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
Learn about the objectives of complete denture, including restoration of masticatory efficiency, correction of speech defects, and restoration of facial aesthetics. Understand the importance of teeth for digestion and speech, and how artificial teeth play a crucial role in restoring these functions.
