Who needs Phase I?

Phase I is for children (typically around 7-9 years old) with mixed dentition, meaning with mixed "baby" teeth and permanent teeth.  Baby teeth or "milk" teeth are layman terms whereas primary teeth and deciduous teeth are the technical terms. Many dentists consider the term deciduous as more correct than primary.  Permanent teeth is alsc called adult teeth.

Typical indications for Phase I are

• cross-bites (either anterior or posterior or both)
• crooked front teeth
• upper front teeth stick out
• psychological reason (e.g., for better self esteem, more confidence, etc.)

In many cases, if the condition is not treated in Phase I, it becomes so crowded when the permanent teeth erupt. then extraction of either 2 or 4 teeth becomes a must.

Treatment time for Phase I is approximatelly 12-16 months.

The following is an example of Phase I
