Abstract
An orthodontic bracket includes a ceramic body having an elongated channel, and a metallic archwire slot liner that is received in the channel. The liner is affixed to the ceramic body by a brazing process using a brazing material such as platinum, silver, an active metal or a mixture of molybdenum and manganese. Alternatively, the liner is formed in situ in the bracket body.
