In treating adult patients with anteroposterior deficient maxilla, the clinician had to decide between an intrusive surgical approach or a camouflage therapy to mask the Class III malocclusion. However, alternate rapid maxillary expansion and constriction (ALT-RAMEC) is the treatment of choice in younger patients.</p><p><strong>Methods: </strong>The 7-week ALT-RAMEC protocol was modified and combined with MARPE to evaluate its efficiency and its sutural and dentoskeletal advantages over conventional MARPE in young adults. Twenty-nine patients with transverse and anteroposterior maxillary deficiency (mean age of 21.3) were randomly assigned to two groups. The conventional group received MARPE with its conventional expansion rate (Control group), while the ALT-RAMEC group was treated with a combination of MARPE and the ALT-RAMEC modified protocol. The efficiency of expansion, circummaxillary sutural displacement, and dentoskeletal effects were assessed.

The dentoskeletal effects revealed that conventional MARPE produced a buccal molar tipping while ALT-RAMEC showed a more bodily movement of the anchor molars.</p><p><strong>Conclusion: </strong>The modified ALT-RAMEC technique is a promising protocol sufficient to expand the maxilla transversely without tipping the anchored teeth in young adult patients.
