Twin Blocks
printed in-office.

Twin Blocks remain a reference for Class II growth modification when timing is optimal. Their effectiveness in mandibular advancement is significantly enhanced by digital design and manufacturing.

  • 01Precise bite construction based on skeletal analysis and growth prediction.
  • 02Controlled block angulation for optimal mandibular repositioning.
  • 03Customizable thickness and coverage to meet vertical dimension needs.
  • 04Built-in expansion option for transverse correction when indicated.
  • 05Reproducible design for replacements during growth spurts.

Mandibular advancement
with aligners.

A modern alternative for growing patients. Mandibular advancement aligners combine growth modification and alignment in selected indications — esthetic, comfortable, and with strong compliance.

  • 01Controlled progressive advancement, integrated into aligner stages for gradual skeletal adaptation.
  • 02Dental alignment and growth modification handled in parallel for optimal efficiency.
  • 03Enhanced vertical control in hyperdivergent cases, with fine-tuned management of molar extrusion.
  • 04Strong patient acceptance: esthetic, comfortable, removable — especially among adolescents.
02 · Why go digital

Precise design,
for clinical predictability.

Digital workflows deliver a level of biomechanical control and reproducibility that conventional lab methods cannot easily match.

Precise advancement planning

Exact mandibular construction setup and biomechanical planning tailored to each patient's skeletal pattern and growth potential.

Short turnaround, easy reprints

Fast production and the ability to reprint appliances during growth — uninterrupted treatment continuity.

Better biomechanical control

Reduce unwanted dental compensations through precise control of angulation, thickness, and force vectors.

More consistency and predictability

Digital manufacturing reduces lab variability and delivers high-quality, reproducible appliances case after case.

03 · Clinical strategy

A clinical strategy,
not just a tool.

Digitally designed functional appliances are a clinical strategy built by orthodontists, for orthodontists — a competitive edge that strengthens skeletal precision and outcome predictability.
