Trephine Bur [AR]

Trephine Bur
• Minimizes the drilling steps needed, especially for wider fixtures.
• Helpful for collecting autogenous bone.
• Useful for removing failed and fractured fixtures.
• Depth markings are 7, 8.5, 10, 11.5, 13mm, same depths as fixtures. (No Y dimension so markings are actual length).
• Markings on the drill shaft represent the inside / outside diameter of Trephine Burs.
