Abstract
A process for making orthodontic assemblies such as brackets and buccal tubes which permits simultaneous heat treating of the assembly while brazing the assembly together. The process consists of assembling a plurality of aligned bases with caps and a brazing insert. The caps are then tack welded (temporarily fastened) to the bases to produce a strip of orthodontic assemblies which can be easily handled. The strips are then heat treated to a brazing temperature in a specified atmosphere. The individual orthodontic assemblies are either automatically separated during the heat treatment or may be easily separated by cutting after removal from the furnace. The bases and caps for the buccal tube assemblies are of a unique design which is readily adaptable to the multiple strip brazing process.
