Description

Dental Implant Fixtures {DENTAL IMPLANT FIXTURE}

The present invention relates to a fixture of a dental implant, and more particularly, to a fixture of a dental implant that can provide excellent initial fixation force while minimizing bone stress by shortening the implantation time. .

Implant refers to a replacement that restores when the original tissue is lost, but in dentists it refers to a series of procedures for implanting an artificial tooth.

To replace the lost roots (roots), a fixture made of titanium, etc., which is not rejected by the human body, is planted in the alveolar bone where the teeth fall out, and the artificial teeth are fixed to restore the function of the teeth. It is a procedure to make.

In the case of general prosthetics or dentures, the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they have the same function or shape as natural teeth and do not cause tooth decay.

Artificial tooth procedures (also called implants or implant procedures) vary depending on the type of fixture, but use a drill to drill the implantation position, then implant the fixture into the alveolar bone and fusion to the bone, then abutment the fixture After joining the abutments, it is usually done by putting the final prosthesis on the abutment.

Implants improve the function of dentures, improve the aesthetic aspects of dental prosthetic restorations, as well as dissipate excessive stress on surrounding supportive tissue, as well as single missing restorations. It also helps stabilize the teeth.

Such implants generally include fixtures that are placed as artificial roots, abutments that are coupled to the fixture, abutment screws that secure the abutments to the fixture, and artificial joints that are coupled to the abutments. Includes teeth. Here, a healing abutment (not shown) is coupled to the fixture to maintain the engaged state before the abutment is coupled to the fixture, that is, during the period until the fixture is fusion-bonded to the alveolar bone.

A fixture, which is a component of the implant, serves as an artificial root as a part that is placed in a drill hole formed in the alveolar bone by using a drill or the like at a position where the implant is to be treated. Therefore, the fixture must be firmly placed in the alveolar bone.

Thus, a screw portion (threaded thread) is formed on the outer surface of the fixture so as to be firmly coupled to the inner wall portion of the alveolar bone forming the drill hole.

These screws are inserted into the alveolar bone to allow the fixture and the alveolar bone to be firmly coupled, and to increase the contact area between the fixture and the alveolar bone, thereby reinforcing the fixation force of the fixture to the alveolar bone, in particular, the initial stability. do.

Therefore, the shape of the screw portion formed in the fixture of the implant may be an important factor.

In fact, focusing on the initial tightening force to form a tighter thread on the outer surface of the fixture, for example, a narrow pitch interval, the initial clamping force can be strengthened, but the placement time is inevitably delayed, thus increasing the bone stress. Can be. On the contrary, by focusing on shortening the implantation time, for example, forming a screw part having a wide pitch interval on the outer surface of the fixture, the implantation time can be shortened, but the initial fixing force is likely to be weak. Therefore, the development of a structure that can provide a good initial fixing force while minimizing the stress by reducing the implantation time is required.

Therefore, the technical problem to be achieved by the present invention is to provide a fixture of a dental implant that can provide excellent initial fixation force while minimizing bone stress by reducing the implantation time.

According to an aspect of the invention, the body portion is formed with a collar (collar) of a predetermined length in the upper end region; And a screw portion spirally formed on an outer surface of the body portion, wherein the screw portion includes: a wide screw portion formed along a longitudinal direction of the body portion from an implantation end; And a narrow screw portion formed from the point where the wide screw portion ends to the collar region of the body portion, the narrow screw portion being narrower than the width of the pitch interval of the wide screw portion.

The lowermost narrow screw portion of the wider screw portion may be partially overlapped with the uppermost wide screw portion of the wider screw portion.

The wide screw portion may be a square screw, the narrow screw portion may be a triangular screw.

The angles of inclination with respect to the upper surface and the lower surface of the wide screw portion that are separated from each other based on the vertical surface of the distal end portion may be different from each other.

The pitch spacing between the wide screw portions may be 1.5 to 2.5 times the pitch spacing between the narrow screw portions.

The depth from the distal end of the screw portion to the outer surface of the body portion may be gradually increased toward the insertion end of the body portion.

The virtual outer line connecting the ends of the mountains of the screw portion, the first tapered section is provided to be gradually extended from the insertion end of the body portion toward the collar region of the body portion; A vertical section provided vertically along the longitudinal direction of the body portion at the point where the first tapered section ends; And a second taper section provided to gradually expand toward the collar region of the body portion at the point where the vertical section ends.

The length of the collar may be 1.0 mm to 1.5 mm.

The color region may be anodized.

It may further comprise a bevel portion formed in the upper corner region of the collar.

The apparatus may further include a twist cutting edge portion formed in the wide screw portion along the circumferential direction of the body portion.

The abutment may further include an abutment coupling portion provided in an inner region of the upper end of the body portion so that the abutment is coupled thereto.

The abutment coupling portion, the first depression in the primary portion along the longitudinal direction of the body portion from the upper end of the body portion; A secondary depression formed at a lower end of the primary depression in a second depression deeper in the longitudinal direction of the body portion; And a screw groove formed along a longitudinal direction of the body portion in the central region of the secondary recessed portion to which an abutment screw for fastening the abutment is fastened.

The secondary depressions may be formed in a wave shape along the circumferential direction.

The inner wall of the primary depression may form a tapered taper wall so that the diameter gradually narrows from the upper end to the lower end for strong bonding or tight bonding of the abutment.

According to the present invention, it is possible to shorten the implantation time to provide an excellent initial fixing force while minimizing the bone stress.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

1 is a perspective view schematically showing a process of implantation of the fixture of the dental implant according to an embodiment of the present invention.

As shown in FIG. 1, a large number of teeth 12 are arranged in the gum 11. Teeth 12 are primary digestive means for crushing food and sending them to the stomach, but may vary from person to person, but usually have about 28.

If any one of these teeth 12 is lost (when the posterior part is missing), the lost tooth 12 is not only aesthetically deteriorate but also inevitably considerably uncomfortable to chew food.

Thus, the fixture 100 is implanted as a means to replace the root 12a of the tooth 12 on the gum 11 of the lost tooth 12. Although not shown in detail in FIG. 1, the fixture 100 is implanted in the alveolar bone in the gum 11, which is preceded by a drill operation for implantation of the fixture 100 before implantation. That is, the drill hole (H) is processed at a predetermined position of the alveolar bone.

The fixture 100 may be made of titanium (Ti, Titanium) or titanium (Ti) alloy is not rejected to the human body.

Meanwhile, as described above, even in the related art, a fixture (not shown) is implanted as a means for replacing the root 12a of the tooth 12 in the alveolar bone of the gum 11 where the tooth 12 is lost. Has come.

However, conventional dental implant fixtures (not shown) have not only a simple straight screw shape, but also a screw structure formed on the outer surface of the body part, which has a uniform simple structure. There is a need for the development of an improved structure fixture 100 that can provide excellent initial fixation force while minimizing bone stress by reducing time. Accordingly, the present invention proposes a fixture 100 having an improved structure according to this need.

For reference, the fixture 100 of the present embodiment, which will be described below, may be used when the first implant is performed or directly placed on the corresponding alveolar bone without replenishing a predetermined bone replacement material at the damaged part when the procedure is failed. It may be used for emergency purposes.

FIG. 2 is a perspective view of the fixture of the dental implant shown in FIG. 1, FIG. 3 is a view of a state in which a screw part is removed from FIG. 2, FIG. 4 is a cross-sectional structural view of FIG. 2, and FIG. 5 is FIG. 2. 6 (a) and 6 (b) are enlarged structural views of regions X and Y of FIG. 4, respectively, FIG. 7 is a perspective view of abutment, and FIG. 8 is a dental according to an embodiment of the present invention. It is an example of the surgical implant fixture.

Referring to these drawings, but mainly referring to FIG. 2, the fixture 100 of the present embodiment includes a body part 120 and a body part 120 in which a collar 122 having a predetermined length is formed in an upper end area. It includes a screw 130 formed in a spiral on the outer surface.

At this time, the screw portion 130, unlike the prior art, the body at the point where the wide screw portion 131 and the wide screw portion 131 is formed along the longitudinal direction of the body portion 120 from the end of the implantation (lower end region of Figure 2) It includes a narrow screw portion 133 is formed to the collar region of the portion 120, but is formed narrower than the width of the pitch interval of the wide screw portion 131.

Body portion 120 is a portion forming a central stem in the fixture 100 of the present embodiment. The outer surface of the body portion 120 of the fixture 100 implanted in the direction of the arrow of FIG. 1 has a straight straight structure, but in this embodiment, the body portion 120 is partially so that the diameter becomes narrower from the upper end to the lower end. It has a tapered shape.

That is, in the conventional fixture, the body portion (not shown) is a cylindrical structure having a cylindrical type having the same cross-sectional diameter in the longitudinal direction, and the body portion 120 is the upper portion to the lower portion in the fixture 100 of the present embodiment. It has a partially tapered shape so as to narrow in diameter. As such, the body part 120 has a tapered structure, thereby providing an advantage of smoothing the implantation.

In the case of the fixture 100 of the present embodiment, the body portion 120 may be used during implantation while maintaining the size thereof but varying only the size of the screw portion 130 formed on the outer surface of the body portion 120. In this case, when a small sized fixture is loose, the fixture may be removed and a larger fixture may be placed in place. In order to implant a fixture larger than the first fixture without additional drilling and without surrounding alveolar bone damage, the body 120 must be kept at the same size at least. will be.

A collar 122 is formed in the upper region of the body 120. The length of the collar 122 can be selected from 1.0 mm to 1.5 mm. In the case of this embodiment, the length of the collar 122 is selected to be 1.2 mm.

In the prior art, a fixture (not shown) having a length of the collar 122 of 1.8 mm or 2.8 mm has been used. In this case, although there is a limitation of the operation by a limited surgical method, the length of the collar 122 is 1.0 mm to By selecting 1.5 mm, in particular 1.2 mm, the surgery for the fixture 100 to be immersed in the gum, that is, submerged surgery as shown in FIG. The prosthesis then goes down and becomes an aesthetic prosthesis.

Of course, in the case of the fixture 100 of the present embodiment, even if the length of the collar 122 is shorter than in the related art, as shown in FIG. Surgery is also available.

Taken together, the fixture 100 of this embodiment has a length of 1.0 mm to 1.5 mm, especially 1.2 mm, so that the fixture 100 can be immersed in the gum because the collar 122 has a length of 1.0 mm to 1.5 mm. b)} or surgery where the fixture 100 is exposed to the upper portion of the collar 122 without being immersed in the gum {FIG. 8 (a)} is selectively enabled, and at the time of surgery as shown in FIG. 8 (b) Since the start of the prosthesis goes down, there is an advantage of being an aesthetic prosthesis.

In the present embodiment, the collar 122 is being anodized, but instead of being lowered in height, the collar 122 can provide an effect much better than that of the conventional products in terms of strength.

Anodizing is briefly described. When a metal (component) is placed on the anode and electrolyzed in a dilute-acid solution, an oxide film (aluminum oxide: Al₂O₃) having a great adhesion with the base metal is formed by oxygen generated at the anode. Anodization is a compound word of anode and oxidation. It is different from electroplating parts by hanging them on the cathode. The most representative material of anodization is AL and in addition, anodizing is performed on metallic materials of Mg, Zn, Ti, Ta, Hf, and Nb. In recent years, the use of anodizing on magnesium and titanium materials is also increasing.

A bevel portion 121 is formed in the upper corner portion of the collar 122. The bevel portion 121 serves to provide a strong fixing force due to the prosthesis, that is, contact with the artificial tooth (not shown) in a larger area.

A twist cutting edge portion 123 is provided in the lower end region of the body portion 120.

The twist cutting edge portion 123 is formed in the screw portion 130 along the circumferential direction of the body portion 120, and in particular, is formed in the wide screw portion 131. The twisted cutting edge portion 123 serves to facilitate the placement of the fixture 100 due to its sharp tip.

In particular, the twisted cutting edge portion 123 enables smooth self tapping while minimizing resistance due to sequential cutting during placement.

The twist cutting edge portion 123 may be formed on the wide screw portion 131 having a direction inclined to one side with respect to the longitudinal direction of the body portion 120, a plurality of at equal intervals on the outer surface of the body portion 120. For example, two may be formed.

Of course, since such contents may not limit the scope of the present invention, the twist cutting edge portion 123 does not necessarily need to be formed on the outer surface of the body portion 120.

On the other hand, the screw portion 130 is formed on the outer surface of the body portion 120, the pitch pitch (P1, P2, Fig. 2 different from each other in the longitudinal direction of the body portion 120 from the implantation end (lower end region of Figure 2) And a wide screw portion 131 and a narrow screw portion 133 having a shape.

In this case, the pitch spacing P1 (see FIG. 2) between the wide screw portions 131 may be 1.5 to 2.5 times, preferably 2 times, the pitch spacing P2 between the narrow screw portions 133.

The wide screw portion 131 may be formed of a square screw as shown in FIG. 6A, and the narrow screw portion 133 may be formed of a triangular screw as shown in FIG. 6B.

Referring to (a) of FIG. 6, the wide screw portion 131 may be a square screw, but the inclination angles θ1, with respect to the upper surface 131b and the lower surface 131c which are mutually opened based on the vertical surface 131a of the tip portion. θ2) may be different from each other.

For example, when the inclination angle θ1 between the vertical surface 131a and the upper surface 131b of the wide end of the wide screw portion 131 is 80 degrees, the inclination angle θ2 between the vertical surface 131a and the lower surface 131c of the front end portion May be 75 degrees. As a result, the inclination angle θ1 between the vertical surface 131a and the upper surface 131b of the tip of the wide screw portion 131 is the inclination angle between the vertical surface 131a and the lower surface 131c of the tip of the wide screw portion 131. It may be greater than (θ2).

The gap angle θ3 of the narrow screw portion 133, which may be a triangular screw, may be about 50 degrees to 70 degrees, preferably about 60 degrees.

Referring to FIG. 2, the lowermost narrowest screw portion 133 ′ of the lowermost portion of the narrower screw portion 133 is partially overlapped with the uppermost widest screw portion 131 ′ of the uppermost screw portion 131. This is to give continuity to the wide screw portion 131 and the narrow screw portion 133.

And the body portion 120 itself has a tapered shape, and as the wide screw portion 131 and the narrow screw portion 133 is formed for each section on the outer surface of the body portion 120 in the front end of the screw portion (130) The depth to the outer surface of the 120 may be gradually increased toward the end of the body portion 120 is placed.

In other words, the thread depth of the wide screw portion 131 side is larger than the thread depth of the narrow screw portion 133 side, and the depth of the screw thread increases from the wide thread portion 131 side downward. This structure enables smooth self tapping during placement and ensures a strong initial holding force after placement.

Meanwhile, referring to FIG. 3, the imaginary outer line connecting the ends of the mountains of the thread part 130 is gradually expanded from the placement end of the body part 120 toward the collar 122 area of the body part 120. The first tapered section 130a to be provided, the vertical section 130b provided vertically along the longitudinal direction of the body portion 120 at the point where the first tapered section 130a ends, and the vertical section 130b ends. The second taper section 130c is provided to be gradually expanded toward the collar region of the body 120 at the point.

The vertical section 130b serves to facilitate the placement of the fixture 100, and the first taper section 130a and the second taper section 130c serve to reinforce the initial fixing force. In particular, the first tapered section 130a helps to determine the safe placement position while providing convenience of initial entry.

As such, the threaded portion 130 formed on the outer surface of the body portion 120 is formed of a wide screw portion 131 and a narrow screw portion 133 having different pitch spacings (P1, P2, see FIG. 2) and shapes, When the chew 100 is placed, the implantation time can be shortened to minimize the present stress (bone stress) and provide excellent initial fixation force. The installation time can be shortened on the narrow screw portion 133 side, and the initial fixing force can be secured on the wide screw portion 131 side.

In this embodiment, the screw unit 130 may be RBM blasted. The RBM blasting treatment refers to a surface treatment using Ca-P powder, but has an advantage of excellent strength.

Meanwhile, referring to FIG. 4, the abutment coupling part 150 is further provided at an inner region of the upper end portion of the body 120 so that the abutment 200 (Abutment, see FIG. 7) is coupled thereto.

Referring briefly to the abutment 200 with reference to FIG. 7 first, the abutment body 210 having a truncated cone shape and having a through hole 210a formed therein, and a primary coupling formed at a lower end of the abutment body 210. The unit 220 and the secondary coupling unit 230 formed at the lower end of the primary coupling unit 220. Primary coupling portion 220 is a portion that is coupled while being fitted to the primary depression 151 of the abutment coupling portion 150 to be described later, the secondary coupling portion 230 is a secondary depression of the abutment coupling portion 150 It is a part that is coupled to the fitting portion 152. As described later, since the inner wall of the primary depression 151 forms a tapered wall 151a, the primary coupling portion 220 of the abutment 200 also has an outer surface tapered with the same slope as the tapered wall 151a, The shape of the secondary coupling portion 230 is provided in the same manner as the shape of the secondary depression 152.

The abutment coupling part 150 to which the abutment 200 of such a structure is coupled includes a first depression 151 which is primarily recessed along the longitudinal direction of the body part 120 at an upper end of the body part 120, and 1. Second depressions 152 and secondary depressions 152 which are recessed deeper in the longitudinal direction of the body portion 120 at the lower end of the primary depression 151 but are formed in a wave shape along the circumferential direction, and the secondary depressions 152. It is formed along the longitudinal direction of the body portion 120 in the central region of the abutment screw (abutment screw, not shown) for coupling the abutment 200 is provided with a screw groove 153 is fastened.

The primary depression 151 is a portion to which the primary coupling portion 220 of the abutment 200 (see FIG. 7) is coupled. At this time, the primary coupling portion 220 of the abutment 200 should be a strong coupling or close coupling within the primary depression 151 of the fixture 100, a strong coupling is made so that the coupling is not well loosened, Sealing (sealing) should be tightly coupled to eliminate the fear of infection.

Thus, the inner wall of the primary depression 151 forms a tapered taper wall 151a so that the diameter gradually narrows from the upper end to the lower end. The inclination angle of the tapered wall 151a may be in the range of 2 degrees to 6 degrees, similar to the inclination angle of the outer surface of the primary coupling portion 220 of the abutment 200. As such a range, the tapered wall 151a may be formed. When the primary depression 151 is processed and the abutment 200 is coupled thereto, the primary engagement portion 220 of the abutment 200 is strongly bonded or closely adhered to the primary depression 151 where the tapered wall 151a is formed. Can be combined.

The secondary depression 152 is a portion to which the secondary coupling portion 230 of the abutment 200 that has passed through the primary depression 151 is fitted while being fitted to fit. As shown in FIG. 7, when the secondary coupling portion 230 of the abutment 200 is formed into a wave shape, the secondary recess 152 also has a wave shape along the circumferential direction, for example, so that the secondary coupling portion 230 may be shaped accordingly. It can be formed into an octagonal wave shape. However, the scope of the present invention need not be limited to the shape thereof. As such, the secondary coupling portion 230 of the abutment 200 is fitted to be fitted to the second recess 152 to prevent rotation of the abutment 200.

Screw groove 153 is the primary coupling portion 220 and the secondary coupling portion 230 of the abutment 200 to the primary depression 151 and the secondary depression 152 of the abutment coupling portion 150 When each is fitted while being coupled, the abutment screw (abutment screw, not shown) passing through the through hole 210a of the abutment 200 is fastened. The screw groove 153 is manufactured to the same size as the through hole 210a of the abutment 200.

Looking briefly about the implant procedure using the fixture 100 having such a configuration as follows.

First, a drill hole H having a shape as shown in FIG. 1 is formed by drilling a mounting position using a predetermined drill. At this time, the diameter of the drill groove (H) does not need to be drilled narrowly, it may be formed at the level of the conventional drill groove (H), that is, the size level of the fixture (100).

Next, the fixture 100 of the present embodiment is placed at the implantation position, and the fixture 100 is inserted into the drill groove H of the alveolar bone to be implanted.

When the fixture 100 is implanted as described above, the implant is implanted by the structural features of the wide screw portion 131 and the narrow screw portion 133 together with the twist cutting edge portion 123. In this case, the implant time is shortened and thus the bone stress is reduced. It can provide a good initial fixing force with minimal).

In particular, in the case of the fixture 100 of the present embodiment, since the length of the collar 122 is 1.0 mm to 1.5 mm, especially 1.2 mm, the surgery for the fixture 100 to be immersed in the gums {FIG. 8 (b) )} Or surgery where the fixture 100 is exposed to the upper portion of the collar 122 without being immersed in the gum {FIG. 8 (a)} is selectively possible, and during the operation as shown in FIG. Since the beginning of the downward movement has the advantage of being an aesthetic prosthesis.

When the implantation of the fixture 100 is completed and the time for the bone fusion to the fixture 100 proceeds, the abutment 200 is coupled to the abutment coupling part 150 of the fixture 100. Let's do it. Then, the implant procedure is completed by applying the final prosthesis to the abutment 200.

According to the fixture 100 of the present embodiment having such a structure, it is possible to provide an excellent initial fixing force while minimizing bone stress by shortening the implantation time.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
