![]() ossification centers for the epiphyses of all phalanges and metacarpals become recognizableusually in the middle finger first, and the fifth finger last.The ossification centers of the capitate and hamate become apparent at about 3 months of age and remain the only useful observable features for the next six months.In different categories of human development, the specific ossification centers can be considered as a best predictors of skeletal maturity.In the majority of healthy children, there is an established sequence of ossification for the carpal, metacarpal and phalangeal bones, which is constant and the same for both sexes.First ossification center to appear in hand and wrist radiographs is the capitate, and the last is, most often, the sesamoid of the adductor pollicis of the thumb.Skeletal age- Most reliable age for assessment of growth for orthodontic purposesMost commonly used skeleton- Hand-wrist and cervical vertebra.GP is ofen required in O becauzeRate of facial growth n % of facial growth remaining plays imp role in making decisions regarding growth modification or orthognathic surgery.European Journal of Orthodontics 23 (2001) 105.
