DECISION TREE KIT - Stage II-IV (Sharpen-free)

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


This set of 6 instruments is ideal for clients who present with more complex anatomical considerations such as concavities, projections, and furcations.  The extended functional shank combined with a smaller blade length will provide comfortable access into deep, narrow pockets while decreasing the risk of tissue distention and tissue lacerations without compromising tip placement. 

Curion is the ONLY authorized distributor of LM Dental Instruments in Canada. This product is backed by the manufacturer's warranty.

LM-SHARP DIAMOND - Sharpen-Free Perio

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

With LM’s winning combination of advanced SharpDiamond sharpen-free 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.


  • H6/H7 Sickle Scaler: Sharpen-free. Sickle scaler with small contra-angle for the removal of calculus above the gumline on proximal surfaces of incisors and pre-molars.
  • 204S Sickle Scaler: Sharpen-free. Sickle scaler for the removal of supragingival calculus on posterior interproximals.
  • Furcator K/S: DuraGradeMax Supersteel. 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 1/2: Sharpen-free. Area-specific finishing instrument designed for all types of calculus removal and safe, deep periodontal cleaning of incisors and pre-molars.
  • Gracey 15/16: Sharpen-free. Area-specific finishing instrument designed for all types of calculus removal and safe, deep periodontal cleaning of molar mesial surfaces.
  • Gracey 17/18: Sharpen-free. Area-specific finishing instrument designed for all types of calculus removal and safe, deep periodontal cleaning of molar distal surfaces.
  • Servo 5E Cassette: Made of durable, high-quality resin, this cassette is equipped with safety shields to protect instrument tips as well as prevent prick injuries during the cleaning cycle. The patented design of LM-Servo E safety shield lamels guides the washing fluid through the cassette for proper cleaning of the instrument tips. In addition, the structure supports free rotation of the instruments providing complete cleaning and rinsing. The cassette's open and close mechanism is simple and easy to use.


  • 100% sharpen-free means effective calculus removal without the need to sharpen
  • No more worrying about altered blade tips or angles
  • Effortless, worry-free scaling
  • 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


The dark tips of SharpDiamond instruments look different because they are different. A diamond-like micromembrane enhances the already superior wear-resistance of LM's proprietary alloy base to produce completely 100% sharpen-free scalers and curettes. 

In the final phase of precision-honing, LM’s ultra-modern PVD coating process follows the exact geometric planes of the instrument to ensure flawlessly sharp tips and the longest-wearing edges unmatched by anything else in the field.


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

Because SharpDiamond instrument tips maintain factory edges and remain sharp for the duration of its lifespan, in addition to never sharpening, clinicians can stop worrying about all the issues related to sharpening, once and for all.

And with unparalleled wear-resistant edges that effortlessly shave off every last bit of calculus, less force is needed when scaling. The result is easier, more comfortable scaling for both the clinician and patient without compromising clinical results.


At LM, ergonomics and innovation have been the guiding principles of design 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-coded "at-a-glance" identification, has been tested to remain unchanged through 2,000 autoclave cycles.
