Assessment of Treatment Phases of Class II Malocclusion Treatment

The orthodontic treatment is usually consistent of one or several phases. Early treatments in mixed dentition are also called Phase I or interceptive treatment. Our research has shown that Class II is the most frequent malocclusion among the Bulgarian children population. The aim of this survey is to assess the treatment protocols for this malocclusion. The analyses are made based on treated patients in the Faculty of Dental Medicine Sofia. The survey analysis includes 661 patients. They are divided in two groups. We develop five treatment protocols for treatment of Class II malocclusion.
