Orthodontic Treatment FAQs

What is Phase I (Interceptive Treatment) and Phase II treatment?

Orthodontic treatment sometimes consists of a two-part approach. Phase I or Interceptive Treatment usually starts while the child has most of their baby teeth and a few of their permanent incisors. This stage in development is usually about the age of 7. The goal of Phase I treatment is to intercept a moderate or severe orthodontic problem early in order to reduce or eliminate it. These problems include skeletal dysplasia, crossbites and crowding. Phase I treatment takes advantage of the early growth spurt and turns a difficult orthodontic problem into a more manageable one. This helps reduce the need for extractions or surgery and delivers better long-term results and treatment options. Most Phase I patients require a Phase II treatment in order to achieve an ideal bite.

Phase II treatment usually occurs a number of years later. Usually we are waiting for more permanent teeth to erupt before Phase II begins. This most commonly occurs between the ages of 10 and 16. The goal of Phase II treatment is to achieve an ideal occlusion with all of the permanent teeth.

Does everyone need a Phase I treatment?

Absolutely not! Only certain bites require early intervention. All others can wait until most if not all their permanent teeth erupt.

Can I wait on Phase I/Interceptive Orthodontic Treatment until my child is older?

This is not recommended. If your child needs Phase I treatment this usually means that he has a difficult problem that requires attention while the patient is young and still has primary teeth. If no orthodontic action is taken, treatment options may become limited, more difficult, and the long-term stability may be compromised. In addition, it may lead to extractions, oral surgery and increased costs.

What is Full or Comprehensive Orthodontic Treatment?

This is another name for orthodontic treatment in the permanent dentition at any age.

What is the length or duration of orthodontic treatment?

Braces may be on between 6 and 30 months, or longer depending on the age of the patient, the severity of the problem, the patient's cooperation, and the degree of movement possible.

What are extraction and non-extraction therapy?

Extraction therapy is a technique where some teeth are removed. Extractions are sometimes required to increase stability, prevent periodontal or gum problems, and resolve crowding.

This is in contrast to non-extraction therapy where all the teeth remain in the arch and are aligned properly. However, it is often necessary to reshape some of the teeth to achieve proper occlusion even though no teeth are removed.
