CAD CAM DENTAL RESTORATIONS….

1. What Are CAD/CAM Dental Restorations?

CAD/CAM stands for Computer-Aided Design / Computer-Aided Manufacturing. In dentistry, it’s used to digitally design and fabricate restorations like:

• Crowns
• Bridges
• Veneers
• Inlays and Onlays
• Implant abutments

Instead of traditional impressions and lab work, the restoration is designed on a computer and milled from a block of ceramic, metal or zirconia.

2. The Process

1. Tooth Preparation:
   1. Decay or old restorations are removed, and the tooth is shaped.
2. Digital Impression:
   1. A 3D scanner captures the exact shape of the prepared tooth surface.
3. Finishing & Placement:
   1. Polishing, staining, and glazing may be done, and then the restoration is bonded or cemented in place.

3. Advantages

• Precision Fit: Very accurate margins and contacts.
• Strength & Durability: Materials like zirconia are highly resistant.
• Aesthetic: Natural tooth-like appearance.
• Time-Efficient: Many restorations can be completed in a single visit.
• Digital Workflow: Easy to store designs and replicate restorations if needed.

4. Materials Used

• Ceramic (Porcelain): Highly aesthetic, tooth-colored.
• Metal: Less expensive, easier to adjust.
• Zirconia: Extremely strong, ideal for posterior teeth and bridges.

In short, CAD/CAM restorations are precise, strong, and highly aesthetic  and more convenient .
