What is the primary support area of the mouth on full lower dentures ?
Buccal shelf.
What 8 parts of the mouth should be examined with denture in situ ?
Occlusal plane - anterior and posterior.
Vertical height.
Occlusion recorded correctly.
Lip support.
Overextension or under extension.
Retention.
Stability.
Adaptation.
How is vertical height calculated ?
RVD-OVD = freeway space.
Definition of ICP.
Complete intercuspation of opposing teeth independent of condylar position.
Definition of RCP.
Guided occlusal relationship at most retruded position of condyles in joint cavities.
What is the most reproducible occlusion position ?
RCP.
Why is ICP not used in complete cases ?
No opposing natural teeth.
Definition of retention.
Resistance to displacing forces away from ridge.
Definition of stability.
Ability of denture resistance to displacement due to functional stress.
Definition of adaptation.
Degree of fit between a prosthesis and supporting structures.
What 4 things does denture assessment form assess ?
Base extension.
Tissue adaptation.
Appearance.
Relationship of dentures.
What is a tissue conditioner ? When is it used ? And why ?
Tissue conditioner materials are the temporary soft lining materials that are used to treat the damaged mucosa, ensures even application of pressure on fitting surface of the denture and underlying mucosa.
