INTRODUCTION: The correction of Class II division1 malocclusion in patients with hyperdivergent growthpattern and mandibular retrognathism requires a differentapproach from the traditional treatment, which usually doesnot provide good results. OBJECTIVE: This article presentsa case report to illustrate an alternative protocol to correctthis type of dentofacial deformity, using the associationof miniscrews to restrain the maxillary vertical growthand a mandibular advancement appliance, to...

INTRODUCTION: Dental anomalies are challenges thatorthodontists may have to face when treating severalpatients. Supernumerary teeth, which represent about8-9% of all anomalies, do not seem to be associated withother shape, structure, size or position abnormalities.They have genetic-environmental causes, but may alsoresult from a hyperactive dental lamina, affecting onlyone tooth or, when more than one, usually associatedwith cleidocranial dysostosis, Gardner syndrome or cleftlip and palate....

OBJECTIVE: The aim of this study was to compare thecephalometric changes associated with the compensatorytreatment of skeletal Class III malocclusionpatients treatedwith anterior maxillary and mandibular torque alterations.METHODS: The sample consisted of 72 lateral cephalogramsof 36 patients treated with Class III Biofunctional brackets,with programmed modified torque on the maxillary (centraland lateral: 0o) and mandibular (central and lateral: +10o)incisors, with a mean age of 22.9 years...

OBJECTIVE: To present a checklist of conducts to preventtooth resorption in orthodontic treatment, sincethey are predictable. RESULT: The list of 20 predictivefactors presented will help to avoid or control toothresorption in orthodontic clinical cases, and data mustbe collected and analyzed right from the patient’s firstconsultation, even without the documentation composedof the complementary exams. CONCLUSION:In these cases, and situations with full informationand knowledge, the...
