3. Limiting Structures.A
1.Labial Frenum
2.Labial vestibule
3. buccal Frenum
4. Buccal Vestibule
5. Hamular Notch
6. Posterior Palatal Seal Area.
Extensions of posterior palatal seal:
1. Anteriorly – Anterior Vibrating Line.
2. Posteriorly – Posterior Vibrating Line
3.Lateral – Anteriolateral to Hamular Notch( 3-4 mm
distance from hamular notch)
2. Supporting structures of the maxilla:
A- Primary Stress Bearing area (Hard Palate And
Maxillary Tuberosity)
B- Secondary Stress Bearing Area ( Residual Alveolar
Ridge , Rugae Area)
Relief Areas:
Incisive Papilla , Median Palatine Raphe, Fovea
Palatine

4. Mandibular Landmarks Of denture bearing area has:
1.Limiting Structures.
2.Supporting Structures.

Mandibular Landmarks

5. 1.Limiting Structures
Labial Frenum,
Labial vestibule,
buccal Frenum,
Buccal Vestibule,
Lingual frenum,
Alveolingual Sulcus – is the space between
residual ridge and tongue
Retromolarpad,
Pterygomandibular Raphe.
2-Supporting Structures Of Mandible is (Buccal
Shelf Area, and the Residual Alveolar Ridge)
3- Relief areas of mandible is Mental Foramen,
Genial Tubercle, Mylohyoid Ridge, Mandibular
Tori.

bearing area.
Key Concepts in R.Prosthodontics:
** retention is the resistance to vertical forces or
displacement.
** stability is the resistance to lateral forces or
displacement.
**support is the factors of the bearing area that
absorb the forces of occlusion.
** palatine vault is consist of hart and soft palate it
may be U or V shape, U shape give more retention
than V shape.

6. ** The torus mandibularis is a bony prominence
usually found bilaterally and lingually near the first
and second premolars.
** retomolar pad is one of the primary supporting
areas.
