Temporary skeletal anchorage devices (TADs) have been used for 20 years in clinical orthodontics. Not only has it been widely used in sagittal and transverse correction, it has been applied to improve vertical dimension in adults as well .

For growing patients, Modified C-Palatal Plate(MCPP) has been proven to be effective for molar distalization with little side effects on the palatal soft tissue. MCPP showed significant skeletal and dental effects including molar distalization on the maxilla especially for noncompliant Class ll patients. Also, application of MCPP and facemask seems to be a suitable treatment modality for maxillary protraction due to its maximal skeletal effects, minimal dental side effects, and nonsurgical approach in dentoskeletal Class III patients.

TADs applied in conjunction with growth modification will open a new paradigm of a non-extraction and non-surgery treatment. The palatal approach involves a flapless procedure to insert a single plate that produces bilateral retraction, which in turn enables a non-surgery approach for skeletal Class II and III patients.

I would like to present several clinical MCPP cases with the average and maximum amount of distalization you can expect and the stability of distalization from non-extraction treatment. In addition, I will focus on growth control using TADs for skeletal Class II and III patients.
