If the tooth has been sufficiently exposed but is still resistant to moderate force, tooth sectioning must be considered. The tooth is sectioned into appropriate pieces for easy delivery from the socket. Sectioning of the tooth not only avoids additional bone removal, but it also reduces operating time. Tooth sectioning can be carried out using a bur, which is preferred, or a chisel. In the standard technique, sectioning is carried out using the bur at the neck of the tooth, which facilitates crown removal first, followed by the roots in a single piece. Alternatively, the tooth may be divided horizontally also. Nevertheless, in cases of divergent roots, or where the path of withdrawal is complex, the roots may have to be divided and removed separately.

Sadly, the theft and fraudulent use of brand names and trademarks has a truly ancient history in Japan. Swords are an excellent example.
