Description

Technical Field

[0001] The present invention relates to a surgical guide device for dental implant surgery. Background Art

[0002] Generally, a dental implant assembly means an artificial substitute configured to reproduce the same form and function as natural teeth, and includes: an implant made of titanium, which is a substitute for natural teeth, has threads formed on its outer peripheral surface, and is disposed in the alveolar bone; a dental abutment, which is connected to the upper part of the implant and has an artificial tooth attached to its upper part; and a fixing screw for fixing the implant and the dental abutment to each other.

[0003] A surgical method for the dental implant assembly is briefly described as follows: First, the gum of the patient is incised to expose the alveolar bone. Next, a position for inserting the implant is determined in the exposed alveolar bone, and a part of the alveolar bone is removed at the position using a perforating tool such as a drilling device to form a hole for implanting the implant. After that, the dental abutment is fastened to the implant implanted in the formed hole, and a dental crown is placed on the dental abutment while ending the dental implant surgery.

[0004] Generally, when performing dental implant surgery, after incising the gum to expose the alveolar bone, it is difficult to accurately grasp the exact position and direction of the perforation operation when directly performing perforation above it by drilling or the like. Therefore, an additional surgical guide device is usually used.

[0005] When drilling, the surgical guide device serves to accurately guide the formation direction, position, and depth of the perforation.

[0006] The surgical guide device is provided in a shape corresponding to a part or the whole of the dentition of the patient and includes a guide hole corresponding to the dental implant surgery position. However, when the interarch distance of the patient is not sufficient, there is a problem that it is difficult to insert the drilling device into the guide hole.

[0007] To solve this problem, as Figure 1 shown, a guide sleeve 3 was conventionally formed in the surgical guide device 1. The guide sleeve 3 extends along the guide hole 2 and has an open side surface. Specifically, as Figure 2 shown, an axial slit 4 is formed in the side surface of the guide sleeve 3, and the drilling device can enter from the side through the axial slit 4.

[0008] However, since the conventional drilling device stands axially along the axial slit 4 and enters the guide hole 2, there is still a problem that it is difficult for the drilling device to enter when the dental implant surgery position is adjacent to the temporomandibular joint like the molar region.

[0009] Further, as the side surface portion of the open guide sleeve 3 is pushed against the open side surface portion of the guide sleeve 3 by the centrifugal force of the drilling when the head of the drilling device drills, there is a problem of reduced accuracy of the drilling. Summary of the Invention

[0010] Technical Problem

[0011] The present invention is used to solve the problems of the aforementioned prior art. The object of the present invention is to provide a dental implant surgery guiding device that can not only facilitate the entry of the drilling device but also ensure the accuracy of the drilling.

[0012] Solution to the Problem

[0013] An embodiment of the present invention provides a guide sleeve, which includes: a guide body, which is a hollow structure with a guide hole formed in the center and in contact with the outer peripheral surface of the drill bit of the drilling device, and one side of the side surface portion of the guide body is open; and a pair of anti-disengagement portions, which extend along the circumference of the guide body from the left and right end portions of the guide body respectively and are spaced apart from each other, and an inclined slit is formed therebetween.

[0014] In one embodiment, the pair of anti-disengagement portions may be spaced apart by a distance equal to or greater than the diameter of the perforating mechanism of the drilling device and equal to or less than the outer diameter of the drill bit.

[0015] In one embodiment, the first anti-disengagement portion may be formed such that the circumferential length decreases as it goes downward along the axial direction of the guide hole, and the second anti-disengagement portion may be formed such that the circumferential length decreases as it goes upward along the axial direction of the guide hole.

[0016] In one embodiment, the opposing surfaces of the pair of anti-disengagement portions may be formed as flat surfaces.

[0017] In one embodiment, the opposing surfaces of the pair of anti-disengagement portions may be formed as curved surfaces with a specified curvature.

[0018] In one embodiment, the guide body and the pair of anti-disengagement portions can be formed in a manner having the same curvature.

[0019] An embodiment of the present invention provides a dental implant surgery guiding device, which includes a guide sleeve. The dental implant surgery guiding device includes: a bracket that surrounds the buccal surface, lingual surface, and occlusal surface of a tooth; and a surgical portion that has a through hole in contact with the outer periphery of the guide sleeve along the dental implant surgery position on the bracket and has an opening portion formed on one side of the side surface portion to expose the side surface portion.

[0020] Another embodiment of the present invention provides an implant surgery guiding device, which includes: a bracket surrounding the buccal surface, lingual surface and occlusal surface of a tooth; a surgical part corresponding to the implant surgery position, having a through hole in contact with the outer circumferential surface of the drill bit of a drilling device, and having an opening formed on one side; and a guiding part formed at the opening of the surgical part and having an inclined slit through which the perforating mechanism of the drilling device can pass obliquely.

[0021] In one embodiment, the guiding part may include a first anti-disengagement part and a second anti-disengagement part. The first anti-disengagement part and the second anti-disengagement part extend along the periphery of the opening from the left and right end portions of the opening respectively and are spaced apart from each other, and the inclined slit is formed therebetween.

[0022] In one embodiment, the first anti-disengagement part and the second anti-disengagement part may be spaced apart by a distance equal to or greater than the diameter of the perforating mechanism of the drilling device and equal to or less than the outer diameter of the drill bit.

[0023] In one embodiment, the first anti-disengagement part may be formed such that the circumferential length decreases as it goes downward along the axial direction of the through hole, and the second anti-disengagement part may be formed such that the circumferential length decreases as it goes upward along the axial direction of the through hole.

[0024] In one embodiment, the facing surfaces of the first anti-disengagement part and the second anti-disengagement part may be formed as flat surfaces.

[0025] In one embodiment, the facing surfaces of the first anti-disengagement part and the second anti-disengagement part may be formed as curved surfaces with a specified curvature.

[0026] In one embodiment, the surgical part and the first anti-disengagement part and the second anti-disengagement part can be formed in a manner having the same curvature.

[0027] In one embodiment, the surgical part and the guiding part may be formed integrally.

[0028] Effects of the Invention

[0029] According to one embodiment of the present invention, the drill bit can enter in a horizontal state at a specified angle by means of the inclined slit. Thus, in the case of a narrow intermaxillary space such as in the molar region, it is convenient for the drill bit to enter.

[0030] Moreover, by means of the inclined slit, the opening angle of the drill bit will be reduced compared with the prior art. Thus, the drilling device can be more stably supported on the inner circumference of the surgical part or the guide sleeve, and therefore, the accuracy of drilling can be improved.

[0031] It should be understood that the effects of the present invention are not limited to the above effects, but include all effects that can be deduced from the specific embodiments of the present invention or the structure of the invention described in the claims. Description of the Drawings

[0046] Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention can be embodied in various different forms, and thus is not limited to the embodiments described herein. Moreover, in order to accurately describe the present invention, parts irrelevant to the description in the drawings are omitted, and throughout this specification, similar parts are given similar reference numerals.

And when it is stated that a certain part "includes" a certain structural element, unless there is a particularly contrary description, it means that other structural elements are also included, rather than excluding other structural elements.

[0048] Ordinal terms such as "first" or "second" used in this specification can be used to describe various structural elements or steps, but the above-mentioned structural elements or steps are not limited by the ordinal numbers. Ordinal terms are only used to distinguish one structural element or step from other structural elements or steps.

[0049] Figure 3 is a perspective view of the implant surgery guiding device according to the first embodiment of the present invention. Figure 4 is a perspective view, a top view, and a front view of the guiding sleeve according to the first embodiment of the present invention.

[0050] Hereinafter, with reference to Figure 3 and Figure 4 the implant surgery guiding device 100 according to the first embodiment of the present invention will be described in detail.

[0051] The implant surgery guiding device 100 according to the first embodiment of the present invention includes a bracket 110, a surgical part 120, and a guiding sleeve 130.

[0052] The bracket 110 can be formed to surround the buccal, lingual, and occlusal sides of the tooth. Specifically, the bracket 110 can be formed to cover the buccal surface, the lingual surface, and the occlusal surface, where the buccal surface is the surface facing the cheek, the lingual surface is the surface facing the tongue, and the occlusal surface is the surface in contact with the tooth.

[0053] In Figure 3 although the bracket 110 is shown as being formed in a shape covering the entire mandible, the bracket 110 can be formed to cover the entire or a part of the maxilla or cover the entire or a part of the mandible according to the number or position of the dental prostheses to be implanted, and thus is not limited thereto. In other words, in addition to the shape surrounding the entire dentition, in the case where a part of the dentition is lost, the bracket 110 can also be formed to surround a part of the corresponding dentition.

[0054] The bracket 110 can be formed in a manner that conforms to the outer surface profiles of the gums and dental crowns of the subject to be operated on.

[0055] Preferably, a plurality of through-holes 111 are formed on one side of the bracket 110. At this time, the through-holes 111 can be formed in a manner that penetrates the surface of the bracket 110, and it is possible to confirm whether the gums and teeth of the subject to be operated on are accurately conforming to the inner shape of the bracket 110 through the through-holes 111.

[0056] Preferably, the lingual sides of the bracket 110 are connected to each other by the strengthening parts 112. Specifically, the strengthening parts 112 connect the lingual sides of the bracket 110 arranged in an opposing manner, thereby ensuring the high durability of the bracket 110.

[0057] The surgical part 120 can be formed on the upper part of the bracket 110, and in the center of the surgical part 120, a circular through-hole 121 penetrates toward the gum side. Specifically, in the case where the bracket 110 is in the shape arranged in the upper jaw, the through-hole 121 can be recessed upward, and in the case where the bracket 110 is in the shape arranged in the lower jaw, the through-hole 121 can be recessed downward.

[0058] According to the number of perforations for implanting implants, more than one through-hole 121 can be formed. That is, more than one through-hole 121 can be formed so that the perforation parts of the alveolar bone are respectively arranged coaxially. In the case of forming a plurality of through-holes 121, the through-holes 121 can be arranged in a manner corresponding to each perforation part. The surgical part 120 can be formed integrally so that the plurality of through-holes 121 are arranged in a row along the dental arch.

[0059] The drilling device 10 can be rotationally supported on the inner circumferential surface of the through-hole 121. Specifically, the through-hole 121 can be formed to have an inner diameter that contacts the outer circumferential surface of the drill bit 11, so that the outer circumferential surface of the drill bit 11 of the drilling device 10 supports the rotation of the perforating mechanism 12 in a contacting state.

[0060] An opening part 122 can be formed on the side surface part of the surgical part 120 so that the drilling device 10 can be inserted into the inside of the through-hole 121 from the buccal side. For example, the surgical part 120 can be formed in an arc shape with an open buccal side, that is, the cross-section is formed in a C shape.

[0061] Among them, the opening part 122 can be formed on the buccal side facing the inner surface of the cheek of the subject to be operated on, but is not limited thereto, and can be formed on the lingual side which is the surface facing the tongue, and can be formed on both the buccal side and the lingual side at the same time.

[0062] In addition, in the surgical site 120a on the molar side, the opening amount of the oral cavity is restricted, making it difficult for the surgical drilling device 10 to enter. Therefore, preferably, an opening portion 122 is formed, but it is not limited thereto. It may also be like the surgical site 120b, as long as a space can be ensured when opening and closing the oral cavity, even without the opening portion 122.

[0063] Refer to Figure 3 and Figure 4 , the guide sleeve 130 may include a hollow-structured guide body 131. A guide hole 132 is formed in the center of the guide body 131, and the guide body 131 extends along the axial direction of the guide hole 132. The guide sleeve 130 can be inserted into the through hole 121 of the surgical site 120 and supported on the inner peripheral surface of the through hole 121.

[0064] In an exemplary embodiment, the surgical site 120 and the guide sleeve 130 may be formed integrally. In this case, when performing the surgery, the process of combining the guide sleeve 130 with the surgical site 120 is omitted, so the usability for the user can be improved.

[0065] The drilling device 10 can be rotatably supported on the inner peripheral surface of the guide body 131. Specifically, the guide hole 132 can be formed to have an inner diameter that contacts the outer peripheral surface of the drill bit 11, so that the rotation of the perforation mechanism 12 is supported in a state where it contacts the outer peripheral surface of the drill bit 11 of the drilling device 10.

[0066] On the other hand, the guide sleeve 130 can be formed to open the buccal side, so that the drilling device 10 is inserted into the inside of the guide hole 132 in the buccal direction. The guide sleeve 130 can be cut to expose the buccal side. The guide sleeve 130 can form an inclined slit 135 by opening the buccal side. Specifically, the guide body 131 can be formed in an arc shape with the buccal side open, that is, the cross section is formed in a C shape.

[0067] On the other hand, as described above, in the existing guide sleeve, a slit parallel to the axial direction is formed. Thus, when the implant surgery site is adjacent to the jaw joint like the molar side, it is difficult to enter the guide hole of the surgical drilling device, and when drilling, the drill bit of the drilling device is pushed toward the open side surface of the guide sleeve due to centrifugal force, resulting in a problem of reduced drilling accuracy.

[0068] For this reason, the guide sleeve 130 according to an embodiment of the present invention is characterized by including a pair of anti - detachment portions 133a, 133b that form the inclined slit 135.

[0069] The inclined slit 135 may be inclined at a predetermined angle with respect to the axial direction of the guide sleeve 130. According to various embodiments of the present invention, as the inclined slit 135 is inclined with respect to the axial direction of the guide sleeve 130, the drill bit 11 can enter at a predetermined angle in a horizontally placed state. That is, in the case of a narrow jaw space, the drill bit 11 can enter easily.

[0070] Wherein, since the width D of the inclined slit 135 is formed to be equal to or greater than the diameter of the perforating mechanism 12 of the drilling device 10 and equal to or less than the outer diameter of the drill bit 11, although the perforating mechanism 12 can pass through the inclined slit 135, the drill bit 11 will not disengage from the inclined slit 135.

[0071] In one embodiment, the inclined slit 135 may maintain the formed angle and extend toward the bracket 110 side. That is, the inclined slit 135 can extend downward in a long manner, and in this case, the drilling device 10 can enter the inclined slit 135 more easily.

[0072] A pair of anti-disengagement portions 133a, 133b may extend along the circumference of the guide body 131 from the left and right end portions 131a, 131b on the open side of the guide body 131, respectively, and are formed in a spaced-apart manner.

[0073] Specifically, as going downward along the axial direction of the guide sleeve 130, the circumferential length of the first anti-disengagement portion 133a may gradually decrease, and as going upward along the axial direction of the guide sleeve 130, the circumferential length of the second anti-disengagement portion 133b may gradually decrease. Among them, the guide body 131 and the first anti-disengagement portion 133a, the second anti-disengagement portion 133b can be formed in a manner having the same curvature.

[0074] In an exemplary embodiment, as shown in part (b) of Figure 4 , when viewed from above, the width of the inclined slit 135 may be different from the width D of the inclined slit 135 when viewed from the front as shown in part (c) of Figure 4 . When the inclined slit 135 is viewed from the front of the guide sleeve 130, the width D may be greater than the width of the inclined slit 135 when viewed from above. According to various embodiments of the present invention, when the guide sleeve 130 is viewed from the front, since the drilling device 10 enters from the buccal side in an inclined state, it can enter with a relatively wide width D, making the entry easier. When drilling with the drilling device 10, the drilling device 10 is arranged parallel to the axial direction, so when the guide sleeve 130 is viewed from above, disengagement can be prevented due to the relatively narrow width.

[0075] For example, if the circumferential lengths formed along the axial direction of the guide sleeve 130 of the first anti-disengagement portion 133a and the second anti-disengagement portion 133b constantly decrease, then as shown in Figure 4part (a) of Figure 4 As shown in part (c) of Figure 4 the opposing surfaces 134a, 134b of a pair of anti - detachment parts 133a, 133b can be formed as planes, and an inclined slit 135 is formed between the first anti - detachment part 133a and the second anti - detachment part 133b. In an exemplary embodiment, as

[0076] Figure 5 This is another example of the guide sleeve according to the first embodiment of the present invention.

[0077] Specifically, when viewed from the side, the opposing surfaces 134a', 134b' of the first anti - detachment part 133a' and the second anti - detachment part 133b' of the guide sleeve 130' can be formed as curved surfaces with a specified curvature. In this case, the inclined slit 135' of the guide sleeve 130' can be formed in a curved shape.

[0078] Figure 6 This is the front view of the state where the drilling device 10 is combined with the guide sleeve 130 of the first embodiment of the present invention and the existing guide sleeve 3. Figure 7 is Figure 6 the cross - sectional view in the A - A direction and the cross - sectional view in the B - B direction of

[0079] Hereinafter, with reference to Figure 6 and Figure 7 a detailed comparison between the guide sleeve 130 of the first embodiment of the present invention and the existing guide sleeve 3 will be made.

[0080] In the existing drill bit 11 inserted into the guide sleeve 3, a part of the outer periphery of the drill bit 11 is exposed to the buccal side from the axial slit 4. At this time, the opening angle α of the drill bit 11 with respect to the guide sleeve 3 can be defined as the angle formed by a pair of open ends x1, x2 of the guide sleeve 3 and the rotation axis C of the drill bit 11.

[0081] On the contrary, the inclined slit 135 of the guide sleeve 130 of the first embodiment of the present invention is formed in an oblique direction, so that the upper part of the drill bit 11 contacts y1 which is the circumferential end of the first anti - detachment part 133a, and the middle part of the drill bit 11 contacts y2 which is the circumferential end of the second anti - detachment part 133b. That is, the opening angle β of the drill bit 11 with respect to the guide sleeve 130 can be defined as the angle formed by the ends b1, b2 of the first and second anti - detachment parts 133a, 133b and the rotation axis C of the drill bit 11.

[0082] Among them, compared with the existing contact points x1 and x2, the contact points y1 and y2 of the drill bit 11 and the guide sleeve 130 move inward.

[0083] That is, an inclined slit 135 is formed in the guide sleeve 130 so that the opening angle β of the drill bit 11 with respect to the guide sleeve 130 is reduced compared to the existing opening angle α. Thus, the drilling device 10 can be more stably supported on the inner circumference of the guide sleeve 130, thereby improving the accuracy of drilling.

[0084] Figure 8 It is a diagram showing the usage method of the implant surgery guiding device 100 according to the first embodiment of the present invention.

[0085] Hereinafter, with reference to Figure 8 The usage method of the implant surgery guiding device 100 according to the first embodiment of the present invention will be described in detail.

[0086] The guide sleeve 130 is coupled to the inner peripheral surface of the through hole 121 of the surgical part 120 so that the inclined slit 135 faces the opening part 122 of the surgical part 120. Then, the perforating mechanism 12 of the drilling device 10 is inclined to match the inclination angle of the inclined slit 135 and passes through the opening part 122 and the inclined slit 135.

[0087] When the perforating mechanism 12 is inserted into the guide hole 132 of the guide sleeve 130, the inclined drilling device 10 is rectified so that the outer peripheral surface of the drill bit 11 is inserted downward toward the guide hole 132 in a manner of surface contact with the inner peripheral surface of the guide body 131.

[0088] For this purpose, the drilling device 10 can be rotationally supported along the inner circumference of the guide sleeve 130 and can form a perforation in the alveolar bone in the axial direction of the guide hole 132.

[0089] In this way, even when there is not enough space to insert the drilling device 10, the drilling device 10 can pass through the side surface of the surgical part 120 through the opening part 122 and the inclined slit 135 formed on the side surface of the surgical part 120 and the guide sleeve 130, and can be easily inserted into the inside of the guide hole 132 of the guide sleeve 130. Therefore, the usability of the product can be improved.

[0090] Moreover, excessive oral opening or compression of the cheek / corner of the mouth for inserting the drilling device 10 can be minimized. Therefore, the inconvenience to the patient can be significantly reduced.

[0091] Moreover, an inclined slit 135 is formed in the guide sleeve 130, so that the opening angle β of the drill bit 11 with respect to the guide sleeve 130 is reduced compared to the existing opening angle α. Thus, the drilling device 10 can be more stably supported on the inner circumference of the guide sleeve 130, thereby improving the accuracy of drilling.

[0092] Figure 9 A perspective view of the implant surgery guiding device according to the second embodiment of the present invention Figure 10 A perspective view, a top view, and a front view of the surgical part and the guiding part according to the second embodiment of the present invention.

[0093] Hereinafter, with reference to Figure 9 and Figure 10 , the implant surgery guiding device 200 according to the second embodiment of the present invention will be described in detail. Hereinafter, parts that are repeated with the foregoing embodiments will be omitted, and similar components will be given similar reference numerals (however, the detailed positional relationships are in accordance with the drawings corresponding to each embodiment).

[0094] The implant surgery guiding device 200 according to the second embodiment of the present invention includes a bracket 210, a surgical part 220, and a guiding part 230.

[0095] In the implant surgery guiding device 200 according to the second embodiment of the present invention, the guiding part 230 and the surgical part 220 are formed integrally, which is different from the foregoing embodiment in this regard.

[0096] The guiding part 230 is located on the side of the open part 222 of the surgical part 220, and is used to guide the drilling device 20 into the through hole 221 of the surgical part 220 and is formed integrally with the surgical part 220.

[0097] The guiding part 230 according to an embodiment of the present invention includes a pair of anti - detachment parts 233a, 233b, and an inclined slit 235 is formed to guide the drilling device 10 to enter the through hole 221 of the surgical part 220 in an inclined manner.

[0098] Specifically, the inclined slit 235 may be inclined at a predetermined angle with respect to the axial direction of the through hole 221. According to various embodiments of the present invention, as the inclined slit 235 of the guiding part 230 is inclined with respect to the axial direction of the side surface of the surgical part 220, the drill bit 11 can enter at a predetermined angle in a horizontally placed state. That is, in the case of a narrow intermaxillary distance, the drill bit 11 can easily enter.

[0099] Among them, since the width D of the inclined slit 235 is formed to be equal to or greater than the diameter of the perforating mechanism 12 of the drilling device 10 and equal to or less than the outer diameter of the drill bit 11, although the perforating mechanism 12 can pass through the inclined slit 235, the drill bit 11 will not detach from the inclined slit 235.

[0100] In one embodiment, the inclined slit 235 can maintain the formed angle and extend toward the bracket 210 side. That is, the inclined slit 235 can extend downward in a long manner, and in this case, the drilling device 10 can more easily enter the inclined slit 235.

[0101] A pair of anti - detachment portions 233a, 233b can extend respectively along the periphery of the surgical portion 220 from the left and right end portions of the open portion 222 and are formed in a spaced - apart manner.

[0102] Specifically, as going downward along the axial direction of the through - hole 221 from the upper part of the open portion 222, the circumferential length of the first anti - detachment portion 233a can gradually decrease, and as going upward along the axial direction of the through - hole 221 from the lower part of the open portion 222, the circumferential length of the second anti - detachment portion 233b can gradually decrease. Among them, the surgical portion 220 and the first anti - detachment portion 233a, the second anti - detachment portion 233b can be formed in a manner having the same curvature.

[0103] In an exemplary embodiment, Figure 10 as shown in part (b) of [], when observed from above, the width of the inclined slit 235 can be different from the width D of the inclined slit 235 when observed from the front as shown in part (c) of []. When observing the guiding portion 230 from the front, the width D of the inclined slit 235 can be greater than the width of the inclined slit 235 when observed from above. According to various embodiments of the present invention, when observing the guiding portion 230 from the front, since the drilling device 10 enters from the buccal side in an inclined state, it can enter with a relatively wide width D, making the entry easier. When drilling using the drilling device 10, the drilling device 10 is arranged parallel to the axial direction, so when observing the guiding portion 230 from above, detachment can be prevented due to the relatively narrow width. Figure 10 For example, if the circumferential lengths formed along the axial direction of the through - hole 221 in the first anti - detachment portion 233a and the second anti - detachment portion 233b constantly decrease, then as shown in part (a) of [] and part (c) of [], the facing surfaces 234a, 234b of the pair of anti - detachment portions 233a, 233b can be formed as planes, and an inclined slit 235 is formed between the first anti - detachment portion 233a and the second anti - detachment portion 233b. In an exemplary embodiment, as shown in [] Figure 10

[0104] Figure 10 Figure 10 Figure 10 Figure 10 Figure 10 Figure 10As shown in part (c), when viewed from the buccal side, the opposing surfaces 234a and 234b of the first anti-disengagement portion 233a and the second anti-disengagement portion 233b can be formed in a straight line shape. The interval between the opposing surfaces 234a and 234b can be formed to be constant, but is not limited thereto. Also, the circumferential lengths of the first anti-disengagement portion 233a and the second anti-disengagement portion 233b can be reduced at different ratios.

[0105] Figure 11 This is another example of the guiding portion of the second embodiment of the present invention.

[0106] Specifically, when viewed from the side, the opposing surfaces 234a' and 234b' of the first anti-disengagement portion 233a' and the second anti-disengagement portion 233b' of the guiding portion 230' can be formed as curved surfaces with a specified curvature. In this case, the inclined slit 235' of the guiding portion 230' can be formed in a curved shape.

[0107] Figure 12 This is the front view of the state where the drilling device is combined with the surgical portion, the guiding portion, and the existing guiding portion of the second embodiment of the present invention. Figure 13 This is Figure 12 The cross-sectional view in the A-A direction and the cross-sectional view in the B-B direction of

[0108] Hereinafter, with reference to Figure 12 and Figure 13 the surgical portion 220, the guiding portion 230, and the existing guiding portion 3 of the second embodiment of the present invention will be compared in detail.

[0109] In the existing drill bit 11 inserted into the guiding portion 3, a part of the outer circumference of the drill bit 11 is exposed to the buccal side from the axial slit 4. At this time, the opening angle α of the drill bit 11 with respect to the guiding portion 3 can be defined as the angle formed by a pair of open ends x1 and x2 of the guiding portion 3 and the rotation axis C of the drill bit 11.

[0110] On the contrary, the inclined slit 235 of the guiding portion 230 of the present invention is formed in an oblique line direction such that the upper part of the drill bit 11 contacts y1 which is the circumferential end of the first anti-disengagement portion 233a, and the middle part of the drill bit 11 contacts y2 which is the circumferential end of the second anti-disengagement portion 233b. That is, the opening angle β of the drill bit 11 with respect to the surgical portion 220 can be defined as the angle formed by the circumferential ends y1 and y2 of the first anti-disengagement portion 233a and the second anti-disengagement portion 233b and the rotation axis C of the drill bit 11.

[0111] Among them, the contact points y1 and y2 of the drill bit 11 and the guiding portion 230 move inward compared to the existing contact points x1 and x2.

[0112] That is, an inclined slit 235 is formed in the guiding portion 230 such that the opening angle β of the drill bit 11 with respect to the surgical portion 220 is reduced compared to the existing opening angle α. As a result, the drilling device 10 can be more stably supported on the inner periphery of the surgical portion 220 and the guiding portion 230, thereby improving the accuracy of drilling.

[0113] Figure 14 The figure showing the usage method of the implant surgery guiding device according to the second embodiment of the present invention.

[0114] Hereinafter, with reference to Figure 14 The usage method of the implant surgery guiding device 200 according to the second embodiment of the present invention will be described in detail.

[0115] Tilt the perforating mechanism 12 of the drilling device 10 to match the inclination angle of the inclined slit 235 and pass through the inclined slit 135.

[0116] When the perforating mechanism 12 is inserted into the through-hole 221 of the surgical portion 220, straighten the tilted drilling device 10 so that the outer peripheral surface of the drill bit 11 faces the lower side of the through-hole 221 in a manner of surface contact with the inner peripheral surface of the surgical portion 220 and insert it.

[0117] For this purpose, the drilling device 10 can be rotationally supported along the inner periphery of the surgical portion 220 and can form a perforation in the alveolar bone in the axial direction of the through-hole 221.

[0118] In this way, even when there is not enough space to insert the drilling device 10, the drilling device 10 can pass through the side surface of the surgical portion 220 through the inclined slit 235 and can be easily inserted into the inside of the through-hole 221 of the surgical portion 220. Therefore, the usability of the product can be improved.

[0119] Moreover, excessive oral opening or compression of the cheek / corner of the mouth for inserting the drilling device 10 can be minimized. Therefore, the inconvenience to the subject can be significantly reduced.

[0120] Furthermore, an inclined slit 235 is formed by means of the guiding portion 230 such that the opening angle β of the drill bit 11 with respect to the surgical portion 220 is reduced compared to the existing opening angle α. As a result, the drilling device 10 can be more stably supported on the inner periphery of the surgical portion 220 and the guiding portion 230, thereby improving the accuracy of drilling.
