Hanau’s Quint equation

• Condylar inclination

• Incisal Guidance

• Cuspal Inclination

• Occlusal plane

• Compensating curve

T/F: Condylar inclination CANNOT change, since it is the anatomical relationship

True

T/F: Incisal Guidance CAN change, it is the slope of lingual surface of maxillary incisors to mandibular incisors

True

Incisal Guidance

the slope of lingual surface of maxillary incisors to mandibular incisors

• CAN change

T/F: Cuspal Inclination CAN change

True

Cuspal Inclination

Angle made by the slope of the cusp/degree of cusp

T/F: Occlusal plane CAN change

true

Occlusal plane

average plane of the incisal edges of the anterior teeth and occlusal posterior teeth (incisors to molars)

T/F: Compensating curve CAN change

true

Compensating curve

combination of curve of wilson —to— curve of spee

What do you have to do if you increase incisal guidance?

You need to adjust/increase other factors to compensate and achieve balanced occlusion

In lingualized balanced occlusion:

• maxillary lingual cusps role -

• buccal cusps role -

• maxillary lingual cusps - functional role

• buccal cusps - aesthetics role

do maxillary buccal cusps touch opposing teeth?

NO

what should you avoid when placing posterior teeth over the ridge?

avoid placing posterior teeth over the ridge where it inclines towards the retromolar pad

• most patients dont have space for 2 cuspids and 2 molars

What teeth should you omit/eliminate?

• Maxillary second bicuspid (not aesthetc)

• Mandibular first bicuspid (no occlusal contact)
