Description

  The present invention relates to an orthodontic mucosal protective sheet used to prevent orthodontic appliances attached to teeth from damaging the lips, cheek mucosa, tongue and the like during orthodontic treatment.

  During orthodontic treatment, orthodontic appliances usually hurt the lips, buccal mucosa, tongue, etc., forming after and ulcers, which is very painful for the patient. In such a case, it is common to wear soft wax or clay-like silicone rubber, but these are problematic in that they are easy to drop off and do not look good.

  Here, in Patent Document 1 (Japanese Patent Laid-Open No. 3-12147), when an orthodontic bracket is mounted by attaching a natural color or protective color cover to a metal bracket body portion of the orthodontic bracket. It has been proposed to improve the appearance of. In addition, by attaching a protective color cover to the bracket body portion, the arch wire can be easily fixed to the bracket without ligating the individual bracket using a ligature wire or the like.

Japanese Patent Laid-Open No. 3-12147

  A conventional orthodontic bracket cover as described in Patent Document 1 has an archwire fixing function, and is attached to the bracket by a dentist so as not to be easily removed. Conventionally, no attention is paid to a cover that can be easily attached and detached by the patient, and no such cover has been proposed.

  On the other hand, as indicated by arrows in FIG. 4, during the orthodontic treatment, not only the corners of the orthodontic bracket 20 but also the portion 30c of the arch wire 30 between the orthodontic brackets 20 cuts the mucous membrane with a blade. It can be hurt. Since this portion 30c is a portion that cannot be protected by soft wax or clay-like silicone rubber, when the portion in the oral cavity that hits such a portion 30c is damaged, the orthodontist attaches the vinyl protective tube 50 to the archwire. It is usual to protect through 30.

  However, in order to insert this tube 50, it is necessary for the orthodontist to perform, and the patient himself cannot use it according to the pain. Moreover, since the arch wire 30 must be removed from the orthodontic bracket 20 to insert the tube 50, the operation is complicated. Furthermore, since the tube 50 once attached remains attached until the next visit, there are many problems such as food residue and plaque remaining on the inner surface of the tube and being unclean. Conventionally, no attention has been paid to the problems caused by such archwires, and no measures for preventing them have been proposed.

  In view of these points, an object of the present invention is to propose an orthodontic mucosal protective sheet that can be easily attached to the patient and covers the orthodontic bracket and can be easily removed. It is in.

  Another object of the present invention is to propose an orthodontic mucosal protective sheet that can be easily attached to the orthodontic bracket and the archwire so that the patient can easily remove the orthodontic bracket and archwire. .

In order to solve the above problems, the orthodontic mucosa protective sheet of the present invention,
A sheet main body for covering the orthodontic bracket fixed to the tooth;
A wire attachment portion detachably attached to an arch wire passed through an arch wire slot of an orthodontic bracket;
The seat body has a smooth surface and is characterized in that a wire attachment portion is integrally formed on or attached to the back surface.

  The orthodontic mucosa protective sheet of the present invention is detachable from the orthodontic archwire. Therefore, it is not necessary for the dentist to attach and detach like the conventional archwire fixing cover, and the patient can attach and use it as necessary. In addition, unlike the case where the orthodontic bracket has a special structure and the cover is attached to the bracket, the sheet can be attached regardless of the type of the bracket to protect the mucous membrane from the bracket.

  Here, the wire attachment portion includes a plurality of protrusions arranged at predetermined intervals on the back surface of the sheet main body portion, a wire insertion hole formed in each protrusion, and an inner periphery of the wire insertion hole from the outer peripheral surface of each protrusion. It can be set as the structure provided with the notch for a wire fitting extended through to the surface.

  To attach the orthodontic mucosa protective sheet, place the sheet on the orthodontic bracket, position the notch of each protrusion on the wire attachment part on the arch wire, and push the sheet in this state. . When the wire attachment portion is snap-fit as described above, the attachment operation and the removal operation are simplified.

  Usually, two protrusions are formed on the back surface of the seat body so that the archwire portions drawn from both sides of the archwire slot of the orthodontic bracket are inserted into the wire insertion holes of the protrusions. In addition, the sheet may be attached to the archwire.

  Further, in the orthodontic mucosa protective sheet of the present invention, for covering a part of the portion of the arch wire drawn from the arch wire slot of the orthodontic bracket on one side or both sides of the sheet main body portion. It is desirable that the wire blinding sheet portion is integrally formed.

  When the orthodontic mucosa protective sheet having this configuration is attached to the archwire of the orthodontic bracket, the portion of the archwire exposed from the archwire slot can be covered by the archwire blindfolding sheet portion. . Thereby, the mucous membrane can be protected from the archwire.

  Here, from the viewpoint of appearance or the like, the surface color of the sheet main body may be set to be similar to the crown color. In addition, fashionability can be imparted by printing a predetermined pattern or information on the surface of the sheet main body. For example, fashionability can be imparted by making the seat body portion colored red or blue, or by arranging alphabets or illustrations.

  The orthodontic mucosa protective sheet of the present invention is detachably attached to the arch wire so as to protect the mucosa from the orthodontic bracket and the arch wire. Unlike the case of attaching to the bracket, it can be easily attached and detached by the patient himself, which is very convenient.
