Title

5D treatment of Class II malocclusion

Abstract

Aim: to evaluate patient-related factors that potentially can improve the efficacy and efficiency of Class II treatment in the growing patient. Two such factors that possibly can improve the efficacy of treatment will be analyzed: 1) timing of treatment, the fourth dimension in diagnosis and 2) individual patient responsiveness, the fifth dimension in diagnosis.

Objectives: To show that functional jaw orthopedics for the treatment of Class II malocclusion is effective in altering short-and long-term mandibular growth and mandibular sagittal position if active treatment includes the pubertal growth spurt. To predict individual patient responsiveness, mandibular morphology should be evaluated at puberty. Ideal candidates to functional jaw orthopedics (FJO) for the treatment of Class II malocclusion associated with mandibular retrusion are characterized by a small mandibular angle (Co-Go-Me). These patients present with a favorable mandibular growth potential.

Learning objectives

understand the role of those factors that can help the clinician to improve the efficacy and efficiency of Class II treatment in the growing patient, evaluate the role of treatment timing on the short- and long-term outcomes of Class II treatment, recognize the pre-treatment craniofacial features for the prediction of successful outcomes of Class II treatment.
