Mandibular growth

Question 1

Mandibular processes from the — branchial arch

Answer 1

first

Question 2

Meckel’s cartilage

Answer 2

Meckel’s cartilage, discovered by
German anatomist J. F. Meckel (1781–
1833), is hyaline cartilage formed in the
mandibular process of the first branchial
arch of vertebrate embryos.

Question 3

Mandibular Alveolar process

Answer 3

• Tied to dental eruption
• Significant vertical
development.
• Takes place above the
mandibular canal

Question 4

Mandibular growth (3)

Answer 4

• Cartilage growth (Condyles)
• Alveolar growth (dental eruption)
• Remodeling by bone apposition and resorption

Question 5

Mandibular growth pattern:

Answer 5

It has been confirmed by the implant technique

that growth in length of the mandible in man occurs essentially at the Condyles

Question 6

Weak correlation form the size of mandible at — and the final size ( too much variation) . Same for the
shape of the face.

Answer 6

12

Question 7

Elongation of the
mandible ( 2D= AP)
(3)

Answer 7

• Apposition
• Displacement
• The mandible “catches up as it starts as
retrognathic at birth

Question 8

Vertical and transverse
growth of the ramus
(3)

Answer 8

• V of Enlow
• The vertical growth is the “result” of the
vertical displacement of the maxilla.
• Occurs at the same time and must be timed
with tooth eruption.

Question 9

Condylar growth per se.

•

Answer 9

Endochondral
growth is present
but only at the
articular surface of
the condyle because
of compressive load.
