Dental implant component with elastic fault tolerance

The present invention relates to a dental implant component having an elastic structure, in particular, a resilient fault-tolerant portion in the abutment limiting portion, which can correct and tolerate the elastic fault-tolerant portion for the angular deviation of the dental implant or the tolerance generated during the production. Dental implant component

In the 1950s, a Swedish physician discovered in a karma that three months after he implanted a titanium screw into the rabbit's thigh bone, he could not reverse the screw and turn it out. The possibility of roots. In 1965, the first artificial dental implant surgery was carried out, and a new page of dental medicine was also unveiled.

Referring to the first and second figures, the first figure shows an exploded view of the prior art dental implant component; the second figure shows the exploded view of the prior art dental implant component. As shown in the figure, the prior art is a dental implant assembly comprising an implant PA1, an abutment PA2, and a locking member PA3. The implant PA1 extends along the implant axis PAA1, and There is an implanted groove PA11 and a locking channel PA12. The abutment PA2 extends along an abutment axial axis PAA2 and has a body passage PA21 and a tapered engagement portion PA22.

Please refer to the third figure. The third figure shows a schematic cross-sectional view of the dental implant component with the locking channel tolerance in the prior art. As shown in the figure, if the abutment PA2 is made, the support passage PA21 has a tolerance angle with the abutment axial PAA2 due to various factors, so that the locking object PA3 After the insertion of the support channel PA21, it will be stuck in the implantation groove PA11, and it cannot be accurately screwed to the locking channel PA12, so that the dentist increases the risk of surgical failure during the implant operation.

In addition, please refer to the fourth figure, which is a schematic cross-sectional view showing the state of the implant of the prior art continuous crown. As shown in the figure, since the continuous crown PA4 is simultaneously fixed to the three abutment branches PA2, it is difficult for the abutment PA2 to change its implantation angle when implanting the above-mentioned implant PA1. Therefore, once there is a deviation angle PAAN between the implant axial direction PAA1 and the abutment support axial direction PAA2, the position of the passage opening of the locking passage PA12 and the passage opening of the support passage PA21 cannot be matched, resulting in a There is a bias error. When there is a misalignment error between the passage opening of the locking passage PA12 and the passage opening of the support passage PA21, the tapered engaging portion PA22 cannot be completely inserted into the implantation groove PA11. At this time, the locking object PA3 is caught in the implantation groove PA11 after passing through the support passage PA21 and cannot be screwed to the locking passage PA12. As a result, the angular deviation of the continuous crown PA4 is not allowed. In other words, once there is a deviation angle, implant surgery is likely to fail.

In the prior art, in addition to the dentist's need to accurately implant the implant into the alveolar bone, the implant component manufacturer must also manufacture the dental implant component without any problems, so that the dental implant can be successfully performed once the dentist is in There are some slight deviations in implanting the implant PA1, or the tolerance of the implant component manufacturer during production, which has a huge impact on the implant surgery.

In the dental implant assembly provided by the prior art, it is difficult to cope with effective fault tolerance fine adjustment for tolerances generated at the time of manufacture. In addition, when performing continuous dental crown implant surgery, if it is implanted When the implant is inserted into the implant, the angle of the implant is slightly different, which will greatly increase the chance of failure of the implant surgery. The above situation is an urgent problem that dental medicine is currently trying to solve.

In order to solve the problems existing in the prior art, the necessary technical means adopted by the present invention is to provide a dental implant component having a resilient fault-tolerant portion, which is disposed on a alveolar bone, and the dental implant component having the elastic fault-tolerant portion It includes an implant, an abutment and a locking element.

The implant body is disposed on the alveolar bone, and has a tapered limiting groove extending along an axial direction of the implant body, and the tapered limiting groove is surrounded by a limiting groove wall, and the limiting groove wall and the limiting groove wall are The implant axial system has a groove wall inclination angle. The abutment is disposed on the implant and has an abutment axial direction and includes a tapered limiting portion and a plurality of elastic fault-tolerant portions. The tapered limiting portion extends along the axial direction of the abutment and is received in the tapered limiting slot and has a tapered limiting wall. The tapered limiting wall and the abutment axial direction have an abutment limit inclination angle. The elastic fault-tolerant portion includes a plurality of elastic fault-tolerant structures extending from the tapered limiting portion, and is erroneously accommodated in the tapered limiting slot. The locking component is disposed on the abutment and fixed to the implant so that the abutment is fixed on the implant by the locking component

In addition, the inclination angle of the groove wall is smaller than the inclination angle of the abutment limit, and when the abutment is combined with the implant to generate a bias error between the implant and the implant, the elastic fault-tolerant structure is elastically deformed to reduce the misalignment error.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the elastic fault-tolerant portion has a fault-tolerant tilt angle with respect to the axial direction of the abutment, and the tolerance tilt angle ranges from 0 to 45 degrees.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the elastic fault-tolerant structure is a plurality of elastic fault-tolerant elastic pieces which are mutually spaced.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the tapered limiting groove is a polygonal tapered limiting groove.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the tapered limiting portion is a polygonal tapered limiting portion.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the implant is composed of a metal material.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the implant has an external thread, and the extracorporeal thread is screwed to the alveolar bone.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the implant body is provided with a locking portion, and the locking component is locked to the locking portion.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the locking portion is a screw hole.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the locking element is a screw.

In the dental implant assembly with the elastic fault-tolerant portion provided by the present invention, the elastic fault-tolerant structure extending from the tapered limiting portion can deflect the angle and position of the implant into the implant in a fault-tolerant manner. Therefore, when tolerance occurs in the abutment channel in the dental implant component having the elastic fault-tolerant portion, the implantation angle of the abutment can be finely adjusted by bending the elastic fault-tolerant portion so that the abutment channel can be parallel to the implant axial direction. The locking element can be smoothly screwed to the locking portion.

In addition, in the dental implant surgery of the continuous crown, if the implant is implanted in the alveolar bone, there is an error in the angle of the implant, and the tapered limit portion can be further deepened by bending the elastic fault-tolerant structure. Place the cone into the tapered limit groove. The tapered limiting portion is further inserted into the tapered limiting groove, so that the abutment passage opening and the locking opening are close to each other. Further, the locking element is screwed into the locking port from the abutment passage opening, so that the locking component is more smoothly screwed to the locking portion.

Therefore, after the implementation of the dental implant component with the elastic fault-tolerant portion provided by the present invention, not only the prior art is solved, because when the dental implant is assembled, the locking object cannot be screwed into the lock due to manufacturing tolerances. The problem of the solid channel also solves the problem of the angular error of the implant when implanting the alveolar bone during the continuous crown implant operation, which makes it difficult to completely insert the tapered engaging portion into the implantation groove. In short, this creation further increases the fault tolerance of implant surgery, which means increasing the chances of successful implant surgery.

The related embodiments of the dental implant assembly having the elastic fault-tolerant portion provided by the present invention are numerous, and therefore will not be further described herein, and only two preferred embodiments will be specifically described.

Please refer to FIG. 5A to FIG. 7 together. FIG. 5A is a perspective exploded view showing the dental implant component with the elastic fault-tolerant portion of the first embodiment of the present invention; A perspective view of an abutment of a dental implant component having an elastic fault-tolerant portion according to an embodiment; and a sixth perspective view showing a stereoscopic display of the dental implant component having the elastic fault-tolerant portion of the first embodiment of the present invention The seventh drawing shows an exploded cross-sectional view of the dental implant assembly having the elastic fault-tolerant portion of the first embodiment of the present invention. As shown in the figure, the first embodiment of the present invention provides a dental implant assembly 1 having an elastic fault-tolerant portion, which is disposed on a alveolar bone, and the dental implant assembly 1 having an elastic fault-tolerant portion includes an implant 11 An abutment 12 and a locking element 13.

The implant 11 is disposed on the alveolar bone and is provided with a tapered limiting slot 111, an extracorporeal thread 112 and a locking portion 113. The tapered limiting slot 111 extends along an implant axis A1 and is surrounded by a limiting slot wall 1111 and a limiting slot bottom 1112. The limiting slot wall 1111 (such as the limiting slot wall extension) Line L1) has a groove wall inclination angle AN1 with the implant axial direction A1. It is worth mentioning that the tapered limiting slot 111 is a polygonal tapered limiting slot, such as a quadrangular tapered limiting slot, a pentagon tapered limiting slot and a hexagonal tapered limiting slot, but not This is limited to this. The extracorporeal thread 112 is threaded onto the alveolar bone. In addition, the locking portion 113 further includes a locking opening 1131. Further, the locking portion 113 is a screw hole. Incidentally, the implant 11 is made of a metal material, such as titanium metal, but not limited thereto.

The abutment 12 is disposed on the implant 11 and has an abutment axial direction A2 and includes a tapered limiting portion 121 and a plurality of elastic fault-tolerant portions 122. The tapered limiting portion 121 extends along an abutment axial direction A2 and is received in the tapered limiting slot 111 and has a tapered limiting wall 1211, an abutment channel 1212 and an abutment channel opening 1213. The tapered limiting portion 121 is a polygonal tapered limiting portion, and the tapered limiting slot 111 is, for example, a quadrangular tapered limiting slot, a pentagon tapered limiting slot, and a hexagonal tapered limiting slot, but Not limited to this.

The tapered limiting wall 1211 (shown by the tapered limiting wall extension line L2) and the abutting axial direction A2 have an abutment limit inclination angle AN2. The elastic fault-tolerant portion 122 includes a resilient fault-tolerant structure 1221 extending from the tapered limiting portion 121 and is erroneously received in the tapered limiting slot 111. In addition, the elastic fault-tolerant structure 1221 has a fault-tolerant tilt angle with the abutment axial direction A2, wherein the fault-tolerant tilt angle ranges from 0 to 45 degrees. It is further explained that the elastic fault-tolerant structure 1221 is a plurality of elastic fault-tolerant elastic pieces which are mutually spaced.

The locking element 13 is threaded through the abutment 12 and fixed to the implant 11 so that the abutment 12 is fixed to the implant 11 by the locking element 13 , in other words, the locking element 13 The abutment 12 is penetrated through the abutment channel 1212 and is passed through the abutment passage opening 1213, and then the locking portion 113 is screwed by the self-locking opening 1131, thereby firmly locking the abutment 12 to the implant 11 . Incidentally, the locking member 13 is a screw.

As described above, the groove wall inclination angle AN1 is smaller than the abutment limit inclination angle AN2, and when the abutment 12 is coupled to the implant 11 to generate a misalignment error with the implant, the elastic fault-tolerant structure 1221 is elastically deformed. The deviation error is further reduced. Further, the misalignment error refers to the locking port 1131 and the abutment channel opening 1213 which should be completely matched with the alignment. Therefore, the position error range between the two is not fully aligned. .

Please refer to FIG. 7 and FIG. 8 together. FIG. 7 is an exploded cross-sectional view showing the dental implant assembly with the elastic fault-tolerant portion according to the first embodiment of the present invention; and the eighth embodiment shows the first embodiment of the present creation. The dental implant assembly having the elastic fault-tolerant portion has a three-dimensional exploded view of the crown. The dental implant assembly 1 with the elastic fault-tolerant portion provided by the present invention is used with a crown 3, and the crown 3 is disposed on The abutment 12 is more clearly illustrated. The abutment 12 further includes a crown setting portion 123, and the crown 3 is disposed on the crown setting portion 123, thereby forming a complete implant body.

Referring to FIG. 9A to FIG. 9C, FIG. 9A is a cross-sectional view showing a first state of the abutment channel having tolerances of the dental implant assembly having the elastic fault-tolerant portion according to the first embodiment of the present invention; Nine B diagram shows the dental implant component with the elastic fault-tolerant portion of the first embodiment of the present invention A second state cross-sectional view of the abutment channel having tolerances; and a ninth C diagram showing a third state cross-sectional view of the abutment channel having tolerances of the dental implant assembly having the elastic fault-tolerant portion of the first embodiment of the present invention . As shown in the figure, the dental implant assembly 1 having the elastic fault-tolerant portion provided by the first embodiment of the present invention causes the abutment channel 1212 to be skewed due to various factors during manufacture. That is, there is a skew angle between the abutment channel 1212 and the abutment axis A2, so that the abutment channel opening 1213 and the locking port 1131 do not completely match. That is to say, there is a misalignment error between the abutment channel opening 1213 and the locking port 1131, so that the locking component 13 will be stuck at the bottom of the limiting slot after passing through the abutment channel 1212 from the abutment channel opening 1213. 1112, and the self-locking and fixing port 1131 cannot be smoothly screwed into the locking portion 113.

However, by bending the elastic fault-tolerant structure 1221, the skew angle of the abutment channel 1212 can be smoothly reduced, and the abutment channel opening 1213 can be aligned with the locking port 1131, reducing the abutment channel opening 1213 and the locking port 1131. There is a bias error between them. Therefore, the locking member 13 smoothly enters the locking opening 1131 from the abutment passage opening 1213 and is smoothly screwed with the locking portion 113. In other words, since the abutment 12 has the elastic fault-tolerant structure 1221, when the angle at which the abutment 12 is placed in the implant 11 is adjusted, the elastic fault-tolerant structure 1221 is bent as the angle is adjusted, thereby reducing the abutment. A misalignment error between the passage opening 1213 and the locking port 1131.

In summary, after the dental implant assembly with the elastic fault-tolerant portion provided by the first embodiment of the present invention is used, the tolerance generated by the manufacturing process can be smoothly solved due to the tolerance generated during manufacturing. To the lowest, because the elastic fault-tolerant part can be used to adjust the angle when the abutment is implanted into the implant, thereby reducing the misalignment error between the abutment channel opening and the locking port, so that the locking component can be smoothly screwed into Locking part.

Please refer to FIG. 10A to FIG. 10C together. FIG. 10A is a schematic cross-sectional view showing the state of continuous crown implantation of the dental implant assembly with the elastic fault-tolerant portion according to the second embodiment of the present invention; Figure B is a partial cross-sectional view showing the first state of continuous crown implantation of the dental implant assembly having the elastic fault-tolerant portion of the second embodiment of the present invention; and the tenth C diagram showing the elasticity of the second embodiment of the present creation A partial cross-sectional view of the second state of the continuous crown implant of the dental implant component of the fault-tolerant portion. As shown, the second embodiment of the present invention is a dental implant assembly 1a having a resilient fault-tolerant portion. Among them, since the continuous crown 3a is fixed to the plurality of abutments 12a, and the continuous crown 3a is made of a steel material, the implantation angle of the abutment 12a is also fixed.

Therefore, in order to fit the plurality of abutments 12a, the implanter cannot adjust the angle at which the single abutment 12a is implanted into the implant 11a by bending the continuous crown 3a. In other words, the implanter cannot reduce the misalignment error between the one abutment opening 1213a and the one locking port 1131a by adjusting the angle at which the single abutment 12a is implanted into the implant 11a. Therefore, when a locking component 13a passes through the abutment channel 1212a and passes through the abutment channel opening 1213a, it will be stuck at the bottom of the limiting slot 1112a, and it is difficult to smoothly enter the locking port 1131a. The angle at which the abutment 12a is implanted into the implant 11a is an offset angle ANa between the implant axial direction A1a and the abutment axial direction A2a. If the angle of the implant 11a when implanting a alveolar bone 2a is deviated, the offset angle ANa may increase.

However, by pressing and bending a plurality of elastic fault-tolerant structures 1221a that abut against the limiting groove walls 1111a, the abutment passage opening 1213a can be brought closer to the locking opening 1131a. This reduces the influence of the misalignment error and the offset angle ANa when the locking member 13a is screwed with the locking portion 113a, so that the locking member 13a can be screwed into the locking portion 113a more easily. Specifically, when the elastic fault-tolerant structure 1221a abutting against the limiting groove wall 1111a is pressed and bent, the tapered limiting portion 121a can enter the tapered limiting groove 111a more deeply. That is, the abutment passage port 1213a is closer to the locking port. 1131a. As a result, the locking member 13a can be screwed into the locking portion 113a more easily from the locking opening 1131a.

In summary, the dental implant assembly with the elastic fault-tolerant portion provided by the second embodiment of the present invention successfully overcomes the problem that the cone-shaped limit cannot be adjusted by adjusting the deviation angle during the continuous crown implant operation. The position is able to enter the tapered limit groove deeper. The tooth implant assembly with the elastic fault-tolerant portion provided by the present invention, by pressing and bending the elastic fault-tolerant portion, allows the abutment to be more deeply disposed on the implant, thereby bringing the abutment passage opening closer to the locking port. Thereby, the locking element can be smoothly screwed into the locking portion.

With this creative description, it is known that this creation has the value of use in the industry. However, the above embodiments are merely illustrative of the two preferred embodiments of the present invention, and those skilled in the art can make various other modifications and changes as described in the above embodiments of the present invention. However, all of the improvements and variations made in accordance with the present embodiment are still within the scope of the creative spirit and definition of the present invention.
