Dental Crown Caliper Iwanson Caliper

Dental Crown Caliper – Iwanson Caliper

Description

The Dental Crown Caliper (Iwanson Caliper) is a precision measuring instrument widely used in dentistry and dental laboratories for accurate measurement of small distances and thicknesses important in restorative, orthodontic, and prosthodontic procedures. It is commonly employed to measure the thickness of crowns, bridges, wax patterns, inlays, and other restorative components to ensure they fall within ideal specifications before final fabrication or placement. The caliper’s graduated scale from 0 to 10 mm, precision tips, and spring-loaded design allow clinicians to measure with fine accuracy down to tenths of a millimeter — critical when verifying fit, occlusion clearance, and material thickness in dental work.

Constructed from medical-grade stainless steel, the instrument offers corrosion resistance, smooth spring action, and long-term durability suitable for repeated sterilization. Its ergonomic form makes it easy to handle in both clinical and laboratory environments, providing consistent, repeatable readings that support high-quality dental outcomes.

Key Features

• Precision 0–10 mm Scale — Fine gradation allows accurate measurement of crowns, wax patterns, and restorative thickness. 

• Spring-Loaded Caliper Design — Provides controlled, smooth opening and closing for precise measurements.

• Ergonomic Shape — Comfortable to hold and maneuver in lab or chairside settings.

• Stainless Steel Construction — Durable, corrosion-resistant steel for long-term clinical and lab use.

• Fine Tips — Designed for accurate contact with small surfaces and precise gauging of thickness. 

• Autoclavable & Reusable — Suitable for repeated sterilization cycles without losing accuracy.

Applications

• Measuring the thickness of dental crowns and bridges before final placement.

• Assessing wax pattern dimensions in prosthetic fabrication.
