Abstract:

Maxillary protraction facial mask (PFM) is a commonly employed technique for the early treatment of ma-xillary deficiency. Alternate rapid maxillary expansion and contraction (Alt-RAMEC) can effectively open and activate maxillary sutures. The potential synergistic effects of Alt-RAMEC on enhancing maxillary protraction have attracted considerable attention among clinicians. This study reviews the biological and biomechanical bases, device application, clinical effects, and potential risks of maxillary PFM combined with Alt-RAMEC for the treatment of skeletal Class Ⅲ malocclusion. This study offers valuable insights for the clinical implementation of this integrated technique.

Key words: skeletal Class Ⅲ malocclusion, maxillary protraction, alternate rapid maxillary expansions and constrictions
