Two-phase orthodontic treatment is a process that involves two separate courses of orthodontic treatment. The first phase, or early treatment, is typically started before all of the permanent teeth have erupted. This phase is designed to address any skeletal or developmental issues that may be present, such as a misaligned jaw or crowded teeth. The goal of early treatment is to create an environment that is conducive to healthy growth and development of the jaws and teeth.
The second phase of treatment usually begins once all of the permanent teeth have erupted. This phase is designed to correct any remaining dental or skeletal issues and achieve the final desired bite and aesthetic result. By starting treatment early, two-phase orthodontic treatment can often achieve better and more stable long-term results than a single-phase approach. It can also reduce the need for more invasive and extensive treatment later in life.
