Ordinary bracket orthodontics is one of the most traditional and cheapest appliances. Traditional orthodontic fixed appliances use stainless steel brackets, which are widely used.
Imported metal brackets are smooth in surface, compact in size, durable, accurate in slotting and well-made, which is helpful to the perfect arrangement of teeth. The unique fillet treatment of the bracket edge reduces the adverse stimulation to the oral mucosa and is affordable.
Domestic metal brackets can achieve acceptable therapeutic effect and are cheap. Of course, there is a certain gap between them and imported products in terms of materials, groove accuracy, surface smoothness and taste, but their performance basically meets the requirements of use.
