Embodiment 1

[0043] Application of a fixed twin-block appliance for depressing anterior teeth in the correction of misaligned teeth:

[0044] A fixed twin-block appliance for depressing anterior teeth, consisting of a maxillary appliance 1 and a mandibular appliance 2. The upper appliance 1 consists of a casting-type belt ring 101 of the upper jaw of the bilateral posterior teeth through the central maxillary rapid expansion arch connected with appliance 203, the bilateral posterior occlusal surfaces are composed of upper occlusal pads 202, and the lingual side of the anterior teeth is provided with a separate lingual arch 104, and the mandibular appliance 2 is looped through the center by the lower casting belt 201 of the bilateral posterior teeth. The lower rapid arch expander 203 is connected, the bilateral bicuspid occlusal surface is composed of the mandibular occlusal pad 202, and the No. 6 tooth position of the mandibular appliance is a cast belt ring with a buccal tube to match Mul...

Embodiment 2

[0047]Based on Example 1, children who are in the replacement dentition period usually choose the first permanent molars on the upper and lower sides of the upper and lower jaws because of the retention teeth, and the first and second deciduous molars on the upper and lower sides of the jaws are the retention teeth. At this time, the first permanent molars The root of the tooth has been basically developed, and the first and second deciduous molars have not yet started to be replaced. A fixed twin-block appliance is used to depress the anterior teeth. The use of multi-purpose bow 3 can provide better retention conditions, and at the same time, it has less side effects on the remaining teeth in the mouth, and the force is transmitted to the alveolar bone through the retention teeth, thereby remodeling.

Embodiment 3

[0049] Based on Example 1-2, a large number of gaps are provided after the upper and lower jaws are expanded, which provides a large amount of gaps for the eruption of inherited permanent teeth, and also provides a solution for adjusting the current problems such as uneven dentition and deep overbite. Gaps are more conducive to tooth replacement; malocclusions are mostly abnormalities in the three-dimensional direction of the upper and lower jaws, teeth, and soft tissues. The upper and lower jaws are provided with gaps after the bow is expanded using the present invention, and the gaps are used to depress the upper and lower front teeth to solve the vertical problem. The upper abnormality is more conducive to the correction of sagittal misalignment. At the same time, patients with crowded upper and lower dental arches usually have abnormal tongue positions. After the upper and lower jaws are expanded, the width of the dental arch increases, providing sufficient space for the ton...

Abstract

The invention discloses a fixed type low anterior tooth Tin-block appliance and a working principle thereof, and particularly relates to the technical field of medical instruments. The fixed type low anterior tooth Tin-block appliance and the working principle thereof comprise an upper jaw appliance and a lower jaw appliance, and is characterized in that the upper jaw appliance is formed by connecting upper jaw cast belt rings of rear teeth on the two sides through a central upper jaw rapid expansion device, the rear tooth occlusal surfaces on the two sides are formed by upper occlusal pads, a split-type lingual arch is arranged on the lingual side of anterior teeth, the upper jaw occlusal pad and the lower jaw occlusal pad form blocking surfaces in the mesio-middle part of the upper occlusal pad and the far-middle part of the lower jaw occlusal pad so as to maintain anterior leading of the lower jaw, anterior teeth of the upper jaw and the lower jaw are depressed while the lower jaw is guided forwards, good occlusion can be formed after correction is finished, and the side effect that posterior teeth extend is avoided. Meanwhile, the appliance is matched with the multi-purpose bow, correcting in the three-dimensional direction is achieved from transverse expansion, vertical multipurpose arch and sagittal lower jaw guiding forward, the design is reasonable, and the correcting effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixed twin-block appliance for depressing anterior teeth and its working principle. Background technique [0002] The appliance can generate force, or use the appliance to change the deformed frontal bone and misplaced teeth by the periodontal support tissue through the functional force of the masticatory muscles and perioral muscles, so as to facilitate the normal growth and development of the maxillofacial surface. The traditional Twin-block appliance is a movable appliance, and the maxillary and maxillary splints lock the front and back of the retracted mandible. [0003] Problems with traditional Twin-block aligners: [0004] 1. The traditional Twin-block appliance is not designed to depress the upper and lower anterior teeth. After the treatment, the occlusal state of the anterior teeth in early contact with the rear teeth will appear. Long-term early contact of t...
