Invisible appliance without bracket

Technical Field

The utility model relates to an orthodontic technical field, concretely relates to ware is rescued to stealthy of no support groove mainly is applied to in just abnormal treatment mistake

The teeth can assist in breaking bad tongue habits or clenching lower lip habits.

Background

Bad habits and mistakes of oral cavity

The development of deformities is closely related. Poor tongue habits such as vomiting and swallowing will result in anterior teeth opening

Narrow arch, poor lip habits such as biting the lower lip, etc., lead to anterior processes in the upper teeth and deep coverage of the anterior teeth. In the traditional fixed correction, the bad tongue habit or the lower lip bite habit is usually corrected by combining the fixed tongue thorn or the movable tongue thorn. Error in assistance in breaking bad habits

Treatment of teeth and maintenance of stability during the post-treatment holding period are of great importance.

In recent years, the bracket-free invisible appliance is favored by patients due to beauty, 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. However, the bracket-free invisible appliance only covers the tooth surface and can correct the error only by moving the teeth

Malformation without breaking the function of bad habit of oral lip and tongue. Without breaking bad habits, a malocclusion

The deformity is difficult to correct to be normal, or even if the deformity is corrected to be normal, the curative effect is unstable, and the deformity is easy to relapse. Therefore, how to combine the existing bracket-free invisible appliance with a device for breaking bad habits, such as tongue pricks, and the like, is a problem to be solved.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a support groove-free invisible appliance for correcting bad tongue habits. After the invisible appliance is worn in the entrance, the tongue spines extend downwards and inwards to block the acting force of the tongue body extending forwards on the anterior teeth, so that the invisible appliance is hiddenCorrecting anterior teeth opening caused by tongue-spitting habit while correcting teeth movement of appliance

In addition, the clenching lip habit can be prevented, and the deep coverage of anterior teeth can be corrected in an auxiliary way.

In order to achieve the above object, the utility model provides a ware is rescued in stealthy including rescuring ware body, tongue thorn and connector, and the tongue thorn is located the tongue side of the anterior teeth district on the ware of rescuring to inwards stretch out downwards, rescure the ware body and pass through the connector with the tongue thorn and even be a whole.

Preferably, the appliance body is matched with the shape of the maxillary dentition.

Preferably, the tongue pricks extend downwards from the appliance body at a position 5-7mm away from the lingual surface of the upper anterior tooth and are bent inwards to adapt to the shape of the lingual body.

Preferably, the number of the tongue spines is 3-6, and the length of the tongue spines reaches the gingival margin of the jaw teeth.

Preferably, the connecting body portion of the tongue plug connected to the appliance body is an extension of the appliance body on the palatal side of the anterior dentition or the full dentition.

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 utility model discloses a ware is rescued in stealthy nothing support groove's characterized in that, including correcting ware body (1), tongue thorn (2) and connector (3), the tongue thorn is located the tongue side of correcting the ware upper front teeth district to inwards stretch out downwards, correct the ware body and pass through the connector with the tongue thorn and even be a whole.

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. The digital dental model can be directly printed to produce the invisible dental cast, or the resin dental model is firstly printed and then the invisible dental cast is produced by a film pressing manufacturing method.

2. Selecting an upper jaw invisible appliance, namely an appliance body, and extending a tongue thorn inwards and downwards from the appliance body at a position 5-7mm away from the lingual surface of the upper anterior teeth, wherein the tongue thorn is adapted to the form of the lingual body. The tongue spine and the appliance body are connected into a whole through the connector.

3. The tongue spines and the connectors are manufactured by the same method as the appliance body, firstly, the shape is designed on a digital dental model to generate the dental model containing the tongue spines, and then the dental model is directly printed for production, or firstly, a resin dental model is printed and then the dental model is produced by a compression molding method.

4. The number of the tongue pricks is 3-6, and the length of the tongue pricks reaches the gingival margin of the jaw teeth.

5. The connecting body part of the tongue spur connected with the appliance body is the extension of the appliance body on the lingual and palatal side of the anterior dentition or the complete dentition.

6. After the invisible appliance containing the tongue thorn is worn in the mouth of a patient, the tongue thorn can block the acting force of the tongue body stretching forward on the anterior teeth, thereby correcting the anterior teeth opening caused by the tongue spitting habit while the invisible appliance moves the teeth

In addition, the clenching lip habit can be prevented, and the deep coverage of anterior teeth can be corrected in an auxiliary way.

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.
