Digital dentistry is not a single technology — it is an integrated workflow that connects multiple digital tools into a seamless process. Understanding how each component fits together is essential for clinicians who want to leverage the full potential of digital technology.

Intraoral Scanning

The digital workflow begins with data capture. Intraoral scanners replace conventional impression materials with optical scanning, producing a highly accurate three-dimensional digital model of the dentition. Modern scanners achieve accuracy levels of 10–20 microns, which is comparable to or better than conventional impressions for most clinical applications.

CBCT Integration

For implant cases, intraoral scan data is merged with cone beam CT data to create a comprehensive three-dimensional model that includes both the surface anatomy and the underlying bone structure. This merged dataset is the foundation for digital implant planning.

Digital Treatment Planning

Implant planning software allows the clinician to virtually place implants in the optimal position, taking into account bone volume, proximity to anatomical structures, and the desired prosthetic outcome. The prosthetic-driven planning approach — starting with the desired tooth position and working backward to determine implant placement — is the gold standard.

Surgical Guide Fabrication

The digital treatment plan is used to design a surgical guide that constrains the drill to the planned implant position. Guides can be tooth-supported, mucosa-supported, or bone-supported, depending on the clinical situation. Fully guided surgery — where both the direction and depth of the osteotomy are controlled — provides the highest level of accuracy.

CAD/CAM Prosthetics

Computer-aided design and manufacturing (CAD/CAM) technology allows prosthetic restorations to be designed digitally and milled or printed from high-quality materials. Zirconia, PMMA, and composite resin are the most commonly used materials for CAD/CAM restorations.

The fully digital workflow — from scan to restoration — reduces chair time, improves accuracy, and enables better communication between the clinical and laboratory teams. As the technology continues to mature, the barriers to adoption continue to fall.
