Orthodontic Gauges

Types of orthodontic gauges

Boley gauges

A dental caliper with a vernier scale for tooth and space measurement: the Boley gauge, ortho style, the modified Boley gauge, and the modified high precision gauge — a Boley with narrow, precise tips that measures up to 8 cm, for interproximal and posterior measurement.

Bracket height gauges

Bracket gauges come star-type and straight-rod: the Boone bracket positioning gauge is the star type, with smaller steps for incisors, canines and premolars and larger ones for molars; the bracket height gauge and the adjustable bracket height gauge check the bracket-to-incisal-edge distance before the adhesive is cured.

How to choose an orthodontic measuring gauge

• Measuring or positioning. Tooth widths, arch length, overjet and models → a Boley gauge; bracket placement → a bracket gauge.
• Reach. The narrow tips of the high-precision gauge reach between crowded teeth and into the posterior arch.
• Bracket heights. Common fixed heights are 3.5, 4.0, 4.5 and 5.0 mm; star gauges carry several heights on one instrument, and swivel-head gauges articulate to reach anterior and posterior teeth.

What are Boley gauges and bracket gauges used for?

Space analysis and tooth-size calculations, measuring tooth widths, inner and outer arch dimensions and overjet; checking brackets, bands, wires, appliances and study models at the chair or in the laboratory; and setting and checking bracket height in direct bonding, including on the smaller crowns of younger patients.
