1. Introduction
Dear valued user,
Thank you for choosing Relu® Automate — our AI-powered software platform built to help dental professionals deliver faster, more scalable, and more consistent care. Your decision to use our technology marks an important step in the digital transformation of dentistry, where automation and precision work hand in hand.
At Relu, we are committed to reshaping dental workflows through intelligent software. Relu Automate enables dental labs and clinicians to streamline their design processes using artificial intelligence and rule-based logic. The platform automatically processes intraoral scans, CBCT data, and facial scans to generate printable outputs such as dental models, wax-ups, bleaching trays, occlusal appliances, and more — all with minimal manual intervention.
Each design workflow is structured as a modular recipe, representing a specific task (e.g., segmentation, model builder, bracket removal, bite correction). These recipes come with preset configurations that users can adapt to meet specific clinical or lab protocols, allowing for rapid, repeatable, and high-quality results.
Relu® Automate is a cloud-based solution, meaning no software installation or special hardware is needed. The interface is accessible via a secure web portal, with role-based user permissions, audit trails, and encrypted data transfer to ensure safety and compliance. Credits are only consumed upon case submission, and our refund policy ensures that you only pay for clinically valuable outcomes.
To further support performance and collaboration, the platform includes built-in quality control tools: an interactive 3D viewer, sculpting interface, model inspection features, and secure file-sharing capabilities — all compatible with additive manufacturing workflows.
Whether you're scaling your lab’s output or adopting in-house 3D workflows in a clinic, Relu®Automate adapts to your needs. We’re proud to support your journey toward intelligent dental design — and we’re here to be a trusted partner every step of the way.
Thank you for choosing Relu.
Sincerely,
The Relu Team

2. IMPORTANT INFORMATION
This manual was created by Relu BV. It is intended to guide users in the correct and safe use of Relu® Automate, a software-as-a-service (SaaS) platform for AI-powered dental design and planning.
For technical support or questions, you may contact Relu directly at [email protected]
Website: relu.ai
2.1 Warnings and precautions
⚠️ Please read the following carefully before using Relu Automate:
2.1.1 General warnings
Relu® Automate does not replace clinical judgment. All outputs must be reviewed and validated by a qualified dental professional prior to clinical application or manufacturing.
Do not use Relu® Automate for diagnostic purposes or as the sole basis for treatment decisions. It is a planning and design aid only.
Do not use outputs without review. Automated results should always be inspected in the 3D viewer prior to use or export.
2.1.2 Cybersecurity and access
Each user must log in with their own personal account. Shared logins are prohibited and may compromise data security and traceability.
Use strong, unique passwords and a secure password manager.
Do not upload patient-identifiable data unless proper anonymization and data protection procedures are in place in accordance with GDPR and HIPAA (where applicable).
2.1.3 System use and limitations
If a file is incorrectly processed (e.g., segmentation error, alignment failure), you may request a refund, but only if the output is clinically unusable and would not save the user any time compared a non-automated CAD workflow.
Processing accuracy depends on the quality of input data. Incomplete or low-resolution scans may reduce performance.
Visual inspection is mandatory to ensure correct output results.
The software does not support real-time intraoral scanning or chairside integration. It is designed for asynchronous planning workflows.
2.1.4 Output responsibility
It is the user’s responsibility to ensure that files exported from Relu Automate are validated before manufacturing (e.g., 3D printing or CNC trimming).
We recommend that you check the limitations of your 3D printer or CNC mill hardware and to set the output parameters in Relu® Automate accordingly.
