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.
