The Hyrax Expansion Screw is a clinically proven orthodontic device designed for precise mid-palatal suture separation in fixed appliance treatments. Engineered for reliability and efficiency, this stainless steel screw enables controlled palatal expansion to correct crossbites, narrow arches, and skeletal discrepancies. As a core component of modern dental orthodontic expansion screw systems, it integrates advanced safety and functionality features tailored for both orthodontists and lab technicians.
Key Structural Innovations:
Built-In Safety Stops: Automatically lock the screw at maximum expansion (indicated by a laser-etched arrow), preventing over-expansion or accidental disassembly.
Break-Resistant Retention Legs: Reinforced stainless steel legs ensure stable guidance throughout the entire expansion process.
Anti-Retraction Spindle: Integrated friction technology eliminates unwanted backward rotation, maintaining consistent expansion force.
Compact Design: Achieves maximum expansion range with minimal intraoral footprint, enhancing patient comfort.
Solder-Free Construction: Reduces corrosion risk and simplifies sterilization workflows.
Included with each screw is a dedicated safety key, ensuring secure activation and precise control during adjustments.
Material: Medical-grade stainless steel (ISO 13485 certified).
Models: 8mm / 9mm / 11mm / 13mm expansion capacities.
Packing: 1 screw
Compliance: CE-marked
✅ Precision Control
Permanent laser-marked directional arrow ensures accurate activation alignment.
Tie-Down Ready: Secure fixation once desired expansion is achieved, preventing relapse.
✅ Durability & Safety
Resists mechanical stress during chewing or speech.
Biocompatible material eliminates allergic reactions.
✅ Efficiency in Practice
Pre-assembled design reduces chairside preparation time.
Compatible with all standard orthodontic kits and archwire systems.
Installation: Bond the Hyrax screw to maxillary molars using stabilizing bands.
Activation: Use the safety key to turn the screw daily (as prescribed), guided by the laser arrow.
Monitoring: Built-in stops halt expansion at the predefined limit, while anti-retraction mechanics stabilize progress.
Post-Expansion: Lock the screw with ligature wire and transition to retention proto
Proven Outcomes: Trusted by clinics globally for predictable mid-palatal expansion.
Streamlined Workflow: Ready-to-use packaging eliminates pre-sterilization steps.
Adaptable: Pair with ceramic bands or clear aligners for aesthetic-focused treatments.
