Abstract
An orthodontic appliance for use in the mouth which includes an annealing process to provide a marking area. A laser is used to surface anneal an orthodontic appliance, such as an orthodontic bracket, for identification purposes and to withstand a number of recycling processes for sterilization purposes. The surface annealing process does not remelt the marking area and is an advantage over the prior art in that the marking area is not rough or weakened by remelting the structure.
