation hole, it is usually necessary to fix it to a depth of 8-13 mm to facilitate the fastening. In the process, the time taken for the union of the damaged alveolar bone surface and the fixture becomes longer. In the process of fixing the fixture to secure sufficient depth, the risk of touching the mandibular nerve increases in the case of the mandibular molar (molar) .In case of the maxillary sinus augmentation, sufficient depth cannot be secured. There is also a problem in that the risk of sinus perforation during the procedure increases.
