Measuring Caliper by Prof. Krekeler for Measuring Implants (comparison measurements only) | Helmut Zepf No. 31.693.10

The Measuring Caliper by Prof. Krekeler — later refined by Dr. Sven Marcus Beschnidt — is a precision dental instrument engineered to facilitate accurate implant positioning and diameter control in a single, compact tool. Manufactured by Helmut Zepf GmbH and made in Germany, this instrument brings together multiple measurement functions to support predictable, high-quality implant outcomes.

Key Features and Design

• The measuring rods have a thickness of exactly 1.5 mm, enabling immediate control of the maximum diameter of the implant to be inserted.
• Scientific examinations confirm that a bone wall thickness of at least 1.5 mm is necessary to prevent bone resorption following implantation.
• To ensure maximum stability, the largest suitable implant diameter should be selected based on the measurement obtained.
• A locating screw at the end of the caliper allows the measured result to be fixed securely, preventing accidental displacement during clinical workflow.

How the Measuring Caliper Works

When the Measuring Caliper is inserted into the interproximal gap and opened until the measuring rods contact the roots of the adjacent teeth, the inner marking IN displays the maximum possible diameter for the future implant. The upper marking OUT simultaneously indicates the determined outside dimension. This dual-reading system provides a fast, reliable reference without the need for additional instruments.

For comparison measurements only. This practice-oriented design offers a significant improvement in precision, speed, and clinical confidence during implant planning procedures.

FAQ

What is the purpose of the 1.5 mm measuring rods on this Measuring Caliper? The 1.5 mm rods allow the clinician to immediately verify that the remaining bone wall meets the minimum thickness required to avoid resorption after implant placement.

Can the caliper reading be locked during use? Yes. The locating screw at the end of the instrument fixes the measured value, enabling the clinician to record and transfer the result without risk of it shifting.

Is this instrument suitable for all implant diameter assessments? This instrument is designed for comparison measurements only and should be used as a clinical reference tool during implant planning, not as a standalone diagnostic device.
