The Jack B. Nimble slim is a slimmer version contra-angled scaler with a continuous curved blade designed for crowded, rotated or lingual-version teeth to better reach interproximal areas. Structured so the increased surface of the cutting edge comes in direct contact with the tooth surface when scaling, it allows practicitioners to apply positive lateral pressure when working in anterior/premolar regions. PDT instruments are ideally weighted, featuring the most ergonomic handle with knurling to the instrument shank to provide increased comfort with less hand fatigue and pinch. PDT's focus on ergonomics greatly reduces the development of musculoskeletal disorders.
