Dentures lecture 4
3 features of complete denture occlusion
Bilateral posterior centric contact
Balanced occlusion to minimize tipping
Define bilateral balanced denture occlusion
Stable, simultaneous contact of upper and lower teeth in
bilateral gliding contact
within the normal range
Developed to lessen/limit tipping or rotation of the denture bases
what is required to establish balanced occlusion?
Representation of patient's jaw relationship
Analogue of patient's mandibular movements
**This means mounting on an articulator**
How do we establish maxillo-mandibular relation records?
1)adjust occlusion rims to reflect tooth position
2)Relate maxilla to hinge axis- simulate condyle
3) Establish vertical separation (VDO)
4)Relating mandible to the maxilla (centric relation)
5)Set the condylar inclination (protrusive record)
What is Vertical Dimension of Occlusion?
The length of the face when teeth are contacting and the teeth are in
What is the freeway space?
- distance between occluding surfaces of maxillary and mandibular teeth when the mandible is in its physiologic rest position
What is Centric Jaw Relation?
mandible to the maxilla
when the condyles are in their
most superior/anterior position
in the glenoid fossa
From here unstrained lateral movements can be made at the normal occluding vertical dimension
This is not maximum intercuspation
What are the five factors of
3)Occlusal Plane inclination
4) Compensating curve
5) Cuspal inclination
How are the 5 factors of hanau's quint related?
Condylar inclination X Incisal Guidance
OccPlane X Cuspal Inclination X CompCurve
Why do monoplane teeth need balancing ramps?
This stabilizes the denture base during mandibular movements
It counters for lacking
occlusal plane inclination
Which factors in hanau's quint can we not change?
Condylar inclination and occlusal plane
