ORTHODONTIC : The Different Between Phase 1 And Phase 2 Orthodontic Treatment

Phase I, or early intervention treatment is limited orthodontic treatment (i.e. expander or partial braces) before all of the permanent teeth have erupted.

Such treatment can occur between the ages of 6 and 10.

This treatment is sometimes recommended to make more space for developing teeth, correction of crossbites, overbites, underbites, or harmful oral habits.

The goal of Phase I Treatment is to develop the child's jaws to make room for the future eruption of permanent teeth and to improve the relationship of the upper and lower jaws.

An upper or lower jaw that is growing too much or not enough can benefit from this early orthodontic treatment.

Phase II treatment is also called comprehensive treatment, because it involves full braces when all of the permanent teeth have erupted, usually between the ages of 11 and 13.

Due to the improvements made in Phase I Treatment, Phase II Treatment requires less patient participation (no headgear and less rubber bands), often eliminates extraction of permanent teeth and reduces the time spent in full braces.
