Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) technology has become the backbone of modern dental laboratories. Understanding how it works helps clinicians communicate more effectively with their lab and achieve better clinical outcomes.
From Scan to Restoration: The Digital Workflow
The process begins with a digital scan — either an intraoral scan taken chairside with systems like 3Shape TRIOS or iTero, or a desktop scan of a physical impression. This scan is processed into a 3D model that our technicians use to design the restoration in specialized dental CAD software.
Design Phase: Where Artistry Meets Engineering
In the design phase, our technicians work with the 3D model to create a virtual restoration. They consider occlusion, emergence profile, proximal contacts, and aesthetics. The software analyzes the design in relation to opposing dentition — ensuring the final piece will function naturally in the patient's mouth.
Milling vs. 3D Printing: Which Is Better?
Both subtractive (milling) and additive (3D printing) methods have their place. Milling from pre-sintered zirconia, lithium disilicate, or PMMA blocks provides superior material density for permanent restorations. 3D printing excels for temporaries, surgical guides, and models — offering speed and cost efficiency for these applications.
Benefits for Your Practice
Working with a CAD/CAM-equipped lab means faster turnaround times, highly predictable outcomes, and fewer remakes. It also means you can send digital scans directly from your office, eliminating physical impressions and reducing the risk of distortion during shipping.
CAD/CAM technology is not just a lab tool — it is a communication platform that connects you with our team. The better we understand each other's workflows and expectations, the better the results for your patients. We welcome any questions about optimizing your digital submission process.
