De La Rosa Fig.1 13.5cm
Orthodontic contouring pliers designed for precise archwire shaping and controlled wire adaptation during fixed and removable appliance fabrication.
Key Features:
• Constructed from 440A surgical-grade stainless steel for strength and corrosion resistance
• 13.5cm overall length provides stable handling during detailed wire contouring
• Concave-and-convex beak configuration distributes forming pressure evenly across wire surfaces
• Three indexed grooves accommodate 0.016″, 0.018″, and 0.022″ wire sizes
• Chamfered jaw edges help reduce wire marking during bending procedures
• Suitable for wires up to 0.021″ × 0.025″ (0.55mm × 0.64mm)
• Precision box-joint hinge maintains consistent jaw alignment under repeated use
• Fully autoclavable at 134°C for routine clinical and laboratory sterilization
De La Rosa Fig.1 13.5cm
De La Rosa Fig.1 13.5cm measures 135mm in overall length and is constructed from 440A surgical-grade stainless steel with a high-polish mirror finish. The jaw assembly uses a precision-matched concave-and-convex beak configuration, one beak face hollowed into a U-channel, the opposing face rounded outward. This geometry distributes compression symmetrically around the wire cross-section, allowing archwire shaping without introducing axial torque. Three indexed grooves run across the inner jaw faces, sized at 0.016 inches (0.41mm), 0.018 inches (0.46mm), and 0.022 inches (0.56mm), confirmed in the close-up jaw thumbnails in the product image.
The grooves seat the wire at a fixed depth during each bend, preventing lateral drift along the beak surface. Chamfered edges on both jaw faces stop the contact zone from scoring the wire finish. The instrument handles wire up to 0.021″ × 0.025″ (0.55mm × 0.64mm). The box-joint hinge keeps both beaks in matched alignment under repeated load. De La Rosa Pliers in the Fig. 1 designation refer specifically to the grooved, non-spring version, distinguishing it from spring-loaded and smooth-tip variants in the same series. The instrument is fully autoclavable at 134°C.
Orthodontists use the De La Rosa Fig.1 13.5cm during fixed appliance therapy to contour stainless steel and nickel-titanium Dental Instruments archwires to patient-specific arch forms before bracket engagement. Orthodontic Pliers of this concave-convex design are also used by prosthodontists when forming C-clasps on removable partial denture frameworks and by lab technicians shaping heavy wires for functional appliances.
Leader Surgical brings documented manufacturing consistency to every instrument in its catalog, with material traceability and dimensional verification across each production batch, making this De La Rosa variant a dependable daily-use tool for both chairside and laboratory wire work.
What wire sizes is it compatible with?
While specifications can vary by manufacturer, this model typically handles:
- Round and Rectangular wires up to .021″ x .025″ (.055mm x .064mm).
- Grooved versions often feature three specific slots for wires sized .016″ (.41mm), .018″ (.46mm), and .022″ (.56mm).
