Study Notes
Prosthetic Dentistry
- Prosthetic dentistry focuses on replacing missing parts of the human body, particularly teeth and oral structures.
- A prosthesis is an artificial replacement for a missing part of the body.
- Prosthetics is the art and science of creating these artificial replacements.
Denture Types
- Complete Denture: Replaces all teeth in either the upper or lower jaw.
- Partial Denture: Replaces some, but not all, teeth.
- Removable Partial Denture: Can be removed and placed in the mouth.
- Fixed Partial Denture (Bridge): Cemented to natural teeth or implants.
- Immediate Denture: Temporary denture placed immediately after teeth are removed.
- Overdenture: Removable denture that covers and rests on remaining teeth, roots, or implants.
- Obturator: A prosthesis used to close openings in the mouth, either congenital or acquired.
- Implant Prosthesis: Utilizes dental implants for retention, support, and stability.
Key Concepts in Denture Design
- Support: Resistance to displacement towards the basal tissue or underlying structures.
- Retention: Resistance to displacement away from the tissues, typically by horizontal stresses.
- Stability: The quality of the denture resisting displacement by forces.
Natural vs. Artificial Teeth
- Natural teeth are firmly rooted in the jawbone, allowing for efficient chewing.
- Artificial teeth rest on oral mucosa, making chewing less efficient due to weaker support.
Objectives of Complete Dentures
- Restore Masticatory Function: Re-establish chewing ability.
- Restore Appearance: Improve facial aesthetics impacted by tooth loss and bone resorption.
- Correct Speech Defects: Ensure proper tooth placement for clear speech.
- Preserve Bone and Joint: Minimize bone loss and potential issues with the temporomandibular joint.
- Patient Satisfaction & Comfort: Ensure a well-fitting denture for comfort and ease of use.
Surfaces of a Complete Denture
- Polished Surface: The outer surface of the denture, including facial, lingual, and palatal surfaces, and labial, buccal, and lingual surfaces of teeth.
- Occlusal Surface: The surface that makes contact with opposing teeth.
- Fitting Surface (Basal, Tissue, Impression Surface): The surface that sits on the tissues.
Components of a Complete Denture
- Artificial Teeth: Replicate natural tooth function and appearance.
-
Denture Base: Rests on tissues and holds teeth, supporting the lips and cheeks.
- Denture Borders: The margin of the denture base.
-
Denture Flanges: Vertical extensions of the denture base that extend to the borders of the denture.
- Buccal Flange: Related to the cheeks.
- Labial Flange: Related to the lips.
- Lingual Flange: Related to the tongue, located in the lingual sulcus.
