Mandibular Growth Genetics

Question 1

Answer 1

the first branchial arch

Question 2

what is meckels cartilage

Answer 2

hyaline cartilage formed in the mandibular process of the first branchial arch of vertebrate embryos

Question 3

describe mandibular alveolar process

Answer 3

-tied to dental eruption
-significant vertical development
- takes place above the mandibular canal

Question 4

where does cartilage growth in the mandible occur

Answer 4

in the condyles

Question 5

what is alveolar growth in the mandible based on

Answer 5

dental eruption

Question 6

what is remodeling of mandible done by

Answer 6

bone apposition and resorption

Question 7

mandibular growth has been confirmed by :

Answer 7

the implant technique that growth in length of the mandible occurs essentially at the condyles

Question 8

weak correlation from the size of the manible at 12 and the ____. same for _____

Answer 8

final size; shape of the face

Question 9

the mandible starts as ______ at birth

Answer 9

retrognathic

Question 10

how does elongation of the mandible occur

Answer 10

apposition and displacement

Question 11

describe vertical and transverse growth of the ramus

Answer 11

• 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 12

why is endochondral growth present at the articular surface of the condyle

Answer 12

because of the compressive load
