Weingart Plier
Angled orthodontic utility plier with cross-serrated beaks designed for secure archwire placement, removal, and posterior access across full arch applications.
Key Features:
• Surgical-grade stainless steel construction with passivated high-polish finish
• 145mm overall length for improved working distance from intraoral field
• Angled beak design (~32° offset) for enhanced posterior access
• Cross-hatched diamond serrations across full beak surface for secure wire grip
• Designed for round and rectangular archwires up to 0.030″ (0.76mm)
• Tapered beaks enable controlled engagement in molar tubes and bracket slots
• Suitable for archwire placement, removal, and distal wire adjustments
• Box-joint hinge ensures stable alignment and consistent grip performance
• Autoclavable at 134°C for standard clinical sterilization cycles
Weingart Plier
The Weingart Plier measures 145mm in total length and is built from surgical-grade stainless steel with a passivated, high-polish finish. The working beaks are slim and tapered, angling away from the handle axis at approximately 32 degrees; an offset geometry confirmed in the jaw profile diagram showing the curved terminal tip. The full beak face carries a cross-hatch serration pattern, machined in a diamond grid across the entire working surface. This cross-serration grips round and rectangular archwire up to 0.030 inches (0.76mm) securely from any approach angle, preventing wire rotation in the jaw during placement and removal strokes. The 14.5cm body length positions the operator’s hand further from the intraoral field than standard 13cm variants.
The angled tip accesses molar buccal tubes and posterior bracket slots where a straight-beak plier cannot align correctly with the wire path. The box-joint hinge with adjustment screw maintains jaw tension and tip alignment across extended clinical use. The spring-action handle separates the beaks between working strokes. weingart plier dental configurations with straight beaks are suited to anterior segments; this angled medium variant covers the full arch from canine to second molar in a single instrument. The instrument is fully autoclavable at 134°C.
Orthodontists use the Weingart Plier at each appointment for placing and removing archwires, threading wire ends into molar buccal tubes, seating wire into bracket slots across the arch, and bending wire ends distal to the last bracket. The Weingart Pliers 678-201 designation identifies this cross-serrated angled medium configuration as the international catalog reference standard.
Leader Surgical produces this instrument with verified 32-degree tip geometry and cross-serration depth tolerances, ensuring consistent wire grip and buccal tube access across every clinical session.
What wire sizes can they handle?
- Standard Weingart: Most models accommodate wires up to 0.030″ (0.76mm).
- Fine/Slim Tipped: These precision models are typically rated for lighter wires, often up to 0.022″ x 0.028″ (0.56mm x 0.71mm).
- Large Weingart: Heavier variants can sometimes grip wires up to 0.033″ (0.84mm).
