Treating Class III malocclusion is a challenge for orthodontists. It is best to treat it at growing stage with dentofacial orthopedics. 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 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 (Alternate Rapid Maxillary Expansion and Contraction) protocol to treat a maxillary hypoplasia Class III malocclusion. A 12-year-old patient with skeletal class III malocclusion with anterior and unilateral posterior crossbite was treated using this protocol. CBCT scans were taken before and after expansion. These CBCT scans were used for assessing and analysing the soft tissue changes that have occurred after using Alt-Ramec protocol. The objective of this study is to assess soft tissue changes after using Alt- RAMEC protocol. Key-words: Alt-RAMEC (Alternate Rapid Maxillary Expansion and Contraction protocol), computed cone beam tomography (CBCT), skeletal Class III malocclusion, soft tissue changes.
