The aim of this prospective study was to evaluate the midpalatal suture in children submitted to rapid palatal expansion with computerized tomography. The sample was comprised of 17 children aged between 5 years 2 months and 10 years 5 months. The tomographic images showed that, after the retention phase (8-9 months post-expansion), the midpalatal suture was completely ossified from the anterior to the posterior nasal spine region.  (Rev Esp Ortod. 2006;36(3):191-200)

Key words:
