Referring to FIG. 1A, the orthodontic anchoring system 10 according to an embodiment is used by being fixed to a bone in oral tissue. For example, the anchoring system 10 may be connected to a coupling element F1 fixed to each tooth T through a connector C1. In this example, it is understood that the anchoring system 10 is connected directly to the tooth T. The anchoring system 10 may include a base 110 and a fixing member 130.

The base 110 is configured to adhere to the bone. Here, "adhesion" means to be fluidly attached. Therefore, that the base 110 adheres to the bone may be understood as the base 110 is attached to the bone in a state where a fluid is mediated between the bone and a partial surface of the base 110. In one example, the fluid may include a biological fluid or an artificial fluid. In a preferred example, the fluid may comprise a biological fluid. In a more preferred example, the fluid may comprise blood.

The fixing member 130 is coupled to the base 110 and is configured to fix the base 110 to the bone. For example, the fixing member 130 may include a screw commonly used in the dental field, but is not necessarily limited thereto, and any means capable of fixing the base 110 to the bone may be used.

Referring to FIG. 1B, the orthodontic anchoring device 10 including the base 110 and the fixing member 130 according to an embodiment includes a bracket B configured to be fixed to a tooth T for orthodontics. It is connected to the passing wire (W) through the connector (C2). In this example, it can be understood that the orthodontic anchoring device 10 is indirectly connected to the tooth T. Orthodontic anchoring device 10 may also be anchored to the oral tissue in which the root (not shown) of the tooth (T), as shown in FIG. 1B.

2 is a perspective view of an anchoring device according to an embodiment, FIG. 3 is a bottom view of the anchoring device according to an embodiment, and FIG. 4 is a cross-sectional view of the anchoring device according to an embodiment.

2 to 4, the anchoring system 10 according to an embodiment may include a base 110 and a fixing member 130.

The base 110 is defined by an attaching surface 111 that is attached to the oral tissue of the subject, a non-adhesive surface 112 that is not attached to the oral tissue of the subject, and the attaching surface 111 and the non-adhesive surface 112 It has an inner space (113).

The attachment surface 111 may be formed in a mesh shape. For example, the attachment surface 111 may include a plurality of transverse ribs 111A extending in the transverse direction and a plurality of longitudinal ribs 111B extending in the longitudinal direction. A plurality of transverse ribs 111A and a plurality of longitudinal ribs 111B may cross each other to form a mesh shape of the attachment surface 111. An opening 1111 may be formed between an adjacent pair of transverse ribs 111A and an adjacent pair of longitudinal ribs 111B. The plurality of openings 1111 may be in fluid communication with the inner space 113. The attachment surface 111 in the form of a mesh may help the base 110 to be better attached to the oral tissue of the object, especially bone.

Attachment surface 111 may be subjected to any suitable surface treatment to facilitate adhesion of the subject to oral tissue. For example, the adhesion surface 111 may be subjected to a surface treatment such as phosphorus hydroxide coating treatment and SLA surface treatment (Sandblasted Large-grit Acid-etched Surface treatment). When the base 110 is embedded in the oral tissue of the object, such a surface treatment of the attachment surface 111 promotes the osteocyte activity of the direct contact portion between the base 110 and the oral tissue, especially the bone. It can shorten the adhesion time between the and oral tissue.

Non-adhesive surface 112 is a surface defining the top of base 110. The non-adhesive surface 112 may be formed convex relative to the attaching surface 111. Further, the non-adhering surface 112 may include a non-concave portion 112A and a concave portion 112B. The non-concave portion 112A and the concave portion 112B may be formed alternately along the circumferential direction of the base 110. In addition, the non-adhesive surface 112 may include a neck portion 112C extending in the upward direction.

The attachment surface 111 and the non-adherence surface 112 may be formed of a bio-friendly material. For example, the attaching surface 111 and the non-adhering surface 112 may be formed of titanium. This is to prevent the base 110 from generating a rejection reaction to the object while the base 110 is fixed to the oral tissue for a long time.

The base 110 may include a coupling portion 114 to which the fixing member 130 is coupled. The coupling portion 114 extends from the top to the bottom of the base 110 and may be formed on the inner surface of the base 110. For example, the coupling portion 114 may have a shape of a female thread. An inner space 113 may be formed between the coupling portion 114 and the attachment surface 111.

The fixing member 130 may be coupled to the coupling portion 114. The fixing member 130 may not entirely penetrate the base 110 but only partially pass through and may be fixed to the base 110. For example, the fixing member 130 may have a male thread shape.

5 and 6, the anchoring system 10 according to an embodiment may include a piercing member 120. The piercing member 120 may be configured to induce a flow of a biological fluid between the oral tissue DT and the attachment surface 111 of the base 110 by damaging a portion of the oral tissue DT. Piercing member 120 may vary in length and thickness according to the maxillary and mandibular use. For example, the lower school piercing member 120 may have a thicker and longer shape than the upper school piercing member 120.

Hereinafter, a process in which the base 110 of the anchoring system 10 adheres to the oral tissue will be described.

First, the attachment surface 111 of the base 110 may be disposed to face the oral tissue DT, especially bone.

Thereafter, the piercing member 120 sequentially passes through the opening formed in the coupling portion 114, the inner space 113 and the attachment surface 111, and the end 121 of the piercing member 120 is formed of the oral tissue DT. You can damage it by piercing some of it. At this time, the biological fluid BF may come out from the damaged oral tissue DT. The biological fluid BF may flow between the attachment surface 111 and the oral tissue DT.

Thereafter, the attachment surface 111 of the base 110 may adhere to the oral tissue DT, in particular, the bone through the biological fluid BF.

On the other hand, since the adhesion process between the adhesion surface 111 and the oral tissue DT requires a long time, the adhesion surface 111 adheres to the oral tissue DT to a considerable extent through a small amount of biological fluid BF. The piercing member 120 may fix the base 110 to the oral tissue DT. To this end, the piercing member 120 may be formed with a coupling element 122 in the form of a male thread that can be coupled to the coupling portion 114. In this case, the end of the piercing member 120 may be fixed to the oral tissue DT.

Thereafter, although not shown, the piercing member 120 may be removed from the base 110 by sufficiently inducing the flow of the biological fluid BF and then exiting from the opening, the inner space 113 and the coupling portion 114. Thereafter, in order to fix the base 110 to the oral tissue DT and to be connected to another oral tissue, for example, a tooth T (see FIG. 1 ), the fixing member 130 shown in FIGS. 1 to 3 previously May be fixed to the coupling portion 114.

Referring to FIG. 7, the anchoring system 10 according to an embodiment may include a cap 140. The cap 140 is in a state in which the attachment surface 111 of the base 110 is attached to the oral tissue DT after the piercing member 120 described in FIGS. 5 and 6 is removed from the base 110, Before the fixing member 130 described in FIGS. 1A, 1B, 2 and 3 is fixed to the base 110, it may be configured to cover the coupling portion 114. The cap 140 may include a coupling element 141 in the form of a male thread that is coupled to the coupling portion 114. Since the cap 140 has a predetermined length, it may take a form protruding from the base 110 when coupled to the base 110. This prevents foreign matter from accumulating in the internal space 113 defined inside the base 110 until the attachment surface 111 is attached to the oral tissue DT to a considerable extent and the base 110 is fixed to the oral tissue DT. While preventing, it is possible to prevent oral tissues around the base 110 from covering the base 110. In other words, the cap 140 may perform a function of visually displaying the position of the base 110 to a user or an operator.

Referring to FIG. 8, the anchoring device 10 ′ according to an embodiment includes an attachment surface 111, a non-attachment surface 112, and an anchoring system 10 as described in FIGS. 2 to 4, It may include an inner space 113, an opening 1111 formed in the attachment surface 111, and a base 110 ′ including a coupling portion 114.

In this embodiment, the base 110 ′ may include a protruding member 115 surrounding at least a portion of the periphery of the opening 1111 formed in the attachment surface 111. The protruding member 115 may protrude from the attachment surface 111. In this embodiment, the base 110 ′ may rotate about the rotation axis X-X. While the base 110 ′ rotates with respect to the rotation axis X-X, the protrusion member 115 also rotates with respect to the rotation axis X-X and may damage a part of the oral tissue DT. A biological fluid may come out from the damaged oral tissue DT, and the biological fluid flows between the attachment surface 111 and the oral tissue DT, and prevents adhesion between the attachment surface 111 and the oral tissue DT. Can be mediated.

As described above, although the embodiments have been described by the limited drawings, a person of ordinary skill in the art can apply various technical modifications and variations based on the above. For example, the described techniques are performed in a different order from the described method, and/or components such as a system, structure, device, circuit, etc. described are combined or combined in a form different from the described method, or other components Alternatively, even if substituted or substituted by an equivalent, an appropriate result can be achieved.

Therefore, other implementations, other embodiments, and equivalents to the claims fall within the scope of the following claims.
