Double-splint orthodontic appliance for improving III-type malocclusion

Abstract

The invention provides a double-splint orthodontic appliance for improving III-type malocclusion. The appliance comprises an upper splint adapted to the upper jaw and a lower splint adapted to the left and right sides of the lower jaw, wherein the inner side of the upper splint is provided with an upper base support adapted to the palate side of the upper jaw; the inner side of the upper base support is connected with a hyperbolic reed; the tail end of the hyperbolic reed is embedded into the upper base support; upper guide inclined surfaces which are inclined backwards are arranged on the left side and the right side of the front end of the upper splint; a rear tooth area and a canine tooth area of the upper splint are provided with upper fixing clamps for fixing the upper splint to the upper jaw teeth; the lower splint comprises a left lower splint and a right lower splint; lower guide inclined surfaces which are inclined backwards and can be correspondingly contacted and matched with the upper guide inclined surfaces are arranged in first premolar areas of the canine teeth of the left and right lower splints; hyperbolic labial arches matched with the anterior teeth on the labialside of the lower jaw are connected to the positions, close to the outer ends, of the left and right lower splints; and lower fixing clamps for fixing the left and right lower splints on the lower jaw teeth are arranged at the positions, close to the buccal sides, of the outer sides of the left and right lower splints. According to the double-splint orthodontic appliance, functional factors are effectively considered when the problem of III-type malocclusion is solved.

Description

Technical field [0001] The present invention relates to the field of oral medical devices, and in particular, there is a two-fitting coil correction for changing the III category. Background technique [0002] Hybrid malformation refers to the abnormalities of the teeth caused by the innate genetic factors or the reheasal environmental factors such as diseases, oral adverse habits, rectimanes, etc. during children's growth and development. The abnormality such as the shape of the maxillary size is abnormal. The Ani III Class III is a common molform deformed, mainly manifested as the adherent (the "flooring day"), and the mandibular development and the middle depression of the midst of jaws. At present, the method of correcting the Habito III category mainly includes early functional orthopedics, and the intensive orthodontic orthodontic orthodontic correction of the constant tendon column and the end of growth and development. Early correction mainly includes front traction, Fran...
