title: Camouflage treatment of severe bialveolar protrusion in skeletal Class II using miniscrew anchorage.
abstract: The aim of this case report was to demonstrate the efficient use of miniscrew as anchorage in a 12-year-old male patient with skeletal and dental Class II and severe biprotrusion and lips procumbency. It was proposed a compensating orthodontic treatment with 4 premolar extraction and maximum anchorage. Since the patient abandoned treatment after one premolar extraction, loss of anchorage occurred and treatment plan was modified to maximize lower retraction with miniscrew anchorage and distalization of the upper arch using two methods: Class II elastics from lower miniscrews to the sliding jig and modified transpalatal arch using palatal miniscrew. The results showed a significant improvement of his facial appearance, lip protrusion and also dental esthetics and function. It was concluded that miniscrews can provide absolute anchorage for maximum anterior retraction in order to correct dentoalveolar biprotrusion in the presence of limited thickness alveolar bone.
