Lusterdent Diamond Burs (SO-21 and SO-23 Pointed Cylinder Series) are professional rotary instruments designed for precise axial wall reduction, box preparation, and defining internal line angles in fixed prosthodontics. Combining the parallel walls of a cylinder with a pointed apex, these burs allow clinicians to transition smoothly from flat floor preparation to vertical wall reduction in restricted areas.
Key Clinical Applications:
Crown & Bridge Preparations: Ideal for parallel axial reduction while maintaining sharp internal transitional angles for full-coverage restorations.
Inlay & Onlay Box Preparation: Facilitates clean, vertical wall smoothing and precise floor leveling in conservative preparations.
Product Features:
Pointed Cylinder Geometry (SO Series): The combination of a cylindrical body and a pointed tip offers exceptional versatility for both parallel cutting and localized corner detailing.
Uniform Natural Diamond Coating: Ensures high cutting efficiency, reduced vibration, and smooth surface finishes on enamel and dentin.
High-Strength Stainless Steel Shank: Manufactured to strict concentricity tolerances for secure, stable operation in high-speed handpiece chucks.
Fully Autoclavable: Easily sterilized between patient uses to maintain proper clinical hygiene and infection control standards.
