A pmma bridge with custom abutment

A pmma bridge is a type of dental restoration made from polymethyl methacrylate (pmma), a durable and aesthetic plastic. It's commonly used for temporary or long-term provisional restorations, especially in full-arch implant cases, and is known for its strength, flexibility, and ability to be screw-retained for easy removal and adjustment. 

Key characteristics of pmma bridges:

• Material:

        PMMA is a type of acrylic plastic that is biocompatible and relatively strong. 

• Purpose:

  Temporary restorations: Often used during the healing phase after dental implant placement, or while permanent restorations are being fabricated. 

  Long-term provisional restorations: Can be used for extended periods, particularly in cases like full-arch implant restorations where a permanent solution may take time. 

  Trial bridges: Allow patients to "try out" a new smile before committing to a permanent restoration. 

• Screw-retained:

        PMMA bridges can be designed to be screw-retained, allowing for easy removal and adjustment by the dentist. 

• CAD/CAM Technology:

        PMMA bridges can be fabricated using CAD/CAM technology, ensuring a precise fit and good aesthetics. 

• Aesthetics:

        PMMA can be made in various shades to match a patient's natural teeth. 

• Durability:

        While durable, PMMA is not as wear-resistant as some other materials like zirconia and may be more prone to breakage or staining over time. 

PMMA bridges are a versatile and effective solution for various dental needs, offering a combination of strength, aesthetics, and ease of use, particularly in implant dentistry.
