MAXILLARY DENTURE

PRIMARY STRESS-BEARING AREA
Posterolateral slopes of the hard palate

PRIMARY RELIEF AREAS
Mid-palatine raphae
Incisive papilla
- Why it needs relief? Contains nasopalatine nerve* & not incisive nerve OK!
- When compressed, causes paresthesia of anterior palate*
Rugae
- Secondary relief – optional answer for primary relief OK!


PRIMARY RETENTION AREA

Post Palatal Seal area
THE MOST IMPORTANT FACTOR PROVIDING RETENTION OF A CD IS THE PERIPHERAL SEAL.
PP Seal: At the soft palate

SOFT PALATE:
- Supplied by the accessory nerve of the Vagus nerve
- Thus any patient with vagus nerve damage – will not be able to record PPS – thus no retention here
