Abstract
A handle system for supporting a tool defining a tool axis during the performance of dental procedures comprises a handle defining a handle axis, a rotation sleeve, a head assembly and a gear set comprising first and second gear portions. The rotation sleeve supports the first gear portion. The head assembly supports the second gear portion. The handle supports the rotation sleeve for rotation relative to the handle. The handle supports the head assembly such that the first gear portion engages the second gear portion. 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.
