Proposed procedure in which Expandable Micro-motor Bur removes broken root from its socket. A) Broken root in its socket. B) By using micro-motor, Round bur drilled about half way through root canal similar to a conventional bur. Note that spacers are on. C) Spin stops, EMB removed from canal, micro motor detached from EMB, Round bur unscrewed from Bur base, Spacers reduced or totally removed, Round bur placed back into canal, Bur base mounted on micro-motor, by help of a needle holder Round bur and Bur base screwed back. Expanding Round bur carves its periphery making a spherical cavity around itself. This step is run for a very short period. D) Spin stops, Micro-motor detached and EMB remains in place. While expanded in root canal, Split round bur behaves as an efficient extraction aiding anchor. E, F) The firm anchor eases extraction of the broken root with the help of a needle holder.
