The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Referring to fig. 1, the present utility model discloses a multi-curved wire reed appliance for correcting anterior inverse jaw, comprising: anterior multi-curved wire 10, connection block 20, posterior jaw pad 30, interproximal hook 40, and transparent appliance 50.

Wherein the transparent appliance 50 is used to wrap the teeth of the posterior region. One end of the anterior multi-curved wire 10 is provided with a plurality of curved structures for releasing the pushing force of the anterior teeth and is abutted against the lingual side of the anterior teeth for pushing the anterior teeth to move forwards; the other end of the anterior multi-curved wire 10 is fixedly connected to the connecting block 20. One end of the adjacent-to-adjacent hook 40 is buckled at a wedge-shaped adjacent joint between two rear teeth, and the other end is fixedly connected with the connecting block 20 for hooking the rear teeth. The back dental pad 30 is provided on the maxillofacial surface of the patient's back teeth for elevating the upper teeth and opening the bite relationship.

The posterior segment cavity shape of the transparent appliance 50 and the shape of the posterior jaw pad 30 are matched so that the posterior jaw pad 30 can be received within the cavity of the posterior segment of the transparent appliance 50. When the transparent appliance 50 is worn, the transparent appliance 50 is wrapped on the posterior dental segment of the patient and compresses the posterior dental pad 30 against the maxillofacial aspect of the posterior teeth.

The posterior jaw pad 30 may take two forms:

referring to fig. 3a and 3b, the rear teeth jaw pad 30 may be a conjoined jaw pad 32, and the conjoined jaw pad 32 covers a plurality of rear teeth at the same time, so as to mainly play a supporting role, when the front teeth are pushed forward by the front teeth multi-curved wire 10, the rear teeth are subjected to a backward reaction force, and the conjoined jaw pad 32 connects the rear teeth together, thereby effectively enhancing the retention force of the rear teeth.

Referring to fig. 2a and 2b, the back teeth pad 30 may be a single jaw pad 31, and the single jaw pad 31 covers only one back tooth; during the course of the appliance, certain treatment requirements may require posterior teeth movement, and the single jaw pad 31 may avoid teeth that need to be moved while also serving to open the bite.

When it is required to fix a single tooth, generally, the single jaw pad 31 is bonded to the tooth surface by using glass ions or other adhesives, and is a fixed and bonded structure to ensure the fixing force; of course, a removable structure may be used. When the teeth are to be retained simultaneously, if the conjoined jaw pad 32 adopts an adhesive structure, the adhesive is easy to overflow into the slits of the teeth, and discomfort is brought to the patient, so that the conjoined jaw pad 32 generally adopts a removable structure, that is, the conjoined jaw pad 32 is suitable for matching with the teeth with respect to the mounting surface of the teeth, and the conjoined jaw pad 32 can be buckled on the teeth.

The reed correcting device can be matched with a transparent correcting device for use. (1) The acting force released by the curved structure on the anterior multi-curved wire 10 pushes the anterior to the front, and the pushing force of the anterior can be adjusted by adjusting the quantity and the size of the curved structure; the plurality of front teeth multi-curved wires 10 can effectively improve the forward moving efficiency of the front teeth; (2) The back teeth jaw pad 30 can be set as a single jaw pad 31 or a conjoined jaw pad 32 according to the treatment requirement of a patient, the conjoined jaw pad 32 covers a plurality of back teeth at the same time, when the front teeth are pushed forward by the front teeth multi-curved wire 10, the back teeth can be subjected to a backward acting force, and the conjoined jaw pad 32 connects the plurality of back teeth together, so that the retention force of the back teeth is effectively enhanced; (3) The connection structure formed by the back tooth jaw pad 30, the adjacent hooks 40 and the transparent appliance 50 is fixed with the back teeth, the transparent appliance 50 wraps the back teeth, the adjacent hooks 40 are buckled at the adjacent points of the back teeth, so that the retention force of the back teeth and the appliance can be enhanced, the wearing is comfortable, and the fitting degree is high.

Preferably, the connection block 20 is a self-gel block or a 3D printing molded resin block, so that wearing comfort is ensured. Further preferably, the bottom shape of the self-gel block is matched with the mucosa of the maxillary top of the oral cavity, so that the self-gel block is stably worn, and referring to the schematic cooperation diagram of the self-gel block and the dental model 70 shown in fig. 5, specifically, the cross section of the self-gel block is matched with the cross section of the bottom surface of the oral cavity.

Preferably, the curvature of the single anterior multi-curvature wire 10 may abut on the lingual side of the single tooth for urging the single tooth to move forward; alternatively, the curvature of a single anterior multi-curvature wire 10 may simultaneously abut the lingual side of multiple teeth, thereby simultaneously pushing the multiple teeth forward.

In order to prevent excessive movement of the anterior teeth during pushing of the anterior teeth forward, the present utility model preferably also includes labial archwire 60; referring to fig. 4a and 4b, both ends of the labial archwire 60 are secured to the connection block 20 such that the labial archwire 60 fits around the labial side of the anterior tooth, thereby limiting excessive movement of the anterior tooth.

Preferably, the anterior multi-curved wire 10 is made of any one of stainless steel, beta-titanium alloy, nickel-titanium alloy, super-elastomer metal and high polymer material.

Similarly, the labial archwire 60 may be any one of stainless steel, beta titanium alloy, nickel titanium alloy, super-elastomer metal, and polymeric materials.

The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
