What are the 5 Factors in Hanau’s quint?
|
Condylar inclination, incisal guidance, occlusal plane, cuspal inclination, compensating curve.
|
|
|
If the vertical overlap of the anterior teeth must be decreased for phonetics, name two factors in Hanau’s quint that can be easily altered by the dentist to maintain balanced occlusion. For each of these two factors, state where they must be increased or
|
Compensating curve—decreased
Cuspal inclination—decreased |
|
|
What is cuspal centric relation?
|
Good bilateral contacts in posterior teeth of patient in centric occlusion in vertical dimension
|
|
|
What is the purpose of the posterior palatal seal?
|
• Maintenance of peripheral seal.
|
|
|
What does it compensate for?
|
• Polymerization shrinkage and minor denture base movements
|
|
|
What is the most favorable house classification?
|
• Class 1
|
|
|
Give 2 reasons why it is the most favorable classification.
|
• Less soft palate movement
• less palatal curvature. • more denture base to palatal surface area contact |
|
|
What is the definition of the vibrating line?
|
• Junction of the mobile and non-mobile portions of the soft palate.
|
|
|
• Bilateral Balanced Denture Occlusion
|
o The stable simultaneous contact of opposing upper and lower teeth in centric relation position with a smooth bilateral gliding contact to any eccentric position within the normal range of mandibular function, developed to limit tipping or rotation of the denture bases in relation to the supporting structures
|
|
|
• VDR:
|
Vertical Dimension of Rest
o Length of face(nose to chin) when mandible is in rest position |
|
|
• VDO
|
o Length of face(nose to chin) when teeth are in contact and mandible or the teeth are in centric
|
|
|
• Interocclusal Distance of Freeway space
|
o Distance b/w occluding surface of max/mand when mandible is in physiological rest position
|
|
|
• CR
|
o Condyle in most anterior/superior position in glenoid fossa
|
|
|
• Hanau’s Quint
|
o CI x IG / OccPlane x Cuspal Inclination x Comp curve
|
|
|
If the vertical overlap of the anterior teeth must be decreased for phonetics, name two
factors in Hanau’s quint that can be easily altered by the dentist to maintain balanced occlusion. For each of these two factors, state where they must be increased or decreased. |
-decrease compensating
-decerase cuspal inclination |
|
|
• Posterior disclsuion minimized by
|
o Minimizing incisal guidance
