Q

Hanau Quint: 5 Factors Affecting Articulation of denture teeth, which are…

(5 factors affecting occlusal balance)

A

Condylar inclination/guidance

Incisal guidance

Compensating curve (Spee/Wilson)

Cusp angle/height

Plane of occlusion and its orientation

148
Q

In the Hanau Quint, what is the only factor that can’t be controlled? `

A

Condylar Inclination

149
Q

How can you get an Accurate Condylar Inclination?

What is the Avg inclination we use in dentures?

A

Protrusive check bite-record

30 degrees

150
Q

Angle formed by drawing a line in the Sagittal Plane between the Incisal Edge of the Mx/Mn teeth when teeth are in CO and the Horizontal Plane

A

Incisal Guide Angle

151
Q

Condylar Inclination x Incisal Guidance / Occlusal Plane x Cuspal Inclination x CompCurve

A

Theilman’s Formula

= C (balance occlusion)

152
Q

Theilman’s Formula

= C (balanced Occlusion)

A

Condylar Inclination x Incisal Guidance /

Occlusal Plane x Cuspal Inclination x CompCurve

153
Q

An increased incisal guidance can be compensated by increasing one of what 3 things?

***or??

A

OccPlane

Cuspal Inclination

Comp Curve

***or a Balancing Ramp

154
Q

In Theilman’s Formula, the Occlusal Plane can be altered

A

False

  • *not substantially
  • **functional requirements dictate position
155
Q

Theilman’s Formula (Hanau Quint), what is very helpful in obtaining balanced occlusion (depending on the posterior tooth forms it can easily be corrected to facilitate posterior tooth contacts in eccentric positions)

A

Compensating Curve

CompCurve

156

** 33 degree

A

DB cusp Mx 1M - 1/2 mm

DL cusp 1/2 to 3/4 mm
