The Evolution of Dental Imaging Technologies—and the Role of AI

Updated: September 2026

Dental imaging has moved from film, to 2D digital sensors, to 3D CBCT, and now to AI that analyzes both 2D and 3D images. Each step improved detail and speed; AI adds consistency and real-time decision support. Here's the timeline and where AI fits.

Key takeaways

• Film gave way to 2D digital imaging (faster, lower dose), then to 3D CBCT (volumetric detail).

• More detail also means more data, which takes time and skill to interpret.

• AI overlays analysis on 2D and 3D images: real-time detection, automated measurements, and standardized reads.

• Overjet delivers FDA-cleared AI across the dental ecosystem, from practices to DSOs, education, and payers.

Imaging has always been the cornerstone of diagnosis and treatment planning. As the technology has evolved, so has its potential. Today, pairing AI with imaging systems is setting a new standard.

How has dental imaging evolved?

Traditional film radiographs

For years, film X-rays were the standard. They worked for basic assessments but were held back by slow processing, higher radiation, and inconsistent image quality. Interpretation also varied between providers, which made standardization hard.

Digital radiography (2D)

Digital imaging was a major leap: sharper images, lower radiation, and immediate viewing. Still, 2D digital imaging depends heavily on the clinician's subjective read.

3D imaging (CBCT)

Cone beam computed tomography (CBCT) brought volumetric imaging into everyday practice. It shows teeth, bone, nerve pathways, and other structures in detail, which is critical for implants, endodontics, orthodontics, and surgery. But that detail comes with far more data, which takes time and skill to interpret.

AI-powered imaging

Today, AI overlays analysis onto both 2D and 3D images. It supports real-time detection, automated measurements, and standardized decision support.

How does AI improve dental imaging?

AI analyzes X-rays in real time and surfaces clinically relevant findings directly on the image.

Key benefits:

• Real-time detection of caries and bone loss: AI flags potential pathology instantly

• Automated measurements: Clinically accurate periodontal bone-level assessments

• Visual overlays for patient communication: Annotated images help patients understand their diagnosis

• Standardized reads across providers: Consistent interpretation for every image

• Faster workflows: Quicker, objective analysis reduces chair time
