Embodiment 1

[0021] Such as Figure 1-4 As shown, a kind of orthodontist for preventing food impaction provided by the present invention comprises a base film 6 and a surface film which are pressed together with the shape of the jawbone and the teeth on the dental model 1, and the base film 6 and the surface film A correction steel wire skeleton is arranged between the films, and the correction steel wire skeleton is provided with a blocking steel wire 9 at a position corresponding to the interdental position of the dental model 1, and the bottom film 6 and the surface film are made of soft and transparent materials , the correction steel wire skeleton includes an outer correction steel wire 7 arranged on the outside of the teeth and an inner correction steel wire 8 arranged on the inside of the teeth, the outer correction steel wire 7 and the inner correction steel wire 8 are arc-shaped, and the arc of the inner correction steel wire 8 The middle part of the shape is equipped with a wavy ...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that two external correction steel wires 7 are set up and down, and the patient wears the corrector provided by this embodiment, which can move the deformed teeth, close the gaps between the teeth, and perform powerful correction . This design can improve the stability and structural strength of the orthotic for preventing food impaction of the present invention.

Abstract

The invention relates to the technical field of oral medicine orthodontic correction and in particular relates to a correction appliance for preventing food impaction. The correction appliance for preventing food impaction comprises a basement membrane and a surface membrane which are made of soft transparent materials, are press-fit together and follow change of dental cast jaw and teeth patterning, wherein a correction steel wire frame is arranged between the basement membrane and the surface membrane, blocking steel wires are arranged at corresponding positions of the correction steel wire frame and crevices between teeth of a dental cast, the correction steel wire frame comprises outer correction steel wires arranged outside teeth and inner correction steel wires arranged inside the teeth, the outer correction steel wires and the inner correction steel wires are arc-shaped respectively, a wavy U-shaped bending following change of shape of front teeth is arranged at the middle part of the U-shaped bending of each inner correction steel wire, a plurality of blocking steel wires are arranged at crevices between mortar teeth on each inner correction steel wire, each blocking steel wire is arc-shaped or inverted U-shaped, and the two ends of each blocking steel wire are respectively fixedly connected on the outer correction steel wires and the inner correction steel wires. The correction appliance for preventing food impaction can prevent foreign matters from being clamped into the crevices between teeth and has high comfort degree and good treatment effect when put in the oral cavity.

Description

technical field [0001] The invention relates to the technical field of orthodontic correction in stomatology, in particular to an orthotic for preventing food impaction. Background technique [0002] In the prior art, the inventor’s utility model CN ​​204092222U discloses an upper and lower jaw interactive corrector, the corrector includes a dural brace, and the dural brace is provided with an orthopedic wire for the upper jaw and a steel wire for the lower jaw. The two ends of the orthopedic steel wire and the mandibular orthopedic steel wire are respectively embedded in the dural braces. The maxillary orthopedic steel wire and the mandibular orthopedic steel wire wrap around the outer sides of the upper and lower teeth respectively in a wavy shape. Inwardly sloped to guide the upper teeth to bite on the outside of the lower teeth. [0003] Because the existing removable aligners can not close the adjacent tooth gaps, i.e. interdental gaps, which easily cause oral gingivit...
