Evidence status: each field shows source quality, applicability, and review date. Research pending, information not established in reviewed sources, and vendor documentation pending are distinct outcomes.

Clinical fit

What this tool is for

Start with the authorized purpose, then verify how it fits your service line and reading workflow.

Exact purpose: Acorn 3D Software with Acorn 3DP Model provides modular image processing, visualization, segmentation, measurements, treatment planning, and three-dimensional models, including pedicle-screw trajectory planning for adult and pediatric thoracic and lumbar spine cases.

Intended users: Qualified dentists, dental radiologists, oral and maxillofacial surgeons, and trained dental imaging staff.

Care setting and population: Dental, oral and maxillofacial, hospital, and surgical-planning environments.

Workflow role: Dental image visualization, segmentation, measurement, implant or trajectory planning, and three-dimensional model support.

Required input: Supported dental CT, cone-beam CT, panoramic, cephalometric, or related radiographic data.

Output and human action: Three-dimensional models, measurements, planning views, templates, and reports for professional review.

Limitations: Planning outputs do not replace clinical examination or professional judgment; image quality, scan protocol, anatomy, manufacturing, and age or indication limits apply.

Regulatory identity

FDA record and catalog context

The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.

FDA submission: K251532

Modality: CT/CTA

Anatomy: Thoracic and lumbar spine, musculoskeletal, craniomaxillofacial, and vascular anatomy

Clearance type: 510(k)

Decision date: 2025-11-03

FDA status: FDA-cleared

Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration: Standards-based DICOM/PACS integration was identified in the FDA submission materials; compatibility with a specific PACS, RIS, EHR, or orchestrator requires confirmation.

Deployment and data flow: On-premise

Security and privacy: Vendor documentation pending

Training and support: Only qualified dentists, dental radiologists, oral and maxillofacial surgeons, and trained dental imaging staff should operate or interpret the product. Local onboarding should cover the exact release, supported population, limitations, failure examples, escalation, downtime, and competency documentation.

Monitoring and change control: Monitor by exact hardware, software, model, and algorithm version; patient population; anatomy; protocol; operator; input quality; output edits or overrides; failed studies; repeat acquisition or rework; downstream impact; downtime; incidents; recalls; and updates. Track these product-specific limits: Planning outputs do not replace clinical examination or professional judgment; image quality, scan protocol, anatomy, manufacturing, and age or indication limits apply.

Release and scope verification

Map installed model, build, options, population, anatomy, inputs, outputs, and enabled functions to K251532 before acceptance.

Clinical acceptance

Use a signed local test set for the supported population and workflow. Include common and difficult cases, exclusions, acquisition variation, failed or low-quality inputs, reviewer overrides, and downstream effects. Planning outputs do not replace clinical examination or professional judgment; image quality, scan protocol, anatomy, manufacturing, and age or indication limits apply.

Evidence

Performance evidence

Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.

Evidence summary: The exact FDA decision material describes Acorn 3D modules, Acorn 3DP Model output, trajectory automation, and expert review. The public package does not establish a universal planning accuracy or patient-outcome claim.

Reported sensitivity: Not applicable

Reported specificity: Not applicable

No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.

Economics and lifecycle

Budget and ongoing governance

These are common procurement questions; unknown values remain visible until a source supports them.

Pricing and total cost: Not established in reviewed sources

Reimbursement and coding: No separate named-product Medicare payment was identified in the reviewed CMS coverage material. Evaluate the product within the applicable imaging, procedural, or surgical service line and verify payer, site-of-service, and coding assumptions independently.

Safety and lifecycle

Postmarket record

Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.

Postmarket safety review: The 2026-09-02 openFDA device-recall snapshot contained no record matched to K251532 by exact native submission identifier. This does not exclude product-family, later, or adverse-event information.

Buyer worksheet

Open questions to take to the vendor

Verify security and privacy controls: Public materials reviewed for this exact release do not establish the complete security posture. Request data-flow, identity, audit, encryption, retention, remote-access, vulnerability-management, backup, and incident-response evidence.
Verify pricing and total cost: No public list price for the exact cleared configuration was found. Obtain a written quote separating hardware or license basis, implementation, interfaces, infrastructure, training, service, upgrades, renewal, consumables, and exit costs.

Recovered from the prior exact-submission extraction and normalized under the current provenance rules. Exact-name and exact-submission searches in the checked 2026-09-01 indexes returned no PubMed records and no ClinicalTrials.gov records for K251532; review status is candidate_review_pending. Any candidate literature or registry record remains quarantined as product-family evidence unless exact submission and version linkage is established. Current vendor material is product-family context. Pricing, complete security architecture, contracted deployment, exact reimbursement, and local interoperability remain unverified. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.

Candidate leads remain unpublished until a human confirms the exact product and tested version.
