Flashcards in Occlusion Deck (23):
1

What are some things to be taken into consideration when thinking about occlusion

Contact points
Tooth alignment
Incisal relationships
Cross bites
Intercusual position
Molar relationships

2

At the contact point of teeth what is to be cautious of

The stagnation which may occur leading to caries

3

What is the contact point critical for

Mastication
Arch alignment and stability

4

What are the arch relationships

Upper arch overlaps lower
Upper buccal cusps are buccal to lower buccal cusps

5

What does each tooth contact with

It's distal neighbour and lower antagonist

6

What is the tooth alignment determined by

Path of eruption
Forces exerted on the teeth by- teeth, soft tissues, foreign objects

7

What is the zone of equilibrium between forces exerted on the tooth called

Neutral zone

8

What is the neutral zone clinically important for

Dentures

9

What is the Curve of Wilson

laterally across mouth form ear to ear

10

What is a cross bite

When lower buccal cusps are buccal to upper buccal a cusps

11

What are the two types of cross bite and which is easier to rectify

Bilateral or unilaterl
Bilateral easier to rectify

12

What is the curve of spee

From front of mouth the back

13

What is Angels classification

Relationships between upper and lower 6's
Particularly the MB cusp and MB groove

14

What is class 1 of angles classifications

The MB cusp occluded in MB groove

15

What is class 2

The MB cusp occluded anterior to MB groove

16

What is class 3

The MB cusp occluded posterior to MB groove

17

What is an overbite

When a tooth overlaps on the vertical plane

18

What is an open bite

When the teeth have no contact

19

What is an over jet

When the teeth overlap in a horizontal plane - protrudes Anteriorly

20

What is a reverse overjey

When the upper incisors are behind the lower incisors

21

What are the incisor relationships

Relates lower incisor tip to the Cingular plateau of the upper incisor

22

What are the incisor classifications

Class 1 - normal
Class 2 - overjet
Class 3 - overbite
Class 4 - reverse overjet

23

What is occlusion

Contact relationships between teeth within and between arches
