Orthodontists have made remarkable progress in their understanding of physiology, growth, tissue response, increasingly sophisticated diagnostic techniques, available materials, and information; nevertheless, with of these advances, many practitioners still find themselves at a complete loss when confronted thereupon eternal dilemma: to intervene or to not intervene before the eruption of the entire permanent dentition.
