Study Notes
Objectives of Complete Denture
- Restoration of masticatory efficiency is crucial for good digestion and optimal health
- Correction of speech defects is necessary, as teeth are required for effective speech and proper placement of artificial teeth is essential for restoring good speech
- Restoration of facial contour and appearance is vital, as loss of teeth can lead to a prematurely aged appearance
- Patient satisfaction and comfort are critical, as a dental prosthesis must be comfortable and psychologically accepted by the patient
Parts of Complete Denture
- Artificial teeth have three functions: mastication, speech, and esthetic
- Denture base has four functions: carrying teeth, esthetic, retention, support, and stability
- Denture flanges are the vertical extension of the denture base and are named according to location: labial, buccal, and lingual
- Denture borders are the margins of the denture base at the junction of the polished and fitting surface
- Denture surfaces include: fitting surface, polished surface, and occlusal surface
Steps of Complete Denture Clinical Laboratory
- Steps include: primary impression, pouring, primary cast, special tray, secondary impression, pouring, secondary cast, record block, maxillo-mandibular relationship, mounting, teeth setting, try-in, flasking, and insertion
Anatomical Landmarks
Maxillary Landmarks
- Supporting structures: alveolar ridge, maxillary tuberosity, palate, and rugae area
- Relief structures: incisive papillae, median palatine raphe, fovea palatinae, and torus palatinus
- Limiting structures: labial frenum, labial vestibule, buccal frenum, buccal vestibule, and posterior palatal seal
Mandibular Landmarks
- Supporting structures: buccal shelf of bone, retromolar pad, and well-developed alveolar ridge
- Relief structures: resorbed alveolar ridge
