Description

Technical Field

[0001] This invention relates to a dental implant actuator. Background Technology

[0002] Originally, an implant refers to a substitute used to restore human tissue when it is missing. However, in dentistry, it refers to the root of an artificial tooth. Dental implant surgery is performed by inserting an implant made of materials such as titanium that do not cause rejection in the human body into the alveolar bone to replace the root of the missing tooth. After the bone heals, the abutment and restoration are attached to the implant.

[0003] Typically, the implant and abutment are joined by inserting the polygonal protrusions of the hexagonal abutment into the polygonal grooves of the implant. In this case, for the abutment and restoration to integrate with the implant in the desired direction, the implant must be inserted into the alveolar bone with its polygonal grooves aligned in a specific direction. In other words, for the abutment and restoration to be aligned in the desired direction, the implant must first be aligned in a specific direction within the alveolar bone.

[0004] On the other hand, after the implant is placed in the alveolar bone, the surgeon uses a dental implant actuator to fine-tune its orientation. However, since the implant is already embedded in the alveolar bone, it is difficult to accurately adjust it to the desired direction. Therefore, the surgeon needs to determine the implant's orientation by observing the relative position of the dental implant actuator and the guide template. However, existing dental implant actuators do not provide the function of confirming the implant's placement direction or its relative position to the guide template. Consequently, when using existing dental implant actuators to align the implant, the surgeon faces difficulties in accurately aligning it to the desired direction.

[0005] Existing technical documents Korean Patent Publication No. 10-1598495 (February 23, 2016) Summary of the Invention Technical issues The present invention aims to solve the problems of the prior art.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0028] Figure 1 This diagram illustrates the usage state of a dental implant actuator according to an embodiment of the present invention. Figure 2 This is a perspective view of a dental implant actuator according to an embodiment of the present invention. Figure 3 This is a diagram showing the arrangement of a dental implant actuator and implant according to an embodiment of the present invention.

[0029] Reference Figures 1 to 3 The dental implant actuator 100 of the present invention is used to align the implantation direction of the implant 30 implanted in the alveolar bone. Its lower end is connected to the implant 30 and its upper end is connected to the rotating tool 20, thereby being configured to transmit the rotational force of the rotating tool 20 to the implant 30.

[0030] On the other hand, the implant 30 is inserted into the alveolar bone through rotation around its axis, functioning as an artificial tooth root. For this purpose, the implant 30 is generally cylindrical and can be inserted into a pre-drilled hole in the alveolar bone tissue at the location where the restoration is needed. While implanted in the alveolar bone, the implant 30's insertion direction can be adjusted using the dental implant actuator 100.

[0031] The upper end face of the implant 30 has a superior groove for attaching an abutment to support the prosthesis, and the outer surface may be threaded to allow implantation into the alveolar bone. In addition, the superior groove may include an internally threaded portion 31 and a polygonal groove portion 32 from the lower side.

[0032] The internal thread portion 31 is located on the lower side of the upper groove, and its inner circumferential surface is threaded. A fastening screw for fixing the abutment can be inserted into this internal thread portion 31, as will be described later, and the support portion 110 of the dental implant actuator 100 can be inserted and supported.

[0033] The polygonal groove 32 is configured to prevent the abutment inserted into the upper groove from rotating about its axis. As described later, the insertion portion 120 of the dental implant actuator 100 can be fitted into the polygonal groove 32, whereby the rotational force of the actuator can be transmitted to the implant 30. The polygonal groove 32 preferably has a hexagonal shape, but is not limited thereto, and may have various shapes.

[0034] On the other hand, the dental implant actuator 100 can be guided by the guide template 10 when aligning the implant 30.

[0035] The guide template 10 is placed on the patient's gingiva and may have a guide hole 11 formed inside. A direction confirmation groove 12 may be formed on the upper part of the guide template 10. At least one direction confirmation groove 12 may be formed around the guide hole 11. For example, the guide template 10 may be made of a 3D printing material such as resin.

[0036] The guide hole 11 is a component of the movement path of at least one of the drill bit, implantation driver, and implant orientation alignment driver during the implantation surgery, and can be formed into a hole shape that passes through the center of the guide template 10.

[0037] The orientation confirmation groove 12 can be used for aligning the implant orientation using the dental implant actuator 100. Specifically, the orientation confirmation groove 12 can be pre-formed incised at the position where the polygonal groove portion 32 of the implant 30 should be arranged. As described later, the operator can align the implant 30 orientation by aligning the identification element 141 of the dental implant actuator 100 with the orientation confirmation groove 12 of the guide template 10.

[0038] Reference Figures 1 to 3 The dental implant actuator 100 may include, from the bottom side, a support portion 110, an insertion portion 120, an extension portion 130, a first direction recognition portion 140, a second direction recognition portion 150, and a mounting portion 160.

[0039] The support portion 110 is located at the lower end of the dental implant actuator 100 and can be positioned closer to the implant 30 than the insertion portion 120 when engaged with the implant 30. The support portion 110 can be made to have a diameter smaller than the internal thread portion 31 of the implant 30. This allows the dental implant actuator 100 to easily enter the upper groove of the implant 30. Furthermore, during rotation for orientation alignment, the support portion 110 can be supported in the internal thread portion 31, thereby smoothly facilitating the rotation of the dental implant actuator 100 and the orientation alignment of the implant 30.

[0040] The insertion portion 120 may be formed in a polygonal shape to fit snugly into the polygonal groove 32 of the implant 30, thereby transmitting the rotational force generated by the rotating tool 20 to the implant 30. According to one embodiment, the insertion portion 120 may be formed in a hexagonal shape with six faces.

[0041] Mounting section 160 is located at the upper end of dental implant actuator 100 and can be coupled with rotating tool 20. Mounting section 160 may have a robust fixing structure to prevent rotating tool 20 from detaching. After the operator mounts rotating tool 20 to mounting section 160 of dental implant actuator 100, force can be applied to rotating tool 20 to fine-tune the orientation of implant 30.

[0042] The first direction identification portion 140 is located above the insertion portion 120 and is configured to align the implantation direction of the implant 30. The first direction identification portion 140 may be formed in a generally cylindrical shape so that it can be guided by the guide hole 11 of the guide template 10. That is, the outer diameter of the first direction identification portion 140 may be formed to be consistent with the inner diameter of the guide hole 11 or have a predetermined tolerance.

[0043] On the other hand, at least one identification element 141 may be formed on the outer peripheral surface of the first direction identification portion 140, and the direction of the identification element 141 is consistent with the direction of at least one surface of the polygonal insertion portion 120, so as to align the implantation direction of the implant 30.

[0044] Since the orientation of the identification element 141 is consistent with the orientation of at least one face of the insertion portion 120 in the polygonal groove portion 32 of the implant 30, the identification element 141 can perform the function of indicating the implantation orientation of the implant 30.

[0045] That is, the operator can align the direction of the implant 30 by aligning the identification element 141 of the dental implant actuator 100 with the direction confirmation groove 12 of the guide template 10.

[0046] According to one embodiment, at least one identification element 141 may be formed at equal intervals around the outer periphery of the identification portion 140 in the first direction. In this case, the identification elements 141 may be formed in the same number as the number of faces of the polygonal insertion portion 120.

[0047] The identification element 141 can be formed as an engraved groove on the outer peripheral surface of the first direction identification portion 140, and can be colored to facilitate identification by the surgeon. Since the identification element 141 is formed as an engraved groove, guide elements 142 guided by guide holes 11 of guide template 10 can be formed between the identification elements 141.

[0048] On the other hand, when aligning the direction of the implant 30, the surgeon usually aligns the direction confirmation groove 12 of the guide template 10 with the identification element 141 of the dental implant actuator 100 from the buccal direction. However, in the case of a molar, it is difficult to ensure the field of vision, so it is sometimes difficult to confirm whether the direction confirmation groove 12 and the identification element 141 are consistent.

[0049] To address the aforementioned issues, the dental implant actuator 100 may include a second direction recognition section 150 located above the first direction recognition section 140 and used to assist in aligning the implantation direction of the implant 30.

[0050] Since the second direction recognition part 150 is located above the first direction recognition part 140 and is not part of the guide hole 11 of the insertion guide template 10, the surgeon can use the second direction recognition part 150 to help confirm the implantation direction of the implant 30 and adjust it when it is difficult to ensure the field of vision.

[0051] According to one embodiment, the second direction recognition part 150 may include at least one corner 151 or surface 152, the direction of which is consistent with the direction of the recognition element 141.

[0052] At this time, the corner 151 or surface 152 of the second direction recognition portion 150 may at least partially be in a shape that protrudes radially compared to the first direction recognition portion 140.

[0053] Thus, if the direction of the corner 151 or the surface 152 of the second direction recognition part 150 is configured to be consistent with the direction of the recognition element 141, the surgeon can easily align the direction of the implant 30 by aligning the corner 151 or the surface 152 of the second direction recognition part 150 with the direction confirmation groove 12 of the guide template 10.

[0054] The second direction recognition portion 150 is preferably formed in an equilateral triangular shape. If the second direction recognition portion 150 is formed in an equilateral triangular shape, the corners 151 or faces 152 are arranged at 60° intervals, which facilitates aligning the corners 151 or faces 152 with the direction confirmation groove 12 of the guide template 10. In addition, the surgeon can fine-tune the insertion depth of the implant 30 when the dental implant actuator 100 is known to how far the implant 30 enters each 60° rotation.

[0055] Figure 4 Parts (a) and (b) are a perspective view and a plan view, respectively, showing the state before implant orientation alignment using a dental implant actuator according to an embodiment of the present invention. Figure 5 Parts (a) and (b) are a perspective view and a plan view, respectively, showing the state after implant orientation alignment using a dental implant actuator according to an embodiment of the present invention.

[0056] Reference Figure 4 and Figure 5 In situations where it is difficult to ensure a clear field of vision, such as in the molar region, and it is difficult to align the identification element 141 of the first direction identification part 140 with the direction confirmation groove 12 of the guide template 10, the surgeon can easily align the direction of the implant 30 by rotating the second direction identification part 150, which is shaped like an equilateral triangle, so that the corner 151 or the face 152 is aligned with the direction confirmation groove 12.

[0057] Figures 6 to 9 This is a diagram illustrating various embodiments of the dental implant actuator of the present invention.

[0058] Reference Figure 6 According to the second embodiment, the second direction recognition portion 250 of the implant driver 200 may have a shape in which a blade portion 251 protrudes radially to both sides. The end of the blade portion 251 may have a shape including a face or an angle, the direction of which may be consistent with the direction of the recognition element 141 of the first direction recognition portion 140. That is, the surgeon can align the direction of the implant 30 by aligning the face or angle of the blade portion 251 with the direction confirmation groove 12 of the guide template 10.

[0059] Reference Figure 7According to the third embodiment, the second direction recognition portion 350 of the implant actuator 300 may have a shape in which a blade portion 351 protrudes radially to one side. The end of the blade portion 351 may have a shape including a face or an angle, the direction of which may be consistent with the direction of the recognition element 141 of the first direction recognition portion 140. That is, the surgeon can align the direction of the implant 30 by aligning the face or angle of the blade portion 351 with the direction confirmation groove 12 of the guide template 10.

[0060] Reference Figure 8 According to the fourth embodiment, the second direction recognition portion 450 of the implant actuator 400 can be formed in a fan shape. This fan-shaped second direction recognition portion 450 may have a shape including a surface, preferably including a curved surface 451, the center direction of which may be consistent with the direction of the recognition element 141 of the first direction recognition portion 140. That is, the surgeon can align the direction of the implant 30 by aligning the center of the curved surface 451 of the second direction recognition portion 450 with the direction confirmation groove 12 of the guide template 10.

[0061] Reference Figure 9 According to the fifth embodiment, the second direction recognition portion 550 of the implant actuator 500 can be formed in a hexagonal shape. Each face of this hexagonal second direction recognition portion 550 can be arranged to align with the direction of the recognition element 141 of the first direction recognition portion 140. That is, the surgeon can align the implant 30 by aligning one face 551 of the second direction recognition portion 550 with the direction confirmation groove 12 of the guide template 10.

[0062] Thus, the dental implant actuator of the present invention includes a first direction recognition part and a second direction recognition part, which can easily determine the implantation direction of the implant in the alveolar bone even when it is difficult to ensure the field of vision during implantation surgery, and can intuitively align the implant in the desired direction.
