Treatment planning considerations for adult patients.

Orthodontic treatment planning depends on determining specific treatment objectives before beginning treatment. Selecting specific treatment objectives aids in the selection of appropriate mechanotherapy for the patient. In adult patients, this is particularly important. With the exception of orthognathic surgery, orthodontic treatment in adults must rely exclusively on tooth movement because no skeletal growth potential exists. Therefore, the orthodontic movements must be achieved with greater precision. Finally, the medical and dental histories of the adult patient may further increase the complexity of treatment. Coordinating orthodontic therapy with periodontists, restorative dentists, and other specialists is often necessary.
