Orthodontics
Start here — the six simulators every ortho question comes back to: tooth movement, anchorage, wire mechanics, friction, and aligners.
Featured
Tooth-Movement Simulator
Watch a tooth move through a validated periodontal-ligament model. Center of resistance, M/F ratio, live PDL stress, root-resorption risk, and crown/apex paths — tipping vs bodily movement from first principles.
Open simulator →
Multi-tooth
Anchorage Simulator
Retract a canine and watch the anchor unit drift forward by Newton's third law — inversely to root-surface resistance. Reinforce with more teeth or a skeletal TAD and see the loss drop to zero.
Open simulator →
Parametric
Closing Loop Designer
T-loop, L-loop, and vertical closing loops. Adjust gable bends, wire, height, and position — see the force, load-deflection rate, and M/F ratio update live.
Open simulator →
Sliding mechanics
Friction & Binding Calculator
Net tooth-moving force after friction. Cross the critical contact angle and watch binding consume the force — wire, ligation, angulation, and saliva all live.
Open simulator →
3D · parametric
Two-Bracket Simulator
Two teeth, two 0.022 slots, one wire. Change interbracket distance, wire size/material, and each tooth's inclination — watch the wire deflect and the force system update live in 3D.
Open simulator →
Aligners
Aligner Attachment Simulator
Can the bare aligner express a movement — or does it need an attachment? A reduced-order shell–crown contact model delivers the force, decays it over wear time, and finds the minimal attachment when one is needed.
Open simulator →
Research & R&D
For manufacturers and researchers — materials testing, ML surrogates, patient-specific geometry, and a live literature feed.
R&D · ISO 15841
Materials Testbench
For wire manufacturers: define a superelastic alloy (or fit it to your measured three-point-bend curve), run a virtual ISO 15841 test, and translate material properties into the clinical force system delivered.
Open simulator →
Virtual lab
Materials Testing Lab
Tensile stress-strain, 3-point bend, fatigue (S-N), and custom-geometry 2D FEA — driven by the cited property database. NiTi's superelastic plateau, springback, yield, and a real browser finite-element stress field.
Open simulator →
Research · ML
Surrogate Model Sandbox
Sweep a physics engine to build a dataset, then train a small neural network in-browser to predict it. Watch the surrogate's surface converge to the true physics, live, with R² → 1.
Open simulator →
Patient geometry
Patient Arch Simulator
Upload an upper/lower STL scan (or use the demo arch) and view it in 3D with bracket markers. The full-arch archwire force system and per-tooth side-effects are built on top of this.
Open simulator →
Live · Europe PMC
Live Literature
An "alive" library: search the latest findings live from Europe PMC (PubMed/MEDLINE + open access), filter to reputable journals, save papers, and watch topics for new publications since you last looked.
