- Universal sickle scaler used by dental professionals for removing calculus and stains from all tooth surfaces, with a design that is particularly effective for posterior teeth
 
- A variation of the standard 204S sickle scaler, with its tip design featuring distinct enhancements for posterior scaling
 
- The "SD" in the model name indicates that the tips are specifically for accessing and scaling the distal surfaces of posterior teeth
 
Applications:
- Universal scaling:
 
- This instrument can be used for the effective removal of supra- and subgingival calculus deposits from all tooth surfaces
 
- Root planing:
 
- The fine, sharp tips are suitable for smoothing the tooth root surface, a procedure known as root planing
 
- Posterior scaling:
 
- The tip design is optimized for scaling the posterior teeth and navigating tight interproximal spaces in that area
 
- Heavy calculus removal:
 
- The blade design is effective for removing moderate to heavy calculus deposits
 
Features:
- 
204SD Tip design:
 - Double-ended:
 
- Like the standard 204S design, the instrument has two working ends that are mirror images of each other
 
- This allows clinicians to use the same instrument to access both the distal-buccal and distal-lingual surfaces of posterior teeth
 
- Site-specific for distal surfaces:
 
- The key difference from a universal 204S scaler is the blade angulation
 
- The H204SD's specific design is optimized for scaling the distal surfaces of posterior teeth, allowing for more precise adaptation and efficient calculus removal in these hard-to-reach areas
 
- Short, angled shank:
 
- Features a shorter, more angled shank than a standard straight scaler
 
- This makes it particularly effective for reaching and adapting to the complex contours of posterior teeth and navigating tight interproximal spaces
 
- Sickle blade:
 
- The blade has a triangular cross-section with two cutting edges that converge to a pointed tip
 
- This design is highly effective for removing moderate to heavy calculus deposits
 
- Versatility:
 
- While optimized for posterior teeth, the design is also suitable for use on anterior teeth, making it a versatile tool for universal scaling
 
- SmartSharp technology:
 
- The tips are made from heat-treated, cryo-hardened 440A stainless steel
 
- This technology ensures the tips maintain a sharp edge and precise angle for greater efficiency and less repetitive motion for the user
 
- Autoclavable:
 
- The durable polymer handle is designed to withstand multiple autoclaving cycles, ensuring longevity and proper infection control
 
- Designed for control:
 
- The handle and tip design allow the user to easily maintain control during instrumentation with less pressure required
