RESUMEN

Changes in the midpalatal suture and the alterations in intercanine and intermolar widths with the use of the quad-helix appliance were evaluated. Study casts and occlusal radiographs from 10 patients with a mean age of 4 years and 10 months (SD 11 months) were analyzed. A statistically significant palatal suture widening was observed in all cases. The proportion of dental tipping accomplished with the treatment was greater than opening of the suture.
