Growth modification, as the name suggests, is a process by which an Orthodontist can modify the jawbone, length, shape, position etc. Growth modification appliances used by our Orthodontists include Headgear, Rapid Patal Expanders, functional appliances like Twin blocks, and Frankel appliances. An important consideration with Growth Modification is that the patient should be in a peak growth spurt of their life, i.e. between ages 10-12 years for girls, and 11-14 years for boys.
