摘要： 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.

摘要： A dental examination mirror is provided. The dental examination mirror includes an examination unit having a planar base wall and a side wall projecting upwardly and outwardly from the base wall. The side wall includes an edge remote from the base wall. A mirror wall is sealingly secured to the edge of the side wall and is substantially parallel to the base wall. The surface of the mirror wall facing away from the base wall are reflective to permit observation of regions in an intraoral cavity. At least portions of the mirror wall enable transmission of light. A light source and a heat source are disposed in the examination unit between the base wall and mirror wall. Light from the light source will be transmitted through at least portions of the mirror wall to illuminate at least portions of the intraoral cavity without shining light toward the eyes of the dentist or patient. The heat source in the examination unit prevents fogging of the mirror.

摘要： 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.
