OBJECTIVE The purpose of this study was to present, compare, and discuss the techniques for rapid maxillary expansion. CONCLUSIONS The isolated transverse maxillary deficiency can be treated either orthodontically or surgically with rapid palatal expansion. In children and adolescents, conventional orthodontic rapid maxillary expansion has been successful when used before sutural closure. On the other hand, in skeletally mature patients, the possibility of successful maxillary expansion decreases as sutures close and the resistance to mechanical forces increases. CONCLUSIONS The selection of an expansion technique depends on a number of factors. It is more likely to advocate surgery as the patient's age, transverse needs, or acceptance of the idea of surgery increases.
