Problems solved by technology

If the curvature of the tooth surface changes greatly, more adhesives are required, causing the base plate of the retainer to be far away from the tooth surface, making the patient feel uncomfortable and easy to loosen, which ultimately affects the retention effect
The other is an adhesive retainer made of twisted silk, but the clinical operation of this type of retainer is cumbersome, and the chair-side working time is long, and there may even be disadvantages such as retainer loosening and retention failure

Embodiment Construction

[0034] refer to figure 1 , the manufacturing method of personalized lingual orthodontic retainer, comprises the following steps:

[0035] (1) Take dental model;

[0036] (2) Convert the dental model into an STL model or a three-dimensional CAD model and store it in the computer;

[0037] (3) Import the STL model or 3D CAD model into the 3D CAD design software, take the arch wire plane, draw the CAD plane model of the arch wire shape on the plane according to the shape of the dental arch, and then design the personalized design according to the STL model or 3D CAD model The base plate of the retainer, and then design the retainer groove according to the drawn arch wire shape and direction, and finally obtain a complete retainer CAD model;

[0038] (4) Import the CAD model of the retainer into the wax-type machine to make the wax-type retainer;

[0039] (5) Precision casting the wax type of the retainer, and performing surface treatment on the cast retainer according to clini...

Abstract

The invention discloses a manufacturing method of an individualized tongue-side orthodontic retainer, comprising the following steps: taking a dental model; establishing a three-dimensional CAD model;drawing an arch wire flat surface and an arch wire, and designing a single retainer CAD structure model; guiding the single retainer CAD structure model into a fast wax pattern machine to obtain a retainer wax pattern; casting the retainer wax pattern, and obtaining the retainer after necessary surface processing; guiding a two-dimensional CAD model of the arch wire into a precise marking machineto obtain a pattern with the same shape and size with the arch wire; bending to obtain the arch wire according to the pattern, and welding the arch wire and the retainer together by a laser welding method; and then placing the retainer on the dental model to carry out integral vacuum film pressing to obtain a positioning pallet. The invention can realize the individualized production according toindividual demand; in addition, the prepared retainer is matched with a tooth shape, has high precision and lasting non-deformation, is suitable for being worn for a long time by patients and has thin thickness, good anchorage stability and convenient clinical operation. The manufacturing method is widely used for the production process of the orthodontic retainer.

Description

technical field [0001] The invention relates to a manufacturing technology of an orthodontic retainer for correcting teeth, in particular to a DLP digital image projection technology rapid prototyping manufacturing method of an individualized lingual orthodontic retainer. Background technique [0002] To align misaligned teeth, orthodontic techniques are widely used in clinical medicine. All patients after orthodontic treatment need to wear an orthodontic retainer to consolidate the treatment effect. It is an indispensable and important part of the orthodontic process. Wearing an orthodontic retainer is the most effective measure to prevent deformity recurrence. It is commonly used at this stage Orthodontic retainers can be divided into movable retainers and fixed retainers. Among them, the movable retainer hinders oral functions such as chewing and pronunciation, and some patients are unwilling to wear the movable retainer because of discomfort and inconvenience, which lea...
