Technical Field
With the improvement of living standard and cultural degree, people pay more and more attention to the appearance details of the people, and always hope to own regular, white and healthy teeth in one mouth in the process of laughing or talking. However, it is not always enough to count, and people who have eighths have irregular teeth due to poor living and eating habits, and thus need orthodontic treatment. The orthodontic industry has therefore developed very rapidly in the last 10 years. But the main orthodontic market uses metal orthopedic wires such as stainless steel wires, nickel titanium shape memory alloy wires, titanium alloy wires and the like. Due to the metal property of the metal wire, the metal smile phenomenon appears in the orthodontic treatment process, which not only affects the beauty, but also affects the physical and mental health of teenagers. The development of aesthetic orthopaedic wires has become a major approach to solving this problem. The currently developed fiber-reinforced organic resin transparent orthopedic thread has good aesthetic effect, but has the problem of great brittleness in clinic. The preparation of a "stealth" aesthetic coating on the surface of an orthopedic wire that approximates the color of the teeth is currently one of the most effective methods. Currently, aesthetic coatings such as epoxy, polytetrafluoroethylene, chromium carbide, metal rhodium, etc. are prepared on metal wires by various electrodeposition and dip coating techniques. Although these coatings have good aesthetic effects, the problems of weak bonding force, poor wear resistance, too thick or too thin coating, poor biocompatibility of the coating and the like still exist. Therefore, the invention provides a preparation method for forming the titanium dioxide reinforced organic silicon resin aesthetic coating on the surface of the metal wire by adopting a spraying technology, and the coating has the advantages of strong binding force, small friction coefficient, proper thickness, good biocompatibility and the like.
