Implant Fixture Fixation Method and Implant Fixture Fixation Device {Positonning device for dental implant}

The present invention relates to an initial fixing method and apparatus of a dental implant fixture (artificial tooth root),

Form the cortical bone insert of the tooth to be treated, and implant the implant fixture in the center, and then fix the cortical bone fixture (2) on the edge of the cortical bone insert, the central through-hole is located in the central groove of the lower implant fixture An implant fixture fixing method and an implant fixture fixing device for fixing an implant fixture and a cortical bone fixture together with a cortical bone insert to a cover screw.

Implants are originally a substitute that recovers when human tissue is lost, but dental implants refer to implanting artificial teeth.

In order to replace the lost tooth root (root), a tooth root made of titanium and other materials that are not rejected by the human body is planted in the bone where the tooth falls out and the artificial tooth is fixed to restore the function of the tooth.

In the case of a general prosthesis or denture, the bone of the surrounding tooth is damaged over time, but the implant does not damage the surrounding dental tissue, but the same shape and function as natural teeth does not cause tooth decay.

Such implants can be placed in the alveolar bone immediately according to the patient's condition,

Implant fixtures have been implanted 3 to 6 months after bone graft using bone grafts if the implant fixture (artificial root) is impossible due to natural absorption and artificial loss of the alveolar bone.

Implant fixture should be fixed at the initial stage of treatment according to various factors of the patient.

If the initial fixation is not performed when the existing implant fixture is placed, the existing implant fixture is removed and a longer implant fixture or thicker implant fixture is re-planted or bone grafted. There was a disadvantage in that the procedure time is long, and there are many studies to solve these problems because there is a high risk of failure and side effects during the procedure.

If the initial fixation is not performed when the existing implant fixture (artificial root) is placed, remove the existing implant fixture and re-insert or implant a longer implant fixture or a thick implant fixture for a certain period of time. Discomfort and cost of the patient, there is a disadvantage that the procedure time is long, and also to reduce the risk of the procedure failure and side effects during the re-treatment is a problem to be solved by the present invention.

In order to solve the above object, the present invention is to form a cortical bone insertion portion of the tooth to be treated, planting the implant fixture in the center, and then fix the cortical bone fixture (2) to the border of the cortical bone insert, central tube It is an object of the present invention to provide an implant fixture fixing method and an implant fixture fixing device for fixing the implant fixture and the cortical bone fixture to the cortical bone inserting portion with the cover screw located in the center groove of the lower implant fixture. It is a solution.

According to the present invention, bone fixation between the fixture and the alveolar bone is achieved only by initial fixation during the procedure according to various factors of the patient, and when the initial fixation is not performed when the implant is fixed, the existing fixture is removed and the Longer implant fixtures or coarse implant fixtures were reinserted or implanted after a certain period of time to resolve the disadvantages of patient discomfort, cost, and procedure time, and the risk of failure and side effects during reoperation. Simultaneously with the effect of reducing high problems, the procedure is easy and its structure is simple, thereby reducing the procedure time and the pain of the patient and having the advantage of being economically saved.

In order to achieve the above object, the present invention forms a cortical bone inserting portion and becomes narrower toward the lower portion of the cortical carbon inserting portion, so that the end portion is pointed and inserts the fastener (1) having a male thread on the surface thereof. Is located in the upper part of the fixture (1) is fixed to the edge of the cortical bone inserting portion 2 and the cortical bone fixture of the cortical bone fixture 2 penetrates through the body central hole 21 of the fastener (1) The present invention relates to a method for fixing an implant fixture with a cover screw (3) inserted into and fixed to an upper central groove of the implant and an apparatus for fixing an implant fixture.

  The present invention is to form a cortical bone insertion of the tooth to be treated, planting the implant fixture in the center, and then fix the cortical bone fixture (2) on the border of the cortical bone insert, the central through the central implant of the lower implant fixture It is a method of fixing the implant fixture and the cortical bone fixture together with the cover screw from the upper portion to the cortical bone insert portion.
