Description

Invisible appliance without bracket

Technical Field

The utility model relates to an orthodontic technical field, concretely relates to ware is rescued to no support groove stealthy mainly is applied to and can forms local interlock pressure zone in just abnormal treatment, strengthens the efficiency that the ware was pressed down the tooth stealthy.

Background

The bracket-free invisible appliance is favored by patients due to attractive appearance, comfort and convenience for oral hygiene maintenance, and more patients select the bracket-free invisible appliance to replace the traditional fixed appliance for orthodontic treatment. The bracket-free invisible orthodontic technology enables a patient to wear a tooth socket and then control the tooth to move according to a virtual design target so as to realize an orthodontic target by acquiring a digital tooth model of the patient, a computer-aided design tooth movement scheme and computer-aided manufacturing of a series of invisible tooth sockets.

However, previous research reports show that the actual tooth movement of the patient after wearing the mouthpiece is different from the virtual design movement. For example, the anterior teeth often appear deep-covered due to insufficient vertical depression

The invisible appliance used at present adds the bite ramp design on the lingual side of the upper anterior facing, is similar to the flat guide in the traditional fixed appliance, and depends on the occlusal force to assist in depressing the anterior teeth and/or extending the posterior teeth, thereby opening the occlusion vertically. However, the placement of the bite ramp is affected by the front tooth coverage, and when the front tooth coverage is larger, the lower front tooth still cannot bite onto the bite ramp, thus not playing the role of assisting in depressing the teeth. In addition, for other teeth that need to be depressed alone, such as elongated posterior teeth, it is difficult to achieve better depression efficiency by relying only on the anchorage of the adjacent teeth and the deformation force of the mouthpiece.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a bracket-free invisible appliance for assisting the depressing of teeth. After the invisible orthodontic appliance is worn in the mouth, the tooth socket is arranged at the incised end of the tooth or

The surface is provided with convex accessory vacuoles which form an occlusal pressure area with the teeth of the jaw, and the occlusal force can be transmitted to the teeth covered by the tooth socket, so that the teeth are pressed down by the aid of the occlusal force. The design is applicable to any dental position where there is a jaw tooth, including anterior and posterior teeth, and is not limited by anterior tooth coverage.

In order to achieve the above purpose, the invisible orthodontic appliance provided by the utility model comprises a dental cast and a tooth socket covering the surface of the dental cast, wherein the cut end of the tooth on the dental cast or

The face is provided with the accessories, and the matched tooth socket is provided with accessory vacuoles.

Preferably, the dental model is a digital dental model or a resin dental model generated by 3D printing of the digital dental model.

Preferably, the attachments placed on the dental cast are round, rectangular or angular.

Preferably, the height of the accessory placed on the dental model is 0.25-2mm, and the width of the accessory is the tooth cutting end or

1/4-1/2 with long surface diameter.

Preferably, the accessories placed on the dental cast are not adhered in clinical operation, and accessory vacuoles are arranged between the tooth socket and the tooth at the corresponding position.

Detailed Description

The utility model is improved on the basis of the existing invisible appliance. The following description is made of specific examples of the invisible orthosis provided by the present invention to better illustrate the contents of the present invention, but the implementation method described herein does not limit the protection scope of the present invention.

The bracket-free invisible appliance of the utility model is characterized by comprising a dental cast (1) and a coverA mouthpiece (3) on the surface of the dental cast, the cut ends of the teeth on the dental cast or

The face is provided with an accessory (2), and an accessory vacuole is arranged on the tooth socket matched with the accessory.

It can be produced by the following method.

1. Firstly, a digitized three-dimensional dental model of the upper and lower jaws of a patient is obtained, and the obtained three-dimensional dental model is segmented to form an individual dental model. The tooth models are arranged according to orthodontic objectives to determine the target positions. The initial position and the target position of each tooth model are compared, and the movement between the two is decomposed into a plurality of stage positions according to the condition of a patient, so that a series of stage position tooth models are generated.

2. The position of any stage of the dental cast (1) can be selected, for example, at the incisal end of the anterior teeth in fig. 1 and 2 or at the posterior teeth in fig. 3 and 4

The surface is designed to place the accessory (2), and the accessory and the original dental model are integrated into a whole to generate a new dental model.

3. The upper teeth of the dental cast are cut or

The accessory placed on the surface is round, rectangular or angular, the height is 0.25-2.0mm, and the width is tooth cutting end or

1/4-1/2 with long surface diameter.

4. At the incisal end of the tooth or

The tooth mould with the accessory placed on the surface can be directly printed to produce the invisible tooth socket (3), or the resin tooth mould is firstly printed and then the invisible tooth socket is produced by a film pressing manufacturing method.

5. Designed to be placed at the cut end or

The attachment of the face is not clinically adhesive. After the produced tooth socket is worn in the mouth of a patient, accessory vacuoles are arranged between the tooth socket and teeth, and can form an occlusion pressure area with the teeth of the jaw to transmit occlusion force to the teeth covered by the tooth socket, so that the clinical effect of assisting in depressing the teeth is achieved.

The figures are only examples and the invention is not limited to the embodiments shown in the figures. Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
