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

In recent years the CAD/CAM technology has revolutionized the dental field by introducing advanced digital tools for the design and fabrication of dental restorations. But what exactly does this mean and how does this system work? In this article we will explore the principles behind CAD/CAM technology and the benefits it offers dentists and patients.

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.
