    • Hand Wrist Radiographs & Maturity Indicators www.indiandentalacademy.com
    • INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
    •    Understanding of growth events is of primary importance in orthodontics. Individual variations regarding timing, velocity of growth. To assess growth, prediction of amount of growth left SKELETAL MATURITY INDICATORS are used. www.indiandentalacademy.com
    • Skeletal Maturity “a measure of how far the bones of an area have progressed towards maturity, not in size, but in shape and in their relative positions one to another, as visualized in a radiograph”. Hand Wrist Radiograph Cervical Vertebrae www.indiandentalacademy.com
    • Why study maturity indicators ? Exact status of growth ( magnitude & direction ) For treatment planning. …potential vector of facial development… …growth potential left.. ….onset of treatment timing… …type of effective treatment… Functional appliance, orthodontic fixed treatment, Orthognathic surgery. ....treatment prognosis. www.indiandentalacademy.com
    • “Chronologic age is not a reliable developmental yardstick , as it is not necessarily correlated with the maturational age of the patient” www.indiandentalacademy.com
    •  Key to successful treatment of growth .  To take advantage of growth we must have an idea of its magnitude, direction & timing.  Timing Knowledge of skeletal maturity indicators is important. www.indiandentalacademy.com Utilization
    • Handwrist radiograph Numerous small bones which show a predictable sequence of ossification from birth to maturity Ossification of the bones of hand and wrist is standard for skeletal development. Calculation of skeletal age Ossification and development of bones form a chronology of skeletal development www.indiandentalacademy.com
    • Components of hand and wrist Phalanges Metacarpals Carpals www.indiandentalacademy.com
    •  Adductor sesamoid – Small nodular bone present in region of thumb.  To obtain an estimate of timing of adolescent growth spurt www.indiandentalacademy.com

    • Stages of ossification of phalanges capping www.indiandentalacademy.com fusion
