Handle systems and methods for endodontic tools

A handle system for supporting a tool defining a tool axis during the performance of dental procedures comprising:

• a handle defining a handle axis and comprising
• a first handle portion defining a first connection portion, and
• a second handle portion defining a second connection portion, where
• the first connection portion engages the second connection portion to detachably attach the first handle portion to the second handle portion;
• a rotation sleeve comprising a first gear portion;
• a head assembly comprising
• a tool mounting system, and
• a second gear portion;
• wherein
• the handle supports
• the rotation sleeve for rotation relative to the handle, and
• the head assembly such that the first gear portion engages the second gear portion;
• and
• with the head assembly supported by the handle,
• the head assembly engages the tool to support the tool such that the tool axis extends at a first angle relative to the handle axis, and
• rotation of the rotation sleeve relative to the handle causes axial rotation of the tool about the tool axis.

A method of supporting a tool defining a tool axis during the performance of dental procedures comprising the steps of:

• providing a handle defining a handle axis;
• providing a rotation sleeve;
• providing a head assembly;
• and
• supporting a first gear portion on the rotation sleeve;
• supporting a second gear set on the head assembly;
• supporting the rotation sleeve on the handle such that the rotation sleeve may rotate relative to the handle;
• supporting the head assembly on the handle such that the first gear portion engages the second gear portion;
• operating the head assembly to engage the tool to support the tool such that the tool axis extends at a first angle relative to the handle axis;
• and
• rotating the rotation sleeve relative to the handle to cause axial rotation of the tool about the tool axis.
