Description

Dental Implant Driver

[0001] The present invention relates to a dental implant driver.

[0002] While implants originally referred to replacements for lost human tissue, in dentistry they refer to artificial tooth roots. Dental implant surgery involves placing an implant made of titanium, a material the body will not reject, into the alveolar bone, allowing it to fuse, and then attaching an abutment and prosthesis to the implant.

[0003] Typically, the implant and abutment are joined by inserting the polygonal projections of the abutment, which are formed in a hexagonal shape, into the polygonal grooves of the implant. For the abutment and prosthesis to be bonded to the implant in the desired orientation, the implant must be placed in the alveolar bone with the polygonal grooves aligned in a specific direction. In other words, for the abutment and prosthesis to be aligned in the desired direction, the implant must first be aligned in a specific direction with the alveolar bone.

[0004] Meanwhile, after the surgeon places the implant in the alveolar bone, he or she uses a dental implant driver to finely adjust the direction of the implant. However, since the implant is already placed in the alveolar bone, it is difficult to precisely align the implant in the desired direction. Therefore, the surgeon must determine the direction of the implant through the relative positional relationship between the dental implant driver and the guide template. However, conventional dental implant drivers do not provide a function to confirm the implant placement direction or the relative positional relationship with the guide template. Accordingly, when the surgeon aligns the implant with a conventional dental implant driver, it was difficult to precisely align the implant in the desired direction.

[0027] Hereinafter, the present invention will be described with reference to the attached drawings. However, the present invention can be implemented in various different forms and is therefore not limited to the embodiments described herein. In the drawings, irrelevant parts have been omitted for clarity of description, and similar parts have been designated with similar reference numerals throughout the specification.

[0028] Throughout the specification, when a part is said to be "connected" to another part, this includes not only "directly connected" but also "indirectly connected" with other elements intervening. Furthermore, when a part is said to "include" a component, this does not exclude other components, but rather implies that the other components may be included, unless otherwise specifically stated.

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0030] FIG. 1 is a diagram showing a state of use of a dental implant driver according to one embodiment of the present invention, FIG. 2 is a perspective view of a dental implant driver according to one embodiment of the present invention, and FIG. 3 is a diagram arranging a dental implant driver and an implant according to one embodiment of the present invention.

[0031] Referring to FIGS. 1 to 3, the dental implant driver (100) of the present invention is configured to align the implantation direction of an implant (30) implanted in an alveolar bone, and the lower end is coupled with the implant (30), and the upper end is coupled with a rotary tool (20) to transmit the rotational force of the rotary tool (20) to the implant (30).

[0032] Meanwhile, the implant (30) is inserted into the alveolar bone according to a rotational movement about an axis and functions as an artificial tooth root. To this end, the implant (30) has a roughly cylindrical shape and can be inserted into a pre-formed bore hole within the bone tissue of the alveolar bone at a location where a prosthesis is required. The implant (30) can have its implantation direction adjusted by a dental implant driver (100) while it is implanted in the alveolar bone.

[0033] An upper groove is formed on the upper surface of the implant (30) to which an abutment for supporting a prosthesis is attached, and a screw thread may be formed on the outer surface to enable implantation into the alveolar bone. In addition, the upper groove may include an internal screw portion (31) and a polygonal groove portion (32) from the lower side.

[0034] The internal threaded portion (31) is a portion positioned on the lower side of the upper groove, and has threads formed on its inner surface. A fastening screw for fixing an abutment can be coupled to this internal threaded portion (31), and as described below, a support portion (110) of a dental implant driver (100) can be inserted and supported.

[0035] The polygonal groove (32) is configured to prevent the abutment inserted into the upper groove from rotating about the axis. As described below, the insertion portion (120) of a dental implant driver (100) can be inserted into the polygonal groove (32) so as to fit therein, thereby transmitting the rotational force of the driver to the implant (30). The polygonal groove (32) may preferably have a hexagonal shape, but is not limited thereto and may have various shapes.

[0036] Meanwhile, the dental implant driver (100) can be guided by a guide template (10) when aligning the direction of the implant (30).

[0037] The guide template (10) is installed on the patient's gums (gingival) and a guide hole (11) may be formed inside. At this time, the guide template (10) may have a groove (12) formed on the upper portion for direction confirmation. At least one such groove (12) for direction confirmation may be formed around the guide hole (11). For example, the guide template (10) may be manufactured from a 3D printing material such as resin.

[0038] The guide hole (11) is a configuration that guides the movement path of at least one of a drill, an implant placement driver, and an implant direction alignment driver during the implant procedure, and can be formed in the shape of a hole penetrating the center of the guide template (10).

[0039] The groove (12) for direction confirmation may be a groove used when aligning the direction of an implant using a dental implant driver (100). Specifically, the groove (12) for direction confirmation may be engraved in advance at a position where one side of the polygonal groove (32) of the implant (30) should be aligned, and as described below, the operator can align the direction of the implant (30) by aligning the identification element (141) of the dental implant driver (100) and the groove (12) for direction confirmation of the guide template (10).

[0040] Referring to FIGS. 1 to 3, a dental implant driver (100) may include, from the lower 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).

[0041] The support part (110) is provided at the lower end of the dental implant driver (100), and can be positioned closer to the implant (30) than the insertion part (120) when combined with the implant (30). The support part (110) can be manufactured to have a smaller diameter than the internal thread part (31) of the implant (30). Accordingly, the dental implant driver (100) can easily enter the upper groove of the implant (30). In addition, when the support part (110) is rotated to align the direction of the implant, the rotation of the dental implant driver (100) and the aligning of the direction of the implant (30) can be smoothly performed.

[0042] The insertion portion (120) may be formed in a polygonal shape so as to be inserted into the polygonal groove portion (32) of the implant (30) and may transmit rotational force from 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.

[0043] The mounting portion (160) is provided at the upper end of the dental implant driver (100) and can be combined with the rotary tool (20). The mounting portion (160) can have a rigid fixing structure to prevent the rotary tool (20) from being detached. After the operator mounts the rotary tool (20) to the mounting portion (160) of the dental implant driver (100), the operator can finely adjust the direction of the implant (30) by applying force to the rotary tool (20).

[0044] The first direction recognition unit (140) is located on the upper side of the insertion unit (120) and is configured to align the implantation direction of the implant (30). The first direction recognition unit (140) may be formed in a roughly cylindrical shape so as to be guided by the guide hole (11) of the guide template (10). That is, the outer diameter of the first direction recognition unit (140) may be formed to match the inner diameter of the guide hole (11) or to have a predetermined tolerance.

[0045] Meanwhile, on the outer surface of the first direction recognition part (140), one or more identification elements (141) may be formed whose direction matches at least one side of the polygonal insertion part (120) to align the implantation direction of the implant (30).

[0046] Since the identification element (141) matches the direction of at least one side of the insertion portion (120) that is fitted into the polygonal groove portion (32) of the implant (30), the identification element (141) can perform the function of indicating the implantation direction of the implant (30).

[0047] That is, the operator can align the direction of the implant (30) by aligning the identification element (141) of the dental implant driver (100) and the direction confirmation groove (12) of the guide template (10).

[0048] According to one embodiment, one or more identification elements (141) may be formed at equal intervals along the outer periphery of the first direction recognition unit (140). In this case, the number of identification elements (141) may be formed equal to the number of faces of the polygonal insertion unit (120).

[0049] The identification element (141) may be formed in a negative groove shape on the outer surface of the first direction recognition part (140) and may be color-processed to facilitate recognition by the operator. As the identification element (141) is formed in a negative groove shape, a guide element (142) that is guided to the guide hole (11) of the guide template (10) may be formed between the identification elements (141).

[0050] Meanwhile, when aligning the direction of the implant (30), the practitioner generally aligns the groove (12) for direction confirmation of the guide template (10) with the identification element (141) of the dental implant driver (100) in the buccal direction. However, in the case of molars, it is difficult to secure a field of vision, so it is sometimes difficult to confirm whether the groove (12) for direction confirmation and the identification element (141) are aligned.

[0051] To solve this, the dental implant driver (100) may include a second direction recognition unit (150) located above the first direction recognition unit (140) to assist in aligning the implantation direction of the implant (30).

[0052] Since the second direction recognition unit (150) is located on the upper side of the first direction recognition unit (140) and is not configured to be inserted into the guide hole (11) of the guide template (10), the operator can auxiliary check and adjust the implantation direction of the implant (30) through the second direction recognition unit (150) when it is difficult to secure a field of vision.

[0053] According to one embodiment, the second direction recognition unit (150) may include at least one angle (151) or surface (152) whose direction matches that of the identification element (141).

[0054] At this time, the angle (151) or surface (152) of the second direction recognition unit (150) may be at least partially protruded in the radial direction more than the first direction recognition unit (140).

[0055] In this way, when the direction of the angle (151) or surface (152) of the second direction recognition unit (150) is configured to match the direction of the identification element (141), the operator can easily align the direction of the implant (30) by aligning the angle (151) or surface (152) of the second direction recognition unit (150) with the direction confirmation groove (12) of the guide template (10).

[0056] This second direction recognition part (150) may preferably be formed in an equilateral triangle shape. When the second direction recognition part (150) is formed in an equilateral triangle shape, the angles (151) or the surfaces (152) are arranged at 60° intervals, making it easy to align the angles (151) or the surfaces (152) with the grooves (12) for confirming the direction of the guide template (10). In addition, the practitioner can finely adjust the depth of entry of the implant (30) knowing how far the implant (30) enters when the dental implant driver (100) rotates 60°.

[0057] (a) and (b) of FIG. 4 are a perspective view and a plan view, respectively, showing a state before alignment of an implant using a dental implant driver according to an embodiment of the present invention, and (a) and (b) of FIG. 5 are a perspective view and a plan view, respectively, showing a state after alignment of an implant using a dental implant driver according to an embodiment of the present invention.

[0058] Referring to FIGS. 4 and 5, in cases where it is difficult to secure a field of vision, such as in the molar region, and thus it is difficult to align the identification element (141) of the first direction recognition unit (140) with the direction confirmation groove (12) of the guide template (10), the operator can easily align the direction of the implant (30) by rotating the angle (151) or surface (152) of the second direction recognition unit (150), which is in the shape of an equilateral triangle, so that it aligns with the direction confirmation groove (12).

[0059] Figures 6 to 9 are drawings showing various embodiments of the dental implant driver of the present invention.

[0060] Referring to Fig. 6, the second direction recognition unit (250) of the implant driver (200) according to the second embodiment may have a shape in which a blade (251) is formed to protrude on both sides in the radial direction. The end of the blade (251) may have a shape including a surface or an angle, and the surface or angle may be aligned in a direction with the identification element (141) of the first direction recognition unit (140). That is, the operator can align the direction of the implant (30) by aligning the surface or angle of the blade (251) with the direction confirmation groove (12) of the guide template (10).

[0061] Referring to Fig. 7, the second direction recognition unit (350) of the implant driver (300) according to the third embodiment may have a shape in which a blade (351) protrudes in one radial direction. The end of the blade (351) may have a shape including a surface or an angle, and the surface or angle may be aligned in a direction with the identification element (141) of the first direction recognition unit (140). That is, the operator can align the direction of the implant (30) by aligning the surface or angle of the blade (351) with the direction confirmation groove (12) of the guide template (10).

[0062] Referring to Fig. 8, the second direction recognition unit (450) of the implant driver (400) according to the fourth embodiment may be formed in a fan shape. This fan-shaped second direction recognition unit (450) may be in the form of a surface, preferably a curved surface (451), and the center of the curved surface (451) may be aligned with the direction of the identification element (141) of the first direction recognition unit (140). That is, the operator can align the direction of the implant (30) by aligning the center of the curved surface (451) of the second direction recognition unit (450) with the direction confirmation groove (12) of the guide template (10).

[0063] Referring to Fig. 9, the second direction recognition unit (550) of the implant driver (500) according to the fifth embodiment may be formed in a hexagonal shape. Each side of the second direction recognition unit (550) having such a hexagonal shape may be arranged so that its direction matches that of the identification element (141) of the first direction recognition unit (140). That is, the operator can align the direction of the implant (30) by aligning one side (551) of the second direction recognition unit (550) with the direction confirmation groove (12) of the guide template (10).

[0064] In this way, the dental implant driver of the present invention includes a first direction recognition unit and a second direction recognition unit, so that even in situations where it is difficult to secure a field of vision during implant surgery, the implantation direction of the implant placed in the alveolar bone can be easily identified and the implant can be intuitively aligned in the desired direction.

[0065] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single entity may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner.
