Denture Bearing Area Flashcards
1
Q
Hamular Notch (U)
A
- junction of tuberosity and hamular process
- periphery of denture should extend through these notches
2
Q
Fovea Palatine (U)
A
- air of mucous gland duct
- midline of hard to soft palate
- provides a guide to denture posterior boarder
3
Q
Incisive Papilla (U)
A
- mass of fibrous tissue behind upper incisors
- helps indicate position of centrals and canines
4
Q
Rugae (U)
A
- irregular muccosal transverse ridges
- anterior region of hard palate
5
Q
Vibrating Line (U)
A
- junction of moveable and immoveable part of soft palate
- denture extended to at least this line
6
Q
Post Palatal Seal (U)
A
- from hamular notch to hamular notch
- anterior to vibrating line
- aids in retention of denture
7
Q
Residual Ridge (U/L)
A
- can vary in height, width and consistency
- affecting tooth placement
8
Q
Tuberosity (U)
A
- lies anterior to hamular notch
- denotes limit of saddle extension
- can vary in size
9
Q
Hard Palate Mucosa (U)
A
- area of palate that denture should cover for retention
10
Q
Labial/Buccal Mucosa (U/L)
A
- space extending from frenums bounded by upper lip and residual ridge
11
Q
Suculus (U/L)
A
- deepest part of labial/buccal mucosa
- determines denture flange depth
12
Q
Frenum (U/L)
A
- muscle attachments
- could displace denture
- must be relieved
13
Q
Tori/Torus Palatinus (U/L)
A
- a bony enlargement occurring in the mid of the hard palate
- dentures can be designed around this e.g chrome skeletons or dentures with horseshoe design/hole
14
Q
Buccal Shelf (L)
A
- lies between alveolar ridge bone and oblique ridge of mandible
- extends from buccal frenum to retromolar pad
- is a flat bone covered in mucosa supporting denture
15
Q
Retromolar Pad (L)
A
- posterior portion of lower residual ridge
- contains glandular tissue and loose areolar connective tissue
- helps to indicate denture finishing line
- cover 2/3 with denture
