When an RPD includes an anterior replacement tooth, which material is commonly used for the tooth?

• A. Acrylic resin
• B. Porcelain
• C. Glass ceramic
• D. Metal

Answer: (A)

In removable partial dentures, the tooth component for an anterior replacement is usually acrylic resin. This material integrates well with the acrylic denture base, allowing a strong bond between teeth and base, easier chairside adjustment, and straightforward repairs if needed. Acrylic resin teeth are also cost-effective and can be color-matched to look natural, which suits most esthetic needs for anterior positions. Porcelain or glass ceramic teeth are tougher and more wear-resistant, but they’re brittle and prone to chipping or fracture in the daily, sometimes uneven loads of a removable denture. They can also wear opposing natural teeth and require a more complex fabrication. Metal isn’t used for the tooth portion because it doesn’t provide natural tooth aesthetics and would not match the appearance of a typical maxillary or mandibular anterior denture. So, acrylic resin is the best choice for anterior RPD teeth because it harmonizes with the denture base, is easy to adjust and repair, and offers adequate aesthetics at a lower risk of fracture.
