Learning Objectives

The course aims at teaching the principles of orthodontic diagnosis, clinical examination and treatment planning.

1) to teach to the students the craniofacial growth; the discrepancies of maxillary and mandibular bone on the three space planes; the cephalometric analysis, examination of the space analysis in order to provide a correct orthodontic diagnosis of dento-skeletal pathologies of craniofacial complex (to distinguish I class from the II and from the III); identify asymmetry, impacted teeth, dental agenesis, dental overcrowding).

2) To know which are braces and orthopedic implants and how they act in the oral cavity.
