Abstract
Description
The present invention relates to a dental implant that fixes a prosthesis to an abdomen using frictional force of a fastening pin, and more particularly to a dental implant having a fastening pin having a structure (for example, a microprojection or the like) The protrusions are pressed on the inner surface of the second engaging hole during the insertion and the frictional force is greatly increased, and the frictional force is applied to the prosthesis and the abutment and fixed to the second engaging hole through the first engaging hole of the prosthesis. The present invention relates to an improved dental implant that can greatly reduce the manufacturing cost of the fastening pin and can easily and easily perform the implant treatment without breakage during the procedure.
Generally, an implant implies a substitute of a lost natural tooth, or a fixture is implanted in the jawbone for a predetermined period of time to be fused with the jawbone, and then a prosthesis such as a fastening member and an artificial tooth is fixed thereon. It is a dental procedure that restores function.
In general prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants do not injure the surrounding dental tissue, and they have the same function and shape as the natural teeth, but do not have cavities. Therefore, they can be used semi-permanently.
Implants also improve the function of dentures in patients with single missing teeth restoration, as well as partial and total toothless teeth, and improve the aesthetic aspects of dental prosthesis restoration. Furthermore, it helps to stabilize the dentition as well as to disperse the excessive stress applied to the surrounding supporting bone tissue.
In the case of such an implant, a fixture that is implanted in the jawbone and a fastening portion of the abutment are coupled to an upper shaft hole of the fixture, and a prosthesis is fixed to the upper portion of the abutment.
Such an implant has a resilient coupling structure in which the fixture and the abutment have a screw-type connection structure or the fixture connection groove and the abutment connection protrusion are complementarily coupled to each other.
In such an implant procedure, a method of attaching an artificial tooth prosthesis to an abdomen is a method of bonding a prosthesis to an abutment using a dental cement.
However, when bonding the prosthesis to the abutment using conventional dental cement, if the prosthesis, fixture, abutment, or the like should be repaired or the prosthesis should be separated for treatment or the like, there is a problem.
In addition, in order to solve the above-described problem, a weak adhesive is used in order to smoothly separate the prosthesis from the abutment. In such a case, however, sudden prosthesis escapes from the abdomen to make the patient embarrassed, There was also a problem that occurred.
In order to solve such a problem, Korean Patent Registration No. 10-1160121 entitled "Dental Implant" describes a fixture that is placed at a predetermined depth in an alveolar bone to form an artificial root and an external appearance of an artificial tooth, An abutment having one end coupled to the coupling groove of the prosthesis and the other end engaged with the fixture and a coupling means coupling the prosthesis to the abutment do.
The coupling means may include a first coupling hole formed at one side of the coupling groove of the prosthesis, a second coupling hole formed concentrically with the first coupling hole at an outer circumferential surface of the abutment, And a coupling pin inserted into the coupling hole to connect the prosthesis with the abutment, wherein a housing supporting the outer circumferential surface of the coupling pin is coupled to the first coupling hole of the prosthesis, 1 shows a structure of a dental implant in which at least one planar portion is formed on each coupling surface of the first coupling hole and the housing so as to prevent rotation of the housing in the coupling hole.
However, such a conventional technique is complicated in the structure of the coupling means for joining the prosthesis and the abutment, and it is necessary to fasten the crown and the abutment using a screw having little error tolerance. Therefore, If the prosthesis, abutment screw, and coupling screw are not joined with each other by 100% perfect surface contact, when the occlusal force is applied to the prosthesis after the fastening, the screw may be deformed, May be loosened or fracture may occur due to sustained occlusal forces. In addition, since the screw is rotated to the side of the prosthesis in the narrow mouth to be fastened and dismantled, fastening and disassembly are not easy and may not be possible in some cases.
In order to solve such a conventional problem, the applicant of the present invention has solved such a conventional problem through the "dental implant" of Korean Patent No. 10-1361236.
The prior art of the applicant of the present invention can easily and easily perform the implant procedure for coupling the prosthesis to the abutment as the one-touch coupling method of the fastening pin, and it is possible to safely secure the joint state between the abutment and the prosthesis after the procedure And has an excellent and excellent effect of easily separating the prosthesis even in the case of repairing the prosthesis or abutment, or in case of separating the prosthesis for treatment or the like.
However, such prior art has encountered some technical problems during actual practice.
That is, since such fastening pins of the prior art are manufactured using a metal material, they must be manufactured using a high-priced shape memory alloy which is harmless to the human body, for example, nickel-titanium or the like, It is difficult to firmly construct the structure of the fastening pin itself, so that the fastening pin is broken, and thus, difficulties arise in the production of the fastening pin. In addition, since the fastening fins are fasteners using the elastic force of metal, elastic fastening can be performed only when the length is a predetermined length. Particularly, since the diameter of the abutment used in the lower incisor is small in bucco- There are technical limitations and problems in using the fastener of the technology.
Accordingly, the applicant of the present invention has made efforts to solve this problem through the material and structural improvement of the fastening pin in order to solve the problem of the prior art, and has come to develop the present invention.
It is an object of the present invention to solve the conventional problems as described above, and it is an object of the present invention to greatly reduce the manufacturing cost of a fastening pin for fixing a prosthesis to an abdomen, The present invention provides an improved dental implant that can easily and easily perform an implant procedure by allowing the abutment and the prosthesis to be joined or separated easily.
It is a further object of the present invention to provide a method and apparatus for disposing a fastening pin for disposable use after use and easily replacing it with a new fastening pin and using one type of fixture to fix the abutment and prosthesis universally in various implant procedures The present invention provides an improved dental implant for facilitating the implant procedure.
According to an aspect of the present invention, there is provided a method of manufacturing an artificial tooth, comprising the steps of: preparing a fixture that is placed on an alveolar bone to form an artificial root, a lower abutment coupled to the fixture and an upper abutment coupled to the prosthesis, The dental implant according to claim 1,

And the fastening pin is made of a non-metallic synthetic resin that is frictionally fastened to the second engagement hole when the fastening pin passes through the first engagement hole of the prosthesis and is fitted into the second engagement hole of the abutment.
Preferably, the fastening pin may have a metallic structure formed therein.
More preferably, the fastening pin has a plurality of fine protrusions formed on its outer surface so that the fine protrusions are compressed and deformed when inserting into the first and second fastening holes, thereby providing frictional force.
Most preferably, the diameter of the fastening fin is smaller than or equal to the inner diameter of the first and second engagement holes, and the outer diameter of the microprojection is larger than the inner diameters of the first and second engagement holes, When the first and second engagement holes are inserted into the first and second engagement holes, the microprotrusions are entirely compressed and deformed around the body to be interference fit.
Preferably, the fastening fins are formed of any one of a rectangular, triangular, hemispherical, and trapezoidal shape of the fine protrusions, and a hollow space in which fine protrusions can be positioned at the time of shape deformation of the fine protrusions, Respectively.
