1
Q

This school of articulator design focuses to put the teeth in the proper position; denies the existence of condylar axes and disregards condylar paths

A

The geometric (non-anatomical) school

2
Q

This school of articulator design involved adjustable condylar guides and average value instruments; uses the anatomy

A

The condylar (anatomic) school

3
Q

This person came up with the Equilateral Triangle Theory (1864)

A

William G. A. Bonwill

4
Q

What are the measurements of the equilateral triangle theory

A

the size of the mandible is equal to 10cm (4 in) from condyle to condyle and from each condyle to the incisor point (24/25)

5
Q

This person came up with this angle; formed between the occlusal plane and the Bonwill triangle

A

Francis H. Balkwill (1866)

Balkwill angle

6
Q

What is the degrees of the Balkwill angle

A

26º

7
Q

This is the relationship between the curved arrangement of the occlusal planes of teeth and the corresponding curves of the condylar paths

A

curve of Spee

Ferdinand Graf von Spee

8
Q

Where is the center of rotation/the location of the axis of the cylinders curvature of the curve of Spee

A

the mid orbital plane

9
Q

Where would the curve of Spee continue to when following the posterior continuation of the molars

A

to the anterior point of the condyle

10
Q

The steeper the path of the condyles the (more or less) pronounced the curve of Spee

A

more pronounced

11
Q

This person discovered that the mandible moves downward upon protrusion

A

Carl Christensen

12
Q

Christensen was the first to describe an intraoral method for what

A

obtaining a protrusive record to determine the condylar inclination

13
Q

Which arch is naturally convex in nature? concave?

A
convex = maxillary
concave = mandibular
14
Q

This person presented a method for setting denture teeth. using Bowills equilateral triangle conforming to the surface of a sphere (1898)

A

George S. Monson

15
Q

Where in the head region is Monson’s center of rotation located; Monson’s spherical theory

A

sella turcica

16
Q

What specific entity all touch at Monson’s center of rotation

A

the long axes of all teeth

17
Q

This theory states that occlusion should be spherical, the curvature of the cusps as projected on the frontal plane expressed in both arches

A

Curve of Wilson

18
Q

What is the shape of the curve of Wilson in the maxillary and mandibular arches

A
maxillary = convex
mandibular = concave
19
Q

What was considered the anatomic rotation center of the mandible according to Rupert Hall’s conical theory of mandibular movement

A

external occipital protuberance
