Calipers

Orthodontic calipers are the measurement instruments of appliance planning — precision-machined jaws for transferring exact dimensions between study model, appliance, and chart. This collection covers the Helmut Zepf caliper range from the ZEPF Ortho Master line, made in Germany in surgical stainless steel.

The Zürcher Model Caliper

The Zürcher pattern (128 mm) is the classic orthodontic measuring caliper for work on the model: arch length assessment, tooth width measurement for space analysis, and dimensional checks during appliance fabrication. The fine, precisely ground measuring tips register on model anatomy without marring plaster, and the balanced 128 mm frame reads comfortably in the hand through repeated measurements.

Part of the Ortho Master Line

The full ZEPF orthodontic range — pliers, band instruments, ligature instruments, and accessories — is documented in the Orthodontic Instrument Library, with pattern cross-references in the Comparison Chart and care parameters in the Sterilization & Reprocessing Guide.

FAQ

What is an orthodontic caliper used for? Measuring tooth widths, arch dimensions, and appliance components on study models — the foundation of space analysis and appliance planning.

Is this instrument autoclavable? Yes — German surgical stainless steel construction withstands standard sterilization cycles, though model-only instruments are often kept as clean lab tools.
