PMMA Bridge With Ti-Base Screw Retained Trying For Full Arch Restoration

An pmma bridge

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.
