Early class III facemask treatment with the hybrid hyrax and Alt-RAMEC protocol.

Abstract

The combination of the Hybrid Hyrax, facemask, and Alt-RAMEC protocol offers the following advantages in early treatment of severe Class III cases:
\n• Because the sagittal forces are transferred to the maxillary bone, there are no dental side effects in terms of mesial migration.
\n• The transverse forces are applied anteriorly to mini-implants, with no risk of periodontal damage to the premolars or deciduous molars.
\n• Due to the opening of the midpalatal sutures, Alt-RAMEC provides a longer-lasting "RPE effect" for increased maxillary protraction.
\n• The treatment is minimally invasive.
\n• The upper and lower arches remain fully accessible for orthodontic corrections.
