CAD/CAM technology in dentistry: what it means and how it works

What CAD/CAM means

The acronym CAD/CAM is derived from the English Computer-Aided Design e Computer-Aided Manufacturing. In dentistry, it indicates the use of digital software and machinery to:

• Design Dental restorations such as crowns, veneers, bridges and inlays.
• Produce these artifacts with extreme precision by milling or 3D printing.

In practice, CAD/CAM replaces much of the manual laboratory work with digitized processes, increasing speed and accuracy.

How CAD/CAM technology works

The process consists of several main steps:

1. Digital acquisition - the dentist uses a intraoral scanner to take an impression of the mouth, avoiding traditional impression pastes.
2. CAD design - the digital model is processed with specific software, which allows the restoration to be custom-designed.
3. CAM Production - the digital file is sent to a milling machine or 3D printer that makes the artifact from ceramic, zirconia, or other materials.
4. Clinical application - the restoration is finished, checked, and cemented onto the patient's tooth.

The advantages of CAD/CAM technology

This technology offers many benefits over traditional methods:

• High accuracy → Perfect fit of the restoration to the natural tooth.
• Reduced time → In many cases it is possible to obtain a crown in a single session.
• Patient comfort → No more invasive impressions with troublesome pastes and materials.
• Durability and quality → innovative materials such as zirconia and high-strength ceramics.
• Clinical efficiency → Simplification of workflow for dentist and laboratory.

Applications in dentistry

CAD/CAM technology is used for a variety of treatments, including:

• Dental crowns and bridges.
• Inlays and onlays.
• Aesthetic veneers.
• Prosthetic structures on implants.
• Customized orthodontic appliances.

La CAD/CAM technology in dentistry represents a huge step forward toward more precise, faster, and comfortable clinical practice. With digital design and manufacturing, patients can benefit from high-quality custom restorations, while practitioners optimize time and results. It is one of the innovations that best demonstrate how digital is improving oral health and the dental office experience.
