After parturition, how does the skull grow? Is the growth less when compared to pre-natal or body growth? The transformation, translation and remodelling that takes place ensures that facial skeleton assumes the shape and form that it is destined to (genetics) and according to presenting variables like hormones, diet and local factors (epigenetics). The growth of the facial skeleton is proportionate, dynamic and differential. As explained in this chapter, bone ossifies at different times and this accounts for plasticity and late expression of growth. Growth of the dentition at this juncture does influence the growth of maxilla and mandible and vice-versa. How the balance is achieved forms the “nerve” of servo system concept. Does growth centre/site really exist? From an orthodontist point of view, timing such growth is absolutely imperative for growth modification procedures.
