Occlusion Flashcards
When is occlusion important
Reduce risk of fracture /wear/failure
- tooth
- restoration
What is the risk if you get the occlusion wrong
Risk of fracture
What is a static occlusion
The occlusion the patient makes when they fit the teeth together
What is the dynamic occlusion
The occlusion a patient makes when they move the jaw sideways
How can we mark occlusal contacts
Using articulating paper
Why should we use thin articulating paper
They minimise tooth contacts artefacts and clearly indicate tooth contact details
What scan can be used to detect occlusal contacts
T scan
How must articulating paper be placed
The articulating papers must be placed simultaneously on the two sides
What can be used to hold articulating paper
Y type holder
Fix clip bite frame
What is ideal articulating paper to use
Thinnest possible
What forceps can be used with articulating paper
Use miller forceps, securely grip the entire length of the articulating paper
Describe what state the teeth should be in when using articulating paper
Teeth should be dry
What are the stages of placing a restoration
Etching, priming, bonding and filling
Describe heavy contacts and articulating paper
On heavy contacts more colour is squeezed out
What is tripodization
Each centric cusp contacting an opposing fossa has three reciprocating contact areas
