Phase II Orthodontic Treatment

​

Phase II treatment typically refers to the orthodontic treatment that may follow a first (early) phase I treatment. This usually involves placing braces on both the upper and lower teeth, once all the adult or ‘permanent’ teeth have come in or ‘erupted.’

​

Phase I usually does not correct all tooth and bite-related problems, therefore a second phase of braces (phase II) is needed to finish aligning the teeth and bite.

When Phase I treatment has been successfully completed, however, this second orthodontic treatment phase (phase II) will be reduced significantly, reflecting the benefit of the phase I early correction.

​

In simple terms: Phase II orthodontic treatment is usually full upper and lower braces. It is the second part of two phases of orthodontic treatment, and that is where it derives its name.
