Description

Fixture for implant operation < RTI ID = 0.0 >

The present invention relates to a double helical implant fixture, and more particularly, to a novel double helical implant fixture which is fastly inserted into an alveolar bone during implantation and has excellent bonding strength to the alveolar bone.

Implant procedures performed in the dentistry consist of implanting a fixture to replace the root of the alveolar bone, and combining the artificial teeth with the fixture.

This implant procedure is described in detail. When the fixture is screwed to the alveolar bone, the gums are sutured. When the bone is fused around the fixture 3 to 6 months later, the gingival incision is made and the healing abutment is fixed to the fixture Combine to allow the gum to heal, then remove the healing abutment and connect the artificial tooth (prosthesis) to the fixture.

Since the artificial teeth are bonded to the alveolar bone by the fixture, the binding force between the fixture and the alveolar bone is very important. If the fixture and the alveolar bone are loosened, the artificial teeth are shaken and the teeth can not function properly.

On the other hand, in order to increase the coupling force between the fixture and the alveolar bone, it is necessary to form the threaded bone forming the thread of the fixture deeply so as to project a relatively large amount of thread. However, if the screw thread of the fixture protrudes as much as this, a lot of force is required to screw the fixture to the alveolar bone, and since it takes a long time to fasten the fixture to the alveolar bone, the implantation procedure time becomes long, .

Korean Utility Model Registration No. 20-0456292 (October 17, 2011)

The present invention has been proposed in view of the above points, and the present invention has been made in view of the fact that since the implant is rapidly implanted into the alveolar bone during implantation, the implantation time is shortened and the bonding force with the alveolar bone is also excellent, And to provide a double helix implant fixture of a new configuration.

According to one feature of the present invention, in a fixture that is coupled to a patient's alveolar bone at the time of implant treatment, a first threaded bone 122 is formed on an outer circumferential surface, and a first threaded tooth 112 is formed by the first threaded bone 122 And a head part (200) formed on an upper end of the stem part (100) and coupled with an abutment and a prosthesis, wherein an outer end of the first thread part (112) The second threaded bore 124 having a relatively shallower depth than the threaded bore 122 is formed in parallel with the first threaded bore 122 so that the outer end of the first threaded bore 112 is connected to the second threaded bore 124 The upper surface of the first thread 112 and the upper surface of the second thread 114 are inclined downward toward the outer side and the upper surface of the first thread 112 is inclined downward. And the lower surface of the second screw thread 114 are formed by the lower inclined surface 109 inclined downward toward the outer side The double spiral implant fixture as claimed is provided for.

According to another feature of the present invention, the first threaded bones 122 are formed to be two to three times deeper than the depth of the second threaded bones 124.

In the present invention having the above-described configuration, the first and second threaded bores 122 and 124 having different depths are formed, and the first and second threaded bores 122 and 124, (112, 114) are formed.

The present invention is excellent in the fastening force with the alveolar bone because the alveolar bone is firmly screwed to the alveolar bone by the first thread 112 formed by the relatively deep first thread 122. Therefore, the present invention has no fear of being separated from the alveolar bone, so if the implant is used with the present invention, it is possible to perform robust and stable procedures.

Particularly, since the pitch of the first thread 112 formed by the relatively deep first thread 122 is longer than that of the second thread 114, the fastener is fastened to the alveolar bone, The procedure time is shortened, and it can give satisfaction to the patient and the patient.
Since the upper and lower surfaces of the first and second threads 112 and 114 are composed of the upper inclined surface 108 and the lower inclined surface 109 that are inclined downward as they go outward, the first and second screw threads 112 and 114, Since the bottom surface of the first and second threads 112 and 114 is formed by the lower inclined surface 109, the first and second threads 112 and 114 are used to fix the alveolar bone to the alveolar bone, The effect of being pulled toward the stem portion 100 is obtained, thereby further improving the bonding force between the present invention and the alveolar bone.

1 is a partial cutaway front view showing a first embodiment of the present invention;
2 is a partial cutaway front view showing a second embodiment of the present invention;

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a partial cutaway front view showing a first embodiment of the present invention. The present invention relates to a fixture for implanting into an alveolar bone for implantation, comprising: a stem portion 100 having a threaded portion formed on an outer circumferential surface thereof and screwed to a patient's alveolar bone; And a head part 200 on which an abutment and a prosthesis are coupled.

The head part 200 is formed with a coupling groove 210 to which the abutment and the prosthesis are coupled. The structure of the head part 200 is the same as that of the head part of the conventional fixture.

The threaded portion formed in the stem portion 100 includes a first threaded portion 122 and a second threaded portion 124 having a relatively shallower depth than the first threaded portion 122, 122 and 124 form first and second threads 112 and 114, respectively.
The first threaded bones 122 are formed in the stem portion 100 to have a predetermined pitch, and the first threads 112 are formed by the first threaded bones 122.
The second threaded boss 124 is formed at an outer end of the first threaded portion 112 so as to have a shallower depth than the first threaded boss 122 in parallel with the first threaded boss 122 . As the second threaded bore 124 is formed in the first thread 112, the outer end of the first thread 112 is vertically branched by the second threaded bore 124, A second thread 114 protruding from the second threaded bore 124 is formed at the outer end of the second threaded bore 124. That is, the first screw thread 112 is formed with two second threads 114 on the second thread thread 124 and on the lower side thereof.
The reference numeral 130 is a cutting surface formed at the lower end of the outer circumferential surface of the stem portion 100 to cut the alveolar bone when the present invention is implanted in the alveolar bone so that the alveolar bone can be easily implanted. Since the cutting surface 130 is a typical configuration, a detailed description thereof will be omitted.
When the present invention having such a constitution is screwed into the alveolar bone at the time of the implant procedure, the first thread 112 is deeply embedded in the alveolar bone to improve the fastening force with the alveolar bone, and thus the present invention is not likely to be loosened at the alveolar bone.

The present invention also contemplates that the pitch of the first threads 112 is greater than the pitch of the second threads 114 because the outer ends of the first threads 112 are split by the second threads 124 to form the second threads 114. [ 114). Since the pitch of the first screw thread 112 formed by the first screw thread 122 having a relatively deep depth and deeply inserted into the alveolar bone is long, the present invention is relatively fastened to the alveolar bone. Therefore, the implant procedure time is shortened.
Preferably, the depth of the first threaded bones 122 is two or three times deeper than the depth of the second threaded bones 124. If the depth of the first threaded bone 122 is not twice as deep as the depth of the second threaded bone 124, the degree of improvement of the fastening force between the first threaded tooth 112 and the alveolar bone is insignificant. If the depth of the first threaded bore 122 is deeper than three times the depth of the second threaded bore 122, the strength of the stem portion 100 becomes weak and the stem portion 100 may be damaged.

Hereinafter, other embodiments of the present invention will be described, and the same configurations and effects as those of the above-described embodiments will not be described.

2 is a partial cutaway front view showing a second embodiment of the present invention. The top surface of the first screw thread 112 and the second thread screw 114 are sloped downward toward the outer side, that is, the upper slope 108 inclined toward the lower end of the stem 100, as shown in FIG. And the bottom surfaces of the first screw thread 112 and the second screw thread 114 are formed as a lower side slope 109 inclined downward toward the outside.
The upper surface of the second thread 114 located on the upper side of the second threaded boss 124 is the same as the upper surface of the first thread 112 and the lower side of the second threaded boss 124 The bottom surface of the second thread 114 located on the same side as the bottom surface of the first thread 114.

Since the upper and lower surfaces of the first and second screw threads 112 and 114 are formed by the upper inclined surface 108 and the lower inclined surface 109 inclined downward toward the outer side in this manner, And has a shape inclined downward toward the end.
In particular, when the lower surface of the first and second screw threads 112 and 114 is formed as the lower inclined surface 109, the first and second screw threads 112 and 114 are inserted into the first and second screw threads 112 and 114, respectively, Since the lower inclined face 109 which is the bottom face of the first and second thread 112 and 114 penetrates from the upper side to the lower side of the alveolar bone, the first and second threaded portions 112 and 114 have an effect of pulling the alveolar bone toward the stem portion 100 .

Therefore, the present invention and the alveolar bone bonding force are improved, and the present invention is more firmly bonded to the alveolar bone.
