Design and Cutting-Edge Geometry

Both the 1SX and 1SXM are round carbide burs designed for dental surgery applications. The special cutting-edge geometry of the 1SX Cavity Preparation Bur actively reduces vibrations during use, enabling a patient-friendly excavation process that minimizes discomfort. These burs are easily identified by a distinctive green ring on the shank and a gold-plated neck, making them straightforward to distinguish in a clinical setting.

The 1SXM Variant

The 1SXM features an extremely slender neck compared to the standard 1SX, providing a clearer view of the working area. This enhanced visibility is essential for minimally invasive procedures where precision and control are paramount. The 1SXM is listed in its own 1SXM Excavation Bur Collection; this collection carries the standard 1SX in right-angle (RA) and long right-angle (RA-L) shanks.

Clinical Use

The 1SX is a round carbide bur for minimally invasive cavity preparation and excavation of carious dentin in the slow-speed contra-angle handpiece; the RA-L versions add shank length for deeper access. Busch rotary instruments are manufactured under ISO 13485 certification.

Care and Reconditioning

Busch rotary instruments are reusable: clean, disinfect and sterilize them between patients according to the manufacturer’s instructions, and replace a bur once it dulls or shows damage. Our Dental Bur Reprocessing & Sterilization Guide walks through the workflow for carbide, diamond and steel instruments.
