Flashcards in Lecture 1 Deck (20):
1

What three types of problems occur with maloccluded teeth?

-Psychosocial
-Oral function
-Greater susceptibility to trauma, periodontal disease and tooth decay

2

T/F Sever malocclusion is typically viewed as a social handicap

True

3

What do you see with children with articulation disorders?

-Delete sounds
-Substitute sounds
-Add sounds
-Distort sounds

4

What is the major reason people seek orthodontic treatment?

-Minimize psychosocial problems

5

What is a physiologic occlusion?

-When a patient does not necessarily have an ideal class I occlusion
-It adapts to the stress of function and can be maintained indefinitely

6

What is pathologic occlusion?

-When a patient cannot function without contributing to the dentitions and the oral facial complexes destruction

7

How does pathologic occlusion manifest itself?

-Excessive wear
-TMJ problems
-Pulpal changes ranging from pulpitis to necrosis
-Periodontal problems

8

T/F In pathologic occlusion abnormal forces are placed upon the dentition which causes the teeth to respond orthodontically to these abnormal forces

True (Termed pathologic tooth movement)

9

How is TMD manifested?

-Pain in and around the TMJ

10

In a patient with a class II malocclusion the deep anterior bite places a distalizing effect on what?

-The mandible

11

What are the four large groups for TMD?

-Masticatory muscle disorders
-TMJ disorders
-Chronic mandibular hypomobility
-Growth disorders

12

What one TMD group can be treated with orthodontics?

-Masticatory muscle disorders

13

What is myofascial pain?

-develops when muscles are overly fatigued and tend to go into spasm

14

What is splint therapy used to help identify?

-If the malocclusion is a possible cause of the patients TMD

15

What teeth should the splint cover?

-All of the teeth

16

What is the goal of splint therapy?

-Create a bite plane where the patient can function by removing any abnormal occlusal interferences

17

T?F Malocclusion, particularly protruding maxillary incisors can increase the likelihood of an injury to the teeth

True

18

What are the odds that a child with untreated class II malocclusion will experience trauma to the upper incisors?

1 in 3

19

What can cross bites and traumatic occlusions cause?

-Extreme wear
-Gingival recession
-Bone loss on the misaligned teeth

20

T/F Cross bites don't influence growth and stress on the TMJ

False
-They can also influence growth as well as cause stress on the TMJ
