Embodiment 1

[0019] Such as figure 1 The CAD and CAM personalized base sandwich ceramic brackets shown in this embodiment are composed of personalized bracket bases that match the finished ceramic brackets and are fully fitted with the lip surface of the teeth and the bottom surface of the finished ceramic brackets. The thickness of the substrate is 0.4-0.6cm (depending on the material), and the ceramic adhesive 2 bonds the personalized bracket base 1 and the finished ceramic bracket 3 into one body. The thickness of agent 2 is controlled at 30-50 μm.

[0020] The production method is as follows:

[0021] Use the chairside 3D scanner to obtain the shape information of the labial surface of the tooth, with an accuracy of 0.02mm; apply CAD and CAM software to design a personalized labial bracket base according to the shape of the tooth surface, the size of the base matches the finished bracket, and the lip of the tooth The surface and the bottom surface of the bracket are completely fitted...

Embodiment 2

[0023] Such as figure 2 The CAD and CAM personalized base sandwich ceramic brackets shown in this embodiment are composed of personalized bracket bases that match the finished ceramic brackets and are fully fitted with the lingual surface of the teeth and the bottom surface of the finished ceramic brackets. The thickness of the substrate is 0.4-0.6cm (depending on the material), and the ceramic adhesive 2 bonds the personalized bracket base 1 and the finished ceramic bracket 3 into one body. The thickness of agent 2 is controlled at 30-50 μm.

[0024] The production method is as follows:

[0025] Use the scanner to obtain the shape information of the lingual surface of the teeth, and use CAD and CAM software to design the base of the lingual bracket. The base of the lingual bracket wraps around the middle and lower 2 / 3 of the lingual surface, increasing the contact area between the base and the tooth surface, increasing the The bonding strength between the base and the toot...

Abstract

The invention discloses a CAD and CAM personalized substrate sandwich ceramic bracket, which can increase the fit between the ceramic bracket as well as a tongue side bracket and the dental face, so the binding strength of the bracket and the dental face is increased. The CAD and CAM personalized substrate sandwich ceramic bracket consists of a personalized bracket base (1) which is matched with a finished ceramic bracket and completely jointed with the lip face or tongue face of a tooth body and the bottom face of the finished ceramic bracket, a binder (2) and the finished ceramic bracket (3), wherein the thickness of the substrate is 0.4 to 0.6 centimeters; the ceramic binder (2) binds the personalized bracket base (1) and the finished ceramic bracket (3) into a whole; and the thickness of the ceramic binder (2) is kept between 30 and 50 micrometers.

Description

technical field [0001] The invention relates to a bracket and a manufacturing method, in particular to a CAD and CAM personalized substrate sandwich ceramic bracket and a manufacturing method, which belong to the application field of biomedical materials. Background technique [0002] In recent years, dental beauty has developed rapidly, especially in orthodontic treatment. Patients often seek to improve their appearance. However, the requirements of patients for orthodontic treatment do not only stop at the aesthetic improvement after treatment, but also have higher and higher aesthetic requirements during the treatment process. The participation of adults has broken through the forbidden area of ​​orthodontic treatment for nearly a hundred years, and broadened the field of orthodontic treatment, but it has also produced a series of problems, one of which is that some adults, due to social, occupational, aesthetic and other reasons, Higher requirements are put forward for ...
