CAD/CAM Dental Technology: Fundamentals, Workflow & Benefits for Dental Labs

| Digital dentistry, Workflow

Digitalization has fundamentally transformed modern dentistry and dental technology. What once required physical impressions, stone models and manual craftsmanship can now be completed through fully digital workflows with remarkable precision and efficiency.

At the center of this transformation is CAD/CAM technology.

Today, CAD/CAM systems enable dental laboratories and practices to design and manufacture restorations faster, more consistently and with greater accuracy than ever before. Whether producing crowns, bridges, implant restorations, surgical guides or full-arch prosthetics, digital workflows have become an essential component of modern dental manufacturing.

This guide explains the fundamentals of CAD/CAM dental technology, outlines the complete digital workflow, reviews common CAD/CAM materials and compares chairside and laboratory solutions.

 

1. What is CAD/CAM in dental technology?

CAD/CAM stands for:

  • CAD (Computer-Aided Design) 
  • CAM (Computer-Aided Manufacturing) 

Together, these technologies enable dental restorations to be digitally designed and automatically manufactured.

CAD: The digital design process

The CAD component is responsible for creating the restoration virtually.

Using specialized dental software, technicians or clinicians can design:

  • Crowns 
  • Bridges 
  • Inlays 
  • Onlays 
  • Veneers 
  • Implant restorations 
  • Dentures 
  • Surgical guides 

The software converts scan data into a three-dimensional digital model and provides tools for designing highly accurate restorations.

Modern systems such as icam CAD software support:

  • Automatic margin detection 
  • Tooth libraries 
  • Occlusal analysis 
  • Contact optimization 
  • Implant workflows 
  • Full-arch design 

The result is a digital restoration ready for manufacturing.

CAM: The manufacturing process

Once the design is complete, CAM software generates the machining strategy.

The software determines:

  • Tool selection 
  • Milling paths 
  • Material parameters 
  • Machine movements 
  • Processing times 

The restoration is then produced automatically by a milling machine such as a coritec® CAD/CAM system.

The combination of CAD and CAM creates a seamless digital workflow from design to production.

2. Why CAD/CAM has become the standard

Several factors have driven the widespread adoption of CAD/CAM technology in dental laboratories.

Growing demand for efficiency

Patients increasingly expect:

  • Faster treatment times 
  • Fewer appointments 
  • Highly aesthetic restorations 
  • Digital workflows 

CAD/CAM technology supports these expectations while improving production efficiency.

Improved manufacturing precision

Digital workflows eliminate many variables associated with traditional methods.

Benefits include:

  • Consistent quality 
  • Accurate fits 
  • Reduced remakes 
  • Better documentation 
  • Predictable results 

Expanding material options

Modern CAD/CAM systems can process numerous materials with different clinical indications.

This flexibility allows laboratories to offer a broader range of restorations while maintaining efficient workflows.

3. The digital workflow step by step

The CAD/CAM workflow consists of several interconnected stages that transform patient data into a finished restoration.

Step 1: Digital scanning

Every digital workflow begins with data acquisition.

This may be performed using:

  • Intraoral scanners 
  • Laboratory scanners 
  • Model scanners 

The scanner captures the patient's dentition and creates a precise digital model.

Compared with conventional impressions, digital scanning offers:

  • Improved patient comfort 
  • Faster data transfer 
  • High accuracy 
  • Immediate verification 

The resulting file serves as the foundation for restoration design.

Step 2: Restoration design with icam

The scan data is imported into CAD software such as icam.

Here, the restoration is designed digitally.

Typical CAD functions include:

  • Margin identification 
  • Anatomical tooth design 
  • Occlusal adjustment 
  • Contact point optimization 
  • Implant library integration 
  • Automatic restoration proposals 

The software allows technicians to efficiently create highly detailed restorations while maintaining control over every design parameter.

Step 3: CAM strategy generation

After design approval, the restoration moves to the CAM stage.

CAM software converts the design into machine-readable instructions.

The software calculates:

  • Milling paths 
  • Tool movements 
  • Material-specific parameters 
  • Processing strategies 

Optimized CAM strategies help improve:

  • Surface quality 
  • Milling speed 
  • Tool life  
  • Restoration accuracy 

Step 4: Manufacturing with coritec

The finalized CAM file is transferred to the milling machine.

Modern systems such as the coritec® milling platform automatically manufacture the restoration from a selected material blank or disc.

Depending on the machine and material, production may involve:

  • Dry milling 
  • Wet milling 
  • Grinding 
  • Hybrid processing 

The milling process transforms the digital design into a physical restoration.

Step 5: Finishing and post-processing

After milling, additional processing may be required.

Examples include:

  • Zirconia sintering 
  • Lithium disilicate crystallization 
  • Staining and glazing 
  • Polishing  
  • Characterization  

The required finishing process depends on the selected material.

Step 6: Clinical delivery

The final restoration is inspected, finished and prepared for insertion.

The completed workflow provides a restoration that combines:

  • High precision 
  • Functional reliability 
  • Aesthetic quality 
  • Efficient production
