Description

Alignment fixing method for holder abutment using jig apparatus

The present invention relates to a method for fixing alignment of a holder abutment using a jig device, and more particularly, to a method for fixing alignment of a holder abutment using a jig device having improved precision.

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 denture or prosthesis may be installed inside the oral cavity to restore the masticatory function and prevent the deformation of the periodontal tissue. These dentures or prostheses may be classified into partial/complete dentures or 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. As a result, there is a problem in that a feeling of foreign body and pain are caused by direct occlusal pressure applied to the gums. On the other hand, the prosthesis is fixed to the implant to be placed in the alveolar bone to reduce the feeling of foreign body and pain of the gums due to the 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 which is a dental restoration that compensates for the shortcomings of the denture and the prosthesis has been disclosed.

In detail, while the overdenture is fixed to the implant 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. In this case, the overdenture includes a coupling means selectively coupled to the abutment fixed to the implant.

Here, the conventional coupling means is provided in a ball type that is individually matched to implants/attachments placed and fixed in plurality in the alveolar bone, or is provided in a bar type fixed via a plurality of implants/abutments.

On the other hand, the bar-type coupling means includes an abutment each coupled to a plurality of implants and a fixing bar coupled via a plurality of the abutments. At this time, the fixing bar is provided with a rigid metal material, both ends are bent at a predetermined angle, and the abutment is formed with a light oil insert into which the fixing bar is inserted and fixed.

Here, the light insertion part should be aligned so that the opening direction corresponds to the bending angle of the fixing bar. However, in the process of moving the abutment to the upper side of the implant or the abutment disposed on the upper end of the implant is rotationally fastened through a fastening screw, the abutment flows or is further rotated. For this reason, there was a problem that the opening direction of the light oil insertion part did not coincide with the bending angle of the fixing bar.

In addition, when the fixing bar is forcibly inserted into the light oil insertion part in which the opening direction is not accurately aligned, restoring force for maintaining the bent state of the fixing bar is transmitted to the abutment and the implant. Due to this, there is a serious problem in that the alveolar bone in which the implant is placed is melted or fractured.

On the other hand, anesthesia is performed for the safety of the patient in the dental restoration process of placing the implant and fixing the abutment and the fixing bar. At this time, the normal anesthesia maintenance time is limited to about 4 hours, and the above process should be performed within the limited time. In addition, an auxiliary device for guiding the alveolar bone drilling, the implant placement, and the fastening of the abutment is used in the dental restoration process, and a gap is minimized between the parts coupled to each other for precision between the auxiliary devices.

However, there is a problem in that it is difficult to handle the implant and the abutment in the correct direction due to the interference fit while minimizing the gap between the auxiliary devices. That is, there is a problem in that the time required for handling between each auxiliary device is excessively delayed, and the overall dental restoration process cannot be performed for a limited time. This can cause serious problems in that the patient wakes up from anesthesia before the dental restoration process is complete. In addition, there is a problem in that precision is lowered due to the hasty progress of each step of the dental restoration process.

Through the above solutions, the present invention provides the following effects.

First, as the surgical guide is separated from the oral cavity after implant placement is complete, in order to align the coupling direction of the holder abutment to which the fixing bar is fixed, the interference element is generated when rotating the jig device that is individually coupled to the upper end of the holder abutment. Since the degree of freedom of direction adjustment is improved by being removed, the procedure can be performed quickly within the anesthesia maintenance time.

Second, the problem that the jig device is supported on the inner circumferential surface of the guide hole formed in the surgical guide and rotates stiffly due to frictional force is fundamentally eliminated, so that the holder abutment rotates freely interlocking with the jig device, and the opening direction of the diesel insertion part is the fixed bar Since it is precisely aligned corresponding to the bent extension direction, precision can be significantly improved.

Third, the jig device is provided to be individually coupled to each holder abutment, so that the coupling position tolerance between the jig device and the holder abutment is formed substantially close to zero, and the alignment direction of the jig device provided to be spaced apart from each other is the alignment coupling bar. Since the fastening of the fastening screw is guided in a state constrained in parallel with the preset bending path information, the coupling accuracy can be significantly improved.

Fourth, the alignment protrusion formed in the jig device is inserted into the light oil insertion unit, and the alignment coupling bar provided in the shape of a bending bar in which both ends are bent in consideration of the bending path information is simultaneously inserted into the alignment groove formed parallel to the alignment projection, the light oil insertion unit Since the opening direction is precisely aligned, operation precision can be significantly improved.

Here, the holder abutment 1410 is fastened to the upper end of the implant through the fastening screw 1420, and the fastening screw 1420 leaves 2 to 3 rotations and is not fully tightened. It is preferred to place

Meanwhile, it is preferable that the fixing jig base 10 is coupled to the holder abutment 1410 on the upper side of the holder abutment 1410 . And, when the alignment coupling bar 19 is inserted into the alignment groove 15 formed on the upper surface of the fixing jig base 10 in a state in which the fixing jig base 10 is rotated, the fixing jig base 10 ( 10) rotation can be constrained.

At this time, the alignment groove 15 is disposed parallel to the light oil insertion portion 1414 formed on the upper side of the holder abutment (1410). Therefore, when the rotation of the fixing jig base 10 is restricted through the alignment coupling bar 19, the light oil insertion part 1414 formed in the holder abutment 1410 is inserted into the bending path information (B). can be sorted correspondingly. In addition, the holder abutment 1410 may be fastened to the implant in a state in which the light oil insertion part 1414 is aligned. Here, it is preferable to understand that the fastening is not unnecessarily rotated as the fastening screw 1420 is completely tightened to the top of the implant.

In detail, the fixing jig base 10 preferably includes a body 11 and an alignment head 14 . Here, a receiving groove 12 into which the upper end of the holder abutment 1410 is inserted is formed in the body 11, and a through hole 13 communicating with the receiving groove 12 penetrates upward. It is preferable to be In addition, the alignment head 14 is formed to extend outwardly in the horizontal direction from the upper edge of the body portion 11, and includes a straight alignment groove 15 that crosses the upper surface of the alignment head 14.

At this time, so that the holder abutment 1410 is rotated in conjunction with the fixing jig base 10, the fixing jig base 10 has an alignment protrusion 12a that is fitted to the light oil insertion part 1414. It is preferable to be provided in a protruding form on the inner periphery of the receiving groove 12 .

In detail, the alignment protrusion (12a) is preferably arranged parallel to the alignment groove (15). Accordingly, when the fixing jig base 10 is coupled to the upper end of the holder abutment 1410 , the alignment protrusion 12a may be fitted inside the upper end of the light oil inserting portion 1414 . And, when the fixing jig base 10 is rotated, the holder abutment 1410 may be rotated in communication with the fixing jig base 10 .

On the other hand, it is preferable that the alignment coupling bar 19 is bent corresponding to the bending path information (B). And, it is preferable that the alignment coupling bar 19 is simultaneously inserted into the alignment grooves 15 formed in the plurality of fixing jig bases 10 . Through this, the alignment grooves 15 formed in the fixing jig base 10 may be aligned in a direction corresponding to the constraint bending information K to be described later.

In detail, the constrained bending information (K) is preferably understood as a virtual line set apart from the bending path information (B) by a preset offset interval (k3). At this time, it is preferable that the preset offset interval k3 is set as a distance between the center of the through hole 13 formed in the fixing jig base 10 and the longitudinal center line of the alignment groove 15 . In addition, the constraint bending information (K) is preferably set to be spaced apart in the horizontal direction on the labial or lingual side of the oral cavity based on the bending path information (B), and more preferably, it may be set apart from the labial side of the oral cavity.

At this time, the constraint bending information (K) is set to correspond to the bending path information (B), and the alignment groove (15) is formed to correspond to the alignment protrusion (12a). Accordingly, when the fixing jig base 10 is rotated and constrained through the alignment coupling bar 19 , the alignment groove 15 is arranged to correspond to the constraint bending information K. At this time, the holder abutment 1410 is rotated interlockingly with the fixing jig base 10 as the alignment protrusion 12a is inserted into the light oil insertion part 1414, and through the alignment coupling bar 19 The direction of rotation may be constrained. Through this, the opening direction of the via insertion part 1414 can be precisely aligned to correspond to the extension direction of the bending path information (B).

Here, the alignment coupling bar 19 is preferably provided with both ends bent based on the constraint bending information (K). In detail, the constraint bending information K corresponds to the offset interval k3 from the constraint center line k1 spaced apart from the center line B1 in correspondence to the offset interval k3 and the both sides line B2. It is preferable to include a spaced apart constraint both sides line (k2). At this time, the constraint bending information (K) may be set such that the both sides of the constraint line (k2) are bent at the constraint center line (k1) and a preset constraint bending angle. Furthermore, the constrained bending information (K) may be set to the same angle as the bending angle (d) of the bending path information (B).

In addition, each constraint bending point g2 of the constrained bending information K may be set in consideration of the offset interval k3 for each bending point g1 of the bending path information B. That is, in the constrained bending information (K), the interval between the pair of constrained bending points (g2) may be set to be greater than the interval between the bending points (g1) of the bending path information (B). Accordingly, the angle between the central portion and each of both end portions of the alignment coupling bar 19 may correspond to the bending angle d. Therefore, as long as the alignment coupling bar 19 is inserted into the alignment groove 15 , the via insertion part 1414 may be aligned and constrained in a direction corresponding to the bending path information B.

At this time, as the alignment coupling bar 19 is simultaneously coupled to the plurality of fixing jig bases 10 , each of the fixing jig base 10 and the fixing jig base 10 are coupled to the holder abutment Rotation of the ment 1410 is limited as a whole. Then, a fixing means for fastening the fastening screw 1420 is inserted through the through hole 13 formed in the fixing jig base 10 . Then, when the fastening screw 1420 is completely fastened to the upper end of the implant by manipulating the fixing means, the holder abutment 1410 may be firmly fastened and fixed.

Here, rotation of each of the holder abutments 1410 is restricted through the fixing jig base 10 to which the alignment coupling bar 19 is coupled. Therefore, even if the fixing means is operated to rotate, the state in which the light oil inserting unit 1414 is arranged corresponding to the bending path information (B) can be stably maintained.

As such, in the present invention, after the surgical guide is separated from the restoration target arch, the holder abutment 1410 is individually disposed on the upper side of the implant. And, the fixing jig base 10 is coupled to the upper end of the holder abutment (1410). Therefore, in the fixing jig base 10, the outer surface of the body 11 is a separate dental restoration auxiliary means (for example, in addition to the insertion of the alignment coupling bar 19 into the alignment groove 15) The problem of interference or restraint by the surgical guide) can be fundamentally solved. In addition, since the coupling position tolerance between the holder abutment 1410 and the fixing jig base 10 may be formed substantially close to zero, the holder abutment 1410 through the fixing jig base 10 . ) can be precisely guided in the fastening direction.

Through this, since the fixing jig base 10 and the holder abutment 1410 are simultaneously freely rotated around the implant, the degree of freedom of direction adjustment can be significantly improved. Therefore, the direction of the holder abutment 1410 can be quickly adjusted, so that, within a time period during which the anesthetic treatment effect performed during dental restoration is maintained, from the placement of the implant to the fastening and fixing of the holder abutment 1410 quickly can proceed.

At this time, as long as the fixing jig base 10 is constrained through the alignment coupling bar 19 , the light oil insertion part 1414 is aligned in the correct direction through the constrained fixing jig base 10 . The fastening screw 1420 may be completely fastened in the . Here, the fixing jig base 10 is individually matched to each of the holder abutments 1410 , and the diameter of the receiving groove 12 is standardized according to the holder abutment 1410 and manufactured for general purpose. . Accordingly, the hassle of individually manufacturing a jig means for guiding the alignment and fastening of the holder abutment 1410 for each patient can be eliminated. In addition, the overall cost of dental restoration can be significantly reduced by using the jig device of the aspect.

On the other hand, the jig device is separated from the holder abutment 1410 fastened to the implant. Then, the fixing bar 1430 is inserted into the light oil insertion part 1414 formed in each of the holder abutments 1410, and the fixing bar 1430 is pressed and fixed through the pressing screw 1440. . Here, as the alignment coupling bar 19 is coupled to the alignment groove 15 , the via insertion part 1414 is precisely aligned in response to the bending path information (B). And, the fixing bar 1430 is prepared for bending in response to the bending path information (B).

Therefore, the fixing bar 1430 can be easily inserted without interfering when inserted into the via insertion part 1414. In addition, since the bending angle of the fixing bar 1430 and the opening direction of the light oil insertion part 1414 are different, the fixing bar 1430 is forcibly fitted into the holder abutment 1410 and the fixing bar 1430 ) can be prevented from being transmitted. Therefore, since the serious problem of melting or fracture of the alveolar bone in which the implant is placed is prevented in advance, safety can be significantly improved.

Therefore, it is preferable to understand that the anterior holder abutment 1410 to be described later is the holder abutment 1410 fastened to the implant placed on the anterior side.

In addition, it is preferable to understand that the holder abutment 1410 is arranged or fastened to the posterior side to be arranged or fastened to the implant in which the holder abutment 1410 is placed on the posterior side. Therefore, it is preferable to understand that the posterior holder abutment 1410 to be described later is a holder abutment 1410 fastened to the implant placed on the posterior side.

Referring to FIG. 9A , a pair of the holder abutment 1410 may be disposed on the implant placed corresponding to the anterior implantation point A1 . In addition, the fixing jig base 10 may be coupled to the upper end of the pair of holder abutments 1410 disposed on the anterior side, respectively. And, the fixing jig base 10 is rotated so that the alignment grooves 15 respectively formed in the fixing jig base 10 are arranged in a straight line. Then, when the alignment coupling bar 19 is inserted into the alignment groove 15 arranged in a straight line, the pair of the holder abutment 1410 arranged on the anterior side is the center line ( The rotation may be constrained in a state arranged in a direction corresponding to B1).

Then, a pair of the holder abutment 1410 supported by the fixing jig base 10 and aligned so that the light oil insertion part 1414 is continuously opened to the left and right is fastened to the implant already placed on the anterior side. can be fixed.

Meanwhile, referring to FIG. 9B , the pivot guide jig base 20 is alternately coupled to one of the pair of holder abutments 1410 fixed to the anterior side. At this time, it is preferable to understand that the replacement coupling means separating the fixing jig base 10 from the upper end of the holder abutment 1410 and coupling the pivot guide jig base 20 .

In detail, the jig base 20 for the pivot guide is preferably recessed in a circular cross-sectional shape of the receiving groove 22 formed in the body portion 21 . Therefore, when the jig base 20 for the pivot guide is coupled to the upper part of the holder abutment 1410, only the jig base 20 for the pivot guide is free while the holder abutment 1410 is fixed. can be rotated.

Here, the posterior holder abutment 1410 may be aligned and fastened to correspond to the bending path information B through the fixing jig base 10 and the pivot guide jig base 20 . .

In detail, the holder abutment 1410 may be disposed on the implant placed corresponding to the posterior implantation point A2. In this case, the fixing jig base 10 may be coupled to the upper end of the holder abutment 1410 disposed on the molar side. Here, the alignment coupling bar 19A to the fixing jig base 10 and the pivot guide jig base 20 coupled to each of the holder abutments 1410 provided adjacent to the anterior and posterior sides. can be combined simultaneously.

In detail, the alignment groove 15 formed in the fixing jig base 10 and the alignment groove 25 formed in the pivot guide jig base 20 may be rotated to communicate in a straight line. At this time, since the fixing jig base 10 includes the alignment protrusion 12a, when the fixing jig base 10 is rotated, the posterior holder abutment 1410 may be rotated in conjunction.

In addition, the jig base 20 for the pivot guide may be freely rotated while being supported by the anterior holder abutment 1410 because the receiving groove 22 has a circular cross-sectional shape. Therefore, the problem that the holder abutment 1410 fastened to the anterior side in a preferred direction through the fixing jig base 10 is arbitrarily interlocked and rotated when the pivot guide jig base 20 is rotated is fundamental. can be prevented with

On the other hand, each of the alignment grooves 15 and 25 of the fixing jig base 10 and the pivot guide jig base 20 are rotated to communicate in a straight line, and the alignment coupling bar 19A is each of the alignment grooves (15,25) is inserted at the same time. Through this, the rotation of the fixing jig base 10 and the pivot guide jig base 20 is restricted, and the posterior holder abutment 1410 to which the fixing jig base 10 is coupled is also rotated. can be bound

In addition, the posterior holder abutment 1410 may be supported on the fixing jig base 10 to be fastened to the posterior teeth. Through this, a plurality of the holder abutment 1410 may be implanted in an accurate position corresponding to each of the anterior implantation points (A1) and each of the posterior implantation points (A2). In addition, the light oil insertion portion 1414 formed in each of the holder abutments 1410 may be accurately aligned in response to the bending path information (B).

At this time, in the present embodiment, the alignment coupling bar 19A constraining the fixing jig base 10 and the pivot guide jig base 20 has a cross-sectional thickness and an inner circumferential width of the alignment grooves 15 and 25, respectively. may be formed in a straight line corresponding to . Accordingly, a separate process for forming the alignment coupling bar 19A in the shape of a refraction bar can be omitted, so that manufacturing convenience and speed can be remarkably improved.

On the other hand, the pivot guide jig base 20 has a first interval w1 and a predetermined vertical interval w0 between the center point of the receiving groove 22 and the inner edge of the alignment groove 25 . It may be formed by adding the second interval w2. In this case, the first interval is preferably understood as the interval between the center point of the through hole 13 of the fixing jig base 10 and the inner edge of the alignment groove 15 . And, the second interval is the angle (θ) between the imaginary line (L) connecting the anterior implantation point (A1) and the posterior implantation point (A2) in a straight line and the both sides line (B2) is considered It is preferable to understand the interval (w2) between the both sides line (B2) and the anterior implantation point (A1).

In addition, in the pivot guide jig base 20 , the distance 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 1410 . ) can be set in excess of the interval including the radius of the upper end. That is, the bent portion of the fixing bar 1430 may be set to be spaced apart from the outside of the anterior holder abutment 1410 .

Through this, when fastening and fixing the holder abutment 1410 to the posterior implantation point A2 using the fixing jig base 10 and the pivot guide jig base 20, the light oil insertion part 1414 may be arranged parallel to the both sides of the line (B2). At the same time, bent portions at both ends of the fixing bar 1430 may be formed outside the upper end of the holder abutment 1410 fastened and fixed to the anterior side.

As such, in the present invention, the jig device for aligning and fastening the holder abutment 1410 is the holder abutment after the surgical guide 40 is separated from the oral cavity after the implantation of the implant 1 is completed. (1410) is coupled. Therefore, since the interference element is fundamentally removed when the jig device is rotated, the degree of freedom of direction adjustment is remarkably improved.

In addition, the problem that the jig device is supported on the inner circumferential surface of the guide hole 42 and rotates stiffly due to frictional force can be fundamentally eliminated. Accordingly, while the holder abutment 1410 is freely interlocked with the jig device, the opening direction of the light oil insertion part 1414 can be precisely aligned to correspond to the extension direction of the fixing bar 1430 . In addition, the size of the guide hole 42 does not need to be formed large to correspond to the outer periphery of the body portions 11 and 21 . That is, the inner periphery of the guide hole 42 may be formed to fit the size to be matched with the outer periphery of the tool required for placement of the implant 1 .

At this time, the alignment protrusion 12a formed in the jig device is inserted into the light oil insertion part 1414, and the bending path information B is taken into consideration to move the alignment coupling bar 19 in the shape of a bending bar to the alignment protrusion. The opening direction of the light oil insertion part 1414 can be precisely aligned when it is simultaneously inserted into the alignment groove 15 formed in parallel with the 12a.

Furthermore, the jig device is provided to be individually coupled to each of the holder abutments 1410, and the alignment direction of the neighboring jig device through the alignment coupling bars 19 and 19A is preset bending path information (B) and guides the fastening of the fastening screw 1420 in a restrained state in parallel with the . Accordingly, since the coupling tolerance between the jig device and the holder abutment 1410 is substantially close to zero, the accuracy of dental restoration can be significantly improved.
