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.
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 all permanent teeth have erupted, and usually requires braces on all the teeth for an average of 24 months. Retainers are worn after this phase to ensure you retain your beautiful smile.
As mentioned earlier, the initial exam is performed at no charge. Fees for corrective appliances and services will be established at the time of consultation, prior to the initiation of treatment. The cost established for these procedures is generally much less than conventional orthodontic treatment. It is based on the type of appliance needed, the length of time of treatment and the intensity of treatment. Growth Guidance may not eliminate the need for standard orthodontics, such as braces, but it can save $200 - $1200 of those costs by ensuring a better growth pattern for the teeth and more stable results.
Two-phase orthodontic treatment is a very specialized process that encompasses tooth straightening and physical, facial changes. 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.
The disadvantage of waiting for complete eruption of permanent teeth and having only one phase of treatment for someone with a jaw discrepancy is facing the possibility of a compromised result that may not be stable.
The goal of first phase treatment is to develop the jaw size in order to accommodate all the permanent teeth and to relate the upper and lower jaws to each other. Children sometimes exhibit early signs of jaw problems as they grow and develop. An upper and lower jaw that is growing too much or not enough can be recognized at an early age. If children after age 6 are found to have this jaw discrepancy, they are candidates for early orthodontic treatment.
Because they are growing rapidly, children can benefit enormously from an early phase of orthodontic treatment utilizing appliances that direct the growth relationship of the upper and lower jaws. Thus, a good foundation can be established, providing adequate room for eruption of all permanent teeth. This early correction may prevent later removal of permanent teeth to correct overcrowding and/or surgical procedures to align the upper and lower jaws. Leaving such a condition untreated until all permanent teeth erupt could result in a jaw discrepancy too severe to achieve an ideal result with braces.
Orthodontic records will be necessary to determine the type of appliances to be used, the duration of treatment time, and the frequency of visits. Records consist of models of the teeth, x-rays, and photographs.
In this phase, the remaining permanent teeth are allowed to erupt. Retaining devices are not usually recommended since they may interfere with eruption. It is best to allow the existing permanent teeth some freedom of movement while final eruption of teeth occurs. A successful first phase will have created room for teeth to find an eruption path. Otherwise, they may become impacted or severely displaced.
In other words, at the end of the first phase of treatment, teeth are not in their final positions. This will be determined and accomplished in the second phase of treatment. Selective removal of certain primary (baby) teeth may be in the best interest of enhancing eruption during this resting phase. Therefore, periodic recall appointments for observation are necessary, usually on a six-month basis.
