ROTOSONICS (for post removal )

Rotosonics is a straightforward method to potentially loosen and remove a fully exposed post. The Regular Tip Roto-Pro bur (Ellman International; Hewlett, New York) is a highspeed, friction grip bur whose six faces are joined by six edges and when rotated one revolution, its edges produce six vibrations per revolution. When the instrument is rotated at 200,000 RPM, it produces 1.2 million vibrations per minute, . This instrument provides an inexpensive method to remove certain posts. The bur is kept in intimate contact with the obstruction and is generally carried counterclockwise around the post.
