OrthoTruss Education

Choose a case. Explore the mechanics.

Start with a guided decision, investigate a simulator, or open an advanced tool. Each route states its intended level.

FPD remains the biomechanics workspace: full instruments, parameters, comparisons and research tools. Education connects you to the same tools with a learning path.

Start a guided case

For learners with basic orthodontic knowledge. Predict an effect, reveal the initial response, then adjust the design.

Clinical roundEducation

Stop crown-first tipping

Learners & clinicians · Applied mechanics

Move crown and root together initially instead of accepting a crown-first response.

Educational mechanics; initial response only Related learning →
Clinical roundEducation

Make the root lead

Learners & clinicians · Applied mechanics

Increase root control until the root leads the initial response.

Four First Premolar Extraction — Class I Bimaxillary Protrusion

Learners & clinicians · Applied mechanics

Coordinate maximum-anchorage retraction of both arches to reduce bimaxillary dentoalveolar protrusion and improve the lip profile, keeping upper/lower retraction balanced so the molar relationship stays Class I and the midlines coincident.

Educational scenario; not a patient-specific treatment plan Related learning →
Clinical scenarioEducation

Asymmetric Extraction — Midline Correction

Learners & clinicians · Applied mechanics

Shift the upper anterior segment toward the deviated side to correct the dental midline, using differential left-vs-right anchorage and asymmetric force systems while avoiding a new posterior or molar asymmetry.

Clinical scenarioEducation

Class III Camouflage — Lower-Arch Extraction

Learners & clinicians · Applied mechanics

Retract and retrocline the lower anterior segment (and often procline the uppers) to correct the incisor relationship and camouflage a mild-to-moderate skeletal Class III, staying inside the lower-incisor inclination limit set by the labial alveolar bone.

Educational scenario; not a patient-specific treatment plan Related learning →
Clinical scenarioEducation

Lower-Only First Premolar Extraction — Single-Arch Decision

Learners & clinicians · Applied mechanics

Relieve lower crowding / retract the lower labial segment using lower-only premolar extraction, while planning the lower anchorage so the buccal occlusion finishes in an agreed relationship despite the unmatched upper arch.

Educational scenario; not a patient-specific treatment plan Related learning →
Clinical scenarioEducation

Four Second Premolar Extraction — Minimum / Moderate Anchorage

Learners & clinicians · Applied mechanics

Close the second-premolar extraction spaces mainly by mesial movement (protraction) of the posterior segments, preserving incisor position in a minimum/moderate-anchorage case where little anterior retraction is wanted.

Educational scenario; not a patient-specific treatment plan Related learning →
Clinical scenarioEducation

Molar Loss + Contralateral Compensating Extraction — Asymmetric

Learners & clinicians · Applied mechanics

Close the edentulous molar space by protracting the posterior teeth forward into the site while a contralateral compensating extraction balances the arch, keeping the midline centred and the occlusal plane level despite the built-in left-right asymmetry.

Educational scenario; not a patient-specific treatment plan Related learning →

Explore a simulator

For students and clinicians comfortable with force and moment. Change one variable and inspect the model assumptions.

SimulatorFPD

Combined Mechanics

Clinicians & researchers · Applied mechanics

Compose wires, elastics, and skeletal anchorage, then attribute the superposed response tooth by tooth.
