Abstract

The utility model relates to an invisible appliance for opening deep covering, which comprises a tooth socket, wherein the tooth socket comprises a front tooth part coated on front teeth and tooth grinding parts coated on rear teeth on two sides, a retainer is arranged in the tooth socket of the tooth grinding parts, and the tooth socket has reverse curvature opposite to the curvature of a tooth row to be corrected in the vertical direction. According to the utility model, the curvature of the tooth socket in the vertical direction is changed, so that the tooth socket has reverse curvature, the tooth part fastened on the rear tooth is utilized to provide anchorage for the depression movement of the front tooth, the front tooth is forced to be depressed and then the tooth is stretched, and the two are synchronously and coordinately carried out, the problem that the existing tooth socket has no vertical correction force, the vertical correction force can be generated only by relying on the occlusion state of the tooth, and the deep covering correction efficiency is low is solved.

Claims (6)

  1. 1. The invisible appliance for opening deep covering comprises a tooth socket, wherein the tooth socket comprises a front tooth part coated on front teeth and tooth grinding parts coated on rear teeth on two sides, and the invisible appliance is characterized in that a retainer is arranged in the tooth socket of the tooth grinding parts, and the tooth socket is provided with reverse curvature opposite to the curvature of a tooth row to be corrected in the vertical direction.
  2. 2. The deep opening and closing invisible appliance of claim 1, wherein the tooth socket is hollow in all or part of the position corresponding to the occlusal surface of the tooth, so that the occlusal surface of the tooth is exposed, and the tooth socket can be worn by a patient when eating conveniently.
  3. 3. The open-deep-covering invisible appliance as set forth in claim 1, wherein curvature reinforcing wires for reinforcing and maintaining curvature of the dental mouthpiece are provided in the dental mouthpiece in a direction from the posterior molar to the anterior molar.
  4. 4. The open-deep-covering invisible appliance of claim 3, wherein the curvature reinforcing wires are disposed on the lingual side of the shell.
  5. 5. The open-deep-covering invisible appliance as set forth in claim 3, wherein said curvature reinforcing wires are connected to retainers provided in the molar portion of the shell to form an integral force-transmitting structure.
  6. 6. The open-deep-covering invisible appliance as set forth in claim 5, wherein the curvature reinforcement wire and the retainer are bent from an elastic wire.

Description

Invisible appliance for opening deep covering Technical Field The utility model relates to the technical field of bracket-free invisible correction, in particular to an open deep covering invisible correction device. Background Deep occlusion is a misjaw deformity caused by vertical development abnormalities of the maxillary and mandibular arches and/or the maxillary and mandibular bones. The occlusion of normal teeth is such that the upper front tooth cover is not more than 1/3 of the length of the lower front tooth crown. The deep coating is that the cutting edge of the upper front teeth covers more than 1/3 of the length of the lower front teeth crown or the lower front teeth are engaged with more than 1/3 of the lingual side of the upper front teeth. Deep covering can not only affect oral health, but also affect facial aesthetics. The deep covering can force the mandible to be in the rear position, the joint pain, the elastic sound and other symptoms are easy to cause due to the fact that the temporomandibular joint is subjected to pressure increase, excessive tooth abrasion is caused by the fact that the upper tooth occlusion distance and the lower tooth occlusion distance are increased, excessive growth of masticatory muscles is stimulated, teeth are excessively abraded, teeth ache and sensitivity are caused, and other problems are caused, in addition, some people can bite the upper gingiva of the people frequently to cause occlusion wounds, and (2) the situation that the lower half of the face is too short, the lower jaw is retracted backwards and the chin is too short is caused due to too deep tooth occlusion, so that the facial proportion is inconsistent, and the facial appearance is influenced. In the field of orthodontic medicine, effective anterior occlusion opening has been the major and difficult point of orthodontic treatment for deep occlusion. In recent years, the implantation positions and the use modes of the micro-screw implants are different, and most of the micro-screw implants are implanted between the front tooth roots of the upper jaw and in the tip area, and the micro-screw implants and the upper front tooth bracket are connected through a rubber chain. Therefore, a more comfortable and safe method is also sought in recent years clinically to solve the problem. The Chinese patent publication No. CN212679293U discloses an adjustable invisible appliance, wherein the adjustable device is formed by upper and lower jaw occlusion, for patients with partial occlusion, reverse occlusion and deep occlusion, the patient is guided to occlude to an ideal occlusion position, namely a target position, after the patient occludes to the ideal occlusion position, the jawbone can reach the new occlusion position, muscles, ligaments and condyloid processes of an occlusion system can be rebuilt, the backward, sideways or forward positioning of the jawbone is realized, the adjustable device is formed, the formed adjustable device is combined with a bracket-free invisible appliance body to have a stable occlusion relationship, and because the adjustable device is operated according to the actual occlusion relationship of each patient, the formed appliance can more meet the actual requirement of the patient, so that the patient has a stable and repeatable occlusion relationship, the tooth alignment and jawbone positioning can be simultaneously carried out, the period of orthodontic treatment is short, and the user experience is better. However, the correction force of the position-adjustable invisible appliance is generated after the force formed by the occlusion of the upper jaw and the lower jaw acts on the invisible appliance, and the generation of the correction force has stronger dependence on the occlusion state of teeth. The Chinese patent publication No. CN213607025U discloses an orthodontic device for depressing anterior teeth and guiding mandibles forwards, which comprises an invisible appliance, wherein a cavitation inclined surface guide plate is arranged in the anterior tooth area of the lingual side of the upper jaw of the invisible appliance, the cavitation inclined surface guide plate is of a crescent structure, and the height of the cavitation inclined surface guide plate is suitable for the height of a dentition plane. The structure and the invisible appliance are integrated, the function of guiding the mandible to move forwards is increased by utilizing the cavitation inclined guide plate, the functions of pressing the anterior teeth and lifting the posterior teeth by the plane guide plate are integrated, and the effect of correcting the mandibular postcontraction case is achieved by replacing the invisible appliance every week, so that the symptoms of deep covering, mandibular postcontraction and the like in the misjaw deformity are solved. The correcting force of the orthodontic device for depressing the anterior teeth and guiding the anterior mandible is also generated by the acting
