1. CERVICAL VERTEBRA MATURITY
INDICATORS

3. Skeletal
Age
Assessment
Hand wrist
radiograph
Cervical
vertebra
Frontal &
maxillary
Sinus
Midpalatal

Canine
Calcification

4.  Suggested by Lamparski in 1972.
 Possible with routinely taken lateral
cephalograms mainly taken to asses
the antero-posterior & vertical
relation of the jaws

5. o To determine whether the case can be treated by
Myofacial Appliance
Orthopaedic Appliance

6.  Variables analyzed:
1. Concavity at lower border of C2, C3 & C4
2. Shape of the body of C3 and C4
 Trapezoid : least mature
 Rectangular horizontal
 Squared
 Rectangular vertical : in adult life

7.  Hassel & Farman1 suggested 6 stages of
cervical vertebral maturation
1. Initiation
2. Acceleration
3. Transition
4. Decceleration
5. Maturation
6. Completion
