A comparative evaluation of midfacial soft tissue and nasal bone changes with two maxillary protraction protocols: Tooth-borne vs skeletal-anchored facemasks.

Objectives: Greater advancement of the maxilla can be achieved with skeletal-anchored facemasks (SAFM) using miniplates than with conventional tooth-borne facemasks (TBFM). The purpose of this study was to compare the effects of TBFM and SAFM on midfacial soft tissue and nasal bone up to two years after treatment.

Settings And Sample Population: Sixty-seven growing patients with Class III malocclusions were treated with facemasks.
