Description
The present invention relates to a dental implant, and more particularly to an abutment which is inserted into a fixture immersed in an alveolar bone in the lower part and abutment to which a crown is fixed in an upper part, Since the screw portion is formed on the peripheral edge and the fastening member having the fastening portion corresponding to the screw portion is directly pressed on the outer peripheral edge of the abutment to mount the abutment on the fixture, And more particularly to a dental implant for precisely performing an implant treatment.
Generally, dental implants are used to provide a volume that can be adequately wrapped through additional operations such as bone grafting and bone chest surgery on the site of a tooth defect or on the jawbone of a tooth extraction site It is a dental treatment that restores the function of the natural teeth by implanting a biocompatible implant body on the enlarged jawbone.
In the early 20th century, metal implants made of gold, silver, lead, iridium, iron, and cobalt alloys were used in the early 16th to 17th centuries. Developed.
Since the 1940s, suborbital implants and titanium blade implants have been developed and popularized but have a short life span and a low success rate. Since 1982, Branemark, Sweden, in Toronto, Canada, has published bone anchoring implants for 15 years, with a success rate of more than 90%.
Such an implant implies a substitute that restores when the tissue of the human body is lost, but refers to an artificial tooth implant in a dentist.
That is, an implant is made by implanting an artificial root fixture made of titanium, which does not have a rejection reaction to the human body, on an alveolar bone that has been extracted from a natural tooth, so as to replace the root of the lost natural tooth, It is a cutting-edge procedure that restores the original function of a natural tooth by fixing a crown.
The dental implant is composed of a fixture to be placed on the alveolar bone, an abutment to be fastened to the fixture, and a crown of a real tooth shape to be mounted on the abutment.
Here, a fixture corresponding to a root is referred to as an artificial root, a tooth or a fixture in the art, an abutment is also referred to as abutment or abutment, and a crown corresponding to a tooth is an artificial tooth, Also called crown, prosthesis.
The prior art of dental implants having various types and procedures is disclosed in Korean Patent Application Publication No. 10-0419738 entitled " Dental Implant System " and Korean Patent Application Publication No. 10-0677870 Abutment and dental implant with the abutment, "and" implant for flapless operation or mini-flap operation "of Korean Patent Registration No. 10-0879777.
In other words, artificial teeth are generally made artificially so that a person who does not have an artificial tooth can eat food. These artificial teeth are divided into dentures that can be inserted and removed from the gums and artificial teeth that are permanently fixed to the gums.
An implant is used to permanently fix the above artificial teeth to the alveolar bone of the gum. This implant includes an artificial tooth that penetrates the soft tissue of the gum and is directly inserted into the alveolar bone, And an abutment on which an artificial tooth is fixed.
Therefore, to fix the artificial teeth to the patient, the artificial root is inserted through the soft tissues of the gums and screwed securely to the alveolar bone. Then, the abutment portion is fixed to the upper part of the artificial root fixed to the alveolar bone by screwing. Finally, fix the artificial teeth that are made to the patient in the zone where they are attached to the artificial root.
Then, the artificial tooth is semi-permanently implanted by the implant made up of the artificial root and the abutment portion, so that it can serve as a natural tooth.
Here, there are different characteristics of the alveolar bone shape and the natural angle angle for each patient who performs the implant for the artificial tooth. Therefore, when fabricating the abutment area of the implant, the shape of the alveolar bone and the angle of the natural angle of the patient are thoroughly inspected in advance through radiography and computed tomography.
This is because an artificial tooth is coupled to the upper part of the abutment part and an artificial tooth is coupled to the lower part of the abutment part, so that the angle between the alveolar bone and the artificial tooth is determined by the angle formed by the upper part and the lower part of the support part.
However, even if the angle between the upper part and the lower part of the abutment part is carefully inspected beforehand in accordance with the condition of the alveolar bone and natural angle of the patient as described above, It is not possible to correct it unless it is immersed in a predetermined position and angle.
That is, since the angle between the upper and lower portions of the zone is fixed, it is impossible to change the angle. Therefore, there was no way to rebuild the abutment to compensate for the angled angle of the artificial root.
Also, since the angle formed between the upper and lower portions of the land portion is different for each patient, mass production is also impossible and the manufacturing cost is also increased.
As a result, the inventor of the present invention has proposed a dental implant capable of adjusting the angle of a land portion of Korean Patent Registration No. 10-1065924, as shown in FIG.
That is, in the patented technology, the angle adjusting means comprises a
However, in the above-described technology, the angle adjusting means is screwed to the
SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide an abutment which is inserted into a fixture immobilized on an alveolar bone, And the fastening member having the fastening portion corresponding to the threaded portion can directly press the outer circumference of the abutment to install the abutment on the fixture. Therefore, the fastening force is improved more than the conventional one, And to provide a dental implant capable of performing a dental implant.
In order to achieve the above object, a dental implant according to an embodiment of the present invention includes a fixture to be inserted into an alveolar bone, a fixture to be inserted into an upper portion of the fixture and a crown to be fixed to an upper portion thereof, Wherein the abutment comprises a connecting member having a spherical spherical upper portion and a lower portion fixed to the fixture, a cut portion having one side opened and one side opened, And a threaded portion formed along an outer circumference at a lower outer side of the ball groove portion to which the spherical ball is inserted while expanding the incision portion, and a truncated conical-shaped rotary member having the connecting member and the rotary member coupled thereto, And a fastening member having a fastening portion formed inside thereof.
In addition, since the threaded portion and the fastening portion are screwed to rotate the fastening member located outside the lower portion of the rotary member, the spherical ball is pressed and fixed directly from the ball groove portion while the interval between the cutoff portions is reduced.
Further, the tightening member may be a hexagonal nut having a fastening portion formed on the inner side thereof.
In addition, the connecting member may be tapered so as to be tapered downward, and correspondingly, an upper inner side of the fixture may be formed into a tapered and narrowed insertion groove so as to be pressed into the insertion groove.
According to the present invention, it is possible to freely adjust the angle between the fixture and the crown to fit the patient, while the fastening member having the inside fastening portion directly presses the screw portion, so that the fastening force is stronger than that of the prior art, .
Further, after the implant treatment, it can be maintained over a longer period of time than before, and there is an advantage that the economic burden on the patient can be reduced.
In addition, there is an advantage that a more effective structure and a mass production can be achieved for each part while having a simpler structure than the conventional one, and a ripple effect can be expected in dental procedures.
