Core solvers

OFS + VBFS: two engines, one root‑based plan

Building on our technical heritage from the first development and clinical application of the Root‑Crown System (RCMS) in 2017, we independently developed two core solvers. Both enable personalized computation based on the true center of resistance and biomechanical characteristics of each tooth in every case.

SOLVER 01

OFS — Orthodontic Force Solver

A rapid orthodontic force solver based on an integral algorithm. Maps center of resistance → movement type → the required force system for every tooth, in seconds.

Full‑arch force systems computed in under a second
Personalized per‑tooth input from CBCT + scan data

SOLVER 02

VBFS — Voxel‑Based FEM Solver

A mechanical solver based on the voxel finite‑element method. Models teeth, roots and bone together to produce stress fields and safe movement envelopes.

Root, bone and aligner modelled as one system
Outputs movement boundaries, not just force magnitudes

RCMS 3.0

Root‑Crown Maxilla‑Mandible‑Jaw System

RCMS 3.0 reconstructs the full dentition in 3D — integrating CBCT root and bone data with intraoral crown scans into one tooth‑bone‑jaw model, and defining safe movement boundaries for each root.

Full visualization of root & bone data with comprehensive risk alerts
Full quantitative analysis — quantified root‑bone harmony for safe, stable final results
Full customized biomechanics — personalized CR positioning plus full force‑system evaluation, higher plan expression

Anatomical guardrails

Where teeth may — and may not — move

Nerve canal safety boundary visualization — **Nerve canal** — clear safety boundary & efficient movement route

Cortical bone thickness heat map — **Cortical bone heat map** — inner/outer plate thickness at a glance

3D heatmap of planned tooth movement — **CR point & condyle position** — actual resistance centers via FEM

Root‑oriented treatment planning & accurate execution: maxillary sinus, condyle position and cortical‑bone limits are checked on every plan — reducing risks such as dehiscence, fenestration and root resorption.

ACE 3.0

3D Cephalometric Measurement System

Instantly preview cephalometric data of the final simulated treatment outcome — before a single aligner is made. Automatic landmark detection ends manual tracing; the cloud platform needs no local install.

Eliminate time lag — real‑time preview of post‑correction cephalometric indicators in the plan
Eliminate alignment errors — removes diagnostic deviation from model pre‑processing alignment (torque et al.)
Bridge the experience gap — visual measurement results support assessment of reasonable, accurate treatment targets

Efficient chairside communication — STL data compatible: 3‑min import, 3‑sec virtual alignment

Instant plan comparison — simulate diverse plans to address patient concerns

User‑friendly measurement tools — 3D editable design with multiple orthodontic measurements

No more model errors — precise movement gauge; final simulation reflects clinical reality

ART²

Anytime Re‑Treatment Achievement Rate Table

ART² utilizes 3D digital model superimposition across treatment stages to comprehensively evaluate tooth movement and rotation throughout treatment — qualitative and quantitative.

Color‑coded qualitative display of tooth movement — intuitive to view
Quantitative analysis of movement data & expression rate for superior accuracy
3D viewing mode — sagittal, transverse and vertical directions for faster follow‑up
Review tracking that flags drift before it requires correction

Material science

MagicMove® — the data behind the comfort

Corrective force over 14 days of wear

MagicMove® vs conventional PETG / TPU monolayers

MagicMove multilayer film structure — Hard–soft–hard composite: medical‑grade TPU + PETG co‑extrusion

Hard–soft–hard composite film structureThe multi‑layer composite is co‑extruded from medical‑grade TPU and PETG. Its robust high‑molecular chains resist fracture, while a marginally lower elastic modulus greatly improves comfort.
Force inside the windowPrecisely applied ideal orthodontic force helps reduce the risk of root resorption from overly strong initial force — and poor results from inadequate force in later stages.
Yield strength & toughnessHigh yield strength and toughness give the film superior anti‑tear performance and reduce the breakage rate of aligners.
Validated at scaleMagicMove materials have been developed for years and proven by 200,000+ treatments. A next‑generation multi‑layer composite is in clinical testing.

Digital manufacturing

We make what we design

A fully automated, 10‑step digital production line — from print path to sealed unit — delivers aligners of consistent premium quality. Shipments now run from our new Shaoxing Intelligent Manufacturing Center.

Automated 10‑step line

Digital, auditable production — consistent premium quality on every unit, not just the first batch.

Laser cutting — SMC 3.0

Robotic laser trimming follows the gingival margin with a ~0.03 mm spot: smoother edges, less polishing, more comfort.

Shaoxing smart factory

Our intelligent manufacturing center in Shaoxing, Zhejiang — purpose‑built for clear‑aligner production at scale.

Also in development: JMCA — the Temporomandibular Joint Motion Trajectory Capture and Analysis System, extending digital diagnosis from static anatomy to jaw function.

One integrated loop — diagnosis to delivery

Diagnosis → assessment → planning → manufacturing → monitoring. Each module feeds the next, so the plan you design is the one that gets made and tracked.
