Description

A jig apparatus for abutment alignment and an alignment fixing method of an abutment using the same

The present invention relates to a jig device for aligning an abutment and a method for fixing an abutment using the same, and more particularly, to a jig device for aligning an abutment with improved precision and a method for fixing an abutment using the same. it's about

In general, a denture or a prosthesis is an artificial periodontal tissue in the oral cavity that replaces a missing natural tooth and artificially restores the appearance and function. At this time, the dentures or prostheses can be installed inside the oral cavity to restore the masticatory function and prevent periodontal tissue deformation, and can be divided into partial/complete dentures and partial/complete prostheses according to the number of missing teeth.

On the other hand, the denture is installed by applying a dental adhesive to the inner surface-side mold groove is adhered to the surface of the gum. For this reason, there was a problem of causing a feeling of foreign body and pain due to direct occlusal pressure applied to the gums. On the other hand, the prosthesis is fixed to a fixture to be placed in the alveolar bone, thereby reducing the feeling of foreign body and pain in the gums due to occlusal pressure. However, since the prosthesis is substantially permanently fixed in the oral cavity, there is a problem in that it is difficult to manage. Accordingly, an overdenture that compensates for the shortcomings of the denture and the prosthesis has been disclosed.

In detail, while the overdenture is fixed to a fixture to be placed in the alveolar bone like the prosthesis, it is detachable from the oral cavity like the denture, so it is easy to manage such as cleaning. At this time, the overdenture includes a coupling means selectively coupled to the abutment fixed to the fixture.

At this time, the conventional coupling means is provided in a ball type that is individually matched to the fixture/abutment that is implanted and fixed to the pubic bone in plurality, or is a bar type that is fixed via a plurality of fixtures/abutments. provided

Here, the positional precision of the ball-shaped member coupled to the abutment is required due to the individual coupling to each fixture/abutment. For this reason, if any one of the plurality of ball-shaped members is not formed at the correct position, there is a problem that the overdenture cannot be installed accurately.

In addition, the bar-type coupling means is provided with a light-through inserting part so that a plurality of fixing bars passing through the fixtures/abutments are inserted, and it is easier to fasten than the ball-type coupling means. At this time, the fixing bar is provided with a rigid metal material and is bent corresponding to a predetermined bending angle so as to intersect the installation position of the fixture so as to pass through a plurality of fixtures/abutments previously placed in the target arch. .

At this time, the light oil insertion portion should be arranged open on both sides to correspond to the bent shape of the fixing bar. However, the abutment flows or rotates while the abutment is moved to the upper side of the fixture or the abutment disposed on the upper end of the fixture is rotationally fastened through a fastening screw. For this reason, there was a problem that the opening direction of the light oil insertion part did not coincide with the bending angle.

Moreover, when the fixing bar is forcibly inserted in a state where the light oil insertion part is not aligned, the restoring force of the bent state of the fixing bar is transmitted to the abutment and the fixture. Due to this, there is a serious problem that the alveolar bone in which the fixture is placed is melted or fractured.

1 is a cross-sectional view illustrating a process in which a digital overdenture is mounted on a fixing bar fixed to the holder abutment, and FIG. 2 is an exploded perspective view of the holder abutment for fixing the fixing bar.

1 to 2, the digital overdenture 60 is preferably understood as a dental restoration supported by a fixture installed in the alveolar bone like a conventional prosthesis while being detachably mounted in the oral cavity like a conventional denture. The digital overdenture 60 is mounted through a fixing bar 1430 disposed along the dental arch region, and the fixing bar 1430 is fixed to the oral cavity through a plurality of holder abutments 1410 .

In detail, a holder insertion part 65 is formed inside the digital overdenture 60 . At this time, one end of the clip 67 is embedded in the fixing hole 66 penetrating through the upper side of the holder inserting part 65, and as the resin filled in the fixing hole 66 is cured, the clip 67 is closed. It is fixed to the inside of the holder insertion part (65). Then, the holder abutment 1410 is fastened to the upper side of the implant 2 placed in the gum unit object 1 , and the fixing bar 1430 is fixed through the holder abutment 1410 . Here, when the fixing bar 1430 and the holder abutment 1410 are inserted into the holder inserting part 65, the clip 67 is fitted to the fixing bar 1430 and the digital over The denture 60 may be firmly mounted on the gum unit object 1 . Here, it is preferable to understand that the gum unit object 1 in FIG. 1 is an oral cavity.

In this case, the fixing bar 1430 is provided with both ends extending to a predetermined length and bent at a predetermined angle to correspond to the dental arch of the gum unit object 1 . As described above, as the range in which the fixing bar 1430 and the digital overdenture 60 engage with each other is formed as a whole along the dental arch, the state in which the digital overdenture 60 is mounted in the oral cavity is stably maintained. In addition, since the digital overdenture 60 is mounted on the gingival object 1 and prevents the gums, which are soft tissues, from flowing through the movement of the jaw during mastication or excessive pressure on the gums, discomfort during use can be minimized.

Here, the implant 2 and the holder abutment 1410 are implanted and fastened to a plurality of places to support the fixing bar 1430 as a whole. At this time, in the holder abutment 1410 , a fastening screw 1420 is inserted through a fastening hole 1413 penetrated in the central part, and the lower end of the fastening screw 1420 is screwed to the implant 2 and fixed. do. Then, the light oil inserting portion 1414 is depressed in the longitudinal direction at the upper end of the holder abutment 1410, and the fixing bar 1430 is inserted into the light oil inserting portion 1414. Here, it is preferable that the inner horizontal interval of the light oil insertion part 1414 corresponds to the diameter of the fixing bar 1430 or is set including a predetermined tolerance. And, as the pressure screw 1440 is fastened to the upper side of the light oil insertion unit 1414, the fixing bar 1430 is firmly fixed between the pressure screw 1440 and the inner end of the light oil insertion unit 1414. can be

In addition, a holder cover portion 1450 surrounding the outside of the upper end of the holder abutment 1410 in which the light oil insertion portion 1414 is formed may be further provided. Here, in the holder cover portion 1450, the communication insertion portion 1454, which is opened in the opposite direction to the light oil insertion portion 1414, is opened downward. Then, the fixing bar 1430 is inserted into the light oil insertion part 1414, the holder cover part 1450 is coupled to surround the upper end of the holder abutment 1410, and the pressure screw 1440 is the It is fastened to the holder abutment 1410 . Through this, as the pressure screw 1440 is fastened, an external force in the radial outward direction acts on the upper end of the holder abutment 1410, so that the upper end of the holder abutment 1410 is widened and the pressure screw ( 1440) can be prevented from being separated. At this time, since the fixing bar 1430 is exposed between the light oil insertion unit 1414 and the communication insertion unit 1454 , interference due to the holder cover unit 1450 can be prevented.

3 is an exemplary diagram illustrating a process of setting bending path information and implantation information applied to an embodiment of the present invention.

1 to 3 , the holder abutment 1410 should be aligned so that the direction in which the light oil insertion part 1414 is opened to both sides coincides with the direction in which the fixing bar 1430 is bent. To this end, the fixing bar 1430 is bent corresponding to the established bending path information (b), and the holder abutment 1410 is inserted through the light so that the bent fixing bar 1430 is inserted without interference. The portion 1414 is aligned corresponding to the bending path information (b).

In detail, in order to establish a plan for manufacturing the digital overdenture 60, a scanning image and a CT image for surface information and internal tissue information of the gingival unit object 1 are acquired. Then, the scanning image and the CT image are matched to generate a three-dimensional working image m1. And, the plurality of implants supporting the bending path information (b) of the fixing bar 1430 to which the clip 67 is fitted based on the three-dimensional work image (m1) and the fixing bar 1430 ( 2) and the placement information (A) of the holder abutment 1410 is established.

In this case, it is preferable that the fixing bar 1430 is provided in a state in which both ends are bent so as to extend to a predetermined length and to be disposed inside the dental arch region of the oral cavity. Here, the dental arch region is preferably understood as the upper end of the gum on which the digital overdenture 60 is covered.

In detail, both ends of the fixed bar 1430 have a predetermined bending angle (d) based on each bending point spaced apart at a predetermined interval so that the bent state of the fixing bar 1430 can be designed and determined based on an accurate reference. It is preferable to be bent and formed. Furthermore, it is preferable that the fixing bar 1430 is bent with respect to each of the bending points, so that the central portion and each of the opposite ends having different extension directions are formed in a straight line. That is, the fixing bar 1430 may be formed in a trapezoidal shape in which a wide side is opened as both sides of each of the bending points are bent to maintain a straight line while being disposed in the dental arch region.

To this end, the bending path information (b) includes a central line (B1) extending horizontally to the left and right on the anterior side, and a double-sided line (B2) designed to intersect the central line (B1) and a preset bending angle (d). includes Here, the central line B1 and each of the both side lines B2 correspond to the cross-sectional center of the virtual fixing bar m43 corresponding to the fixing bar 1430, and the central line B1 and each of the both side lines A portion that is spaced apart from (B2) inward by a radius of the virtual fixing bar m43 and intersects may be set as the bending point g.

Here, the bending point g is preferably set outside the radius of the virtual holder abutment m41 corresponding to the holder abutment 1410 . That is, the position of the bending point g may be determined first, and the anterior implantation point A1 may be set at a position in consideration of the radius of the virtual holder abutment m41. Alternatively, the anterior implantation point (A1) may be determined first and the position of the bending point (g) may be set.

As such, the interval between each of the bending points g and the bending angle d between the center line B1 and the both sides line B2 are accurately calculated and set in the design process of the digital overdenture 60 . Therefore, in the design process of the digital overdenture 60, not only the digital overdenture 60 but also the bending plan of the fixing bar 1430 and the implantation plan of the implant 2/holder abutment 1410 are performed simultaneously can be established Through this, the accuracy and precision of the digital overdenture 60 manufactured/prepared based on each established plan can be significantly improved when the oral cavity is mounted.

Here, the implantation information (A) may be set in plurality to pass through the bending path information (b), and the anterior implantation point (A1) is set to be spaced apart left and right as a pair to pass through the center line (B1). And the posterior implantation point (A2) can be set to pass through each of the both sides line (B2) one by one. Of course, the implantation information (A) is set first, and the bending path information (b) may be set to pass through the anterior implantation point (A1) and the posterior implantation point (A2).

4A and 4B are a plan view and a perspective view showing a fixing jig base among the abutment alignment jig apparatus according to an embodiment of the present invention, and FIG. 5 is an abutment alignment jig according to an embodiment of the present invention. It is a cross-sectional view showing a state in which the holder abutment is fitted in the fixing jig base of the device, and FIGS. 6a and 6b are the pivot guide jig base of the abutment alignment jig device according to an embodiment of the present invention. is a plan view and a perspective view showing And, Figure 7 is a flowchart showing a method for fixing the alignment of the holder abutment using the jig device for aligning the abutment according to an embodiment of the present invention, Figures 8a and 8c are It is an exemplary view showing a method of fixing the alignment of the holder abutment using a jig device for alignment of the abutment.

3 to 8c, the abutment alignment jig device according to the present invention includes a plurality of the holder abutments ( 1410) is preferably understood as a means for guiding the direction in which the gum unit is fastened to the object 1, that is, the opening direction of the light oil insertion unit 1414. This abutment alignment jig device includes a plurality of jig bases (10, 20) and an alignment coupling bar (30).

At this time, in the following, the gingival unit object (1) encompasses the impression model produced in response to the actual oral cavity and oral cavity, and the implant (2) is the fixture to be placed in the oral cavity and the analog to be placed in the impression model. It is preferable to understand it as encompassing. That is, the abutment alignment jig device is a means for temporarily aligning and fastening the holder abutment 1410 to the impression model in which the analog is implanted in order to check the bending state of the fixing bar 1430. can be used In addition, the abutment alignment jig device may be used as a means for aligning and fastening the holder abutment 1410 to the actual oral cavity in which the fixture is placed.

In detail, the jig bases 10 and 20 include body parts 11 and 21 and alignment heads 14 and 24 . Here, the body portions 11 and 21 have receiving grooves 12 and 22 into which the upper end of the holder abutment 1410 is inserted, and through-holes communicating with the receiving grooves 12 and 22 are formed therein. (13,23) is preferably penetrated upwards. Further, the alignment heads 14 and 24 extend outward in the horizontal direction from the upper edges of the body portions 11 and 21, and it is preferable that straight alignment grooves 15 and 25 crossing the upper surface are formed. At this time, although the shape of the alignment heads 14 and 24 is shown in the form of a rectangle with rounded corners in the drawings, the alignment heads 14 and 24 may be formed in various shapes such as a circle, an oval, and a hexagon.

These jig bases 10 and 20 may be arranged such that a pair of fixing jig bases 10 to be described later are adjacent to each other, or the fixing jig base 10 and a pivot guide jig base 20 to be described later are adjacent to each other. have. That is, the fact that the jig bases 10 and 20 are provided in plurality means that the fixing jig base 10 and the pivot guide jig base 20 are combined to be arranged in plurality, preferably in pairs. It is preferable to understand that

In addition, the alignment coupling bar 30 is provided in the form of a bar extending in the longitudinal direction, and a pair of adjacently arranged jig bases 10 and 20 are rotationally aligned to correspond to the bending path information (b). It is simultaneously inserted into the alignment grooves 15 that are communicated to be adjacent to each other in a straight line so as to be constrained. At this time, the cross-sectional diameter of the alignment coupling bar 30 is preferably formed to correspond to the inner spacing of the alignment groove (15). In addition, the alignment coupling bar 30 is preferably formed of a rigid material that minimizes deformation due to an external force transmitted through a fixing means such as a driver/drill inserted through the through-holes 13 and 23 . For example, the alignment coupling bar 30 may be provided as a linear fixed bar 1430 in a state before being bent according to the bending path information (b).

At this time, as long as the alignment coupling bar 30 is simultaneously inserted into the alignment grooves 15 and 25 formed on each upper surface of the pair of the jig bases 10 and 20, the alignment grooves 15 and 25 are formed in the center It may be aligned parallel to the line B1 or the both sides of the line B2. In addition, the holder abutment 1410 through the jig bases 10 and 20 guides fastening to the implant 2 in a state in which the holder abutment 1410 is also aligned in parallel with the center line B1 or the both sides line B2. can be

As such, in the present invention, since the jig bases 10 and 20 are individually coupled to the holder abutment 1410, the coupling tolerance between the holder abutment 1410 and the jig base 10 and 20 is It may be formed substantially close to zero. And, as the alignment coupling bar 30 is fitted into the adjacent alignment grooves 15 and 25, the individually coupled jig bases 10 and 20 are prevented from rotating or from being twisted in position. Therefore, the process of aligning and fastening the holder abutment 1410 to the gingival unit object 1 is performed to precisely correspond to the preset bending path information (b) and the implantation information (A), and the digital overdenture In the dental restoration process through (60), the accuracy can be significantly improved.

Here, it is preferable that the alignment grooves 15 and 25 are spaced apart from the inner diameter of the through holes 13 and 23 to the outside. Accordingly, the fixing means for fastening the fastening screw 1420 in a state in which the alignment coupling bar 30 is inserted into the alignment grooves 15 and 25 may be inserted into the through holes 13 and 23 . Accordingly, since the aligned state of the neighboring jig bases 10 and 20 is restrained through the alignment coupling bar 30, rotation by rotation is limited. Through this, it is possible to prevent the jig bases 10 and 20 from rotating together with the fixing means due to the rotational force of the fixing means. Accordingly, since the rotational force of the fixing means is substantially transmitted to the fastening screw 1420 , the holder abutment 1410 can be firmly fastened to the upper end of the implant 2 .

Meanwhile, the jig bases 10 and 20 preferably include the fixing jig base 10 and the pivot guide jig base 20 .

In detail, the fixing jig base 10 has an alignment protrusion 12a fitted to the light oil insertion part 1414 formed at the upper end of the holder abutment 1410 protruding from the inner periphery of the receiving groove 12 . provided in the form. Through this, the fixing jig base 10 aligns the arrangement direction of the holder abutment 1410 in a state coupled to the upper end of the holder abutment 1410 and fastens the fastening screws 1420 . Acts as a direct guide.

That is, when the fixing jig base 10 is coupled to the upper end of the holder abutment 1410 , the alignment protrusion 12a is coupled to the light oil insertion portion 1414 . Accordingly, when the fixing jig base 10 is rotated around the holder abutment 1410, the holder abutment 1410 may be rotated in conjunction with each other. At this time, so that the holder abutment 1410 is rotated and aligned with the fixing jig base 10 in response to the bending path information (b), the alignment protrusion (12a) is the through hole (13). It is preferable to protrude parallel to the alignment groove 15 on both sides.

In detail, the fixing jig base 10 is coupled to each upper end of the holder abutment 1410 disposed to correspond to the anterior implantation point A1, and the upper surface of each fixing jig base 10 is The fixing jig base 10 is rotated so that the alignment groove 15 formed in the part communicates in a straight line. At this time, the alignment projection (12a) is parallel to the alignment groove (15), but when the upper end of the holder abutment 1410 is fitted into the receiving groove (12), the alignment projection (12a) is the light oil insertion portion (1414). Therefore, when a pair of the fixing jig base 10 is arranged such that the alignment grooves 15 formed on the upper surfaces of each of them communicate in a straight line, the light oil insertion part 1414 in which the alignment protrusions 12a are fitted. Both opening directions may be aligned parallel to the center line B1 of the bending path information (b).

At this time, the rotating state of the fixing jig base 10 may be constrained as the alignment coupling bar 30 is simultaneously inserted into the adjacent alignment groove 15 . Here, the alignment coupling bar 30 is formed to have a cross-sectional diameter corresponding to the inner interval of the alignment groove 15, and at the same time as a pair of adjacent fixing jig bases 10. It is formed with a length exceeding the overall distance between both sides. This is preferable. Through this, when the alignment coupling bar 30 is inserted into each alignment groove 15 of the pair of the fixing jig base 10, each of the alignment grooves 15 is parallel to the center line B1. Rotation may be constrained.

In addition, as the alignment coupling bar 30 is inserted to be engaged with the pair of the fixing jig base 10 at the same time, it not only restricts the rotation of the aligned holder abutment 1410 but also the fixing jig base ( 10) It can function as a stopper that restricts the rotation of the liver. Therefore, even if the fixing means inserted through each of the through-holes 13 is rotated in a state in which the fixing jig base 10 is rotationally restricted, it is possible to prevent the fixing jig base 10 from interlocking.

As such, in the present invention, the fixing jig base 10 is individually coupled to each of the holder abutments 1410 , and may be mutually supported as a stopper through the alignment coupling bar 30 . Through this, the state in which the light oil inserting part 1414 is arranged parallel to the center line B1 can be accurately maintained, and the light oil inserting part 1414 of the holder abutment 1410 is the bending path information. It can be fastened and fixed to the anterior side in a state in which it is accurately arranged in correspondence with (b).

On the other hand, the jig base 20 for the pivot guide is supported by the holder abutment 1410 and the receiving groove 22 is recessed in a circular cross-sectional shape so as to be freely rotated. Through this, the pivot guide jig base 20 is coupled to the holder abutment 1410 first fixed through the fixing jig base 10 on the anterior side. Then, the holder abutment 1410 fixed to the anterior side is rotated as a rotation center.

At this time, since the pivot guide jig base 20 has no elements constraining or interfering in the circumferential direction of the receiving groove 22 , it is fixed to the anterior side even though it is coupled to the upper end of the holder abutment 1410 and rotated. The holder abutment 1410 is not interlocked. Therefore, even if the alignment grooves 15 and 25 formed on the upper surfaces of the fixing jig base 10 and the pivot guide jig base 20 are rotated to communicate in a straight line, the fixing jig base 10 is The coupled holder abutment 1410 is rotated interlockingly, but the holder abutment 1410 coupled to the jig base 20 for the pivot guide is not rotated. Through this, even if the pivot guide jig base 20 is rotated to guide and constrain the rotated state of the fixing jig base 10, the holder abutment 1410 coupled to the pivot guide jig base 20 ) can be prevented from being arbitrarily re-rotated while aligned and fastened to the implant (2).

On the other hand, the fixing jig base 10 has a first interval w1 in which the interval between the center point of the receiving groove 12 and the inner edge of the alignment groove 15 exceeds the radius value of the through hole 13 . It is preferable to be formed to correspond to. In this case, it is preferable that the through hole 13 and the inner edge of the alignment groove 15 be spaced apart from each other by a minimum distance that allows the through hole 13 and the alignment groove 15 to be partitioned.

And, in the pivot guide jig base 20, the vertical spacing w0 between the center point of the receiving groove 22 and the inner edge of the alignment groove 25 is calculated and set by the following Equation 1 This is preferable. In this case, the vertical spacing w0 is preferably set according to the bending path information (b) and the bending angle (d).

Here, w0 is the vertical spacing between the center point of the receiving groove 22 of the pivot guide jig base 20 and the inner edge of the alignment groove 25, w1 is the fixing jig base 10 of the The first interval w1, L between the center point of the through hole 13 and the inner edge of the alignment groove 15 is a virtual line connecting the anterior implantation point A1 and the posterior implantation point A2 with a straight line The length L, θ is preferably understood as an angle θ between the both sides of the line B2 and the virtual line.

In addition, in the pivot guide jig base 20, the distance w0 between the center point of the through hole 23 and the inner edge of the alignment groove 25 is the cross-sectional diameter of the fixing bar 1430 and the holder abutment. It is preferable to set in excess of the interval including the radius of the upper end of the ment (1410). That is, it is preferable that the bent portion of the fixing bar 1430 is set to be spaced apart from the outside of the holder abutment 1410 to be implanted on the anterior side.

In detail, each bending point g of the fixing bar 1430 is set in consideration of the dental arch region, the radius of the upper end of the holder abutment 1410 and the cross-sectional diameter of the fixing bar 1430 . This means that the fixing bar 1430 bent in response to the bending path information (b) is fastened and fixed according to the implantation information (A). This is to prevent the bent portion of the fixing bar 1430 from interfering with the light oil insertion portion 1414 of the holder abutment 1410 when simultaneously inserted. Therefore, each bent portion of the fixing bar 1430 should be spaced outwardly from each light oil insertion portion 1414 of the holder abutment 1410 fastened to the anterior side. To this end, the anterior implantation point (A1) is the midline of the oral cavity at an interval exceeding the sum of the radius of the upper end of the holder abutment 1410 and the cross-sectional diameter of the fixing bar 1430 from the bending point (g). set apart to the side.

Accordingly, the both sides of the line (B2) do not coincide with the virtual line connecting the anterior implantation point (A1) and the posterior implantation point (A2) adjacent to each other. That is, the both sides of the line (B2) may be set as a virtual line connecting the bending point (g) and the posterior implantation point (A2) spaced apart to the outside of the anterior implantation point (A1). Therefore, in the pivot guide jig base 20, the interval w0 between the center point of the through hole 23 and the inner edge of the alignment groove 25 is the center line B1 and the both sides line B2. It is preferable that it is set in consideration of the state arranged at the predetermined bending angle d.

In addition, the bending point g is moved from the anterior insertion point A1 to the holder so that the bent portion of the fixing bar 1430 does not interfere with the holder abutment 1410 fastened and fixed to the anterior side. It is preferable to be formed at a position exceeding the sum of the radius of the upper end of the abutment 1410 and the cross-sectional diameter of the fixing bar 1430 . To this end, in the pivot guide jig base 20, the spacing w0 is preferably set to a value calculated by Equation 1 above.

Through this, the pivot guide jig base 20 is coupled to the upper end of the holder abutment 1410 fastened to the anterior side, and the fixing jig base 10 is disposed on the posterior side. When it is coupled to the upper end of the abutment 1410 and rotated, the alignment grooves 15 and 25 of the jig base 20 for the pivot guide and the jig base 10 for fixing are parallel to the both sides line B2. However, it may be arranged to communicate in a straight line. And, when the alignment coupling bar 30 is coupled to the adjacent alignment grooves 15 and 25, the holder abutment 1410 to which the fixing jig base 10 is coupled is the light oil insertion part 1414. may be fastened and fixed through the fixing means in a state aligned parallel to the both sides of the line (B2).

In addition, the fixing jig base 10 and the pivot guide jig base 20 have a maximum interval between both ends of the alignment heads 14 and 24 adjacent to the gum unit object 1 and are fastened and fixed. It is preferable that the holder abutment 1410 be formed to be less than the interval between the respective implantation points A1 and A2. Therefore, the jig base 10 and the pivot guide jig base 20 for fixing to a pair of the anterior implantation point (A1) or the neighboring anterior implantation point (A1) and the posterior implantation point (A2) ), it is possible to prevent interference while overlapping the alignment heads 14 and 24 with each other even if they are disposed.

On the other hand, referring to FIGS. 7 to 8C , the alignment and fixing method of the holder abutment using the abutment alignment jig device establishes the bending path information (b) and the placement information (A) (s10) , Aligning and fixing a pair of the holder abutment 1410 on the anterior side using a pair of the fixing jig base 10 (s20), and the fixing jig base 10 and the pivot guide jig and a series of steps of aligning and fixing the holder abutment 1410 to the posterior side using the base 20 (s30). Hereinafter, the implantation of the holder abutment 1410 in the oral cavity will be described as an example, and it is preferable to understand that the gingival object 1 is the oral cavity and the implant 2 is a fixture.

In detail, the implantation information (A) and the bending path information (b) are established, and the implant (2) in the gum unit (1) is placed at each of the implantation points (A1, A2) of the implantation information (A). Correspondingly installed. Then, a pair of the holder abutment 1410 is disposed on the gum unit object 1 in correspondence with the anterior implantation point A1. At this time, hereinafter the holder abutment 1410 is disposed on the gum-related object 1 means that the holder abutment 1410 is placed on each upper end of the implant 2 placed in the gum-related object 1 . ) is preferably understood as being individually arranged. Here, the holder abutment 1410 is disposed in each of the implants 2 in a state in which the fastening screws (1420 in FIG. 2) are inserted therein, preferably at the upper end of the implant 2 The fastening screw ( 1420 of FIG. 2 ) may be arranged in a loosely pre-fastened state with 2-3 turns left.

In this case, the fixing bar 1430 may be prepared in a bent state corresponding to the bending path information (b) based on each of the bending points (g). Here, each bent portion of the fixing bar 1430 may be bent by being supported by a bending device having a narrow tip so that the bending rate is minimized. Through this, a gap that interferes with the light oil insertion portion 1414 of the holder abutment 1410 is minimized, and the restoring force can be minimized in a state in which the fixing bar 1430 is bent.

And, a pair of the fixing jig base 10 is coupled to each upper end of the pair of holder abutments 1410 pre-fastened to the anterior side. At this time, the alignment protrusion (12a) protruding from the inner periphery of the receiving groove (12) of each of the fixing jig base (10) is engaged with the light oil insertion part (1414) of the holder abutment (1410). Here, the alignment protrusions 12a are formed in parallel with the alignment grooves 15 formed on the upper surface of each of the fixing jig bases 10 . Accordingly, when the fixing jig base 10 is coupled to the upper end of the holder abutment 1410 , the alignment groove 15 may be aligned parallel to the light oil insertion portion 1414 .

Here, each of the fixing jig base 10 is rotated so that the adjacent alignment groove 15 communicates in a straight line, and the holder abutment 1410 is rotated together with each of the fixing jig base 10 . can And, when the alignment coupling bar 30 is simultaneously inserted into the adjacent alignment groove 15, the rotation of the pair of fixing jig bases 10 is restricted at the same time. Through this, each light oil insertion portion 1414 of the pair of holder abutment 1410 disposed on the anterior side may be aligned parallel to the center line B1.

Then, the fixing means is inserted through the through hole 13 formed in each of the fixing jig base 10, and the fastening screw (1420 in FIG. 2) pre-fastened therein is completely rotated to the implant (2). As it is fastened, the holder abutment 1410 may be fastened to the anterior side. At this time, rotation of the fixing jig base 10 is restricted through the alignment coupling bar 30 , and the holder abutment 1410 is fitted to the alignment protrusion 12a so that rotation is restricted. Accordingly, rotational force may be transmitted only to the fastening screw ( 1420 in FIG. 2 ) in a state in which the fixing means is rotationally supported by the through hole 13 . Accordingly, the state in which the light oil insertion part 1414 is parallel to the center line B1 can be restrained, and the anterior implantation point A1 and the pair of the holder abutment 1410 are preset. Corresponding to the center line (B1) can be fixed in an accurate position and direction.

At this time, the holder abutment 1410 is aligned and fastened to the anterior side by using a straight fixing bar that is not bent to the holder abutment 1410 on the anterior side from which the fixing jig base 10 is separated. You can check the fixed status. That is, if the linear fixing bar does not interfere at the same time inserting the adjacent light oil insertion unit 1414, it can be determined that it is correctly aligned and fastened.

On the other hand, the fixing jig base 10 is separated from the holder abutment 1410 fixed to the anterior side. In addition, the pivot guide jig base 20 is alternately coupled to the holder abutment 1410 fixed to one side of the anterior side. In addition, the holder abutment 1410 is disposed and the fixing jig base 10 is coupled to the upper end corresponding to one side of the posterior implantation point A2. That is, based on the midline of the oral cavity, the pivot guide jig base 20 and the holder abutment 1410 fastened to one anterior side and the holder abutment 1410 pre-fastened to one posterior side, respectively. The fixing jig base 10 is coupled.

Then, each jig base rotates so that the alignment groove 25 formed on the upper surface of the pivot guide jig base 20 and the alignment groove 15 formed on the upper surface of the fixing jig base 10 communicate in a straight line. do. At this time, in the pivot guide jig base 20, since the receiving groove 22 is recessed in a circular shape, the direction in which the holder abutment 1410 fastened to the anterior side is fastened is maintained. That is, the pivot guide jig base 20 may be freely rotated around the holder abutment 1410 fastened to the anterior side. On the other hand, in the fixing jig base 10, since the alignment protrusion 12a protrudes from the receiving groove 12, the holder abutment 1410 pre-fastened to one side of the molar side is the fixing jig base. (10) and interlocking rotation.

In addition, when the fixing jig base 10 and the alignment grooves 15 and 25 formed on each upper surface of the pivot guide jig base 20 are rotatably arranged to communicate in a straight line, the fixing jig base 10 is The holder abutment 1410 of the coupled posterior side may be rotationally aligned in parallel to the both sides of the line B2. Then, the alignment coupling bar 30 is inserted into the adjacent alignment groove 15, the fixing means is inserted through the through hole 13 formed in the fixing jig base 10, and the fastening screw ( As 1420 of FIG. 2 is rotated and fastened, the holder abutment 1410 may be fastened and fixed to correspond to the posterior implantation point A2.

At this time, the posterior implantation point (A2) is set to the left and right based on the midline. Accordingly, the holder abutment 1410 can be fastened to the other molar side by using the fixing jig base 10 and the pivot guide jig base 20 in the above-described manner.

As such, in the present invention, even if the jig bases 10 and 20 are individually prepared corresponding to the holder abutment 1410, the center line B1 and the both sides line B2 through the alignment coupling bar 30 can be aligned to be exactly parallel to each other. Therefore, the conventional alignment holder precisely manufactures a plurality of receiving grooves in one body in response to the implantation information (A) and the bending path information (b), thereby solving the problem that the manufacturing difficulty is increased and the manufacturing process is increased. can do. In addition, the holder abutment 1410 is the bending path information (b) due to the overlapping of the error occurring during the manufacturing of the conventional alignment holder formed of a single body and the error in the implantation process of the implant (2). It is possible to prevent in advance the problem of not being able to fasten correctly in response to this.

Moreover, on the anterior side, the alignment grooves 15 of the pair of fixing jig bases 10 can be aligned in parallel with the central line B1 by simply arranging them to communicate in a straight line. In addition, the posterior side is aligned in parallel with the both sides line (B2) as long as the alignment grooves 15 and 25 of the fixing jig base 10 and the pivot guide jig base 20 are arranged to communicate in a straight line. can As such, the present invention has a low level of operation difficulty for aligning the light oil insertion part 1414 of the holder abutment 1410, and the aligned state corresponds to the preset placement information (A) and the bending path information (b). It can be formed precisely and precisely.

In addition, the fixing jig base 10 can be standardized to correspond to the diameter of the upper end of the holder abutment 1410 and can be prepared for general use, and the interval between the bending angle d and each of the bending points g If this is standardized, the jig base 20 for the pivot guide may also be prepared for general use. Through this, since the hassle of separately designing and manufacturing the jig bases 10 and 20 for each patient is minimized, the overall process and time of dental restoration can be shortened, and costs can be reduced.

Of course, in some cases, when the gingival unit object 1 is provided as an impression model and the implant 2 is analog, the holder abutment 1410 is accurately fastened and fixed through the above process. The bending angle d of the bar 1430 can be confirmed. That is, if there is a portion that cannot be accurately inserted among the plurality of holder abutments 1410 while inserting the bent fixing bar 1430 into the light oil insertion part 1414, the bending angle d of the fixing bar 1430 ) can be adjusted so that it matches accurately. And, when the bending of the fixing bar 1430 is finished, the holder abutment 1410 may be moved to the oral cavity through the separate holder jig to be fastened and fixed.
