Complete denture: A dental prosthesis that replaces the entire natural dentition (complete loss of natural teeth)and its associated structures of the mandible and / or the maxilla. Partial denture: A dental prosthesis that replaces one or more but less than all the natural teeth and its associates structures and that is supported by teeth and or the mucosa. It may be fixed or removable. Definitions  Fixed partial denture: A partial denture that is cemented to natural teeth or tooth roots and or fixed to dental implant.  Removable partial denture: A partial denture that can be removed from the mouth and replaced. Retention Support Stability  Functions of complete dentures 1. Mastication: 2. Speech (Phonetics) 3. Appearance (Esthetics) 4. Health of the alveolar hone and temporomandibular joints  improve masticatory function Before treatment After treatment Restoration of speech  Improve aesthetics Before After Health of the alveolar bone and temporomandibular joints Morphology of complete denture  Denture base: The part of the denture that rets on the foundation tissues and to which teeth are attached. Denture surfaces (3 surfaces) A- Basal (impression surface) the denture that has its contour determined by the impression. B- Denture polished surface the denture surface that extends from the borders of the denture and includes the facial, lingual and palatal surfaces facing lips, checks and tongue. C- Denture occlusal surface the denture surface that makes contact or near contact with its antagonist. Denture borders: the margin of the denture base at the junction of the polished surface and the impression surface.  Denture flanges: the vertical extensions of the denture base that extend from the cervical ends of the teeth to the borders of the denture are called denture flanges.  A- buccal flange: the portion of the flange of a denture that occupies the buccal vestibule.  B- Labial flange: the portion of the flange of a denture that occupies the labial vestibule.  C- Lingual flange: the portion of the flange of a denture that occupies the lingual vestibule.  Denture surfaces  Fittingsurface  Polished surface  Occlusal surface Complete denture surfaces and flanges  STEPS OF COMPLETE DENTURE CONSTRUCTION CLINICAL LABORATORY 1-History taking and mouth examination. 1 2-Preliminary impression. 3-Casting of the preliminary impression. 1 4-Construction of special trays 2 5-Final impression. 6-Boxing-in and casting of the final impression 2 7-Construction of record blocks. 8-Recording of jaws relationships and selection of 3 artificial teeth. 9-Mounting of the models on an articulator. 3 10-Setting -up of teeth and waxing up. 4 11-Tryin-in of the waxed-up dentures 12-Flasking Wax elimination Packing Curing 4 Deflasking.
