Description

Encircling type end-cutting guiding appliance

Technical Field

The utility model relates to an orthodontic appliance field specifically is an end direction is cut to formula of encircleing and is rescued ware.

Background

Deep occlusions refer to malposition (occlusal) of the upper and lower arches of the jaw and/or the upper and lower jaws due to dysplasia in the vertical direction, i.e., the incisal margin of the upper anterior teeth covers the crown of the lower anterior teeth by more than 1/3 or the lower anterior teeth bites on the lingual side 1/3 of the upper anterior teeth. Mandibular retraction is a malocclusion deformity of mandibular recession due to either hypoplasia of the mandible or a congenital lack of lower anterior teeth and inadequate function of the lateral pterygoid muscle. The appearance is mainly characterized in that the jaw chin is short, the face below 1/3 is short, the side surface looks like a bird's mouth, and the appearance is beautiful and the mental health is seriously influenced. The tooth problems not only affect the appearance, social interaction and occupational selection, but also affect the function, make speaking mouth unclean, biting things chewing powerless and the like, and simultaneously cause tartar accumulation, halitosis, decayed teeth, periodontal disease and the like most easily. Adult patients need to be treated by orthognathic surgery, and patients in growth and development stage can be treated by orthodontic treatment. However, the existing correction appliance is complex to wear and not easy to fix, or needs to be implanted by operation, is expensive, needs frequent stress application, increases the number of times of repeated diagnosis, and increases the possibility of foreign body sensation and mucosal infection. Patients and medical practitioners prefer to have a non-invasive, simple, easy to use, low cost device to address the problem.

Detailed Description

The invention will be described in further detail with reference to the following drawings and specific examples, which should not be construed as limiting the invention.

As shown in fig. 1 to 4, the encircling type cut end guiding appliance of the present embodiment includes an orthopedic portion 1 and a positioning portion 2, the encircling type cut end guiding appliance main body is in a U-shaped structure, the orthopedic portion 1 is located at the bottom of the U-shaped structure, and the positioning portion 2 is located at two sides of the U-shaped structure;

the orthopedic portion 1 comprises an upper anterior tooth positioning groove 101, a lower anterior tooth positioning groove 102 and a cut end guide surface 103, wherein the upper anterior tooth positioning groove 101 is arranged along the arc shape of the bottom of the U-shaped structure and is recessed downwards, the lower anterior tooth positioning groove 102 is arranged along the arc shape of the bottom of the U-shaped structure and is recessed upwards and is positioned on the inner side of the upper anterior tooth positioning groove, the cut end guide surface 103 is an inclined surface, the inclined surface is positioned on the inner side of the lower anterior tooth positioning groove 102 and is inclined towards the recessed direction of the lower anterior tooth positioning groove 102 along the connecting direction with the lower anterior tooth positioning groove 102, and preferably, the inclined angle of the cut end guide.

In this embodiment, the positioning portion 2 includes a supporting frame 201, an encircling positioning structure 202 and a positioning rod 203, the supporting frame 201 extends in an upward arc shape along an inner edge 204 of the U-shaped structure, and the supporting frame 201 is connected to the orthopedic portion 1 at the bottom of the U-shaped structure.

In this embodiment, the encircling positioning structures 202 extend from the outer sides of the two ends of the U-shaped structure, and extend forward in an arc shape to the two sides of the orthopedic part 1, and the ends extend to the upper side of the orthopedic part 1, and the supporting frame 201 has a sawtooth structure with matched tooth shapes along the outer edge 205 of the side surface of the U-shaped structure.

In this embodiment, the positioning rod 203 is bent upward to form an L shape after extending a length along the tooth tip of the saw-tooth structure of the supporting frame 201.

In this embodiment, the end of the encircling positioning structure 202 and the positioning rod 203 have a retaining structure, the retaining structure of the encircling positioning structure 202 is an annular structure formed by partially bending, and the retaining structure of the positioning rod 203 is a spherical structure with a diameter larger than that of the positioning rod. Is used for clamping the encircling type cutting end guide appliance on teeth and preventing a sharp structure from scratching the oral cavity. Further, in use, the encircling positioning structure 202 is fixed to the side of the tooth after passing over the posterior tooth; the positioning rod 203 extends out and extends along the tooth tip of the sawtooth structure of the support frame 201, bypasses the gap between the posterior teeth and is fixed on the side surface of the posterior teeth. Further, the encircling positioning structure 202 and the positioning rod 203 are made of elastic materials and can be tightened according to the requirements of different orthopedic periods.
