What is Growth?
&
Why to assess it?
“biologically and histologically is a
composite of morphogenetic and
histogenetic change occurring continuously
over a period of time in response to genetic
coding and environmental influences”.
Growth
Phulari BS, Orthodontics Principles and Practice, Edition 1;205-15
“To take advantage of the growth, we must have
some idea, first, of its amount, second of its
direction and third the element of timing”
Ricketts:
Along with this we need to know when the major growth
increments are likely to occur

Phulari BS, Orthodontics Principles and Practice, Edition 1;205-15
Hand wrist radiographs
• Hand wrist region:
- Made up of numerous small bones
• These bones show:
-Predictable & scheduled pattern of
appearance
-Ossification
-& union from birth to maturity.
Phulari BS, Orthodontics Principles and Practice, Edition 1;205-15
• Thus by merely comparing a patient’s hand wrist
radiograph with standard radiographs that represent
different skeletal ages, we will be able to determine the
skeletal maturation status of that individual.

Method by Greulich
and Pyle
• In 1937, an atlas, “Atlas of Skeletal Maturation of the Hand”
published byTodd.
• Greulich and Pyle based their atlas partly on the atlas by
Todd.
• Since their atlas was first published in 1950 they were able
to use all the radiographs obtained in the original study.

• In order to determine the skeletal age using the modified Greulich
and Pyle method one uses the atlas that they have developed.
• The sex of the patient is one of the most important pieces of
information, because females develop quicker than males.
• The atlas is divided into two parts, one for the male patients and
one for the female patients.
• Each part contains standard radiographic images of the left hand
of children ordered by chronological age.

• The first step in an analysis is to compare the given
radiograph with the image in the atlas that corresponds
closest with the chronological age of the patient.
• Next one should compare it with adjacent images
representing both younger and older children.
• When comparing the radiograph against an image in the
atlas there are certain features a physician should use as
maturity indicators.

Cervical vertebrae maturation as an
indicator of skeletal maturity
In a study done by Paola it was seen thatVertebral analysis on a lateral
cephalogram is as valid as the hand-wrist bone analysis with the
advantage of reducing the radiation exposure of growing subjects.
Angle Orthodontist 2006;76 (6)
CVMI 1- Initiation:
•Inferior borders of 2nd 3rd and 4th
cervical vertebrae are flat at this stage.
•The third and fourth vertebrae are
wedge shaped and the superior vertebral
borders are tapered from posterior to
anterior.
•100% of pubertal growth remains.
•Very significant amount of adolescent
growth expected. CVMI STAGES by Hassel and Farman (1995)
Hassel B, Farman A G. Skeletal maturation evaluation using cervical vertebrae. Am J Orthod, 1995; 107:58-61
CVMI 2 -Acceleration:
• Concavities on the inferior borders of
second and third vertebrae begin to
develop.

fourth are almost square in shape.
• 5-10% of pubertal growth
remains. Hassel B, Farman A G. Skeletal maturation evaluation using cervical vertebrae. Am J Orthod, 1995; 107:58-61

Frontal sinus development as an
indicator for somatic maturity at
puberty
Ruf and Pancherz (1996)
Sabine Ruf and Hans Pancherz evaluated the development of
the frontal sinus to the longitudinal data of the subject’s growth
charts.
Results showed that Frontal sinus growth velocity at puberty is
closely related to body height growth velocity.
Ruf S, Pancherz H. Frontal sinus development as an indicator for somatic maturity at puberty?. Am J Orthod Dentofac Orthop 1996 1;110(5):476-82.
The peripheral border of the frontal sinus was traced, and the
highest (Sh) and lowest (Sl) points of the sinus extension
relative to the nasion sella line were marked. Perpendicular to
the interconnecting line (Sh-S1), the maximum width of the
frontal sinus was assessed
Ruf S, Pancherz H. Frontal sinus development as an indicator for somatic maturity at puberty?. Am J Orthod Dentofac Orthop 1996 1;110(5):476-82.
Frontal sinus shows a well defined pubertal peak (Sp), which on
an average, occurs 1.4 years after the pubertal body height
peak. (Bp).

Mid Palatal Suture
Revelo B,Fishman LS. Maturational evaluation of ossification of midpalatal suture. Am J Orthod, 1994;105:288-292
 The purpose of this study was to determine whether a
positive correlation exists between adolescent
maturational development and the approximation of the
mid palatal suture
 The mid palatal suture is formed by three parts.These
include :
-Interpremaxillary
-Maxillary
-Interpalatine
Revelo B,Fishman LS. Maturational evaluation of ossification of midpalatal suture. Am J Orthod, 1994;105:288-292
 The following key landmarks and planes were
identified :
 Point A – most ant. point of the premaxilla
 Point B – most post. point on the posterior wall of
incisive foramen
 Point P – point tangent to a line connecting the
posterior walls of the greater palatine foramens
Revelo B,Fishman LS. Maturational evaluation of ossification of midpalatal suture. Am J Orthod, 1994;105:288-292
Result
 Stages of ossification of the midpalatal suture were
compared with the Fishman’s standards of skeletal
maturation indicators.
 Very little mid palatal approx. existed during SMI 1 – 2.
Revelo B,Fishman LS. Maturational evaluation of ossification of midpalatal suture. Am J Orthod, 1994;105:288-292
 Very large increases in approximation from SMI 8 –
11
 Maturational development is related to mid palatal
fusion in ways that can provide information to better
time maxillary expansion
 It is best to accomplish this before SMI 9 and ideal
time to initiate it is between SMI 1 – 4

    Method by Greulich andPyle • In 1937, an atlas, “Atlas of Skeletal Maturation of the Hand” published byTodd. • Greulich and Pyle based their atlas partly on the atlas by Todd. • Since their atlas was first published in 1950 they were able to use all the radiographs obtained in the original study.

    • In orderto determine the skeletal age using the modified Greulich and Pyle method one uses the atlas that they have developed. • The sex of the patient is one of the most important pieces of information, because females develop quicker than males. • The atlas is divided into two parts, one for the male patients and one for the female patients. • Each part contains standard radiographic images of the left hand of children ordered by chronological age.

    • The firststep in an analysis is to compare the given radiograph with the image in the atlas that corresponds closest with the chronological age of the patient. • Next one should compare it with adjacent images representing both younger and older children. • When comparing the radiograph against an image in the atlas there are certain features a physician should use as maturity indicators.

    Frontal sinus developmentas an indicator for somatic maturity at puberty Ruf and Pancherz (1996) Sabine Ruf and Hans Pancherz evaluated the development of the frontal sinus to the longitudinal data of the subject’s growth charts. Results showed that Frontal sinus growth velocity at puberty is closely related to body height growth velocity. Ruf S, Pancherz H.
