Abstract: One of many universal requirements of dental or orthopedic implants, wherever they are used in the vital body, is that the implant system should be biologically functioning. To achieve the biological functionality, the implant should meet several requirements for compatibility. These include biological compatibility and mechanical compatibility. It has now been recognized that morphological compatibility and crystallographic compatibility should be added to these two compatibility requirements. Hence, the present invention provides a method of forming a certain type of crystalline structure of titanium oxide and controlled surface roughness to meet both morphological and crystallographic compatibilities. It has been further determined that a chemical treatment (using sodium hydroxide) alone or followed by in-air oxidation, or acid treatment (a mixed aqueous solution of hydrofluoric acid and nitric acid), followed by sodium hydroxide treatment, furthermore followed by in-air oxidation provide for advantageous surface modifications to create a complex mixture of rutile with anatase and/or brookite types of titanium oxide and provide a most favorable surface for wettability and an acceptable range of surface roughness.

Abstract: Polymeric resin matrix phase (thermoplastic, thermosetting or biomass) is reinforced with fiber filament or fine particles to enhance the mechanical properties (particularly, bending strength and bending stiffness), impact strength while keeping its original transparency. Plastic brackets (either previously reinforced as mentioned above or un-reinforced) can be surface-treated by plasma coating with thin film or simply ultra violet radiation to enhance the surface mechanical properties as well as anti-frictional force against the archwire's movement while again maintaining its transparency. Accordingly, the present invention can provide orthodontic brackets made of plastics with high mechanical strengths and clearness, so that aesthetic appearance is improved.

Abstract: By using titanium, titanium based alloys, or related metals or alloys, an orthodontic bracket can be manufactured which is lighter and stronger than any conventional type of bracket made of stainless steels, plastics and even ceramics. Ti based brackets have shown excellent corrosion resistance and possess good biocompatibility. Surface treatments including nitriding, diamond coating, pre-oxidation or shot-peening on the slot bottom surface of such brackets reduce the friction coefficient against the orthodontic archwire. Furthermore, the bonding strength may be enhanced by shot-peening, ion beam etching or reactive ion etching on the tooth contact surface of the base portion of the bracket.
