Problems solved by technology

Clear aligners without brackets have the advantages of aesthetics and comfort. However, the orthodontic effect of treating overbite is weak, and the course of treatment required for open occlusion is longer than that of fixed orthodontics. Especially for cases with severe overbite, tooth dislocation and overbite often occur. Insufficient opening volume, resulting in frequent restarts and even failure of treatment
The existing technology combines invisible braces and fixed appliances to improve the efficiency of opening the front teeth, but it still has the following defects: 1. The appliance is equipped with brackets and auxiliary springs, and the comfort is poor; 2. The appliance is in place. It needs to be carried out step by step. The patient needs to place the braces and the auxiliary spring by himself when taking and wearing the appliance several times a day. The operation is difficult, it is difficult to ensure the accuracy and safety of the operation, and the controllability of the treatment is poor.

Embodiment 1

[0035] In this embodiment, an invisible appliance according to the present invention, such as Figure 1(1) - Figure 1(3) As shown, it includes cat-shaped auxiliary arch, auxiliary arch sheath, fixing slot, and retaining sleeve. The retention sleeve covers the maxillary dentition; the retention sleeve includes a front brace, a back brace, and a connecting bridge, the front brace covers the bilateral maxillary central incisors and lateral incisors, and the rear brace covers the bilateral maxillary first From the premolars to the first molars, the connecting bridge is a double band structure covering the labial and lingual sides of the canines on both sides. The auxiliary arch sheath is an inclined tubular structure, located on the buccal side of the bilateral posterior braces corresponding to the maxillary second premolars, and the auxiliary arch sheath forms an angle of 30°-60° with the maxillary occlusal plane.

[0036] In this embodiment, the cat-shaped auxiliary arch is in t...

Embodiment 2

[0041] Such as Figure 2(1)-Figure 2(3) As shown, the difference between the present embodiment and Example 1 is that the front brace covers the bilateral maxillary canines and incisors; the rear brace covers the bilateral maxillary second premolars and molars; the connecting bridge covers both sides The labial side and lingual side of the maxillary first premolar; the front braces form a pillow-like raised structure on the lingual side of the bilateral maxillary canines, which is a fixed groove; the cat-shaped auxiliary arch is B-shaped, and the cat-shaped auxiliary arch The cat-ear-shaped bow of B-type spans the interproximal space between the canines and the first premolars; the anterior braces set a buffer space corresponding to the incisal end of the incisors, which is suitable for canceling or reducing the incision when only the canines are depressed tooth depression.

Embodiment 3

[0043] In this embodiment, an invisible appliance according to the present invention includes a cat-shaped auxiliary arch, an auxiliary arch sheath, a fixing groove, and a retaining sleeve. The retainer covers the mandibular dentition; the retainer includes a front brace, a back brace, and a connecting bridge. From the premolars to the first molars, the connecting bridge is a double strip structure covering the labial and lingual sides of the mandibular canines. The buccal side of the posterior braces corresponding to the bilateral mandibular second premolars forms an inclined sheath-like structure, which is an auxiliary arch sheath, and the auxiliary arch sheath forms an angle of 30°-60° with the mandibular occlusal plane.

[0044] In this embodiment, the cat-shaped auxiliary arch is in the form of a dental arch, made of stainless steel wire, and has an A-shaped structure, with two cat-ear-shaped bends in the front section; the cat-ear-shaped bend spans the gap between the la...

Abstract

The invention provides a cat-shaped auxiliary arch invisible correcting and curing appliance, including: a cat-shaped auxiliary arch, auxiliary arch sheaths, fixing grooves and retaining braces. All the components of the invisible correcting and curing appliance are located in the upper / lower jaw dentition. Force-applying components of the correcting and curing appliance in the front teeth-segmentare hidden in the lingual side of the teeth, and the retaining braces are transparent. The appliance is simple in structure, and the force-applying components are sustained and gentle in force by using the resilience force of the metal wire, so as to significantly improve the correcting and curing efficiency. By adjusting the inclination angles of the auxiliary arch sheaths, the magnitude of thevertical force produced by the cat-shaped auxiliary arch can be adjusted; by adjusting the position of the restriction rings on both sides, that is to say, by adjusting the length of the arch wire inthe proximal-middle segment of the bilateral restriction rings, the direction and magnitude of the sagittal force applied to the front teeth can be adjusted; by adjusting the position relation betweenthe fixing grooves and the front-tooth resistance center, the magnitude of the moment can be adjusted; and the appliance can effectively unfold front-tooth occlusion, correct deep bite, establish normal front-tooth overbite coverage, improve the function of occlusion and the beauty of oral and maxillofacial region.

Description

technical field [0001] The invention belongs to the technical field of stomatology, in particular to a cat-shaped auxiliary arch invisible appliance. Background technique [0002] Orthodontics corrects various malocclusions by making the teeth move physiologically. The goal of the treatment is to coordinate the occlusion of the teeth, coordinate the positional relationship between the teeth and the soft and hard tissues of the maxillofacial region, and improve the health of the orofacial region. , aesthetics and functionality. Anterior overbite is one of the main indicators of dental occlusion, and has an important relationship with occlusal establishment, jaw development, and facial aesthetics. The incisal margin of the upper anterior teeth covers more than 1 / 3 of the crown length of the lower anterior teeth, which is called overbite. . Overbite mainly manifests as elongation of the maxillary and / or mandibular anterior teeth, and the incisal edge of the mandibular anteri...
