Surgical Steel Boley Gauge for Precise Dental and Orthodontic Measurement
The Boley Gauge is a specialised sliding caliper used extensively in dentistry and orthodontics. Its fine-tipped jaws allow for precise measurement of tooth dimensions, spaces, and prosthetic components where standard calipers cannot reach.
Fabricated from surgical-grade stainless steel, this gauge offers excellent resistance to corrosion and withstands repeated sterilisation cycles. The smooth sliding action and clearly marked scale ensure consistent, repeatable readings for diagnostic and fabrication tasks.
Primarily used by orthodontists for treatment planning, dental technicians for creating crowns and bridges, and in clinical settings for general diagnostic measurements.
