The mid-to-late childhood and adolescent periods of development
are associated with widely varying rates of skeletal development.
The relative amounts of growth velocity that a developing individual
demonstrates is directly related to the amounts of downward and
forward maxillary and mandibular growth that is exhibited. This is
of particular significance to the clinician since growth related
mechanics depends on good to excellent correlation with growth timing
and growth amounts. Growth rate (velocity) by definition is a factor
of the incremental amount of growth per unit of time.
The following chart depicts the general growth curve that individuals
express. The shape of the curve varies relative to the maturational
level (advanced vs. average vs. delayed) of the patient.
The following general characteristics are associated with the
Late childhood ( SMI F to K ) - low growth velocity
Early adolescence ( SMI 1 to 4 ) - accelerating growth velocity
Mid-adolescence ( SMI 4 to 8 ) - high growth velocity
Late adolescence ( SMI 8 -11 ) - decelerating growth velocity
All of the above factors vary
relative to the 23 stages and
14 levels of maturation. The GrowthTek Patient Report
evaluates the specific developmental factors regarding your
patient's unique maturational profile.
refer to the 'Clinical Applications' section of this web site
for pertinent information regarding rational timing of treatment
relative to growth velocity.
