Bone Bracket Gauge

Bone Bracket Gauge

The Bone Bracket Gauge is a single-piece flat stainless-steel instrument with a four-arm star configuration; four rectangular blade arms radiating outward from a central disc body at equal angular intervals. Each arm corresponds to one bracket height measurement: 3.5mm, 4.0mm, 4.5mm, and 5.0mm, the four values are engraved directly onto the central disc body adjacent to their respective arms, as confirmed in the product image. Each arm terminates in a flat rectangular blade tip with sharp angular edges at both corners, providing a defined contact point at the incisal or occlusal tooth edge during height measurement. The instrument is compatible with both 0.018-inch and 0.022-inch bracket slot systems.

The star geometry gives immediate access to all four height options from one instrument without flipping or selecting a separate tool. The clinician rotates to the required arm, places the blade tip against the incisal edge, and reads the bracket center height directly from the arm’s contact position against the tooth surface. The flat disc body sits between the thumb and index finger during use, the central mass providing stable rotational control. The instrument is fully autoclavable at 134°C and meets FDA and CE standards.

Orthodontists use the Bone Bracket Gauge during direct bonding sessions to set the vertical bracket height on each tooth before adhesive application, measuring from the incisal edge to the bracket slot center on incisors, canines, and premolars. The Bracket positioning gauge star format removes the need for separate single-height gauges across the full anterior-to-posterior measurement range.

Leader Surgical produces this instrument to verified arm-length tolerances at all four measurement positions, meeting the dimensional requirements of the Bone Guages category for consistent bracket height reproducibility across MBT and Roth prescription bonding protocols.

What is the difference between a Boone gauge and a standard bracket gauge?
A Boone gauge typically features a star-shaped design with four arms, each calibrated to a specific height (e.g., 3.5mm, 4.0mm, 4.5mm, and 5.0mm). Many models also include a marking tool, such as a metal tip or lead, to visually mark the tooth surface.
