Superior Anterior Scaling with the LMErgoMax 144-145 XSi (H4-H5)
The LMErgoMax LM 144-145 XSi is a specialized combination instrument designed for clinicians who require efficiency and precision. By combining the H4 Chisel and the H5 Sickle Scaler, this tool allows for the rapid removal of interproximal calculus, particularly in the lower anterior segment where calculus bridges often form.
The XSi Sharpen-Free Innovation
Part of the elite LM-Instruments XSi range, this chisel-scaler is treated with a Physical Vapor Deposition (PVD) coating. This technology creates a surface that is harder than standard surgical steel, allowing the instrument to maintain its factory sharpness through hundreds of clinical cycles. For the modern dental practice, this means more consistent clinical outcomes and a complete removal of sharpening protocols from the daily workflow.
ErgoMax: Designed for Clinical Longevity
Repetitive strain is a significant concern for dental hygienists. The ErgoMax handle features a medical-grade silicone coating that is both soft and high-grip. The 11.5mm diameter is scientifically optimized to prevent the “pinch-grip” effect, allowing for a lighter touch and better control during heavy scaling procedures.

Optimal Care Instructions
Maintain the integrity of your LM XSi instruments by following these steps:
- No Manual Sharpening: Do not use sharpening stones; doing so will remove the XSi coating.
- pH Neutral Cleaning: Only use cleaning agents with a pH between 7 and 9.
- Avoid Metal-on-Metal: Use instrument trays to prevent tips from clashing during ultrasonic cleaning or autoclaving.
