Dentures are removable prosthetic devices replacing missing teeth and surrounding tissues. They restore function, support facial muscles, and improve aesthetics for patients with partial or full edentulism. Modern dentures combine advanced materials and techniques for optimal fit, comfort, and appearance.

Types of Dentures

1. Complete Dentures

• Conventional: Made after teeth removal and tissue healing (8–12 weeks post-extraction).
• Immediate: Fabricated in advance; placed on the same day as extractions to minimize edentulous period.
• Overdentures: Fit over remaining teeth or implants to enhance retention and stability.

2 . Partial Dentures

• Acrylic (Flipper) Partials: Temporary, cost-effective, easy to adjust.
• Cast Metal Framework Partials: Durable metal framework with acrylic base and clasps; removable and precise fit.
• Flexible Partials: Nylon thermoplastic base without metal clasps for improved comfort and aesthetics.

3 . Implant-Supported Dentures

• Locator Attachments: Overdentures secured by locator abutments on implants; enhanceretention.
• Fixed Hybrid Dentures (All-on-4/6): Screw-retained full-arch prosthesis fixed on 4–6 implants; removal only by a dentist.

Candidate Assessment

• Oral Examination: Evaluate ridge anatomy, soft tissue health, and tongue function.
• Bone & Tissue Assessment: CBCT for implant overdenture planning; ensure sufficient ridge height for conventional dentures.
• Functional Analysis: Assess occlusal vertical dimension (OVD), centric relation (CR), and esthetic lip support.

Advantages & Considerations

• • Cost-Effectiveness: Lower initial cost compared to implants; suitable for those unsuitable for
    surgery.

• • Versatility: Easily modified or extended if additional teeth are lost.

• • Aesthetic Support: Restores facial contours, lip support, and smile appearance.

• • Limitations:

• • Less stable than fixed options; may require adhesives.

• • Acrylic bases prone to wear; periodic relining or replacement every 5–7 years.
  • Potential for reduced taste sensation and gag reflex in some patients.
