Advanced Periodontal Scaling with the LMErgoMax 313-314 XSi
The LMErgoMax LM 313-314 XSi (commonly referred to as the LM23 pattern) represents the pinnacle of dental instrument engineering. Designed specifically for the challenging distal surfaces of posterior teeth, this instrument combines a sickle’s strength with a Gracey’s precision. The 313-314 features a shorter blade and a longer lower shank, providing unparalleled access to difficult subgingival and supragingival areas.
The Sharpen-Free (XSi) Advantage
Maintenance of dental instruments is a significant overhead for modern practices. The LM XSi series utilizes a sophisticated PVD (Physical Vapor Deposition) coating that keeps the blade sharp throughout its clinical life. By eliminating the need for stones and honing, you ensure a consistent cutting edge every time, saving both time and instrument replacement costs.
Ergonomic Excellence by LM-Instruments
The ErgoMax handle is the classic choice for dental hygienists and therapists. Its elastic silicone coating and optimized 11.5mm diameter offer a relaxed grip that prevents the “pinch-grip” fatigue common with thinner steel handles. The material is designed to provide a secure, non-slip hold even when gloves are wet.

Maintenance & Sterilization Guide
To preserve the sharpen-free coating and the ergonomic silicone handle:
- Avoid Abrasives: Do not use metal brushes or abrasive cleaning stones on the XSi coated tips.
