1. COMPONENTS OF A COMPLETE DENTURE Surfaces of a denture Parts of a denture Dr Aaryas Vlogs

2. Surfaces of a complete denture Impression/intaglio surface Polished /external/cameo surface Occlusal surface

3. Impression surface : The portion of the denture surface that has its contour determined by the impression , syn , IMPRESSION AREA , INTAGLIO SURFACE

4. Cameo surface : The viewable portion of a removable denture prosthesis ; the portion of the surface of a denture that extents in an occlusal direction from the border of the denture and includes the facial, lingual and palatal surface ; it is the part of the denture base that is usually polished , and includes the buccal and lingual surfaces of the teeth.

5. Occlusal surface : A surface of a posterior tooth or occlusion rim that is intended to make contact with an opposing occlusal surface.

7. Denture base The part of a denture that rests on the foundation tissues and to which teeth are attached. Forms the foundation of the denture. Helps to distribute and transmit the forces acting on the denture teeth to the basal tissues. Adequate extension of the denture base helps in providing retention and support. Denture bases made of acrylic resin or metal.

8. Acrylic resin denture base Most commonly used material Easy to fabricate. Economical Supplied as powder (polymer) and liquid (monomer).

9. Metal denture base Fabricated using Gold, Gold alloys, Chromium-Cobalt or Nickel-Chromium alloys. Difficult to fabricate Easier to maintain

10. Denture flange The part of the denture base that extends from the cervical ends of the teeth to the denture border. Provides peripheral seal and horizontal stability. Classified according to the vestibule where it extends as— labial, buccal and lingual.

11. Labial flange The portion of the flange of a denture that occupies the labial vestibule of the mouth. Provides lip support. V-shaped notch is provided in the labial flange to accommodate the labial frenum .

12. Buccal flange The portion of the flange of a denture that occupies the buccal vestibule of the mouth. • Provides the cheek support. • Relief is provided to accommodate the buccal frenum .

13. Lingual flange The portion of the flange of a mandibular denture that occupies the alveololingual sulcus Should maintain contact with the tissues of the floor of the mouth.

14. Denture border 1. The margin of the denture base at the junction of the cameo surface and the intaglio surface. 2 . The peripheral border of a denture base at the facial, lingual, and posterior limits.

15. Responsible for maintaining the peripheral seal. Should be smooth and polished. Overextended denture borders may cause ulcers and hyperplasia. Underextended borders result in loss of peripheral seal and compromise retention.

16. Denture Teeth A term commonly referring to an artificial tooth used in the fabrication of a resin base prosthesis.
