Since its introduction, in 1860 by Angel, and reintroduction by Haas, in 1965, maxillary expansion became popular among orthodontists throughout the world. Maxillary expansion provides many orthopedic and orthodontic beneits to the patient, including: Maxillary harmony with other facial bones, space in the dental arch for accommodation of teeth, etc. However, despite their widespread acceptance and use, questions remain about the most efective method of activating the expander to promote the best results. To elucidate these questions, Chinese researchers1 developed a systematic literature review with the aim of comparing the efectiveness of fast and slow maxillary expansion. The results showed that the slow expansion is efective in expanding the maxilla, and the rapid is efective in expanding both the upper and lower dental arches. The authors note, however, that with the slow expansion it is possible to obtain further expansion in the molar area of the maxilla. The data found in this study are of great clinical importance, since, from its knowledge, orthodontists can choose the protocol that best its their patients, not based on personal preferences, but on scientiic evidence.
