Description

TECHNICAL FIELD [0001] The present invention relates to an implant and a method of implanting the same in a hole for mounting an alveolar bone in a fixture,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an implantless implant in a fixture mounting hole of an alveolar bone and a method of performing the same, and more particularly, to a method of implanting an artificial tooth using an implant on an alveolar bone, It is possible to easily and firmly implant the implant within a short period of time without performing an operation of forming a separate fixture attachment step (i.e., thread) for screwing the fixture to the inner surface of the hole for installing a fixture The present invention relates to an implantable implant (not to be screwed into a screw) in a fixture mounting hole of an alveolar bone that can be installed without a screw thread in a fixture mounting hole of the alveolar bone, and a method of performing the same.

In other words, according to the present invention, a fixture mounting hole is drilled in order to insert an artificial tooth into an alveolar bone of a damaged part of a permanent tooth, and a crescent-shaped catch of a detachable fixture having threads formed on both sides of the bottom surface of the fixture mounting hole, (Not shown) is formed in the fixture mounting hole at the time of installing the fixture for artificial tooth bonding, and the flat surface is simply formed into a 1 / 4 type circular fixture having an arcuate shape is inserted so as to face each other so that the crescent-shaped locking plate is engaged with the arc-shaped locking groove, and a thread is formed on the inner surface between the pair of detachable fixtures, Insert the integral fixture integrally connected through the disc to the bottom of the column having a quarter-arc shape A pair of detachable fixtures and an integral fixture are formed into a single cylindrical body, and then the pair of detachable fixtures having a cylindrical shape by mutual engagement and the detachable fixture integrally fixed to the artificial teeth with threads in the integral fixture The implant can be completed by bonding the screws so that the durability of the implant can be prolonged by dispersing the disk-shaped lower end portion of the repeated load during mastication (mastication), and the detachable fixture, the integral fixture, In order to minimize the risk of damage to the nerve part in the case of mandibular molar, artificial bone grafting is not required in the case of performing maxillary sinus elevation because the depth of the hole for installing the implant can be reduced by strengthening the binding force by the screw- Mountable implant in an installation hole and a method of performing the same.

Generally, implant refers to the meaning of transplantation. It is used when implanting artificial material or natural material into a defective part in order to compensate for deficiency of a living tissue to perform reconstruction and function of the shape Refers to a material (artificial organ) or graft, and artificial valves, artificial joints, artificial roots, guide lenses and the like are well known.

Implants such as these can be painful or almost impossible to move and can be 80 years old or older if they are of the same quality and quality as their own teeth.

Previously, artificial crowns or bridges, interlocking partial dentures or full dentures were used to restore the tooth when it disappeared. To fix this substitute, there was a problem of shaving the healthy tooth on the side.

In the above-mentioned method, since the missing root can not be made, the bone of the missing part is absorbed and the shape is not good, or the amount of bone is decreased as time goes by, so that the denture does not fit correctly, I lost my pleasure and lost myself in everyday life and social life, and I was often mentally burdened.

Implant is a treatment that solves these problems. It does not move like a denture and is fixed. Therefore, it feels like a magnetic tooth. Denture has inconvenience because it has gum pain or instability every time it chews. However, It is almost impossible to say.

In addition, you can find a natural appearance and expression, restoring self-confidence in front of people, restoring chewing ability, and not being affected by the type of food, so you can have a balanced meal.

Most of the conventional implants used for implanting such artificial teeth are composed of a fixture, an abutment, and a screw. The fixture is used to insert a hole into an alveolar bone at a damaged portion of a permanent tooth The screw is engaged with the fixture through the attachments while the attachments to which the artificial teeth are fixed are positioned on the upper part of the fixture, and the attachments are fixed to the fixture .

At this time, the fixture is formed with a thread to be inserted into the hole formed in the alveolar bone to be coupled to the outside of the fixture, a hexagonal head is formed at the upper end, and a fastener having a screw thread formed inward is formed vertically have.

In addition, the lower end of the attachment is located at the upper part of the fixture and is formed to be able to insert the head of the fixture, and the inside is formed hollow so that the artificial tooth can be inserted and fixed.

In this case, the fixture having the screw thread formed on the outer side is fastened to the hole of the alveolar bone so that the fixture is integral with the fixture, and the upper end of the fixture is positioned on the upper side of the fixture. Since the hexagon is formed, the abutment located at the top of the fixture does not rotate.

Here, the screw is passed through the interior of the attachment, and the thread of the screw is fastened to the fastener of the fixture, thereby fixing the attachment to the fixture.

In this manner, the implant consisting of a fixture, an attachment and a screw is fixed to the alveolar bone at the damaged tooth position, and the artificial tooth is fixed to the fixed abutment, thereby implanting the damaged permanent tooth of the patient into the artificial tooth.

Of course, in recent years, various types of implants having different shapes have been proposed in addition to the implants having the above-described configuration, but most of the fixtures have a screw shape having threads on the outer surface.

Therefore, when the implant is to be implanted into the alveolar bone of the injured area of the permanent tooth, the fixture is forcibly joined to the hole for mounting the fixture formed on the alveolar bone using the drill, And the fixture itself is screwed into the hole.

However, as described above, the fixture is forcedly engaged with the fixture mounting hole formed on the alveolar bone to implant the artificial tooth, and the artificial tooth using the implant is inserted while automatically forming the thread on the inner surface of the fixture mounting hole The direction of the repeated load during the food masting is directed to one point which is the lowest cross-section of the screw-type fixture, and its life span is relatively short as 5-10 years.

Further, in order to form or automatically form a thread on the inner surface of the fixture mounting hole, it is usually necessary to fix it at a depth of 8-13 mm so that the implantation is smoothly performed. In this process, the time taken for fusion of the damaged alveolar bone surface and the fixture becomes long, The risk of touching the mandibular nerve increases with the mandibular molar in the process of fixing the fixture to ensure a sufficient depth. In the case of the maxillary sinus lift, the sufficient depth can not be secured, and artificial bone graft is preceded There is a problem that the risk of sinus perforation increases with the procedure.
