LM-DURAGRADEMAX - Stainless Steel Perio

Effective essentials to comfortably and safely access the whole mouth while maximizing procedural efficiency. 

With LM’s winning combination of superior stainless steel tips and the industry's most highly-rated ergonomic handles, expect the best. Cleaning appointments have never been more easy or pleasant for patients and clinicians alike.

Decision Tree Kits are designed by Kathleen Bokrossy, RDH, president of RDHU. These kits offer LM's most efficiently effective options based on identified stages of periodontal health, for safe whole-mouth calculus removal while enabling the highest standards of ergonomic health.


  • Furcator K/S: DuraGradeMax Stainless Steel. Delicate, angled excavator designed for cleaning of the furcation roof and inner surfaces, particularly concavations and grooves in them. Suitable also for the cleaning of narrow approximal concavities and grooves in incisors and premolars.
  • Gracey 15/16: DuraGradeMax Stainless Steel. Area-specific finishing instrument designed for all types of calculus removal and safe, deep periodontal cleaning of molar mesial surfaces.
  • Gracey 17/18: DuraGradeMax Stainless Steel. Area-specific finishing instrument designed for all types of calculus removal and safe, deep periodontal cleaning of molar distal surfaces.


  • DuraGradeMax Supersteel enables effective calculus removal with less frequent maintenance sharpening
  • Highest-rated ergonomic handle minimizes hand fatigue and potential musculoskeletal disorders
  • Full control and improved tactile sensitivity
  • Savings of time & money
  • Improved productivity & clinical results


Resulting from intense material research, advanced thermomechanical heat treatments, controlled gas atmosphere and cryogenic processing, LM’s DuraGradeMax supersteel alloy represents the ultimate in the field of metallurgy. LM’s proprietary alloy produces the sharpest, hardest, and longest-wearing conventional tips on the market. As a result, LM’s exceptionally durable stainless steel instruments stay sharp longer than other leading uncoated stainless steel instruments before requiring maintenance sharpening. 


Ergonomics and innovation have been the guiding principles of design at LM since the 1980's. The ErgoSense handle is a culmination of intense research and product development in close cooperation with dental clinicians and professionals. Feel the difference in your grip both while working and at the end of your day. 

Lightweight and thicker contoured, ErgoSense handles are ergonomically designed to offer the most comfortable grip and exceptional control even in wet environments. 

To ensure optimal rigidity and tactile feedback, LM’s proprietary metal core runs through from tip to tip. The durable elasticity of medical-grade silicone with colour-coding for easy "at-a-glance" identification, has been tested to remain unchanged through 2,000 autoclave cycles.


All LM products are designed and manufactured in state-of-the-art facilities in Finland. Using the most advanced technology and unique high quality materials, LM products are made in accordance with exacting European regulatory standards and guidelines.
