Lecture 1 Introduction to dental anatomy

Question 1

Diagnostic wax up

Answer 1

A process in which wax is applied to a model of the patient’s teeth to simulate the procedure and results of planned reconstruction, repair, or enhancement

Question 2

Canine nickname

Answer 2

Cuspids

Essentially incisors now

Question 3

cervical line

Answer 3

Junction between the crown and root portion is marked by a distinct line

Question 4

Incisal function

Answer 4

To cut into

Question 5

Occlude

Answer 5

To come into contact with

Question 6

Occlusion

Answer 6

Contact of teeth in opposing dental arches when the jaws are closed during various jaw movements

Question 7

Palatal surface

Answer 7

Lingual surfaces of the maxillary teeth

Question 8

Which teeth do not have any teeth distal to them?

Answer 8

The distal surfaces of permanent 3rd molars and primary 2nd molars

Question 9

The mesial surface of a tooth is normally in contact with the distal surface of the adjacent tooth. When is this not true?

Answer 9

The mandibular and maxillary central incisors

Question 10

Height of contour

Answer 10

The maximum convexity of each surface

Question 11

Proximal contact area (contact point)

Answer 11

it is the portion of the proximal surface that touches the adjacent tooth

Question 12

Proximal height of contour

Answer 12

it is the portion of the proximal surface that touches the adjacent tooth

Also called the contact point

Question 13

Diastema

Answer 13

The space between the proximal surfaces of adjacent teeth if they don’t touch

Question 14

Embrasure

Answer 14

An embrasure is a “V” shaped space adjacent to the contact area of two adjacent teeth

Question 15

Labial/buccal embrasure

Answer 15

Embrasure space widens facially to form this

Question 16

Lingual embrasure

Answer 16

Embrasure space widens lingually to form this

Question 17

Incisal/occlusal embrasure

Answer 17

Embrasure space forms occlusally

Question 18

Gingival/cervical embrasure

Answer 18

triangular space cervical to the contact area

filled by interdental/gingival papilla also known as the interproximal surface

Question 19

Function of embrasures (1)

Answer 19

Provide a spillway for the escape of food during mastication

Question 20

Function of embrasures (2)

Answer 20

Prevent food from being forced through the contact

Question 21

Function of embrasures (3)

Answer 21

Embrasures and contact areas protect the gingiva from undue trauma

Question 22

Function of embrasures (4)

Answer 22

Make the tooth self cleansing as the rounded smooth surfaces of the crown are exposed to the cleaning action of fibrous foods and friction of cheeks and lips

Question 23

Function of embrasures (5)

Answer 23

Reduces force imparted on teeth during reduction of food during mastication

Question 24

Mesiodistal

Answer 24

Possible crown dimension

Question 25

Cervico-occlusal

Answer 25

Possible crown dimension

Question 26

buccolingual

Answer 26

Possible crown dimension

Question 27

Boley gauge use (2) (not that important)

Answer 27

Can be used in waxing to confirm that the wax-up is the same measurement as the contralateral tooth

Question 28

Division of crown for anterior teeth (3 ways)

Answer 28

1) Inciso-cervically
2) mesiodistally
3) labiolingually

Question 29

Division of crown for posterior teeth (3 ways)

Answer 29

1) Occluso-cervically
2) Mesiodistally
3) Buccolingually
