GROWTH SPURT
Growth does not take place uniformly at all times. This period when a sudden acceleration of growth occurs and this sudden increase in growth is termed ‘Growth Spurts’.
Timings of growth spurts differs in boys and girls
The following are the timings of growth spurts:
Just Before Birth
One Year After Birth
Mixed Dentition Growth Spurt
Boys 8 – 11 years
Girls 7 – 9 years
4. Pre – Pubertal Growth Spurt
Boys 14 – 16 years
Girls 11 – 13 years
Growth modification by means of functional and orthodontic appliances elicit better response during growth spurts
Orthodontic treatment must be done earlier in girls as their growth spurt is early
The earlier the onset of puberty, the smaller is adult
Girls mature earlier but also finish their growth sooner and that leads to the difference in adult size of men and women
Arch expansion can be done during growth spurts
Class III tendency with mandibular prognathism should be treated before pre-pubertal
Class II, III malocclusion should be treated during growth spurt
If jaw growth has to be accelerated it has to be done before adolescent growth spurt in girls
Surgical correction involving maxilla and mandible should be carried out only after cessation of growth spurts
