Precision.
Transparency.
Control.
At ARC, we design every treatment using OnyxCeph³™, a high-end orthodontic planning software trusted by labs and specialists worldwide. With OnyxCeph, we give you full visibility into your case, custom control over movements, and confidence in predictability.
Why OnyxCeph Should Matter to You
With OnyxCeph, we give you full visibility into your case, custom control over movements, and confidence in predictability.
In selecting our planning platform, we prioritized three pillars:
Independence & Flexibility
OnyxCeph is not tied to any proprietary aligner system. That means we can adapt each case to your clinical philosophy and biomechanics.
Advanced Diagnostic Depth
From cephalometric tracing and skeletal overlays to full 3D model analysis, OnyxCeph gives a deep, integrated view of your patient’s dentofacial structure.
Precision & Control
You gain the ability to review every tooth movement, attachment, auxiliary, and force vector before fabrication — not after.
At ARC, we combine your clinical intent with OnyxCeph’s precision tools to deliver aligner plans you trust.
Key Features & Capabilities
3D Model Segmentation & Alignment
-
Automated and manual tooth segmentation
-
Control over arch curves, base planes, midline and coordinate systems
-
Collision detection to prevent tooth overlaps or impossible interferences
Cephalometric & Superimposition
-
Import 2D cephs or CBCT data, overlay tracing and landmarks
-
Combine skeletal diagnosis with aligner planning
-
Superimpose stages or finalize models for growth or stability analysis
Stage-by-Stage Movement Design
-
Incremental staging with customizable step sizes
-
Fine control of individual tooth trajectories (rotation, translation, torque)
-
Ability to split or group movements (vector coordination between teeth)
Attachments, Auxiliaries & Elastics
-
Custom attachment geometry (size, shape, orientation)
-
Plan auxiliaries (elastics, buttons, mini-screws) and simulate their effect
-
Integrate attachments and auxiliaries
Occlusion & Collision
Analysis
-
Real-time visualization of occlusal contacts
-
Root proximity & collision warnings
-
Soft tissue envelope checks (to avoid gingival interference)
Plan Validation & Safety Checks
-
Automatic movement-limit constraints
-
Force safety and biomechanical feasibility warnings
-
Feasibility validations before finalizing the plan
ARC + OnyxCeph Workflow
01.
You submit the scan & records (intraoral scan, bite registration, photos, CBCT if available)
02.
ARC imports into OnyxCeph, orients coordinate systems, prepares baseline model
03.
Technician & orthodontist co‐design the plan with full staging, attachments, auxiliaries
04.
You receive the full 3D preview for review and approval
05.
We manufacture the aligners, deliver them with a case packet (instructions, progress maps, refinements)
06.
Optional refinement cycle using the same OnyxCeph plan as foundation
Turnaround time for review typically takes X business days (you can set your standard).
