Abstract

The Alt-RAMEC protocol was introduced by Liou in the year 2005. It allows for sutural mobilisation by opening and closing the RME screw for 7-9 weeks. Maxillary protraction after the use of Alt-RAMEC (Alternate Rapid Maxillary Expansion and Contraction) protocol is an efficient method for early treatment skeletal Class III malocclusion. This case report shows the results of the using hyrax bonded maxillary expander with Alt-RAMEC protocol to treat a maxillary hypoplasia Class III malocclusion. A 10-year-old patient with skeletal class III malocclusion with anterior as well as unilateral posterior crossbite was treated using this protocol. CBCT scans were taken before and after expansion. These CBCT scans were used for assessing and analyzing the airway tissue changes that have occurred after using Alt-RAMEC protocol. The objective of this case report is to assess airway changes after using Alt-RAMEC protocol.
