Description

Orthodontic combined appliance and manufacturing method thereof Technical Field The invention relates to the technical field of orthodontic treatment, in particular to an orthodontic combined appliance and a manufacturing method thereof. Background Orthodontic treatment mainly adjusts coordination among facial bones, teeth and nerves and muscles of a maxillofacial region through various orthodontic devices, namely, adjusts abnormal relations among upper and lower jawbones, between upper and lower teeth, between teeth and jawbones and between nerves and muscles connecting the upper and lower teeth, and finally, an orthodontic treatment aim is to achieve balance, stability and beauty of an oromandibular system, and in the orthodontic treatment process, an orthodontic appliance is needed. The existing orthodontic appliance, namely a muscle function appliance, an occlusion inducer, a concealed appliance, a function appliance and a fixed appliance, can only provide a single correcting effect. Has slow curative effect and limited treatment range. Accordingly, there is a need to provide an orthodontic appliance and a method of making the same to address the above-mentioned problems. Disclosure of Invention In order to overcome the defects, the invention aims to provide the orthodontic combined appliance and the manufacturing method thereof, and simultaneously plays roles of the two appliances to synchronously correct teeth, so that the tooth correction efficiency is improved. In order to achieve the purpose, the technical scheme includes that the orthodontic combined appliance comprises an inner appliance and an outer appliance, wherein the inner appliance comprises an appliance contact surface which is contacted with the labial side of teeth to be corrected and an outer peripheral matching surface, the outer appliance comprises an inner side surface which faces the labial side of the teeth to be corrected, the inner appliance is coated with the outer appliance, the inner appliance is at least partially embedded into the outer appliance, and when the orthodontic combined appliance is worn, the inner side surface of the outer appliance is contacted with the outer peripheral matching surface on the inner appliance. Further, the inner appliance is a fixed appliance or a functional appliance, and the outer appliance is a stealth appliance or a silica gel appliance. Further, the size of the correction contact surface is matched with the labial tooth surface of the tooth to be corrected. When the inner appliance is a fixed appliance, the appliance contact surface is the surface of the bracket which is adhered to the tooth surface of the tooth, and the size of the appliance is matched with the tooth surface of the tooth so as to fix the bracket on the tooth surface of the tooth; when the inner appliance is a functional appliance, the appliance contact surface is the surface of the steel wire facing the teeth.
