17
Q

What are the 3 points we want to capture using the articulator and facebow?

A

Axis of rotation, plane of occlusion, and Frankfurt’s horizontal plane

18
Q

A hypothetical line through the two mandibular condyles around which the mandible may rotate.

A

Hinge Axis

19
Q

The hinge axis of the facebow is how far from the external auditory meatus in what direction?

A

10mm anterior

20
Q

On the facebow and articulator, the ____ axis is most important to understand and find

A

Transverse axis

21
Q

_______ can be measured and transferred to the articulator as the condylar angle

A

Protrusive movement

22
Q

An imaginary surface which is related anatomically to the cranium and which theoretically touches the incisal edges of the incisors and the tips of the occluding surfaces of the posterior teeth. It is not a plane in the true sense of the word but represents the mean of the curvature of the surface.

A

Plane of Occlusion

23
Q

a plane used in craniometry that is determined the highest point on the upper margin of the opening of each external auditory canal and the low point on the lower margin of the left orbit and that is used to orient a human skull or head usually so that the plane is horizontal.

A

Frankfort Horizontal plane:

24
Q

The protrusive inclination and lateral wings of the guide table should be set at

A

0 degrees

25
Q

The incisal pin is set at ______

A

zero (darkest line)

26
Q

What should the bennet angle be set to?

A

0 degrees

27
Q

What should the condylar guidance angle be set to?

A

30 degrees

28
Q

Where should the orbitale indicator be set on the patient?

A

Intra-orbital foramen

29
Q

Is the camper’s line the same are Frankfurt’s horizontal plane?

A

No

30
Q

Imaginary line running from the inferior border of the ala of the nose to the superior border of the tragus of the ear; establishes the posterior occlusal plane of the artificial teeth of the denture

A

Camper’s line

31
Q

The ala-tragus line is _____ with the plane of occlusion and is used in complete denture construction to help find the plane of occlusion

A

parallel

32
Q

What is the fashion of how the mandibular cast should be seated on the maxillary cast?

A

Maximum intercuspation
