Most of pacients in mixed dentition, with some open bite degree and atypical deglutition, we notice that the upper dentoalveolar process is increasing to the vertical side. The BTP use on the upper molar in these situations, with the central arch, low enough to make some pressure on the tongue during the deglutition. This system has been aproved as a molar intrusion movement. Can be noticed as a result the restriction of dentoalveolar process grown to the vertical side, orthopedic and jaw axes rotation grown in the horizontal direction changings.

Keywords: Vertical control. Dentoalveolar process. Transpalatal arch. Intrusion. Class II maloclusion.
