Abstract: An extraction device and method for extracting some or all of a tooth from a patient, such as the root of the tooth, are disclosed. One embodiment of the device includes an extraction burr having helical structure with a positive slope transition portion, and in that manner is distinguishable from a common screw. The helical structure may be configured and shaped such that there is little frictional force placed on the burr as it enters into a tooth. Once the burr enters the tooth the configuration and shape of the burr may provide for increased friction between the tooth structure and the burr, thereby causing the burr to grip the tooth structure and maintain the burr as he tooth is extracted. The extraction burr may include a partial-spiral flute or groove formed in a tip thereof.

Abstract: An extraction device for extracting some or all of a tooth from a patient, such as the root of the tooth. One embodiment of the device includes an extraction bit having helical windings without a linear core portion separate from the windings, and in that manner is distinguishable from a common screw. The extraction bit may include a partial-spiral flute or groove formed in a tip thereof. A lockable and releaseable hand piece for attaching to the extraction bit provides leverage to the user for dislodging the tooth root, and is reversible in its attachment position to the extraction bit.
