Curette Insert, Gracey 13 M5, ZEPF NANOPAL Coating
The Gracey Curette Insert is a precision periodontal instrument designed for area-specific subgingival scaling and root planing, and this Gracey 13 M5 variant from Helmut Zepf GmbH features an advanced ZEPF NANOPAL Coating for enhanced clinical performance. The NANOPAL surface treatment is engineered to reduce friction during instrumentation, supporting smooth, controlled strokes across root surfaces in posterior regions.
Instrument Design and Application
The Gracey 13 M5 is specifically designed for use on the distal surfaces of premolars and molars, making it an essential component of a comprehensive periodontal instrument set. Its area-specific angulation ensures optimal adaptation to tooth anatomy, allowing clinicians to achieve thorough calculus removal with minimal trauma to surrounding tissues.
ZEPF NANOPAL Coating
The proprietary NANOPAL Coating applied by Helmut Zepf GmbH provides a durable, low-friction surface that may help extend the working life of the instrument tip. This advanced coating technology is intended to maintain edge integrity over repeated sterilization cycles, supporting consistent clinical outcomes across a busy dental practice workflow.

Design Notes
The M5 design: the first shank is about 3 mm longer than standard and the sharpened working end is shortened, with a 0.95 mm thin, flexible and therefore highly tactile first shaft — built for special subgingival curettage in tight, deep pockets (beyond 5 mm) and along narrow root surfaces. Manufacturer literature (PDF).
Nanopal® coating: the black crystalline nano-coating raises surface hardness to 4,500 Vickers — the highly tempered cutting edge stays aggressive and sharp far longer and does not need resharpening after each curettage, while the scratch-resistant black surface is easy to clean and prevents light reflections. Manufacturer literature (PDF).

The Gracey 13 working end is an area-specific curette for the distal surfaces of posterior teeth, used for subgingival scaling and root planing; the M5 version has a longer, thinner first shank and a shortened blade for deep, narrow pockets. The ZEPF NANOPAL coating gives a harder surface that holds its edge longer. When the edge is worn or sharpened down, only this insert is exchanged and the handle is kept.
