push bands so as to seat adapt to contour of the teeth
Band Pinchable Plier
Beaks are in triangular passion with inner surfaces had serrated for better control of band material. It has two types curved and straight. Curved (45˚) pinchable plier used for lower band preparation , and straight is used for upper band preparation. Use - for pinching of bands during band preparation
Peak Plier
Beaks - Contour fitting to the side of a tooth is aided by the concave surface or depression at the outer ends of each of the band clamping portion. Use - for preparation of band to tooth.
Double Beak Pliers
Stainless steel Double beak pliers are used for forming bands in the mouth. Types - Anterior and posterior band fabrications. These were important when all teeth were Banded Use - preparation of band to tooth
Nylon Band Seater

Johnson Band Contouring Plier
Beaks - Tapered with a slight bow. One beak is concave and other is convex allowing re-contouring of bands. Use - re-contour band edges that sometimes get bent during band placement.
Anterior Band Removing Pliers
Beak - narrow groove and sharp end One beak is shorter
Oliver Jones Posterior Band Removing Plier
Beaks - Plastic padded tip and sharp removing beak Plastic head rest on the occlusal surface of tooth and the sharp tip below the gingival contour of the band. Use - Remove posterior metal bands with maximum patient comfort.
Bracket Instrument s
Boons Gauge
It is the most frequently used bracket positioning aid. Stainless steel. It accurately measures height of bracket placement from the incisal edge at 3.5, 4, 4.5 and 5mm. Flat surface rests on incisal/occlusal surface of tooth. Simplifies seating the bracket on the teeth with exactly the right distance between bracket slot and incisal edge with pencil lid or metal tips.
Bracket Positioning & Height Gauge
Aluminum or stainless steel Use - This device simplifies the seating of brackets on the teeth with exactly the right distance between the bracket slot and incisal edge. Adjustable for use on both anterior and posterior teeth. Measures height of bracket placement from the incisal edge at 2, 2.5, 3, 3.5, 4, 4.5, 5 and 5.5mm. Works with .022 & .018 bracket system.

Cutter
Hard Wire Cutter
Hard wire cutters have hard metal tips or tungsten carbide tips. These are heavier and larger than the pin and ligature cutters. These are used to cut all wires up to 0.020" round
Manu’s Heavy Wire Cutter’s
Heavy gauge side cutters. They are capable of cutting wires of up to 1.3 mm diameter. Laboratory purpose
Face Bow Bending / Cutting Plier
The face bow bending pliers are ideal for bending and cutting the outer bows of a face bow. These can be used to bend wires up to a diameter of 1.8 mm.
Distal End Cutter
The distal end cutter is capable of cutting arch wires up to 0.56 x 0.70 mm/ .022" x .028 " both intraoral and extra oral Use - Exclusively for cutting the distal end of wire protruding out of the molar tubes It had a ‘safety’ mechanism to hold the cut arch wire so it does not fall into the patients mouth.

Distal End Cutter Angulated
45 ° and 90˚ angled cutting tips For Posterior Areas
Lingual Distal End Cutter
Used to cut distal end in lingual orthodontics
Photo – Hu-Friedy Catalog
Kruz Distal End Cutter
Similar to distal end cutter Difference - Designed with long body so it can reach back into depth of mouth
