Problems solved by technology

[0004] In the process of orthodontic treatment, in order to get rid of bad tongue habits, the commonly used method in fixed orthodontics is the installation of fixed tongue spines. The tongue spines are welded to the metal belt ring and glued to the upper and lower incisors, and extend to the lower The lingual mucosa of the anterior teeth, while the position of the tongue thorn of the existing invisible appliance is the position corresponding to the lingual side of the lower anterior teeth and the crown. There is still a certain space between the tongue thorn and the sublingual area at this position, and some patients After wearing it, the tongue will be placed under these tongue spines in order to obtain a comfortable position. In this way, the appliance will lose the effect of correcting bad tongue habits, and even aggravate bad habits. In addition, this method has certain safety hazards. If the welding is not firm, it is easy to be swallowed after falling off, causing unexpected damage to the patient
[0005] In the field of invisible orthodontics, there is no effective structure for improving tongue habits. Therefore, it is important to study a design method and preparation method of a dental instrument that cooperates with invisible orthodontics to achieve tongue orthodontics.

Abstract

A design method and preparation method of a shell-shaped dental appliance, the design method comprising: obtaining a digital jaw model, designing a shell-shaped dental appliance body, and setting a tongue correction body. After the shell-shaped dental appliance obtained by the above method is worn on the teeth, it can improve bad habits of the tongue body. The preparation method includes: 3D printing a series of corresponding digital jaw models of the teeth gradually changing from the initial position to the target position based on the designed shell-shaped dental appliance, and then using hot pressing on the solid jaw model A shell-shaped dental appliance containing the shape of teeth is obtained by molding, and then cut along the gum line or adjacent to the gum line on the shell-shaped dental appliance containing the tooth shape to obtain a shell-shaped dental appliance capable of accommodating teeth or directly using 3D printing The preparation of shell-shaped dental appliances was carried out in the same way.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a design method and a preparation method of a shell-shaped dental appliance. Background technique [0002] Bad oral habits are one of the most common causes of malocclusion. According to the statistics of Beijing Medical University, they account for about 1 / 4 of the causes of various malocclusions. They are harmful and abnormal habits that occur in the oral environment. Oral bad habits as external stimuli, inhibit or strengthen the function of a certain part of the mouth and jaw, or produce a direct force on the part, so that the normal balance of biological forces is destroyed, thereby hindering the normal development of children's oral soft and hard tissues, causing tooth decay. Arch and alveolar bone morphology changes. Orthodontic correction measures must be taken to adjust oral muscle function for long-term bad oral habits that cause malocclusion. [0003] The normal tongue is...
