Initial access and crown removal: The C21RX 012 bur is commonly used to make initial access through metal crowns during endodontic treatment.
Secure the bur in a high-speed handpiece and position it on the metal crown surface.
Apply controlled pressure while moving the bur steadily, cutting through the metal to create an access cavity or section the crown.
Follow recommended speed settings to ensure precision without generating excessive heat.
Crown splitting and sectioning: the bur’s robust cutting edges are ideal for splitting crowns into manageable sections for removal.
Gently guide the bur along the crown’s surface to create a groove, facilitating crown separation with minimal force.
After sectioning, use appropriate instruments to remove crown fragments and prepare the underlying tooth structure.
