Description

Implant Fixation Angle Correction Method and Implant Fixture Angle Corrector {Positonning device for dental implant}

The present invention is a kind of device for the initial fixation when implant fixture (fixture) (artificial tooth root), the implant fixture to maintain the initial fixation (fixture) by fixing to the peripheral alveolar bone (cortical bone insert) ( It relates to an angle correction method for fixing an artificial root and an angle correction device for fixing an implant fixture (artificial root).

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 the natural tooth does not cause tooth decay.

Such implants can be placed in the alveolar bone immediately depending on 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.

Such implant fixtures must undergo initial fixation at the time of treatment according to various factors of the patient, and bone fixation between fixture and alveolar bone should be achieved.

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.
