Orthodontic practices that rely on CBCT scans for treatment planning now have a new AI-powered option with full regulatory backing. Orca Dental AI announced in March 2026 that its CephX platform received FDA clearance for 3D imaging, making it the only orthodontic AI diagnostic support platform cleared for both 2D and 3D analysis.

What Happened

The FDA granted Class II 510(k) clearance (K252538) for CEPHX3D, Orca Dental AI's 3D imaging module. The clearance covers AI-powered CBCT segmentation of the mandible, maxilla, full dentition, and the inferior alveolar nerve, along with linear, angular, and volumetric measurement tools.

This builds on the company's initial 2D clearance (K231396), granted in January 2024 for CephX's cephalometric analysis capabilities. In that submission, the platform demonstrated 99% landmark accuracy within a 2mm margin compared to three experienced orthodontic specialists.

Alongside the 3D clearance, Orca also announced new integrations with DEXIS DTX Studio and Greyfinch, embedding CephX directly into two widely used imaging and practice management platforms. The company had previously integrated with SOTA Cloud and Cefla.

Why It Matters for Your Practice

Three things stand out for orthodontic practices evaluating AI imaging tools.

Unified 2D and 3D analysis in one platform. Most AI imaging tools specialize in either 2D cephalometric analysis or 3D CBCT workflows. CephX now handles both under a single FDA-cleared umbrella, which simplifies vendor management and reduces the number of tools your team needs to learn.

Growing integration ecosystem. CephX's expanding list of integrations, including DEXIS, Greyfinch, and SOTA Cloud, means the AI analysis can run inside platforms your team may already use. That reduces friction compared to standalone tools that require separate uploads and logins.

Speed gains in treatment planning. A peer-reviewed study comparing CephX and WebCeph to Dolphin Imaging found that AI-assisted cephalometric tracing (with clinician landmark correction) reduced analysis time by 46%. For practices managing high patient volumes, that time savings compounds quickly across a full schedule.

The broader trend is worth noting too. A 2025 PMC review cataloged 29 FDA-cleared AI products across 13 dental imaging companies, covering everything from caries detection to 3D segmentation. The orthodontic AI space is maturing fast, and regulatory clearance is becoming table stakes rather than a differentiator.

TMR Take: This clearance is a meaningful milestone for Orca Dental AI, but the real story is what it signals for the market. Orthodontic practices are moving toward integrated, AI-assisted imaging workflows. CephX's dual 2D/3D clearance and expanding integrations position it well, though practices should still evaluate based on their specific imaging hardware and PMS ecosystem. The best tool is the one that fits your existing workflow.

What to Do Now

If your practice uses CBCT imaging for orthodontic planning, here are concrete next steps:

  1. Audit your current imaging workflow. Map how long cephalometric analysis and 3D treatment planning take today. That gives you a baseline to measure any AI tool against.

  2. Check integration compatibility. If you use DEXIS DTX Studio or Greyfinch, CephX now integrates directly. If you use a different imaging platform, check whether CephX's cloud-based upload workflow fits your needs.

  3. Request a trial. CephX offers a free trial through their website. Test it with your own CBCT scans before committing, and compare the AI-generated analysis to your manual workflow.

  4. Compare alternatives. CephX is not the only player in this space. Review our guides to dental AI software and orthodontic software to see how it stacks up.

The Bottom Line

Orca Dental AI's FDA clearance for 3D imaging through CephX marks a step forward for AI-assisted orthodontic diagnostics. For practices already using CBCT, the combination of 2D and 3D analysis in a single cleared platform, paired with integrations into DEXIS and Greyfinch, is worth evaluating. The orthodontic imaging landscape is consolidating around AI-powered workflows, and staying informed on your options is the first step toward a more efficient practice.
