Iwanson Spring Caliper for wax

Iwanson Spring Caliper for wax

The Iwanson Spring Caliper for Wax is manufactured from medical-grade stainless steel, featuring a triangular open-frame spring-bow design with two straight arms terminating in fine pointed tips. A spring-tension upper bow maintains consistent arm separation pressure during measurement, while a central flat-head adjustment screw between the arms controls tip spacing with precise incremental tension. The curved measurement arc at the instrument base carries engraved graduation markings spanning 0–10mm, providing direct wax thickness readings without requiring separate measurement instruments.

The spring-bow mechanism of this dental wax thickness measurement caliper maintains constant, controlled tip contact pressure against wax surfaces without requiring manual grip force, eliminating measurement distortion caused by operator finger pressure compressing the soft wax material during thickness assessment. The central adjustment screw allows pre-setting tip spacing to a target thickness before contact. This Iwanson spring caliper for wax instrument is fully autoclavable at 134°C, maintaining spring tension calibration, tip alignment, screw mechanism function, and arc scale legibility through repeated sterilization cycles without spring fatigue or corrosion.

The Iwanson Spring Caliper for Wax is used by prosthodontists and dental laboratory technicians during complete denture fabrication and crown wax-up procedures. Using this wanson caliper instrument, the technician or clinician gently places both pointed tips against opposing wax surfaces, allows the spring mechanism to self-regulate contact pressure, and reads the direct thickness value from the curved arc scale to verify wax occlusal rim thickness, baseplate dimensions, and coping wax uniformity against prescribed fabrication specifications.

Leader Surgical demonstrates thorough prosthodontic workflow knowledge by including specialized instruments like this Iwanson spring caliper within its catalog, a wax-specific measurement tool requiring calibrated spring tension and pointed tip geometry that standard calipers cannot replicate, reflecting a brand that serves dental laboratory and clinical prosthodontic teams with equal depth and specificity.

Why are the tips “blunt” or “rounded” instead of sharp?
The blunt (chamfered) tips are specifically designed for wax and other soft materials so you can take measurements without scratching, marking, or piercing the delicate material.
