The anterior replacement tooth in an RPD is most commonly made from which material?

• A. Acrylic resin
• B. Ceramic
• C. Glass-filled resin
• D. Gold alloy

Answer: (A)

In removable partial dentures, the replacement teeth for the anterior region are most commonly acrylic resin. This material matches well with the common acrylic denture base, allowing a strong bond between tooth and base and enabling a single, cohesive pink-and-white appliance. Acrylic resin teeth are easy to adjust, repair, and polish chairside, which is crucial for a removable appliance that may need refinements over time. They’re also lighter, more forgiving if the denture is worn by first-time patients, and cost-effective. Ceramic or porcelain teeth, while very wear-resistant and esthetically distinct, are more brittle and harder to adjust in a removable appliance; they can cause wear on opposing teeth and require more precise occlusion, making them less practical for routine RPD use. Glass-filled resin is not the standard choice for anterior replacement teeth in RPDs, and gold alloy would not provide the natural tooth appearance and bonding compatibility typical of denture teeth.
