Why Choose Leone POP Expansion Screws?
Orthodontic expansion remains one of the most important procedures in interceptive and functional orthodontics. Choosing a reliable expansion screw directly impacts treatment predictability, patient comfort, and laboratory efficiency. POP Expansion Screws by Leone are designed to provide controlled, biomechanically sound expansion for both upper arch and universal applications.
This article explains what makes POP screws unique, their benefits, and why they are an excellent choice for dental laboratories and orthodontists.
What Are POP Expansion Screws?
POP expansion screws are orthodontic devices embedded in removable or fixed appliances to gradually widen the dental arch. By activating the screw, clinicians apply controlled forces that promote skeletal and dental expansion.
Leone developed the POP screw line to combine precision mechanics, ergonomic handling, and predictable expansion, making them suitable for modern orthodontic workflows.
Key Features of Leone POP Screws
1. Advanced Techno Polymer Body
The screw body is manufactured using a biomedical techno polymer, offering:
- High mechanical resistance
- Lightweight structure
- Excellent compatibility with orthodontic acrylics
- Improved durability during activation cycles
This material ensures reliable performance while keeping appliances comfortable for patients.
2. Biomedical Stainless Steel Mechanism
The internal screw mechanism is made from biomedical stainless steel, providing:
- Smooth and precise activation
- Long-term resistance to corrosion
- Consistent force transmission
- Reduced risk of mechanical failure
This combination of polymer body and steel mechanism delivers optimal strength and reliability.
3. Self-Centering Rectangular Guides
One of the most innovative features of POP screws is the self-centering rectangular guide system, which ensures:
- Controlled and symmetrical expansion
- Reduced risk of screw displacement
- Predictable biomechanical performance
- Improved treatment outcomes
This feature is particularly important for achieving consistent results in rapid palatal expansion and removable appliances.
4. Embedded Direction Arrows
Two embossed arrows on the screw body clearly indicate the direction of activation. This provides major advantages:
- Easy identification during laboratory fabrication
- Clear instructions for clinicians and patients
- Reduced risk of incorrect activation
When used with acrylic similar in color to the polymer body, the included white arrow helps keep the activation direction visible.
5. Available in Multiple Colours
POP screws are available in Six colours:
Colour coding helps laboratories organize appliances efficiently and allows clinicians to easily identify appliance types.
Benefits for Dental Laboratories
Using POP expansion screws simplifies appliance fabrication:
- Precise placement thanks to the plastic holder
- Protection of screw holes during acrylic packing
- Easy removal after curing
- Consistent integration into orthodontic appliances
These features reduce chairside adjustments and streamline lab workflows.
