The upper braces and the lower braces respectively include an inner soft layer and an outer hard layer. The inner soft layer is attached to the periphery of the tooth. The outer hard layer is laminated on the outer side of the inner soft layer. The chip is arranged on the outer side of the outer hard layer or arranged between the inner soft layer and the outer hard layer. A monitor for detecting the wearing time is arranged in the chip. In the present invention, the inner soft layer is additionally arranged in the outer hard layer. This structure has the following advantages: the improved braces is a double-layer structure and is soft inside and hard outside. The attachment between the inner soft layer and the tooth is better.
