What is the hamular notch used for in a denture?
This is the ideal site of the distal border of the denture- This helps with the posterior seal.

The lingual sulcus.
Label A

The lingual frenulum.
Label A

This is the buccal shelf.
What is the relevance of the retromolar pad for complete dentures?
This is a triangular soft pad of tissue used to provide support.
What is the retromylohyoid space?
The area at the distal end of the lingual sulcus posterior to the mylohyoid space.
What is the Cawood and howell classification used for ?
This is used to classify the type of ridge.
What is the ideal ridge classification for our denture patients?
Broad alveolar process.
What is the disadvantage of a knife edge ridge classification?
This is painful for the patient because the load goes on the knife edge.
How does resorption affect the alveolar ridge.
Upper width decreases.
Lower width widens.
Anterio-posterio - upper resorbs backwards .
Anterior-posterior lower resorbs more vertically.

Compare Support, Stability and Retention.
Support- Resistance to vertical movement towards the tissue
Stability- Resistance to horizontal movement
Retention- Resistance to displacement in a vertical direction .
What areas in the maxilla provide support for complete dentures?
Hard palate and residual ridge. (the alveolar ridge after bone resorption)
