According to Dr. Hang, there is only one measurement that any orthodontist (or parent for that matter) needs to predict how a child's face will develop. Dr. Hang spent years trying to disprove that facial growth diagnostics could be so simple. But, the evidence piled up and he finally agreed that this one measurement is all you need to determine the direction of your childs growth.
