LM 315-316SD ES
  • Description
  • LM Sharp Diamond™ coated instruments

LM Sharp Diamond™ instruments are micro membrane coated instruments, which are completely sharpen free. The new coating is composed using modern Physical Vapor Deposition (PVD) technology, making the instruments razor sharp, extremely hard, yet smooth and light.

LM-SharpJack™ scaler features long, thin blades for convenient interproximal access.  The instrument shank is optimally angulated to universally adapt in anterior and posterior regions.  Each tip is dual-edged and can be conveniently used for both mesial and distal, as well as buccal and lingual, surfaces.

  • Sharpen free
  • Universal scaler, supragingival, with long, thin dual-edged blades for easy and efficient interproximal access.
  • Anterior/posterior.

Purple Hygiene & Perio – Healthy gums support a healthy brain

The purple handle color of the new LM-SharpJack™ scaler was carefully chosen to honor dental hygienists and preventive dentistry across the globe, as well as to raise awareness of Alzheimer’s disease. In recognition of the latest researches about the association between poor dental health and Alzheimer’s disease LM wanted to raise awareness of the condition and support this essential cause by donating 1 $ per sold LM-SharpJack™ instrument to Alzheimer’s research at the end of year 2018. The LM-SharpJack™ Alzheimer’s campaign will continue in the U.S. market during 2019.

We want to thank all our customers for joining this good cause!

Sharpen Free LM Sharp Diamond™ Instruments

LM Sharp Diamond™ periodontal instruments have a breakthrough, ultra-hard coating that keeps them razor sharp. Their soft silicone grips set the standard for comfort and tactile response.

Comfort and sensitivity

LM-Dental™ pioneered the use of premium-quality silicone to improve sensitivity and comfort. Our LM-ErgoSense® handles make instruments lighter and more responsive in your hands.

New micro coating

Physical Vapor Deposition (PVD) technology bonds a diamond-like micro-coating to LM Sharp Diamond™ instruments. Our fine surgical steel takes a razor edge and the PVD coating protects that edge, giving you a more effective instrument for longer.

Exceptional hardness and durability

Hardness contributes to the durability of the instrument. LM Sharp Diamond™ reach hardness of over 63 on Rockwell scale.

Wear resistance*

Better instruments, better outcomes

Sharpen free LM Sharp Diamond™ instruments enable you to remove calculus without fracturing it. They’re ideal for all forms of depuration.

Choose the Right Ergonomic Handle to Fit Your Hand

Every year, you hold dental instruments in your hands for about 2,000 hours. The right fit can make your work more efficient and productive. The wrong fit can lead to repetitive-stress problems in your hands and arms.

Details Make the Difference

We make LM-Dental™ instruments with a variety of handle types. Elastic silicone coatings and optimized contours fit your hands and give you the perfect grip. Extensive research ensures that LM-Dental™ instruments are the perfect weight and diameter for easy manipulation.

Bright Colors for Easy Identification

The refreshing colors of LM-ErgoSense®, LM-ErgoMax™ and LM-ErgoNom instruments brighten your practice. Color also helps you identify the instruments you want during procedures and maintenance.

The Right Handle for Every Purpose


Research has shown these larger handles to be ergonomic and efficient, and the excellent grip gives you more control. You can choose LM-ErgoSense® handles with RFID tagging. Tagged instruments are compatible with the LM Dental Tracking System™ for improved patient safety and asset management (see more on dentaltracking.com).


This is the classic ergonomic design, unique to LM-Dental™, that other companies attempt to copy. Excellent tactile sensitivity and relaxed grip make it ideal for all clinical procedures.


For light procedures, thinner LM-ErgoNom handles give you excellent grip and sensitivity.
