Occlusion for dentures Flashcards
What is the intercuspal position?
the complete intercuspation of the opposing teeth independent of condylar position
what is the retruded contact position?
guided occlusal relationship occurring at the most retruded position of the condyles in the joint cavities
what are index teeth?
contacting facets of teeth in the intercuspal position
ICP key features
need sufficient index teeth
stable occlusion
may vary through life
depends on tooth relationships
sometimes more anterior than RCP
RCP key features
insufficient index teeth
unstable occlusion
most reproducible position
is a condylar position
sometimes more posterior than ICP
when to conform to existing occlusion
stable occlusion
sufficient index teeth
usually use ICP
when to change existing occlusion
lack of sufficient index teeth
often use RCP
usually more challenging to record occlusion
what materials can be used to take an interocclusal record?
bite registration paste
wax wafer
modified wax wafer
- e.g. alminax
