Two-Phase Treatment

What is the advantage of two-phase orthodontic treatment?

Two-phase treatment consists of two separate stages of orthodontic treatment in growing children. The first phase (Phase I) is typically initiated when many of the child's primary or “baby” teeth are still present. The second phase (Phase II) usually occurs when most or all of the permanent teeth have erupted. Two-phase orthodontic treatment is a very specialized process that encompasses tooth straightening and physical, facial changes. When appropriate, the major advantage of a two-phase treatment is to maximize the opportunity to accomplish the ideal healthy, functional, esthetic result that will remain stable throughout your life.

What if I put off treatment?

When two-phase treatment is indicated, waiting for complete eruption of the permanent teeth and having only one phase of treatment increases the possibility of a compromised result that may be less stable. In addition, orthodontic treatment can take advantage of a child's growth to produce a more favorable result. Some problems that are effectively treated in growing children may require corrective surgery if delayed until after facial growth has ceased.

First Phase Treatment: Your foundation for a lifetime of beautiful teeth

The goal of first phase treatment is to improve the environment for the future eruption of your child's permanent teeth. Phase I treatment is designed to provide a physical benefit to patients by enabling them to bite or chew more effectively, establish a more ideal pattern for future growth and reduce the risk of injury to improperly positioned teeth. Limited braces and/or other appliances are commonly used during Phase I treatment. Most patients who undergo a first phase of treatment will also require a second phase of treatment later on. Following the completion of Phase I, patients are placed under observation until it is appropriate for the second phase of treatment. This period of supervision can span from a few months to a few years and may or may not involve the wearing of a retainer or other maintenance appliance.

Monitoring your teeth's progress

At the end of the first phase of treatment, teeth are unlikely to be in their final positions. This will be accomplished in the second phase of treatment when most or all of the permanent teeth are present. Selective removal of certain primary (baby) teeth may be in the best interest of enhancing eruption during the resting period between the first and second phases of treatment. Therefore, periodic recall appointments for observation are necessary and are usually scheduled every 4-6 months.

Second Phase Treatment: Stay healthy and look attractive

The goal of the second phase is to make sure each tooth has an exact location in the mouth where it is in harmony with the lips, cheeks, tongue, and other teeth. When this equilibrium is established, the teeth will function together properly and a beautiful and healthy smile will result.

Movement & Retention

At the beginning of the first phase, orthodontic records were made and a diagnosis and treatment plan established. Certain types of appliances were used in the first phase, as dictated by the problem. The second phase is initiated when most or all permanent teeth have erupted, and usually requires braces on all the teeth for an average of 18-24 months. Retainers are worn after this phase to ensure you retain your beautiful smile.
