[0041] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are provided only to facilitate understanding of the present invention, and are not intended to limit the scope of the present invention. The following embodiments are provided to provide a more complete description to those of ordinary skill in the art to which the invention belongs, and a detailed description of well-known structures that may cause unnecessary confusion to the technical gist of the present invention will be omitted.

[0042] Figures 1 to 3 A clamp according to a first embodiment of the present invention is shown.

[0043] Reference Figures 1 to 3 The fixture 100 described in this embodiment may include a base 110 .

[0044] The base 110 may be formed in a plate form having a predetermined width and shape. In this embodiment, a substantially disk-shaped base 110 is exemplified.

[0045] The base 110 can be installed and supported on a processing tool for processing the planting guide. For example, a drilling machine used to process guide holes on the planting guide can be installed on the base 110. In order to install such processing tools, the base 110 can have more than one mounting hole 111.

[0046] On the other hand, the clamp 100 of this embodiment may further include a fixing portion 120 .

[0047] The fixing part 120 is used to fix and support the planting guide, and can be located on the base 110. Considering the shape and height of the planting guide, the fixing part 120 can protrude from the base 110 to a predetermined degree. Alternatively, the fixing part 120 can be formed in a block shape of a predetermined shape on the base 110.

[0048] Preferably, the fixing portion 120 may be disposed at a central portion of the base 110 , so as to ensure sufficient installation space for the planting guide.

[0049] The fixing part 120 may have an upper part 121 for arranging the planting guide. The upper part 121 may be mounted with the planting guide, and for convenience, it is referred to as the "mounting surface 121". The mounting surface 121 may be formed as a plane with a predetermined width, and as required, in order to make the fixing and support of the planting guide more stable, the mounting surface 121 may be added with a predetermined shape, angle, and material.

[0050] The fixing portion 120 may have one or more guide plate coupling portions 122a, 122b, 122c, 122d. The guide plate coupling portions 122a, 122b, 122c, 122d may be disposed on the mounting surface 121. The guide plate coupling portions 122a, 122b, 122c, 122d guide the mounting position of the implantation guide plate and assist a portion of the fixing force.

[0051] There may be a plurality of guide plate joints 122a, 122b, 122c, and 122d. In this embodiment, four guide plate joints 122a, 122b, 122c, and 122d are illustrated, which is arranged in this way in consideration of the installation position guidance and stable installation of the planting guide.

[0052] As needed, the guide plate coupling portions 122a, 122b, 122c, and 122d may have a number of four or more or less in proportion. In this case, the plurality of guide plate coupling portions 122a, 122b, 122c, and 122d can be arranged in a left-right symmetric form. And when there are more than four guide plate coupling portions 122a, 122b, 122c, and 122d, the guide plate coupling portions 122a, 122b, 122c, and 122d arranged very close to the outer edge position can be arranged in a form similar to the first guide plate coupling portion 122a, the second guide plate coupling portion 122b, the third guide plate coupling portion 122c, and the fourth guide plate coupling portion 122d described later.

[0053] The shapes of the guide plate coupling portions 122a, 122b, 122c, and 122d may include shapes such as holes, grooves, protrusions, etc. that can form a mechanical coupling with the implant guide plate. In this embodiment, the illustrated guide plate coupling portions 122a, 122b, 122c, and 122d are in the form of grooves with a specified depth extending in the vertical direction of the fixing portion 120. Such guide plate coupling portions 122a, 122b, 122c, and 122d have fixing units such as clips and bars, and can form a mechanical fixed coupling with the implant guide plate.

[0054] However, as long as the guide plate coupling portions 122a, 122b, 122c, and 122d have a mechanical structure capable of disassembling and assembling the implant guide plate, they are not limited to the illustrated form. For example, the guide plate coupling portions 122a, 122b, 122c, and 122d can be embodied in an integrated form with specified fixing units, or in the form of protrusions identical to those described later Figure 6 and so on.

[0055] As in the illustrated embodiment, the guide plate coupling portions 122a, 122b, 122c, and 122d may include a first guide plate coupling portion 122a, a second guide plate coupling portion 122b, a third guide plate coupling portion 122c, and a fourth guide plate coupling portion 122d. The first guide plate coupling portion 122a, the second guide plate coupling portion 122b, the third guide plate coupling portion 122c, and the fourth guide plate coupling portion 122d can be arranged on the mounting surface 121 at specified positions and intervals.

[0056] Here, the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d can form a trapezoidal configuration structure on a plane. Alternatively, assuming that the first guide plate joint portion 122a is used as a base point, and the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d are arranged in a counterclockwise direction on a plane in sequence, then the left-right interval G1 between the second guide plate joint portion 122b and the third guide plate joint portion 122c arranged at the front portion of the mounting surface 121 can be different from the left-right interval G2 between the first guide plate joint portion 122a and the fourth guide plate joint portion 122d arranged at the front portion of the mounting surface 121.

[0057] That is, the left-right interval G1 between the second guide plate joint portion 122b and the third guide plate joint portion 122c is referred to as the first interval G1, and the left-right interval G2 between the first guide plate joint portion 122a and the fourth guide plate joint portion 122d is referred to as the second interval G2, then they can be formed in such a way that the first interval G1 and the second interval G2 are different from each other. As shown in the illustrated embodiment, the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d are arranged in a trapezoidal shape on a plane and formed in a shape where the first interval G1 is smaller than the second interval G2.

[0058] The above configuration of the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d can more effectively guide the installation position of the implant guide plate. In particular, users can intuitively grasp the installation positions of different types of implant guide plates by fixing different combinations of the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d according to the types of implant guide plates. This will be elaborated in the content related to the operation of the present invention.

[0059] Alternatively, in addition to the above trapezoidal shape, the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d can also be arranged in a shape corresponding to the shape of the dental arch. For example, the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d can be arranged in an oval shape, a polygonal shape, etc. corresponding to the shape of the dental arch.

[0060] On the other hand, the fixture 100 of this embodiment can include a buckle cover portion 130.

[0061] The cover portion 130 can fixedly support the implant guide plate between the cover portion 130 and the fixing portion 120. Specifically, the cover portion 130 can have a pressing surface 131 disposed opposite to the mounting surface 121 of the fixing portion. Generally speaking, the pressing surface 131 refers to the bottom surface portion of the cover portion 130. The implant guide plate is installed and disposed on the mounting surface 121 of the fixing portion 120, and can be fixedly supported in the jig 100 in a state where its upper portion is pressed by the pressing surface 131 of the cover portion 130.

[0062] The cover portion 130 can be disposed at a closed position for fixing the implant guide plate and an open position for detaching the implant guide plate.

[0063] Figure 1 The state where the cover portion 130 is disposed at the closed position is shown. In this case, the pressing surface 131 is disposed at a position facing the mounting surface 121, and the implant guide plate can be fixed between them. In Figure 1 the implant guide plate is omitted.

[0064] Figure 2 The state where the cover portion 130 is disposed at the open position is shown. In this case, the pressing surface 131 is disposed at a distance from the mounting surface 121, and the implant guide plate can be detached from the mounting surface 121. Alternatively, in this state, a new implant guide plate can be reinstalled on the mounting surface 121.

[0065] The cover portion 130 can be installed on the fixing portion 120 or the base 110 on the premise that it can be switched between the above-mentioned closed position and open position. As an exemplified embodiment, the cover portion 130 is fixedly attached to the rear end of the fixing portion 120 in a rotatable manner through a hinge 134, and the closed or open position can be switched as it rotates around the hinge.

[0066] On the bottom surface or the pressing surface 131 of the cover portion 130, there can be cover engaging portions 132a, cover engaging portions 132b, cover engaging portions 132c, and cover engaging portions 132d corresponding to the aforementioned guide plate engaging portions 122a, 122b, 122c, and 122d. The cover engaging portions 132a, cover engaging portions 132b, cover engaging portions 132c, and cover engaging portions 132d can be fixed to the guide plate engaging portions 122a, 122b, 122c, and 122d to assist in supporting or fixing the cover portion 130.

[0067] The lid engaging portions 132a, 132b, 132c, and 132d can be formed into structures, shapes, etc. similar to the guide plate engaging portions 122a, 122b, 122c, and 122d that can achieve mechanical engagement with holes, grooves, protrusions, etc. In this embodiment, the lid engaging portions 132a, 132b, 132c, and 132d are formed in the shape of holes that penetrate in the thickness direction of the lid portion 130 so as to be fastened to a prescribed fixing unit.

[0068] A plurality of lid engaging portions 132a, 132b, 132c, and 132d can be provided to correspond to the guide plate engaging portions 122a, 122b, 122c, and 122d. In this embodiment, the first lid engaging portion 132a, the second lid engaging portion 132b, the third lid engaging portion 132c, and the fourth lid engaging portion 132d corresponding to the first guide plate engaging portion 122a, the second guide plate engaging portion 122b, the third guide plate engaging portion 122c, and the fourth guide plate engaging portion 122d are illustrated.

[0069] As needed, the lid portion 130 can have a partition 133. The partition 133 can maintain a prescribed interval between the pressing surface 131 and the mounting surface 121.

[0070] As shown in the embodiment, the partition 133 protrudes and is formed at the bottom surface portion of the lid portion 130 adjacent to the hinge 134, one on each side. Such a partition 133, when the lid portion 130 is in the closed position, contacts the upper surface on the side of the fixing portion 120, and can maintain the interval between the pressing surface 131 and the mounting surface 121.

[0071] The jig 100 as described above operates as follows.

[0072] First, as Figure 2 shown, the lid portion 130 is in the open state. Here, it is assumed that the base 110 is installed in a processing tool such as a drilling machine for processing a dental implant guide.

[0073] When the lid portion 130 is in the open state, the dental implant guide is installed on the mounting surface 121. Here, what needs to be done on the dental implant guide includes taking an impression in the oral cavity of the subject and performing a hardening treatment of resin. For example, the dental implant guide can include the dental implant guide of the patent document with the application number 10-2019-0055759 that has been applied for.

[0074] When the above-mentioned dental implant guide is properly installed, as Figure 1As shown, the cover portion 130 is closed, and the implant guide plate can be firmly fixed between the fixing portion 120 and the cover portion 130. After fixing the implant guide plate in this way, guiding holes and the like can be appropriately processed on the implant guide plate by a drilling machine or the like. When the processing is completed, the cover portion 130 is opened again as shown in Figure 2 , and the processed implant guide plate can be taken out from the jig 100. Figure 2 As shown, it can be taken out again, and the processed implant guide plate can be taken out from the jig 100.

[0075] The form in which the implant guide plate is fixed or installed on the mounting surface 121 may vary depending on its type.

[0076] Figure 4 Various types of implant guide plates are shown. Figure 5 The form in which various types of implant guide plates are fixed to the jig is shown.

[0077] Referring to Figure 4 , the implant guide plate may have multiple types according to differences in the surgical site and the like. Figure 4 Example (a) of shows the first implant guide plate S1 extending along a partial arch shape. Figure 4 Example (b) of shows the second implant guide plate S2 extending along a half arch shape. Figure 4 Example (c) of shows the third implant guide plate S3 extending along a full arch shape. Figure 4 Example (d) of shows the fourth implant guide plate S4 of a single shape.

[0078] Referring to Figure 5 , the partial arch-shaped first implant guide plate S1 has a second fixing hole 11b and a third fixing hole 11c, and can be fixed to the second guide plate engaging portions 122b and 122c of the mounting surface 121 corresponding to the second fixing hole 11b and the third fixing hole 11c to be mounted on the jig 100. The intervals, positions, etc. of the second fixing hole 11b, the third fixing hole 11c, and the second guide plate engaging portions 122b and 122c are consistent with the set intervals and positions.

[0079] In a similar manner as described above, the semi-arch-shaped second implant guide plate may have first fixing holes 11a and second fixing holes 11b corresponding to the first guide plate joint portion 122a and the second guide plate joint portion 122b, respectively, for installation on the first guide plate joint portion 122a and the second guide plate joint portion 122b. Alternatively, the semi-arch-shaped second implant guide plate S2 may have third fixing holes 11c and fourth fixing holes 11d corresponding to the third guide plate joint portion 122c and the fourth guide plate joint portion 122d, respectively, for installation on the third guide plate joint portion 122c and the fourth guide plate joint portion 122d. Moreover, the full-arch-shaped third implant guide plate S3 may have first fixing holes 11a, second fixing holes 11b, third fixing holes 11c, and fourth fixing holes 11d corresponding to the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d, respectively. The single-shaped fourth implant guide plate may have first fixing holes 11a, second fixing holes 11b or third fixing holes 11c, fourth fixing holes 11d.

[0080] Each type of implant guide plate S1, S2, S3, and S4 can be installed on the mounting surface 121 in the above-described form. Among them, the first guide plate joint portion 122a, the second guide plate joint portion 122b, the third guide plate joint portion 122c, and the fourth guide plate joint portion 122d can guide the accurate installation positions of the implant guide plates S1, S2, S3, and S4 for the user through a unique configuration similar to a trapezoid.

[0081] However, Figure 4 the implant guide plates S1, S2, S3, and S4 are for illustration only, and it does not mean that the fixture 100 is limited to this and applicable only.

[0082] Figures 6 to 8 Show the fixture of the second embodiment of the present invention.

[0083] Below, for convenience, the description of the structures that are the same as or similar to those in the above embodiments will be omitted or briefly described only.

[0084] Refer to Figures 6 to 8 and the fixture 200 of this embodiment may include a base 210.

[0085] The base 210 can be provided as a lower structure for mounting the implant guide plate.

[0086] The base 210 of this embodiment may have a support portion 212. The support portion 212 may extend along the outer edge portion of the base 210 by a predetermined length. Moreover, the support portion 212 may protrude upward at a predetermined height.

[0087] There may be multiple supporting portions 212. A predetermined isolation space 213 may be provided between the multiple supporting portions 212, and they are arranged at intervals along the outer edge portion of the base 210. At this time, a structure may be formed in which the supporting portions 212 and the isolation spaces 213 are alternately arranged along the outer edge portion of the upper surface of the base 210. Four supporting portions 212 arranged in this way are illustrated in the figure.

[0088] As described above, the upper ends of the supporting portions 212 may contact the bottom surface of the implant guide plate to support the implant guide plate. The implant guide plate is supported on the reverse side of the fixing portion 220 by the supporting portions 212, so that a more stable and firm installation support can be obtained on the jig 200.

[0089] On the other hand, the jig 200 of this embodiment may include a fixing portion 220.

[0090] The fixing portion 220 may have a plurality of guide plate engaging portions 222a, 222b, 222c, 222d. In this embodiment, different from the foregoing embodiment, an example is shown in which each of the guide plate engaging portions 222a, 222b, 222c, 222d forms a predetermined protrusion shape.

[0091] The shapes of the respective guide plate engaging portions 222a, 222b, 222c, 222d may have various variations. For example, circular or elliptical pillars or polygonal pillars such as triangles and quadrilaterals may be formed. As needed, each of the guide plate engaging portions 222a, 222b, 222c, 222d may form a conical or polygonal pyramidal shape whose cross-section gradually becomes smaller toward the upper end, so as to facilitate its engagement with the implant guide plate.

[0092] On the other hand, the jig 200 of this embodiment may include a cover portion 230.

[0093] The cover portion 230 may be formed in the same or similar manner as in the foregoing embodiment.

[0094] On the other hand, the jig 200 of this embodiment may further include a pressing portion 240.

[0095] The pressing portion 240 may be fixed to the cover portion 230 so that the fixing portion 220 can press the cover portion 230 to form. Thus, the implant guide plate between the cover portion 230 and the fixing portion 220 can obtain a more firm and stable installation support.

[0096] The pressing portion 240 may be embodied in the form of a bolt having a screw portion 241 at one end. The other side of the screw portion 241 may have a grip portion 242 for a user or the like to hold. The screw portion 241 may penetrate the cover portion 230 and be threadedly engaged with a pressing portion fastening hole 243 located on the base 210. Thus, the pressing portion 240 can be pressurized or depressurized by manipulating the rotation to cause the cover portion 230 to be pressed by the fixing portion 220.

[0097] The operation of the fixture 200 as described above only adds part of the operation of the pressing portion 240, and the rest is similar to the operation of the foregoing embodiment, and the detailed description thereof will be omitted.

[0098] Figures 9a to 9b For Figure 6 the first modification example and the second modification example of the fixture shown.

[0099] In Figures 9a to 9b the modification example shown, the structures of the support portions 212-1 and 212-2 are different. Figure 9a The support portion 212-1 of the first modification example is shown. The upper end of the support portion 212-1 may have a groove 212a-1. The groove 212a-1 may extend in the horizontal direction on the surface of the support portion 212-1 facing the fixing portion 220. In this case, parts such as the outer edge and flange of the implant guide plate can be fixed on the groove 212a-1, and more stable fixed support can be obtained on the support portion 212-1. And, the support portion 212-1 of the first modification example may have a function of fixing the implant guide plate after being combined with the implant guide plate. The support portions 212-2, 212-3, and 212-4 of the following second to fourth modification examples also have similar functions.

[0100] Figure 9b The support portion 212-2 of the second modification example is illustrated. The support portion 212-2 shown is similar to the first modification example, and the upper surface portion 212b-2 faces the fixing portion 220 on the central side and is formed to incline downward. That is to say, the upper surface portion 212b-2 of the support portion 212b-2 of the second modification example can form an inclined surface. Such an inclined surface portion 212b-2 can more conveniently guide the implant guide plate to be fixed to the groove 212a-2.

[0101] Figures 10a to 10b For Figure 6 the third modification example and the fourth modification example of the fixture shown.

[0102] In Figures 10a to 10b the modification example shown, the structures of the support portions 212-3 and 212-4 are different, Figure 10a The support portion 212-3 of the third modification example is illustrated. Such a support portion 212-3 has a groove 212a-3 at its upper end, and the upper surface portion 212b-3 and the lower surface portion 212c-3 can form corresponding inclined surfaces with the groove 212a-3 as the center.

[0103] Figure 10bThe support portion 212-4 illustrating the fourth modification example is formed in a shape with a relatively small width in the horizontal direction.
