Prima Dental Classic Inverted Cone Carbide Burs are expertly designed for cutting precision undercuts during restorative cavity preparations. These burs feature a sharp-edged, inverted cone shape that facilitates the formation of mechanical retention at the junction of the pulpal floor and lateral walls, particularly in Class I, II, and IV cavities. Their shape is perfect for creating occlusal locks and cervical undercuts, ensuring long-term stability of restorative materials. Manufactured from premium-quality carbide, these burs provide consistent, vibration-free performance, enhanced durability, and optimal cutting efficiency. Suitable for use with high-speed FG handpieces, they support clinical accuracy in both conservative and complex restorative procedures.
