Maxillary expansion is the main method to solve the problem of transverse maxillary hypoplasia in orthodontic patients. The clinical effect of maxillary expansion has already been proved. Scientific and Objective evaluation of its clinical effect is helpful for doctors to deepen their understanding of the mechanism of dental arch width deficiency, optimize the design and selection of clinical treatment, and improve the effectiveness and stability of maxillary expansion treatment. At present, there are many methods to evaluate the curative effect of maxillary expansion, and this paper reviews its evaluation methods and development direction.
