Description

Orthodontic and Orthodontic Assembly {ORTHODONTIC APPLIANCE AND ASSEMBLY INCLUDING THE SAME}

The present invention relates to braces and orthodontic assemblies.

In general, teeth are an important factor in personal appearance due to the appearance of images by color and shape, and the dentition due to the alignment of teeth affects not only the teeth but also the skeletal structure of the face. It is known to be an important factor in the formation of the image. In particular, in the case of a person with malformed dentition, not only the influence on the external image but also its own eating habits may cause inconvenience, and the correction of the dentition has been regarded as an important dental treatment. For this reason, orthodontics of dental treatment has a long history, and the method or technique has been remarkably developed. Orthodontic surgery, which has been widely practiced until recently, attaches one bracket to the outer tooth surface of each tooth forming the teeth, and binds a wire made of a rigid material, that is, an orthodontic wire, to the fixed structure formed on the bracket. The external physical force of the wire was to gradually correct the position or direction of each tooth over a long time.

In addition, in recent years, an increase in the procedure of attaching a bracket to the inner surface of the teeth, that is, the intraoral tongue, and connecting the wires to perform the desired orthodontic treatment by the external force of the wires Is in the trend. In addition, there is a tendency to increase the number of procedures using a transparent correction device in addition to the lingual correction device. Recently, in the known brackets having different sizes of occlusal slots and horizontal slots, the centers of the archwires being coupled to each other are displaced from each other. The same size archwires can be used interchangeably. However, this configuration has a disadvantage in that it is cumbersome in replacement and cleaning because the archwire must be connected to the orthodontic appliance attached to each tooth in the oral cavity of the patient.

Separation of the 200 can be prevented. That is, it may be more difficult to separate the restraint is made in a plurality of directions.

In particular, in the case of the insertion unit 140, it can be coupled through the shape change of the first portion (100). The shape change may include shape memory materials (SMA) or materials having elasticity, which may be deformed into specific shapes when exposed to an environment such as a predetermined temperature. It means that can be restored to the first form from. Deformation and restoration of such a shape can be carried out by various cases, but the embodiment of the present invention to be described below is based on the first form of deformation (reinforcement of the second form) and restoration of the shape (first form) Phosphorus state) will be described later.

Further, the first form is a form formed so that the coupling between the assembly 10 and the third portion 300 is maintained, the second form is the first to the first form by the resilience or resilience by the shape memory material The state which has forms other than a form can be called a 2nd form.

On the other hand, the first portion 100 may be a shape in which a portion is cut, both sides can be elastically moved in the elastic moving direction (E) based on the cut portion. That is, it may be inserted into a part of the second portion 200 through a space widened based on the cut portion, and may be narrowed and fixed by elasticity as much as the opening portion is opened. Here, to explain an example in which deformation and restoration between the first and second forms are made by elasticity, the first portion 100 is made of a shape memory alloy (SMA). If is configured to correspond to the shape deformation direction or the shape restoration direction.
