A Removable Partial Denture (RPD) is a dental prosthesis used to replace one or more missing teeth in a partially edentulous (partially toothless) patient. It's designed to be removed by the patient for cleaning and maintenance.

🔍 Key Features:
Removable: Unlike fixed bridges or implants, RPDs can be taken out.
Partial: Used when some natural teeth remain.
Denture Base: Typically made of acrylic resin or a metal framework (often cobalt-chromium).
Artificial Teeth: Attached to the denture base to fill gaps left by missing teeth.
Retention Components: Clasps, rests, and connectors help stabilize and retain the denture.

🦷 Types of RPDs:
1. Acrylic Partial Denture (Flipper)
Often temporary.
Less durable, lower cost.
Bulky and may not fit as precisely.
2. Cast Metal Partial Denture
More rigid and durable.
Made of a metal framework with acrylic teeth.
Provides better fit and long-term performance.
3. Flexible Partial Denture
Made from flexible thermoplastics like Valplast.
No metal clasps; more aesthetic.
Comfortable but less adjustable over time.
