Description

Dental Implants {Dental Implant}

The present invention relates to a dental implant, and more particularly to the lower outer peripheral surface with respect to the abutment inserted into the fixture (embedded in the alveolar bone) and the crown fixed to the upper Due to the fastening member provided with a fastening member corresponding to the threaded portion, the threaded portion is formed on the abutment, so that the abutment can be installed on the fixture by directly pressing the outer circumferential surface of the abutment. The present invention relates to a dental implant for implantation.

In general, a dental implant is used to increase the volume of the dental implant so that it can be sufficiently wrapped through additional surgery, such as bone graft and bone elongation, in the jawbone at the site of the tooth defect or at the tooth extraction site. It is a dental treatment that restores the function of natural teeth by planting a biocompatible implant body on the stretched jawbone.

Dental implantation was practiced in ancient times, and artificial teeth made of gold and ivory were used in the 16th and 17th centuries.In the early 20th century, metal implants made of gold, silver, lead, iridium, iron, and cobalt alloys were used. Developed.

Subperiosteal and titanium blade implants have been developed and popularized since the 1940s, but have short life spans and low success rates. Later, in 1982, after a 15-year study of osteoadhesive implants by Branemark, Sweden, in Toronto, Canada, the success rate exceeded 90% and became popular worldwide.

Such an implant (implant) is originally meant to replace the restoration when the tissue of the human body is lost, but in the dentist refers to artificial tooth transplantation.

In other words, the implant is implanted into the alveolar bone from which natural teeth have been removed and affixed to the alveolar bone from which natural teeth have been removed. It is a cutting-edge procedure to fix the teeth to restore the original function of natural teeth.

The dental implant consists of a fixture placed in the alveolar bone, an abutment fastened to the fixture, and a crown of an actual tooth shape mounted on the abutment.

Here, the fixture (fixture) corresponding to the root is also known in the art as an artificial tooth, a carcass or a fixture, the abutment is also called abutment or abutment, the crown corresponding to the tooth is an artificial tooth, Crown, also called prosthesis.

In addition, the prior art of dental implants having a variety of types and methods of treatment, 'tooth implant system' of the Republic of Korea Patent Office Patent No. 10-0419738 and 'Healing' of the Republic of Korea Patent Publication No. 10-0677870 Abutments and dental implants having the same, and 'implants for flapless surgery or mini-flap surgery' of the Republic of Korea Patent Publication No. 10-0879777 has been disclosed.

In other words, in general, artificial teeth refers to teeth made artificially so that a person without teeth can eat food. These artificial teeth are divided into dentures that can be inserted into and removed from the gums, and artificial teeth permanently fixed to the gums.

In order to permanently fix the artificial tooth to the alveolar bone of the gum, an implant is used, which is an artificial tooth which penetrates the alveolar bone directly through the soft tissue of the gum and is screwed into the upper inside of the artificial root. It consists of an abutment where artificial teeth are fixed.

Therefore, in order to fix the artificial tooth to the patient, first, the artificial tooth penetrates the soft tissue of the gum and screw firmly to the alveolar bone. Then screw the abutment firmly on top of the artificial root fixed to the alveolar bone. And finally, the artificial teeth fixed to the patient are fixed to the abutment bonded to the artificial roots.

Then, the artificial teeth will be semi-permanently implanted by the implant consisting of artificial tooth roots and abutment portion, thereby serving as a natural tooth.

Here, each patient undergoing an implant for artificial teeth has different characteristics such as alveolar bone shape and natural tooth angle. Therefore, when manufacturing the implant part of the implant, the patient's alveolar bone shape and natural tooth angle are carefully examined in advance through radiography and computed tomography.

This is because the artificial teeth are coupled to the upper portion of the zone and the artificial root is coupled to the lower portion of the zone, so the angle between the alveolar bone and the artificial teeth is determined by the angle between the upper and lower portions of the support.

However, even if the angle between the upper part and the lower part is made to meet the condition such as the alveolar bone shape and the natural tooth angle through careful examination of the abutment in advance, the artificial root is the alveolar bone due to other external factors during the procedure. There was a problem that can not be modified if not sold at a predetermined position and angle.

That is, since the angle between the upper part and the lower part of the abutment part is determined, it is impossible to change it. Therefore, the only way was to remake the abutment to compensate for the distorted angle of the artificial root.

In addition, the angle between the upper portion and the lower portion of the zone is configured differently for each patient, so there was also a problem in that it is impossible to mass-produce and costly to produce.

Because of these problems, the present inventor has proposed a 'dental implant capable of adjusting the angle of the abutment' as shown in FIG. 1, the Korean Patent Office Publication No. 10-1065924.

It is composed of a fixing bolt 50 for fixing the rotating body 40 so that the circular ball 31 is strongly pressed from the ball groove 42.

However, the patent technology is that the angle adjusting means are screwed to the bolt hole 43 and the screw hole 44 formed on one side and the other side of the rotating body 40, respectively, but strongly pressed into the fixing bolt 50, but the circular ball 31 There is a problem in that the circular ball 31 is not sufficiently pressed over time because it is not directly compressed on both sides and indirectly compressed.

The present invention has been made to solve the above problems, the lower part is inserted into a fixture embedded in the alveolar bone (thread) in the upper portion of the abutment (abutment) to the crown is fixed to the lower outer periphery (abutment) Due to the fastening member having a fastening portion corresponding to the threaded portion, the outer periphery of the abutment can be directly pressed to install the abutment on the fixture, so that the bonding force is improved than before. The purpose is to provide a dental implant that can be.
