Description

        Implant fixture with bone cutting knife

The present invention relates to a dental implant fixture that is implanted by expanding the bone width when the width of the alveolar bone can not be accommodated because the width of the alveolar bone is narrow when the fixture is placed, the diameter of the natural tooth that becomes smaller from the upper end to the lower end The present invention relates to a fastener body and a pressure-insertable dental implant fixture having one or more fractured cutting blades installed from top to bottom on an outer surface of the fastener body.

In general, an implant is a replacement that is originally restored when human tissue is lost, but in the dentist, an implant of artificial teeth is implanted. To replace the lost tooth roots (roots), the roots made of titanium (titanium), etc., which are not rejected by the human body, are planted in the alveolar bone where the teeth fall out, and the artificial teeth are fixed to restore the function of the teeth.

In general, since the end of the symmetrical shape is provided with a screw thread and fixed by screwing into the alveolar bone, an expensive device is needed to spray water or remove dregs in order to heat or cool the alveolar bone remaining portion. ,

In the case of the conventional simple pressure-type implants, pressing on the alveolar bone was possible, but since pressure-setting on the alveolar bone is difficult to fix, recently, pressure-type implants have been rarely used.

In particular, when the bone width of the alveolar bone is small, the conventional implanted implant procedure was almost impossible.

[0003] Patent Publication No. 20-327089 relates to an implant invented from the viewpoint of a biological electromagnetic field, in contrast to the improvement of a dental implant from an existing mechanical viewpoint, and relates to an implant to which a biological magnet is added. The present invention describes a technique for assisting the regeneration of the living tissue of the implant and improve the binding of the living tissue and the implant,

In Publication No. 20-362463, the body of the fixture consists of vertical and multiple inclined sections, and adopts a multi-threaded structure such as two rows of threads, so that the stress concentrated in the CORTICAL BONE is changed to CANCELLOUS BONE. By dispersing, it can reduce bone loss and secure high initial fixation force and high fixation force at final settling even in weak bone quality.Low roughness can be obtained by precisely machining the predetermined height of the color of the body in consideration of biological width (BIOLOGICAL WIDTH). By implementing the mechanical surface, the affinity with the gingival can be secured during bone loss.The tip of the torso has a dome shape so that it can be buried easily by pushing the bone even in the case of weak bones. Self tapping is possible, and the fusion is improved by blasting the surface of the body to increase the surface area. It can be seen that is disclosed.

Conventional dental implant fixtures as described above require the formation of fixture fixtures of fixture size in the implantable alveolar bone,

If the bone width of the alveolar bone is narrow, it is impossible to form a fixture, so the bone graft surgery should be performed first to make enough bone width, and then the fixture fixation should be performed again. Therefore, the healing period increases and the cost of bone transplantation increases. It is a task to solve the problem.

The present invention, in order to solve the above problems, the fixture body of the form of natural tooth gradually increasing in diameter from the bottom to the top shows the effect of pushing the bone to the outside during the installation, at this time one or more fractures formed on the outside of the fixture body It is a problem solving means of the present invention to provide a pressure-insertable dental implant fixture having a fractured cutting blade formed so that the forearm can be easily expanded and placed by cutting the bone.

In the present invention, when the alveolar bone width is narrow and it is difficult to implant the implant fixture, it is possible to form a minimal fixture fixture on the alveolar bone and press-fit it.

At this time, since the implantation sphere is expanded while the bone is made in the longitudinal direction of the alveolar bone, the healing period is shorter, more economical, and the ease of the procedure is increased compared to the conventional method of implanting after bone transplantation.

In order to achieve the above object, the present invention relates to a pressure implantable dental implant fixture formed fracture fracture.

The present invention is a device for performing an implant procedure to facilitate the bone width expansion by increasing the diameter of the fixture body by inverting the alveolar bone in the longitudinal direction when the pressure-insertable dental implant fixture is formed in the bone cutting blade.

According to the present invention, the bone width is expanded while the fixture is placed by pressure, so when the alveolar bone width is narrow and it is difficult to implant the implant fixture, the implant can be pressurized with only minimal formation of the implant. Therefore, there is no need for a separate bone enlargement mechanism or material. It is a pressure implantable dental implant fixture formed fracture fracture.

The present invention is a fixture body (1), the abutment insert (2) installed in the upper center of the fixture body (1), and one or more fracture cutting blades installed from the top to the bottom (vertically) on the outside of the fixture body (1) 3), the fixture body (1) is a tooth shape of a natural tooth that is smaller in diameter from the top to the bottom,
