1

pertains to ‘straight teeth’

orthodontia

2

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

Malocclusion

3

more than the normal amount of teeth in the mouth

hyperodontia

4

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

Class I: Neutroclusion or neutral occlusion

5

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

Class II: Distoclusion

6

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

Class III: Mesioclusion

7

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

Open bite

8

upper dentition projects further forward than the mandibular dentition.

Horizontal overlap Commonly called ‘overjet’

9

lower dentition projects further forward than the maxillary dentition

Underjet

10

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

Crossbite Also called reverse articulation

11

edges of maxillary and mandidular incisors meet each other

End to End

12

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

Preventative orthodontics

13

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

myotherapeutic (myo-therapeut-ic) exercises

14

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

Interceptive orthodontics

15

removable appliances that are designed to ensure aligned occlusion

biteplate or a bite guard

16

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

Corrective orthodontics

17

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

Accelerated osteogenic orthodontics

18

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

Adjunctive orthodontics

19

. Another term for hyperodontia could be ____
a) macrodontia
b) polydontia
c) superodontitis
d) hemiodontic

B

20

With an open bite ____
a) posterior teeth do not occlude
b) molars do not occlude
c) incisors do not occlude
d) anterior teeth are absent

C

21

Accelerated osteogenic orthodontics ____
a) requires surgery
b) is used to correct the periosteum
c) increases the amount of supernumerary teeth
d) causes reverse articulation

A

22

Maxillary teeth protruding more forward than mandibular teeth is called ____
a) openjet
b) hyperjet
c) underjet
d) overjet

D

23

Which appliances are the most common example of corrective orthodontics? ____________________________

braces

24

By its prefix, we know that myotherapeutic exercises train the ____________________________ (plural form)

muscles

25

Several specialists and/or treatments incorporated into orthodontic care is called _______________________ orthodontics

adjunctive

26

What type of malocclusion occurs when the mandibular teeth protrude more forward than the upper teeth? ________________________________________

mesioclusion

27

What is another term for reverse articulation? _________________________

crossbite
