Class II Angle division 1 malocclusion is type of malocclusion with difficult complexity to handle. ICON (Index of Complexity, Outcome and Need) is an occlusal index that can be used to determine treatment needs, complexity, outcome acceptance and degree of improvement of malocclusion class II division 1. The aims of this study is to evaluate assessment standards for the treatment outcome and its relation with the treatment need, appointment frequency and duration of treatment in the case of class II division 1 malocclusion. The sample of this study are study model before and after patients class II division 1 malocclusion treated at the Orthodontic Specialist Clinic Faculty of Dentistry Airlangga University in 2005 - 2010. The study models before treatment were assessed by ICON for treatment needs and complexity of the case. Further progress model after treatment were then assessed by ICON for outcome acceptance and degree of improvements. This study calculated the duration of treatment and the frequency of appointment as well.
The results of the study showed that all of the samples, need the orthodontic treatment and 40% of them categories as difficult cases. The treatment results showed that the acceptable and degree of improvement are almost 100%. There is a relationship between the treatment needs, and frequency of appoinment compared to the outcome of treatment with significance different on both results (p<0.05).
