Overview

MANI Diamond Burs (CR Series - Cylinder Round Edge) are precision rotary cutting instruments designed for controlled cavity preparation, shoulder-with-bevel margins, and smooth axial wall reduction. Manufactured in Japan using micro-dense diamond bonding technology, CR series burs combine the parallel walls of a cylinder with a rounded edge to prevent sharp internal line angles.
Key Clinical Applications:
Crown & Bridge Preparations: Ideal for creating smooth, rounded internal line angles during shoulder or chamfer preparation, reducing stress concentrations in ceramic restorations.
Cavity & Occlusal Reduction: Excellent for flat floor preparation with smooth peripheral transitions in composite and inlay/onlay restorations.
Product Features:
Rounded Edge Cylindrical Geometry: Eliminates the sharp 90-degree internal angles typical of flat-end cylinders, improving structural integrity of the restored tooth.
Uniform Diamond Sintering: Evenly distributed natural diamond particles ensure high cutting efficiency, reduced vibration, and minimal thermal buildup.
High-Concentricity Shank: Precision-crafted from premium high-grade stainless steel to prevent runout and protect handpiece turbine bearings.
Fully Autoclavable: Withstands repeated high-pressure steam sterilization cycles up to 134°C without degradation.
