Description

A T-Base for Dantal Implants ", in which the scope of application of the prosthesis is expanded,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a T-Base for guiding mutual coupling with a prosthesis inserted into a fixture placed in a patient's alveolar bone, and more particularly, Minimizes the size of the prosthesis and makes it possible to apply the prosthesis to a small size prosthesis. The proposed technique is applicable to both submerged type and internal type tee bases. Especially, The present invention also relates to a toothbrush for an implant which can be applied quickly and easily without any separate fastening parts.

Recently, there has been a tendency to develop an implant treatment method which can obtain sufficient strength and esthetics similar to natural teeth by dental medical treatment.

Typically, the implant is composed of a fixture fixed to the alveolar bone for basic framing, a T-base for connecting the fixture and the prosthesis, a crown restoring the outer shape of the removed tooth, ).

The above implants produce a fixture and a titanium base of a certain standardized size through various data acquired during the procedure. However, it was not possible to apply it to all patients with diverse conditions only by the universalized standard.

For example, when a general tee base is used for molars whose heights are somewhat lower than those of other teeth, there is a problem that the upper end of the tee base is exposed to the upper portion of the prosthesis, making the procedure impossible.

Even in this situation, the improved database has not been developed to date. For example, Japanese Patent Laid-Open Publication No. 10-2010-0016217 entitled "Abutment for Implant" is published as an example of a titanium base, and the related art has a structure of an implant including a threaded portion, And a tapered portion is formed on an upper portion of the threaded portion so as to be inserted into and contacted with the tapered portion of the fixture, and the upper head portion is formed on the upper portion of the tightened portion so that the prosthesis can be engaged . Particularly, the above prior art is a configuration in which a plurality of grooves are formed along the circumferential direction so that the contact portion is more tightly contacted with the taper portion of the fixture.

As described above, the tee base generally comprises a threaded portion, a tightly coupled portion, and a head portion. In particular, the head portion has a shape protruding upward by a predetermined height for tight coupling with the prosthesis. Therefore, since a portion of the head portion is exposed to the upper side of the prosthesis in the case of a prosthesis having a low height, there is a limitation in use.

As another example of the titanium base, Japanese Patent Application Laid-Open No. 10-2008-0115021 entitled "Implant abutment" is inserted into the upper fixing groove formed on the upper part of the fixture, the diameter becomes narrower toward the lower side, An abutment body in the form of an inverted triangular pyramid located at the lower part of the lower part of the butt and a lower part of the lower abutment and an outer lower part of the ring shaped abutment made of the ceramic material located at one side lower part of the upper abutment body As a technology, the height of the upper part is lower than that of general abutment.

However, the bonding strength between the abutment body and the outer bottom of the abutment and the bonding strength between the abutment body and the prosthesis are not robust, which is a somewhat lacking technique for the implant.

For the above reasons, it is necessary to assemble easily between the fixture, the tee base and the prosthesis, but it is necessary to have a very strong bonding force and to minimize the upper height of the tee base and to expand the application range of the prostheses provided in various sizes It is a fact that is demanded.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings, in which: FIG.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent by reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. And throughout this specification, like reference numerals refer to like elements throughout.

The present invention relates to a titanium base for guiding mutual coupling with a prosthesis inserted and inserted into a fixture placed in an alveolar bone of a patient.

In addition to minimizing the upper structure of the tee base to which the prosthesis is attached, it is possible to perform the procedure on a small prosthesis of a size that is difficult to implant, and the proposed technique can be applied to both the submerged type and internal type tee bases And more particularly relates to a toothbrush for an implant in which the range of application of a prosthesis that can be quickly and easily performed without providing a separate fastening part is further extended by providing a coupling method that is easily detachable between the tooth base and the prosthesis.

1 is a perspective view of a conventional tee base according to the prior art.

As shown in FIG. 1, the conventional tee base has a fixing part A which is fixed to the fixture 1 in an installed state, a fixing part A which protrudes upward from the fastening part, And a head portion C extending upward from the upper portion of the body portion and interposed between the body portion and the prosthesis 3.

In the prior art titanium base having the above structure, since the height of the head portion C is increased, the area facing the inner diameter of the prosthesis 3 is expanded, and the assembly can be firmly performed by the friction of the opposing areas. The setting became one of the prerequisites for the production of the tee base.

However, although the above-mentioned conventional base can improve the bonding force with the prosthesis, as the size of the prosthesis becomes smaller, the part of the fastening part (3) which firmly connects the prosthesis and the fixture is exposed to the upper part of the prosthesis Implant treatment was impossible. For this reason, the existing titanium base has a limited range of the prostheses provided in various sizes depending on various physical conditions of the patient.

Therefore, the present invention is intended to provide a tibial prosthesis which can be operated without exposing the fastening parts 3 even in a prosthesis having such a small size that the implant treatment is impossible.

FIG. 2 is a perspective view of a tibia of a submerged type in which a range of application of a prosthesis according to a preferred embodiment of the present invention is extended. FIG. 3 is a perspective view showing a combination of a fixture and a prosthesis using a submerged type titanium base. FIG. 5 is a perspective view of an internal type tee base in which a range of application of a prosthesis according to a preferred embodiment of the present invention is extended, and FIG. 6 is a perspective view of an internal type tee And shows the coupling relationship between the fixture and the prosthesis.

As shown in FIG. 2 or 5, the tee base of the present invention includes a fastening portion 10 to be engaged with a fixture, an entry portion 20 to be seated at an upper end of an inner diameter of the fixture, An extension part 30 for dividing the boundary between the prostheses 2 and a mounting part 40 inserted into the inner diameter of the prosthesis and a locking part 42 fitted into the fitting groove 2a formed in the inner diameter of the inserted prosthesis 50).

The upper fastening part 10 is composed of a column having a shape corresponding to the fastening hole 1a of the fixture so that the fastening part 10 can be inserted into the fixture 1 placed in the alveolar bone of the patient. But this is related to one embodiment, and it may be made of a circular column. However, since the abutment rotates in the insertion hole of the fixture and the correct insertion direction of the prosthesis 2 is lost, there is at least one plane, It is preferable to prevent rotation of the motor.

The upper entrance 20 is formed to protrude upward from the upper portion of the fastening portion 10 so as to correspond to the depth of the fastening hole 1a of the fixture 1. Particularly the upper entrance 20 has a diameter There is a gradually expanding taper.

The taper of the upper entrance 20 has an angle of 5 to 10 degrees. The entrance 20 having such a shape stably stays in the fastening hole 1a of the fixture, and the inner diameter of the fixture Allows a large area to be abutted to ensure a firm bond.

The upper extended portion 30 is formed to have a very thin thickness at the upper end of the entry portion 20 and is formed to have a diameter slightly larger than the upper diameter of the fastening portion. The upper extension blade 30 helps the implant practitioner to distinguish the fixture coupling area of the tooth base from the coupling area of the prosthesis even with the naked eye, and also controls the depth at which the tooth base is inserted into the fixture.

The upper mounting portion 40 serves to guide the tee base 100 to be inserted into the inner diameter of the prosthesis 2. Particularly when the upper mounting portion is formed to protrude upward from the center portion of the extending portion 30, Type, and when the upper mounting portion is formed to have the same thickness as the extended portion and protruded downward along the circumference of the extended portion, it is divided into an internal type.

The upper surge-type mounting portion 40 is tapered so that its diameter becomes gradually narrower as it protrudes upward from the extended blade portion 30, thereby facilitating the insertion of the prosthesis 2. The internal-type mounting portion 40 So that the diameter of the tapered portion gradually increases toward the fastening portion 10 from the extended blade portion 20, thereby facilitating the entry of the prosthesis in the same manner as the merge type fastening portion.

In the meantime, the upper surge-type mounting portion 40 is further provided with a cutout groove 41 in the longitudinal or transverse direction from the upper end region to the extended end portion, so as to apply an elastic force to the mounting portion. For example, the mounting portion 40 of the present invention has a somewhat enlarged diameter compared to the inner diameter of the prosthesis 2 and is tightened by interference fit. At this time, the mounting portion divided into a plurality of portions by the cutting groove 41 is prevented In the process of dislodging, each fixture is assembled to the center area by the incision grooves, and the insert fixation is performed.

In addition, the upper internal-type mounting portion 40 is further provided with a cutting groove 41 extending from the bent region to the locking portion 50 to provide an elastic force to the mounting portion. The fastening portion 40 of the upper internal type is likewise made to have a slightly expanded diameter relative to the inner diameter of the prosthesis 2 and is fastened by interference fit. At this time, In the process of fitting, each of the mounts is inserted and fixed while being gathered to the central region starting from the bending region by the cutout groove.

The upper internal type mounting portion 40 further includes a step 42 along the circumference of the extended blade portion in a region where the mounting portion 40 is formed at a right angle in the extended blade portion 30, The area is configured to be somewhat thinner than the thickness of the extended blade part and the mounting part, so that elasticity is provided between the extended blade part and the mounting part.

The upper step 42 is formed by the cutting groove 41 when the tee base 100 is inserted into the inner diameter of the prosthesis 2 by using the elastic force formed between the extended blade 30 and the mounting part 40, This makes it easier to assemble into the area and makes it possible for the mounting part to be returned to the original position again when the tibia is removed from the prosthesis at a later time.

The upper cutting surface 40a is formed with at least one cut surface 40a formed in the central portion of the side surface of the mounting portion 40 where protrusion formation is started in the extended blade portion 30, And actively prevents the prosthesis 2 from rotating in an undesired direction and losing its direction.

In addition, the upper cutting surface 40a may allow a surface that can be securely fixed using a holding tool when connecting the tee base 100 to the fixture 1. [

4 and 7 are cross-sectional views showing the coupling relationship of the tee base according to the present invention.

As shown in FIG. 4, a submerged type tee base 100 includes a locking part 50 protruding outward from an upper end of a mounting part 40.

The upper locking portion 50 is formed along the upper circumference of the mounting portion 40 and the inner diameter of the prosthesis is formed with a fitting groove 2a corresponding to the locking portion in an area where the upper end of the mounting portion reaches something to do.

When the mounting portion 40 enters the inner diameter of the prosthesis, the upper locking portion 50 is pressurized by the inner diameter of the prosthesis and enters the center of the extended portion 30 together with the mounting portion. The locking portion is fitted and fixed in the fitting groove 2a while expanding the reduced mounting portion.

With the above-described structure, the tee base 100 and the prosthesis of the present invention can be easily assembled for the first time, and since the coupling direction or position of the tooth base and the prosthesis can be adjusted in a state where the locking portion and the fitting groove are primarily engaged, Environment can be created.

As shown in FIG. 7, the internal type tee base 100 includes a locking part 50 protruding outward along the circumference of the mounting part 40 at the end of the mounting part protruding to the lower end.

The locking part 50 formed on the tee base 100 of the internal type is also reduced while entering the inside diameter of the prosthesis, and when the locking part 50 reaches the fitting groove 2a formed in the inner diameter of the prosthesis, The locking portion 50 and the fitting groove 2a are mutually joined.

8 is a comparative view showing a range of application of a prosthesis between a tee base of the prior art and a tee base of the present invention.

The implants shown on the left side in FIG. 8 are obtained by applying a titanium base manufactured by a conventional technique, and the implants shown in the middle are those obtained by applying the submerged type titanium base 100 of the present invention, The inner base of the present invention is applied.

As shown in the drawing, the implant to which the tee base 100 fabricated by the technique of the present invention is applied is in a state in which the fastening parts 3 are not exposed to the upper end of the prosthesis, but are accurately inserted into the inner region of the prosthesis.

However, according to the conventional technique, since the upper portion of the abutment is already applied to the upper surface of the fixture 1 by a predetermined height, the space in which the fastening member 3 enters the inner space of the prosthesis is reduced . Therefore, as shown in the drawing, the conventional implant exposes the head of the fastening member 3 to the upper side of the prosthesis 2, which results in a situation that can not be applied to the patient's alveolar bone.

9 is a view showing a further configuration of a locking part according to another embodiment of the present invention.

9, the locking part 50 of the present invention is formed along the circumference at the end of the mounting part 40 and is seated in the fitting groove 2a provided in the inner diameter of the prosthesis 2. The mounting portion 40 of the present invention further includes at least one locking portion 50 spaced apart from the outer periphery of the mounting portion 40 so that the fitting portion 2 has a plurality of fitting grooves A plurality of locking portions and a plurality of fitting grooves are mutually engaged to induce more rigid primary bonding.

10 is a cross-sectional view showing a coupling relation between a seating part formed on an inner diameter of a tee base and a seating protrusion formed on an inner diameter of a prosthesis according to another embodiment of the present invention.

10, the tee base 100 of the present invention includes a through hole 60 extending from the upper end to the lower end for guiding the insertion of the fastening part 3, and the upper through hole 60 is formed at the upper end A seating portion 61 formed to be depressed with a somewhat enlarged diameter is formed and a seating protrusion 2b corresponding to the seating portion 61 is further formed on the inner diameter of the prosthesis 2 so as to be engaged with each other.

In order to positively prevent exposure of the head of the fastening part 3, the titanium base 100 inserted between the inner diameters as described above reinforces the problem that the friction area between the prosthesis 2 and the titanium base decreases as the height of the upper end decreases It is a means for. In other words, since the inner diameter of the tooth base 100 can be utilized as a friction surface between the teeth, even if the upper end of the tooth base is lowered, the coupling force between the tooth base and the tooth 3 can be positively maintained.

11, the inner type tee base 100 according to the present invention has a longitudinal or transverse direction in which a locking portion 50 formed at an end of the mounting portion 40 is provided with respect to an upper end of the extended portion 30, So that the mounting portion of the tee base inserted into the inner diameter of the prosthesis 2 can be more smoothly reduced to the central region.

In the implant type titanium base having the above-described configuration, the implant base is positively inserted into the inner diameter of the fixture, and the maximum height of the titanium base is firstly reduced on the basis of the fixture , The mounting portion is set at a lower height than the existing tee base, and the maximum height of the tee base is secondarily reduced with respect to the fixture. Therefore, even when a prosthesis having a height smaller than the conventional tee base is 0.1 to 0.5 mm in size, In addition, it is possible to positively improve the limit of the range of application of the prosthesis, and furthermore, a taper of 5 to 10 degrees is formed in the mounting portion in which the prosthesis is directly coupled with the prosthesis, It is possible to combine the prosthesis with the tee base without the need of a separate tool by the protruding projections, It is possible to construct an easier working environment for the surgical procedure. In addition, since all the proposed technical features can be applied regardless of the submerged type and the internal type, the technical base of the tee base can be overcome positively.
