Tweed Loop Plier 13cm

Tweed Loop Plier 13cm

The Tweed Loop Plier 13cm measures 130mm in overall length and is built from surgical-grade stainless steel with a high-polish finish. The jaw profile is the defining structural detail: both beaks terminate in a broad, flat rectangular face; wider than the beak shaft, creating a mushroom-shaped tip profile, as shown clearly in the jaw diagram. This wide flat contact surface distributes compressive force evenly across the wire face during loop closure, preventing wire rotation and localized deformation at the bend site. The instrument handles square and rectangular archwire up to 0.022″ × 0.028″ (0.56mm × 0.71mm).

Unlike cylindrical-beak Tweed variants used for helical loop winding, this flat-jaw design grips the wire segment laterally, holding it flat between two parallel rectangular faces. The lap-joint hinge keeps both flat beak faces in full-surface contact alignment under compression load. A spring-action mechanism separates the handles between working strokes. Orthodontic Pliers Tweed 13cm in this flat-jaw configuration are selected specifically when loop closure requires broad wire contact, not point-contact forming. The instrument is fully autoclavable at 134°C.

Orthodontists use the Tweed Loop Plier 13cm during Tweed-Merrifield edgewise treatment, closing loop positions in 0.018″ × 0.025″ and 0.019″ × 0.025″ rectangular archwires, placing tip-back bends in the posterior segments, and adjusting arch width in rectangular wire during finishing stages. Tweed Wire Bending Pliers, 13cm | Orthodontic Pliers of this flat-jaw type are the standard choice when wire grip stability across the full beak face determines bend accuracy.

Leader Surgical manufactures this instrument to strict jaw-face parallelism tolerances, a build requirement where any angular deviation between the two flat beaks introduces unwanted torque into the wire during loop closure.

What is the primary purpose of this plier?
The Tweed Loop Plier is an essential orthodontic tool used to form precise loop, specifically omega, bull, and helical loops, in archwires. It is a critical instrument for procedures requiring space closure, tooth alignment, and fine-tuning forces on specific teeth.
