The base portion 210 may include a base portion body 211. The base portion body 211 may be configured on an object (eg, Figure 1 The oral structure of the subject 10) (e.g.: Figure 1 On or above the surface of the first jawbone 11 and / or the second jawbone 12).

[0039] The base part 210 may include a plurality of (eg, 9) through bodies 212. The plurality of through bodies 212 may be inserted into an object (eg, Figure 1 The base body 211 is configured to be inserted into an oral structure (e.g., the first jawbone 11 and / or the second jawbone 12) of the subject 10 in the embodiment. When the plurality of through bodies 212 enter the oral structure, biological substances (e.g., blood) generated from the oral structure may flow between the oral structure and the base body 211. The base body 211 may be bonded (e.g., combined) to the surface of the oral structure through the biological substances.

[0040] The plurality of through bodies 212 can be fixed to an object (eg: Figure 1 The base body 211 can be stably maintained on or above the oral structure.

[0041] The dental screw 200 may include a fixing member 220. The fixing member 220 may be provided in a manner that can be coupled to a ring (e.g. Figure 1 The fixing member 220 may be configured to be coupled to the base 210 in a manner that the fixing member 220 is coupled to the first ring 121, the second ring 122 and / or the third ring 123 in the base 210. The fixing member 220 may be configured to be coupled to the base 210 in a manner that the fixing member 220 is coupled to the thread of the base 210.

[0042] Figure 4 A three-dimensional diagram of a base portion of an embodiment. Figure 5 A top view of a base portion of an embodiment. Figure 6 A bottom view of a base portion of an embodiment. Figure 7 For an embodiment based on Figure 6 A cross-sectional view of the base portion along line 7-7.

[0043] Reference Figures 4 to 7 The base part 210 may include a base body 211. The base body 211 may include: a first base surface 211A (eg, a front surface of the base); a second base surface 211B (eg, a rear surface of the base) located on the opposite side of the first base surface 211A; and a side base surface 211C located between the first base surface 211A and the second base surface 211B.

[0044] The diameter or width of the first base surface 211A may be smaller than the diameter or width of the second base surface 211B. In an embodiment not shown, the diameter or width of the first base surface 211A may be substantially the same as the diameter or width of the second base surface 211B. In an embodiment not shown, the diameter or width of the first base surface 211A may be larger than the diameter or width of the second base surface 211B.

[0045] The side base surface 211C may include a plurality of side surfaces 211D. For example, the side base surface 211C may actually include a plurality of surfaces having linear curves (e.g., flat surfaces). The plurality of side surfaces 211D of the side base surface 211C may form a regular polygon that is actually connected along the circumferential direction (e.g., Figure 5 In this structure, if a tool (e.g., an octagonal wrench) is used toward the side base surface 211C, the base portion 210 can be relative to an object (e.g., Figure 1 The user (e.g., a dentist) places the base 210 at a desired position of the object, and can use a first tool (e.g., a fixing member 220) to initially rotate and fix the base 210 in the corresponding position, and can use a second tool (e.g., an octagonal wrench) to more firmly fix the base 210 that is at least partially in the corresponding position. The side base surface 211C may include a curved surface connected to the first base surface 211A. In this structure, the foreign body sensation felt by the object 10 can be reduced.

[0046] The base portion 210 may include a plurality of through bodies 212. The plurality of through bodies 212 may be disposed on the second base surface 211B.

[0047] The through body 212 may include a first perforated surface 212A. The first perforated surface 212A may be along a first circumferential direction R1 (eg, Figure 6 ) is inclined at a first angle p1 to the second base surface 211B.

[0048] The through body 212 may include a second perforated surface 212B. The second perforated surface 212B may be along a second circumferential direction R2 (eg, Figure 6 The second circumferential direction R2 may be opposite to the first circumferential direction R1.

[0049] The size of the first angle p1 may be smaller than the size of the second angle p2. The first angle p1 may be about 25 degrees or more, about 30 degrees or more, about 35 degrees or more, about 40 degrees or more, about 45 degrees or more, about 50 degrees or more, or about 55 degrees or more. The first angle p1 may be about 65 degrees or less, about 60 degrees or less, about 55 degrees or less, about 50 degrees or less, or about 45 degrees or less. The second angle p2 may be about 70 degrees or more, about 75 degrees or more, about 80 degrees or more, about 85 degrees or more, or about 90 degrees or more. The second angle p2 may be about 110 degrees or less, about 105 degrees or less, about 100 degrees or less, or about 95 degrees or less. In this specification, "about" or "actual" may be defined as a tolerance level of ±1%, ±2%, ±5%, or ±10% of a specified value. In this angle range, a plurality of through bodies 212 may enter an object (e.g., a smaller force) during rotation along the first circumferential direction R1. Figure 1 Oral tissue of subject 10) (e.g.: Figure 1 The first jawbone 11 and / or the second jawbone 12 in the base 210). After the plurality of through bodies 212 are coupled to the oral tissue of the subject, they cannot be easily removed therefrom. For example, a structure in which the second angle p2 is relatively larger than the first angle p1 can allow the plurality of through bodies 212 to enter the oral tissue when the base 210 rotates along the first circumferential direction R1, and can prevent the plurality of through bodies 212 from being separated from the oral tissue when the base 210 rotates along the second circumferential direction R2.

[0050] The area of ​​the first perforated surface 212A may be greater than the area of ​​the second perforated surface 212B.

[0051] The first perforated surface 212A may be inclined in a radially outer direction relative to the second base surface 211B. The second perforated surface 212B may be inclined in a radially outer direction relative to the second base surface 211B. When viewed from the second base surface 211B toward the first base surface 211A, the projection of the tip portion T overlaps with or offsets an edge portion of the second base surface 211B.

[0052] The through body 212 may include an outer side perforated surface 212C. The outer side perforated surface 212C may be located between the first perforated surface 212A and the second perforated surface 212B. The outer side perforated surface 212C may face the outer direction of the second base surface 211B (eg, Figure 6 The outer side perforated surface 212C may be connected to the side base surface 211C (eg, monolithically). The outer side perforated surface 212C may include a curved surface.

[0053] The through body 212 may include an inner side perforated surface 212D. The inner side perforated surface 212D may be located between the first perforated surface 212A and the second perforated surface 212B. The inner side perforated surface 212D may face the inner direction of the second base surface 211B (eg, Figure 6 The inner side perforated surface 212D may be opposite to the outer side perforated surface 212C. The inner side perforated surface 212D may be connected to the second base surface 211B (e.g., monolithically). The inner side perforated surface 212D may include a curved surface.

[0054] The through-body 212 may include a tip portion T. The tip portion T may be formed by the intersection of the first perforated surface 212A, the second perforated surface 212B, the outer side perforated surface 212C, and the inner side perforated surface 212D. The tip portion T may be embodied by the edge between the first perforated surface 212A and the second perforated surface 212B. It may extend in a radial direction relative to the second base surface 211B. In one embodiment, the tip portion T may be actually parallel to at least a portion of the second base surface 211B. In one embodiment, the tip portion T may be inclined in a radial direction relative to the second base surface 211B. When the plurality of through-bodies 212 first begin to enter the oral tissue of the subject, the area in which the plurality of through-bodies 212 contact the oral tissue may be reduced, so that the plurality of through-bodies 212 may enter the oral tissue with relatively little force.

[0055] The distance between the projection of the tip portion T on the second base surface 211B and the portion where the first perforated surface 212A intersects with the second base surface 211B may be smaller than the distance between the projection of the tip portion T on the second base surface 211B and the portion where the second perforated surface 212B intersects with the second base surface 211B. This prevents the plurality of through bodies 212 from being easily disengaged due to external force when entering and being inserted into the oral tissue of the subject. Therefore, the base body 211 can be stably maintained on the surface of the oral tissue.

[0056] The plurality of through bodies 212 may be arranged along the edge of the second base surface 211B toward the peripheral direction of the second base surface 211B. In one embodiment, the plurality of through bodies 212 may be directly connected in a manner that they are not separated from each other. For example, the first perforated surface 212A of one through body 212 in a pair of adjacent through bodies 212 may be directly connected to the second perforated surface 212B of the other through body 212. In one embodiment, the plurality of through bodies 212 may be separated from each other. For example, the interval between a pair of adjacent through bodies 212 may be actually the same as the interval between another pair of adjacent through bodies 212.

[0057] The base portion 210 may include a hole 213. The hole 213 may substantially include a circular shape. The hole 213 may penetrate the first base surface 211A and the second base surface 211B.

[0058] The base portion 210 may include a first engagement portion 214. The first engagement portion 214 may be located at a side of the hole 213. The first engagement portion 214 may be formed with a thread.

[0059] The base portion 210 may include a depression 215. The depression 215 may be disposed on the second base surface 211B along a direction toward the first base surface 211A. The depression 215 may actually include a curved surface. The depression 215 may form an edge area A2 that is distinguished from the central area A1. The plurality of through bodies 212 may be disposed in the edge area A2. The plurality of through bodies 212 may not be disposed in the central area A1.

[0060] Figure 8 The figure is a three-dimensional view of a fixing member according to an embodiment observed from one direction. Fig. 9 It is a three-dimensional view of a fixing member according to an embodiment observed from another direction.

[0061] Reference Figure 8 and Fig. 9 , the fixing member 220 may include a fixing member body 221. The fixing member body 221 may include: a first fixing member surface 221A (e.g., the front surface of the fixing member); a second fixing member surface 221B (e.g., the rear surface of the fixing member), which is located on the opposite side of the first fixing member surface 221A; and a side fixing member surface 221C, which is located between the first fixing member surface 221A and the second fixing member surface 221B. The fixing member body 221 may actually include a cylindrical shape. In an embodiment not shown in the figure, the side fixing member surface 221C may form a polygonal shape. For example, the side fixing member surface 221C can be formed in a shape that is aligned with the ring (e.g., Figure 1 The first ring 121, the second ring 122 and / or the third ring 123) are meshed with each other.

[0062] The fixing member 220 may include a fixing member head 222. The fixing member head 222 may protrude from the first fixing member surface 221A. In one embodiment, the fixing member head 222 may be in a polygonal shape. In an embodiment not shown, the fixing member head 222 may be in a circular shape.

[0063] The maximum width or maximum diameter of the fixing member head 222 may be greater than the maximum width or maximum diameter of the side fixing member surface 221C. The protruding length of the fixing member head 222 may be less than the length of the side fixing member surface 221C. In an embodiment not shown, the protruding length of the fixing member head 222 may be greater than the length of the side fixing member surface 221C.

[0064] The fixing member 220 may include a second engagement portion 223. The second engagement portion 223 may protrude from the second fixing member surface 221B. The second engagement portion 223 may be configured to engage with the hole (eg, Figures 2 to 7 The first meshing portion (for example: Figures 2 to 7 For example, the second engagement portion 223 may be formed with a thread matching the thread of the first engagement portion 214.

[0065] The protruding length of the second engaging portion 223 can be substantially equal to the length of the hole (eg: Figures 4 to 7 The protruding length of the second engaging portion 223 may be greater than the hole (e.g.: Figures 4 to 7 For example, when the fixing member 220 is engaged with the base portion (eg, Figures 4 to 7 When the base portion 210 in the middle is combined, one end of the second engagement portion 223 can be on the second base surface (for example: Figures 4 to 7 One side of the second base surface 211B) protrudes.
