Technical Field

The present invention relates to a titanium substrate (T-Base) for guiding the mutual coupling of a prosthesis by the indirect insertion of a fixture implanted in an alveolar bone of a patient, and more particularly, to a titanium substrate for a dental implant which expands the applicable range of a prosthesis, minimizes the upper structure of the titanium substrate to which the prosthesis is coupled, and enables an operation on a small prosthesis having a size that is not easy to handle when performing an operation on the dental implant, and provides a technique applicable to both a buried (surfaced Type) and a built-in (Internal Type) titanium substrate, and particularly, provides a coupling means capable of being conveniently detached between the titanium substrate and the prosthesis, thereby enabling an operation to be rapidly and simply performed without additional coupling accessories.

Background

Recently, as a dental medical surgery method, a dental implant surgery method having sufficient strength and aesthetic quality similar to natural teeth is continuously developed.

Generally, dental implants are formed of the following structure: a Fixture (Fixture) implanted and fixed to the alveolar bone to form a basic skeleton; a titanium substrate (T-Base) which is a component for connecting the fixture and the prosthesis; the prosthesis (Crown) is used instead of the extracted tooth by reducing the shape thereof.

The above dental implant manufactures a fixture and a titanium substrate of a somewhat general specification by means of various data acquired during the operation. However, the above generalized specifications cannot be applied to all patients under various conditions.

For example, when the titanium base is applied to a molar tooth having a slightly lower height than the teeth of other parts, the upper end portion of the titanium base is exposed to the upper portion of the prosthesis, and the operation cannot be performed.

With respect to the above-mentioned situation, a titanium substrate which improves the above-mentioned problems has not been provided so far. For example, as an example of a titanium substrate, a "dental implant abutment" disclosed in japanese laid-open patent publication No. 10-2010-0016217 is disclosed, which is a dental implant including a screw part, an abutment part and a head part, wherein the screw part is formed with a screw thread so as to be screwed into a fixture, the abutment part is formed with a taper in an upper part of the screw part so as to be contacted after being inserted into a taper part of the fixture, and the head part is formed in an upper part of the abutment part so as to be combined with a prosthesis. In particular, in the above-described conventional technique, a plurality of grooves are formed in the circumferential direction in order to bring the close contact portion into close contact with the tapered portion of the anchor.

As described above, in general, the titanium substrate is composed of a screw part, an adhesion part, and a head part, and particularly, the head part is in a shape protruding by a predetermined height so as to be closely combined with the prosthesis.

Therefore, when a prosthesis having a low height is used, a part of the head is exposed to the upper side of the prosthesis, and there is a limitation in use.

As still another example of the titanium substrate, the Japanese laid-open patent publication No. 10-2008-0115021 "dental implant abutment" is formed of: a lower portion of the base station inserted into an upper fixing groove formed at an upper portion of the fixing member, the diameter of which is narrowed toward a lower portion, and an external thread formed at an outer portion; a base main body formed on the upper part of the lower part of the base and formed into an inverted triangle shape; and a lower outer portion of the base formed on one side of the lower portion of the base body, formed of a ceramic material, and having a ring shape.

However, the bonding force between the abutment main body and the outer lower portion of the abutment and the bonding force between the abutment main body and the prosthesis are weak, and thus, the technique has certain disadvantages when being applied to the operation of the dental implant.

Therefore, there is an urgent need for a technique that can easily assemble a fixture with a titanium substrate and a prosthesis, has excellent binding force, and can enlarge the applicable range of prostheses of various sizes by minimizing the upper height of the titanium substrate.

Technical problem to be solved by the invention

In order to effectively eliminate the above-mentioned problems, the present invention provides a technique for minimizing the upper structure of a titanium base into which a prosthesis is inserted, thereby enabling dental implantation on a prosthesis of a smaller size in which a bonded attachment is exposed to the upper region of the prosthesis and dental implantation cannot be performed.

Also, the present invention provides a titanium substrate capable of conveniently separating the prosthesis from the titanium substrate without additional tools.

The above-described technical features are applicable regardless of the type of titanium substrate classified into embedded type and built-in type.

Technical scheme for solving problems

In order to solve the above technical problems, the titanium substrate for dental implants provided by the present invention for expanding the application range of a prosthesis comprises:

the titanium substrate for dental implants of the present invention is formed of the following structure: a combining part 10 formed in a polygonal shape and combined with the fixing member 1; an inlet portion 20 formed to protrude from an upper portion of the coupling portion in a gradually expanding straight radial direction, and disposed at an upper end of an inner diameter of the fixing member; an extended wing part 30 formed at the upper end of the entry part to extend with a diameter enlarged outward for distinguishing the boundary between the fixture and the prosthesis 2; a placement part 40 protruding from the extension wing part to the upper side or the lower side and inserted into the inner diameter of the prosthesis; a locking part 50 formed as a protrusion to the outside along the circumference of the distal end of the placement part and inserted and fixed to the insertion groove 2a formed on the inner diameter of the inserted prosthesis.

And, the placing part 40 is a buried Type (buried Type), that is, a cylinder protruding upward from the central portion of the upper end of the extending wing part 30 to form a predetermined height, and the placing part 40 is further formed with a cut groove 41 formed from the upper end to the extending wing part in a longitudinal or transverse direction to provide elasticity to the placing part.

And, the placing part 40 is formed in a tapered shape of 5 to 10 ° whose diameter is gradually reduced from the extension wing part 30 to the upper side.

And, the placing part 40 is built-in (Internal Type), that is, is formed to protrude downward from the circumference of the extended wing part 30, to pressurize the inner diameter of the prosthesis, and is further formed with a cutting groove 41 formed in a longitudinal or transverse direction from the upper end of the extended wing part 30 to the locking part 50, to provide elasticity to the placing part.

Also, the placement portion 40 is formed in a tapered shape having a diameter gradually increasing from the extension wing portion 30 to the coupling portion 10 by 5 to 10 °.

A stepped rib 42 recessed at a predetermined depth is formed along the circumference of the placement portion 40 at a portion bent downward from the extension wing portion 30, thereby providing an elastic force to the placement portion 40.

The plurality of locking portions 50 are formed at predetermined intervals on the outer peripheral edge of the placement portion 40.

The titanium substrate 100 is formed with a through hole 60 from the upper end to the lower end for guiding the insertion of the coupling attachment 3, and a seating part 61 is formed at the upper end of the through hole 60 to be recessed with a slightly expanded diameter, and a seating protrusion 2b corresponding to the seating part 61 is further formed at the inner diameter of the prosthesis 2, thereby realizing the insertion coupling of the inner diameters thereof.

ADVANTAGEOUS EFFECTS OF INVENTION

The present invention configured as described above has the following effects: the maximum height of the titanium base based on the fixture is reduced once by smoothly inserting the joining part and the entering part into the inner diameter of the fixture, and the maximum height of the titanium base based on the fixture is reduced twice by setting the placing part to a height lower than that of the conventional titanium base, so that the dental implantation can be performed even on a prosthesis having a small size of 0.1 to 0.5mm in height as compared with the conventional titanium base, and the limitation of the application range of the prosthesis is remarkably improved.

The present invention has another effect as follows: a taper of 5 to 10 deg. is formed on the placing part directly combined with the prosthesis to guide the combining with the prosthesis smoothly, and the prosthesis can be combined with the titanium substrate without additional tools by means of the protrusion formed by protruding outward at the distal end of the placing part, thereby enabling to create a more convenient working environment for performing the dental implantation.

Further, the present invention has still another effect as follows: the titanium substrate of the present invention can be applied to all technical features regardless of the embedded type and the built-in type, and therefore, the technical limitation due to the kind of the titanium substrate can be eliminated.

Detailed Description

The structure of the present invention and its operation and effects will be described below with reference to the drawings.

The benefits, features, and methods of attaining them of the present invention will become more apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms, and the embodiments are provided to make the disclosure of the present invention more complete, and to make a person having ordinary skill in the art of the present invention completely understand the scope of the present invention, and the present invention is defined only by the scope of the claims. In addition, the same reference numerals are used to designate the same components throughout the specification.

The present invention relates to a titanium substrate for guiding the mutual combination with a prosthesis by the indirect insertion of a fixture implanted in an alveolar bone of a patient.

More particularly, the present invention relates to a titanium substrate for a dental implant which expands an applicable range of a prosthesis, minimizes an upper structure of the titanium substrate to which the prosthesis is coupled, and enables an operation to be performed on a prosthesis having a small size that is difficult to operate when performing an operation of the dental implant, and the present invention provides a technique applicable to both a buried (plated Type) and a built-in (Internal Type) titanium substrate, and particularly, provides a coupling method capable of being conveniently detached between the titanium substrate and the prosthesis, thereby enabling an operation to be rapidly and simply performed without additional coupling accessories.

Fig. 1 is a perspective view showing a typical titanium substrate according to the prior art.

As shown in fig. 1, the conventional titanium substrate is formed of the following structure: a fixing part (A) which is combined with the fixing part 1 and is fixed in an embedded state; a main body part (B) which is formed to protrude from the joint part to the upper part and has a diameter which gradually expands to the upper part in order to rapidly self-heal with the gum; and a head part (C) extending upward from the upper part of the body part and forming an indirect insertion state with the prosthesis (3).

In the titanium substrate of the conventional art having the above-described structure, the area facing the inner diameter of the prosthesis 3 is enlarged as the height of the head (C) is increased, and the head can be firmly combined by friction of the facing area, and therefore, the height of the head is set as one of the requirements in manufacturing the titanium substrate.

The conventional titanium substrate as described above can improve the bonding force with the prosthesis, but the smaller the size of the prosthesis is, the more a part of the bonding attachment 3 firmly connecting the prosthesis and the fixture is exposed to the upper end of the prosthesis, and therefore, there is a problem that the dental implant operation cannot be performed. The above reasons have made the conventional titanium substrate limit the applicable range of the prosthesis manufactured in various sizes according to various physical conditions of patients.

Accordingly, the present invention provides a titanium substrate which can be used for a prosthesis formed in a small size to the extent that dental implant surgery cannot be performed as described above, and which can prevent the attachment 3 from being exposed.

FIG. 2 is a perspective view of an embedded titanium substrate constructed in accordance with a preferred embodiment of the present invention to expand the applicability of the prosthesis; FIG. 3 is an exploded perspective view showing the use of an embedded titanium substrate to show the attachment of the fastener to the prosthesis; FIG. 5 is a perspective view of a built-in titanium substrate constructed in accordance with a preferred embodiment of the present invention to expand the applicability of the prosthesis; FIG. 6 is an exploded perspective view showing the attachment of the anchor to the prosthesis using a built-in titanium substrate.

As shown in fig. 2 or 5, the titanium substrate of the present invention is formed of the following structure: a coupling portion 10 for guiding coupling with the fixing member; an inlet portion 20 disposed at an upper end of an inner diameter of the fixing member; extending the wings 30, differentiating the demarcation between the fixation element and the prosthesis 2; a placement part 40 inserted to the inner diameter of the prosthesis; a locking part 50 inserted into the insertion groove 2a formed at the inner diameter of the inserted prosthesis.

The coupling part 10 is formed in a pillar shape corresponding to the coupling hole 1a of the fixture in order to insert the fixture 1 implanted into the alveolar bone of the patient, and particularly, the coupling part is shown in a polygonal shape in the present invention, but it is only one embodiment and a circular pillar shape may be manufactured. However, if it is manufactured in a circular pillar shape, the abutment is rotated in the insertion hole of the fixture to lose the exact insertion direction of the prosthesis 2, and therefore, it is preferable to form at least one plane to prevent the titanium substrate 100 from being rotated in the fixture.

The entering portion 20 is formed to protrude upward from the upper portion of the coupling portion 10 so as to correspond to the depth of the coupling hole 1a of the fixing member 1, and particularly, the entering portion 20 is formed in a tapered shape having a diameter gradually enlarged at the upper portion of the coupling portion.

The above-mentioned taper of the entry portion 20 is formed with an angle of 5 to 10 deg., and the entry portion 20 having this shape can be stably seated in not only the coupling hole 1a of the fixing but also be in contact with the inner diameter of the fixing with a larger area to form a strong coupling force.

The extended wing portion 30 is formed to have an extremely thin thickness at the upper end of the inlet portion 20 and to extend with a diameter slightly larger than the upper diameter of the coupling portion. The extended wing part 30 described above not only helps the operator of the dental implant to distinguish the bonding area of the fixture of the titanium substrate from the bonding area of the prosthesis by naked eyes, but also controls the depth of insertion of the titanium substrate into the fixture.

The above-mentioned placing part 40 functions to guide the insertion of the titanium substrate 100 toward the inner diameter of the prosthesis 2, and particularly, if the above-mentioned placing part is formed to protrude upward from the central portion of the extended wing part 30, an embedded type titanium substrate is formed, and if the above-mentioned placing part is formed to protrude downward along the circumference of the extended wing part with the same thickness as the extended wing part, a built-in type titanium substrate is formed.

The above-mentioned embedded type placing part 40 is formed in a tapered shape which is more protruded upward from the extended wing part 30 and has a smaller diameter so that the prosthesis 2 is smoothly inserted, and the built-in type placing part 40 is formed in a tapered shape which is gradually enlarged in diameter from the extended wing part 30 toward the combining part 10, which contributes to smooth entry of the prosthesis as the embedded type placing part is.

Also, the embedded type mounting portion 40 is formed with a longitudinal or lateral cut groove 41 from the upper end region to the extended wing portion, thereby giving elasticity to the mounting portion. For example, the placement part 40 of the present invention is formed with a slightly enlarged diameter compared to the inner diameter of the prosthesis 2, and is bonded by means of an interference fit, and at this time, in the case of a plurality of divided placement parts by means of the cutting grooves 41, the respective placement parts are gathered toward the central region by means of the cutting grooves during the interference fit, and insertion fixation can be completed.

Also, the built-in placing part 40 is formed with a cut groove 41 from a bent region with the extension wing part 30 to the locking part 50 to provide an elastic force to the placing part. The built-in placement part 40 is also formed with a slightly enlarged diameter compared to the inner diameter of the prosthesis 2 and is bonded by interference fit, and at this time, in the process of interference fit with a plurality of divided placement parts by means of the cutting grooves 41, the respective placement parts are gathered from the curved region toward the central region by means of the cutting grooves, and insertion fixation is completed.

In the built-in placement portion 40, a stepped ridge 42 is further formed along the circumference of the extension wing portion in a region where the placement portion 40 is formed at a right angle from the extension wing portion 30, so that the corresponding region is formed to be slightly thinner than the thicknesses of the extension wing portion and the placement portion by the stepped ridge, thereby providing elasticity between the extension wing portion and the placement portion.

The stepped ridges 42 make the placement portion gather more smoothly toward the central area by means of the cutting grooves 41 when the titanium base 100 is inserted into the inner diameter of the prosthesis 2, using the elastic force formed between the extended wing portions 30 and the placement portion 40, and make the placement portion restore to the original shape again quickly even when the prosthesis is detached from the titanium base.

Furthermore, the side surface of the placing part 40 formed by projecting from the extended wing part 30 is formed with at least one cutting surface 40a cut to the central part side, and the cutting surface 40a can effectively prevent the prosthesis 2 inserted and combined from being unintentionally rotated and losing its direction.

The cut surface 40a contributes to firm fixation by a holding tool when the titanium substrate 100 and the fixture 1 are connected.

Fig. 4 and 7 are sectional views showing the bonding relationship of the titanium substrate of the present invention.

As shown in fig. 4, the embedded titanium substrate 100 is formed with a locking portion 50 formed to protrude outward at an upper end portion of the placement portion 40.

The above locking part 50 is formed along the upper end circumference of the placing part 40, and an insertion groove 2a of a shape corresponding to the locking part is also formed at a region of the inner diameter of the prosthesis contacting the upper end of the placing part.

The above-mentioned locking part 50 is pressed by the inner diameter of the prosthesis when the placing part 40 enters the inner diameter of the prosthesis, and after entering in a state where the central area of the wing part 30 extended together with the placing part is contracted, the contracted placing part is expanded when the locking part reaches the insertion groove 2a formed in the inner diameter of the prosthesis, so that the locking part is inserted and fixed to the insertion groove 2 a.

With the above configuration, the titanium substrate 100 of the present invention can be easily combined with the prosthesis in an initial stage, and the combining direction and position of the titanium substrate and the prosthesis are adjusted in a state where the locking part and the insertion groove are first combined, thereby enabling to create a more convenient surgical environment.

As shown in fig. 7, the built-in titanium substrate 100 is formed with a locking portion 50 formed to protrude in an outer side direction along the circumference of the placement portion 40 at the tip of the placement portion formed to protrude toward the lower end.

The locking part 50 formed at the above built-in titanium substrate 100 is also contracted when entering the inner diameter of the prosthesis, and when reaching the insertion groove 2a formed at the inner diameter of the prosthesis, the contracted placing part 40 is expanded to be able to combine the locking part 50 and the insertion groove 2a with each other.

Fig. 8 is a graph showing a comparison of the prosthesis application ranges between the titanium substrate of the prior art and the titanium substrate of the present invention.

In fig. 8, the dental implant shown on the left side shows a titanium substrate to which the titanium substrate manufactured by the conventional technique is applied, the dental implant shown in the middle shows an embedded titanium substrate 100 to which the present invention is applied, and the dental implant shown on the rightmost side shows a built-in titanium substrate to which the present invention is applied.

As shown in the drawings, the dental implant to which the titanium substrate 100 manufactured by the technique of the present invention is applied can prevent the bonding attachment 3 from being exposed to the upper end portion of the prosthesis to be formed in a state of being accurately inserted in the inner region of the prosthesis.

However, in the dental implant for operation according to the conventional technique, the upper portion of the abutment is already formed at a predetermined height above the fixture 1, and therefore, the space for the attachment 3 to enter the inner space of the prosthesis is relatively reduced. Accordingly, as shown in the drawing, the head of the coupling fixture 3 of the conventional dental implant is exposed to the upper side of the prosthesis 2, and thus the dental implant cannot be applied to the alveolar bone of the patient.

Fig. 9 shows an additional configuration of a locking portion of another embodiment of the present invention.

As shown in fig. 9, the locking part 50 of the present invention is formed along the circumference at the distal end of the placement part 40 while being seated in the insertion groove 2a formed in the inner diameter of the prosthesis 2. Here, the placing part 40 of the present invention is additionally formed with at least one or more locking parts 50 at the outer circumference thereof at intervals, and is additionally formed with a plurality of insertion grooves 2a at the same positions as the arrangement of the locking parts at the inner diameter of the prosthesis 2 corresponding thereto, thereby guiding the plurality of locking parts and the plurality of insertion grooves to be more firmly combined with each other at one time.

FIG. 10 is a sectional view showing a coupling relationship between the placement portion formed on the inner diameter of the titanium substrate constructed in accordance with still another embodiment of the present invention and the placement projection formed on the inner diameter of the prosthesis.

As shown in FIG. 10, the titanium substrate 100 of the present invention comprises a through hole 60 formed from the upper end to the lower end for guiding the insertion of the coupling appendage 3, and a seating part 61 formed concavely with a slightly enlarged diameter is formed at the upper end of the through hole 60, and a seating projection 2b corresponding to the seating part 61 is further formed at the inner diameter of the prosthesis 2, thereby achieving the insertion coupling to the inner diameter therebetween.

The titanium substrate 100 inserted between the inner diameters as described above is a convenient means for improving the reduction of the friction area between the prosthesis 2 and the titanium substrate by setting the height of the upper end portion to a low shape in order to effectively prevent the head of the coupling attachment 3 from being exposed. That is, the inner diameter of the titanium substrate 100 can be used as a frictional surface with the prosthesis, so that even if the upper end portion of the titanium substrate becomes low, the bonding force of the titanium substrate with the prosthesis 3 can be firmly maintained as before.

As shown in fig. 11, the built-in titanium base 100 of the present invention is formed with a cut part 41 in a lateral or longitudinal direction from the upper end of the extended wing part 30 to the locking part 50 formed at the distal end of the placement part 40, thereby allowing the placement part of the titanium base inserted toward the inner diameter of the prosthesis 2 to be more smoothly contracted toward the central region.

The titanium base for dental implant of the present invention, which is configured as described above and expands the applicable range of the prosthesis, can make the combining part and the entering part smoothly inserted into the inner diameter of the fixture, and the maximum height of the titanium base is once reduced based on the fixture, and the maximum height of the titanium base can be secondarily reduced based on the fixture by setting the placing part to a height lower than the conventional titanium base, so that the dental implant operation can be performed for a large and small prosthesis having a height of 0.1 to 0.5mm compared to the conventional titanium base, and the limitation of the applicable range of the prosthesis is greatly improved, and the placing part directly combined with the prosthesis is formed with a taper of 5 to 10 degrees to smoothly guide the combination with the prosthesis, and by means of the protrusion protruding outward at the tip of the placing part, the prosthesis can be bonded to the titanium substrate without additional tools and create a more convenient working environment for performing dental implant surgery. Further, the titanium substrate of the present invention can be applied to all technical features regardless of the embedded type or the built-in type, and therefore, the technical restriction according to the kind of the titanium substrate can be eliminated.
