How we get it right.
Every cutaway is built from published dimensional data: the manufacturer's own CAD when we have it, otherwise IFUs, product catalogs, and ISO/ASTM geometry. We match the taper, the thread profile, and the connection geometry to the source specification — and where the source doesn't reach, we say so, on the model itself.
Standards we work to
- ISO 14801
- Dynamic fatigue testing of endosseous implants — the load geometry that makes the abutment–implant connection the part worth getting right. Our section planes and seat mechanics follow the joint this standard stresses.
- ASTM F67
- Unalloyed (commercially pure) titanium, Grades 1–4. Most implant bodies are Grade 4 CP-Ti; we model and label fixture material accordingly.
- ASTM F136
- Wrought Ti-6Al-4V ELI — the alloy of most abutments and abutment screws, where preload and fatigue strength matter more than osseointegration surface.
- Material distinctions
- Grade 4 CP-Ti vs Ti-6Al-4V ELI vs TiZr: different parts of the same joint are different metals for different reasons, and the cutaway's part labels keep them distinct.
The build
- 01
Source
Your CAD (STEP, SLDPRT, IGES) — or the physical parts, calipers, and the published IFU. Every dimension we model traces to one of these.
- 02
Solid parts
Fixture, abutment, and screw are modeled as separate watertight solids at true scale in millimetres — including the internal geometry: the bore, the threads, the conical seat, the index.
- 03
Dimensional check
Cone angle, platform diameters, thread pitch, hex across-flats — each checked against the source value before the model ships. The numbers shown beside the viewer are the numbers the geometry is built to.
- 04
Live sectioning
The viewer cuts the solids in the browser, in real time — the cross-section you drag through is the actual modeled geometry, not a pre-rendered image. If the model were wrong, sectioning would expose it. That's the point.
- 05
Annotation
Parts are named in the clinical lexicon — conical seat, anti-rotation index, platform switch, implant–abutment junction — with each key dimension tagged to its source.
The limits, stated
Where a manufacturer's exact internal geometry is proprietary, we model to published tolerances and flag every assumption— you can read the full list on each demo's “Modeling assumptions” panel. An archetype is labeled an archetype. A named system's exact internal geometry is reproduced only from that manufacturer's own CAD or IFU, under agreement.

The line we don't cross
These are chairside education tools. They support — never replace — your regulated IFU, and they make no clinical claims. Your regulatory position inherits nothing from us.
