Description

Orthodontic anchor small plate that can expose head part to gum area {ORTHODONTIC ANCHOR MINIPLATE WITH HEAD EXPOSED IN ATTACHED GINGIVAL AREA}

The present invention relates to an orthodontic anchor small plate, and more particularly, to an orthodontic anchor small plate that can be placed in close contact with the attached gum region while exposing the head portion to the attached gingiva region adjacent to the tooth. It is about.

A typical orthodontic anchor small plate is intended for hanging the orthodontic device, which is fixed to the jawbone in the gum and the exposed part of the gum is connected to the bracket fixed to the tooth surface to apply the force for orthodontics in a specific direction. Assist. Orthodontic anchor small plates remain exposed in the oral cavity and are continually urged in the direction necessary for orthodontic treatment.

In a typical orthodontic anchor small plate, a plate is provided in the form of a plate so that the head portion extends annularly like a hook at one end of the arm portion, and a screw hole is formed at the other end of the arm portion opposite to the head portion.

Japanese Patent Application Laid-Open No. 11-164843 (published on June 22, 1999) discloses a "orthodontic support", wherein the orthodontic support is fixed to the jawbone and moved to the outside through the movable mucosa of the gum. And a hook-shaped exposed portion formed at an end of the penetrating portion to be exposed and the end of the penetrating portion. The orthodontic support from the fixed portion to the exposed portion is formed using a plate, and the through portion intersecting with the movable mucosa of the gum is also widely formed in a plate shape.

The orthodontic support has a long area exposed to the outside of the gum and is formed in a rectangular shape having a wide cross section of the penetrating part, and thus it is difficult to locate the penetrating part in the attached gum located adjacent to the tooth. Because the penetrating part is exposed through the gum from the moving gum inside the oral cavity, the exposed part is long and wide, and because the exposed part is wide and large, it is located at the lower part of the gum to avoid collision with the orthodontic device attached to the tooth. This is because they have to be exposed to the outside through flexible movable membranes.

As a result, when a patient eats food or moves his lips for pronunciation, the mucous membrane around the exposed part moves together, causing friction between the penetrating part and the gum, and a gap is created between the penetrating part and the mucous membrane. Infection of bacteria in the gum may cause inflammation, and may no longer be used as an anchor.

In contrast, Korean Patent Registration No. 804876 (August 20, 2008) discloses a surgical anchor device. The anchor device includes a fastening device that can be secured to a bone of an oral region and a clapping device connected to the fastening device. The clapping device has a rotatable rotating member and an inclined surface cooperating with the rotating member. Due to the complex structure, the size of the clapping device is inevitably increased, and since the intermediate part connected to the clapping device is connected to the back of the clapping device, it is difficult to fix the clapping device closely to the attachment gum. The part exposed to the outside of the gum is long.

The clapping device floats away from the surface of the gum, and its high vertical height prevents the exposed mucous membrane from being placed on the attached gum adjacent to the tooth to avoid collision with the orthodontic device attached to the tooth. It can only be exposed to the outside. As a result, when a patient eats food or moves his lips for pronunciation, the mucous membrane around the exposed part moves together, causing friction between the penetrating part and the gum, and a gap is created between the penetrating part and the mucous membrane. Bacteria in the infiltration may cause inflammation of the gums, and may no longer be used as an anchor.

Inflammation of the movable mucosa (gum) around the penetrating portion exposed to the outside is no longer used as an anchor is the most serious problem of the conventional orthodontic anchor small plate. The present invention provides an orthodontic anchor small plate that can be exposed to the head portion in the attachment gum to solve this problem. Attachment gum refers to the gum firmly attached to the gum bone with a width of about 5 mm or less around the teeth. The present invention provides an anchor for orthodontics that allows the anchor to penetrate the gum, thereby forming a stable attachment with the anchor and preventing inflammation.

The present invention provides an orthodontic anchor small plate capable of exposing the head short and small at the attachment gum site.

The present invention provides an orthodontic anchor small plate that can be firmly fixed to the bone structure in the oral cavity even if the incision of the gum or tissue is minimized.

The present invention provides an orthodontic anchor small plate that can reduce the number of screws or other fastening means fixed to the jawbone.

According to one exemplary embodiment of the present invention, the orthodontic anchor small plate is fixed to the bone structure in the oral cavity, an elongated arm portion, one end of which is connected to the fixing portion, and a mushroom connected to the other end of the elongate arm portion. It includes a shaped head portion, the rear surface of the head portion may be located in close contact with the attached gingiva area adjacent to the teeth.

The mushroom-shaped head portion includes a wider head than the central axis, and may include a case having a rivet head shape or a T-shaped head shape in addition to the typical mushroom shape. Because it is formed in a mushroom shape, elastic devices such as rubber bands or springs can be fixed in any direction, and can be connected with orthodontic devices such as brackets to provide a force in a certain direction. Compared with conventional hook-shaped heads, conventional anchors can be secured with rubber bands or springs approaching only in certain directions, and the hooks' direction varies depending on whether they are fixed to the left or right or up and down on the jawbone of the gum in the oral cavity. There is much. However, the anchor of the present invention provides excellent compatibility than the conventional anchor because it is possible to fix the elastic device and the like in all directions. The head part, which can apply orthodontic force in various directions, can be located adjacent to the orthodontic device attached to the tooth, thus acting as an anchor to effectively apply orthodontic force.

The other end of the elongate arm part is connected to the side of the mushroom-shaped head part, and the head part is formed to extend in the direction intersecting at the other end of the elongate arm part. As the height of the head portion is formed in the direction intersecting the elongate arm portion, the back of the head portion may be in close contact with the attached gum or teeth, and the head portion does not float in the air from the gum and is exposed out of the tissue from the head portion and the arm portion. By minimizing the part, the movement of the head part by external force can be minimized.

Here, the rear surface of the head portion may be formed into a flat surface or a curved surface closely contacting the gums so that the head portion may be in close contact with the attachment gum portion.

However, in order for the head to be located in close proximity between the attachment gum or teeth, the size of the head should be small as long as it maintains a certain strength or more. It is preferable that the height of the head portion is about 1 to 3 mm and the width is about 0.5 to 2.5 mm.

The anchor small plate of the present invention can keep the size small and can minimize the incision of the gum or tissue. For example, in the prior art, the tissue is widely cut in the dental direction and horizontally to form a wide flap. However, the anchor of the present invention can fix the fixing part even with a gap formed by a small incision of the I-shaped tissue. In particular, when dissecting tissue with an I-letter, the end of the incised portion can be positioned on the attachment gum so that only the head portion is exposed at the anchor.

The anchor small plate of the present invention has a shape in which the head portion extends perpendicular to the tip of the arm portion, while minimizing the height and width of the head portion, and minimizing the width of the arm portion, the head portion is short into the oral cavity at the attachment gum region adjacent to the teeth. It can be made small exposure. In addition, the head portion can be located directly under the orthodontic device attached to the teeth. Since the anchor is maintained in a mushroom- or button-shaped head structure, it does not require a special operation structure and can keep the size of the head exposed outside the gums small.

The anchor small plate of the present invention can be almost in close contact with the attachment gum to the outside, and the elongate arm portion can be located almost in the gum. Therefore, it is possible to prevent the occurrence of inflammation due to mutual friction between the gum and the arm. Even if the lips move, friction does not occur between the gum and the anchor, and the short and small exposure into the oral cavity facilitates the management of plaque deposited on the anchor, thereby maintaining the gums around the plate in a healthy state.

Anchor small plate of the present invention can be carried out by small incision perpendicular to the orthodontic direction during the procedure of fixing to the jawbone. Because of this, the possibility of postoperative bleeding, edema and infection complications is very low.

In the anchor small plate of the present invention, the back of the head portion is in close contact with the attachment gum to structurally limit the movement of the head portion, the screw fixed to the jawbone can reduce the number of other fastening means than conventional. This means that it is possible to reduce the area of the gum that is cut in order to expose the jaw bone in the oral cavity. In the present invention, even using only two screws can maintain the conventional fixing force.
