Two-phase orthodontic treatment consists of two separate times when a child receives orthodontic treatment. A first phase of treatment is done while the child still has many or most of their primary or “baby” teeth. A second phase takes place when the child has most or all of their permanent teeth. Braces may or may not be used during a first phase of treatment. A first phase of treatment might be initiated to prevent a problem from developing, intercept a developing problem and/or guide the growth of jaw bones that support the teeth (growth modification), where braces may or may not be used. This treatment will be timed to predictable stages of dental development to provide the greatest potential for improvement and correction of malocclusion (bad bite). A first phase of treatment can provide patients with physical benefits of a better bite and possibly the aesthetic benefit of a better smile. A second phase of treatment moves permanent teeth into their final position.
