2. MAXILLAR HYPOPLASIA Rapid maxillary expansion (REP) is able to eliminate a transverse discrepancy between the dental arches due to maxillary constriction Treatment-induced widening of the maxilla leads to the correction of posterior crossbites, coordination of the maxillary and mandibular dental arches prior to orthopedic or functional treatment of Class II and Class III malocclusions

CONCLUSIONS ◗ poserior crossbite (mono or bilateral); ◗ corwding in the upper anterior teeth (incisive); ◗ correction of the postural mandibular asymetry ◗ Light autoexpansion of the lower anterior teeth (max 2-3mm) Remember : The expansion cannot change an extractive case in one non-extractive
