LM-SharpJack™ SD

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 Prophy & 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!

Opposites attract. This holds true with high-quality, periodontal instruments. Optimally they are razor sharp, extremely hard, yet smooth and light. A new micro membrane coating made using modern Physical Vapor Deposition (PVD) technology enables LM to create LM Sharp Diamond™ instruments with the optimum combination of these features. LM Sharp Diamonds™ are completely sharpen free, tough but refined, offering unique benefits for you and your patient.

Choosing the handle

Choosing the most ergonomic hand instrument can make a big difference in terms of discomforts and disorders when performing dental work. It is by no means insignificant what the diameter of the hand instrument’s handle is or what the material of the grip surface is. When holding the instruments for approximately 2,000 hours each year, the design, weight and feel of the instrument are crucial for the dental practitioner in terms of his/her performance and productivity.

LM instruments are available with a selection of different handles. All exceptionally ergonomic due to the elastic silicone coating and optimized contouring. The clinician’s hand fit and indication both play a role in selecting an ideal handle type. Interchanging different handles, may place the user’s hand under even less strain.

New colors, naming and coding

To facilitate color coding and brighten up working practices LM-ErgoSense®, LM-ErgoMax™ and LM-ErgoNorm™ instruments come now in new refreshing colors. The name and the code number on the handle ease the identification of the instrument during clinical procedures and maintenance.
