Question 2

term used to describe a “state of not closing well”

Answer 2

Malocclusion

Question 3

more than the normal amount of teeth in the mouth

Answer 3

hyperodontia

Question 4

anterior and posterior dental occlusion is normal, or mesial and distal occlusion is normal, but individual teeth are not aligned

Answer 4

Class I: Neutroclusion or neutral occlusion

Question 5

anterior and posterior teeth alignment is abnormal, causing the maxilla (upper jaw) to protrude more forward than the mandible (lower jaw)

Answer 5

Class II: Distoclusion

Question 6

anterior and posterior teeth are aligned abnormally, causing the lower jaw (mandible) to protrude further forward than the maxilla

Answer 6

Class III: Mesioclusion

Question 7

posterior (back) teeth occlude, but the anterior (front) teeth do not

Answer 7

Open bite

Question 8

upper dentition projects further forward than the mandibular dentition.

Answer 8

Horizontal overlap Commonly called ‘overjet’

Question 9

lower dentition projects further forward than the maxillary dentition

Answer 9

Underjet

Question 10

abnormal superior-inferior alignment and occlusion of a tooth with its opposing tooth. May involve one or more teeth.

Answer 10

Crossbite Also called reverse articulation

Question 11

edges of maxillary and mandidular incisors meet each other

Answer 11

End to End

Question 12

the goal is to maintain current dental and occlusion integrity and preventing the development of abnormalities.

Answer 12

Preventative orthodontics

Question 13

exercises are individualized to each patient, to ensure that the muscles are ‘trained’ to perform at their optimum

Answer 13

myotherapeutic (myo-therapeut-ic) exercises

Question 14

this method is aimed at limiting the extent of an existing concern related to abnormal growth patterns, to prevent further problems.

Answer 14

Interceptive orthodontics

Question 15

removable appliances that are designed to ensure aligned occlusion

Answer 15

biteplate or a bite guard

Question 16

intervening with the application of appliances that alter the positioning and movement of teeth. The most common example would be ‘braces’.

Answer 16

Corrective orthodontics

Question 17

braces and retainers align dentition after bones have been weakened through a surgical procedure. As bones heal, teeth retain their new alignment

Answer 17

Accelerated osteogenic orthodontics

Question 18

collaboration with other specialists to correct underlying conditions that are responsible for the malocclusion

Answer 18

Adjunctive orthodontics
