There has been a controversy regarding the timing of orthodontic treatment for correction of class II malocclusion. This article reviews the various aspects of orthodontic treatment timings in the light of current literature. Early orthodontic treatment is effective and desirable in specific situations and has been shown successful by many studies. However, the recent evidences indicated that that such an approach might not be more effective than a single-phase treatment. Therefore, clinicians must review various parameters and decide on a case to case basis, the ideal timing of orthodontic treatment considering the effectiveness, cost benefit ratio, long-term stability, patient compliance and duration of treatment. For some patients early treatment may be advisable but for many it may be better delaying treatment until later in their dental and skeletal development.
