How CAD/CAM Works
– Computer-Aided Design (CAD): This process involves using digital imaging to design a restoration based on a 3D model of the patient’s teeth, obtained through intraoral scanning or a conventional impression. Advanced software allows dental professionals to customize the restoration to the patient’s specific dental anatomy.
– Computer-Aided Manufacturing (CAM): Once the design is complete, it is sent to a milling machine or 3D printer. The machine fabricates the dental prosthetic from materials such as zirconia, ceramic, or composite resin. CAM technology ensures that the final restoration matches the digital design with remarkable precision.
First step: The use of Intra Oral Scanners, the future of impression taking.
Benefits of CAD/CAM
- Precision and Accuracy: CAD/CAM systems create highly accurate restorations that fit
Efficiency: The process is faster than traditional methods, reducing patient waiting time and allowing same-day restorations in some cases.
Customization: Each restoration is tailored to the patient’s unique dental structure, leading to improved aesthetics and functionality
Consistency: The digital workflow ensures consistent results, reducing the likelihood of human error during fabrication.
Material Options: CAD/CAM technology can work with various high-quality materials, providing durable and aesthetically pleasing restorations.
Applications of CAD/CAM
– Same day Inlay/Onlay: CAD/CAM is efficient in creating durable yet aesthetic restoration. Traditionally it would take one week to create. Now, with the use of CAD/CAM technology, it could be produced in a matter of 30 minutes.
– Crown and Bridge Fabrication: CAD/CAM is widely used to design and produce crowns, bridges, and veneers with superior fit and appearance.
– Implant Restorations: The technology aids in designing abutments and prosthetic components for dental implants such as prosthetic stents, customized measuring guides, and temporary crowns for immediate loading.
– Orthodontics: CAD/CAM is also used in creating clear aligners and other orthodontic appliances.
