Description

Adjustable lingual brackrt positioner

The present invention relates to an apparatus for precisely arranging a lingual orthodontic bracket attached to a model of a tooth for orthodontics in the field of dentistry.

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. 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.

Against this background, orthodontics have a long history in dental treatment, and the method or technique has also 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 orthodontic teeth and binds a wire, that is, a wire made of a strong material that forms an orthodontic arc, to the fixed structure formed on the bracket. It was a method to gradually correct the position or direction of each tooth over a long time by the external physical force of the wire.

However, in the above method, a structure in which a bracket having a predetermined size is attached to the outer tooth surface of each tooth and each bracket is connected by an orthodontic arc wire is used for the vision of an outsider during the daily life of the individual who needs to undergo long-term adjustment treatment. Since it has to be exposed to, it has aesthetic problems. Recently, a bracket is attached to the inner surface of the teeth, that is, the intraoral tongue side of the tooth, and a wire is attached thereto to fix the desired orthodontic teeth by the external force of the wire. There is an increasing trend of procedures that allow the procedure to be performed. This method is extremely preferred among individuals who are treated because the orthodontic structure itself is concealed by the teeth, but the dentists performing the procedure handle the brackets and bind the wires to the fixing structures of the brackets. There is an inconvenient work to do this, and some improvement has been anticipated and the demand for this continues.

Specifically, the tooth to attach the bracket for orthodontic teeth, including the incisor and the canine, each of the upper and lower jaw each six or more, after the operation of attaching the bracket to each of the teeth first In order to bind the wire made of rigid material to the fixing structure of the bracket, it is necessary to bind the wire with much thinner wire. This work needs to be done with sophistication, so it requires careful attention and effort for each tooth and takes relatively long time. This was an inherent difficult and difficult process for both physicians and patients.

Applicant has filed an improved "self-ligating orthodontic lingual bracket" with the same as the present application to solve this problem, in the patent application, the base portion formed with a ligation surface to bind to the lingual surface of each tooth, and One-touch orthodontic appliance including a fixing structure for fixing the wire for orthodontic wire and pushing the handle installed in the main body of the fixing structure so that the cover is opened automatically and the orthodontic wire wire can be detached. A lingual lingual ligation bracket is disclosed. In particular, the present invention is used in combination with the one-touch orthodontic lingual ligation bracket to maximize the work efficiency of the orthodontic process.

Indeed, according to the dental technique for orthodontics, a model of an orthodontist is first modeled using a model of an orthodontist's orthodontic state, and then, based on this, an ideal orthodontic form after treatment and correction is produced. The actual orthodontic process is undertaken through the steps of the auxiliary devices for correcting the teeth, that is, the position on the tooth surface to which the bracket is to be bonded and the arrangement of the wire wire.

In lingual orthodontic treatment, the exact position of the brackets has a great influence on the treatment result. Therefore, after the bracket is attached to the ideal position of the dental model, the bracket is attached to the ideal position of the dental model rather than the direct bonding technique. The indirect adhesive technique that moves the position back to the actual tooth is mainly used.

In the process of attaching the lingual bracket to the tooth model, until now, each of the brackets is ligated to the orthodontic wire made for each patient and then attached to the tooth model at once. Although it is possible to maintain the arch form, problems such as the vertical position of the bracket deformed or the left and right heights are changed by the elasticity of the orthodontic wire.

In addition, when using a method of attaching brackets to a tooth model by inserting a few brackets into a fan-cut metal plate, the height of the individual brackets can be more stably positioned than that of the orthodontic wire. Because of the limited size and size, the shape of the dental arch of each patient could not be compensated for, so there was a high risk of incorrect positioning of the bracket. Especially in the indirect bonding technique, the entire brackets are arranged on the tooth model, and the shape of the corrective wire (ideal arch) is perfectly matched and used throughout the treatment period. If the bracket is attached separately, it is impossible to use this ideal line.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus capable of redesigning an ideal line shape after attaching a bracket while being able to attach to an ideal position according to the shape of an individual arch of an individual patient when attaching a lingual orthodontic bracket to a tooth model. will be.
