RESUMO
Expansion of dental arches has been in practice for a long time and will be around for years to come. Correct diagnosis along with familiarity of the appliance to be used will enhance the results of orthodontic treatment. The NPE incorporates many of the functions that exist in several different appliances. It can be used for maxillary corrections, crossbites, distal rotation and expansion of molars, molar stabilization, auxiliary placement for habit correction, intrusion of molars, three-way Saggital with utility arch, as an aid in Class II correction retainer, etc. It can be used in primary dentition, mixed dentition, adult dentition, cleft palate patients, surgery cases, Class III cases, and TMJ cases. Most patients can benefit from the use of this one appliance. I will continue to use the NPE and possibly discover more uses for it as I work with it.
