ABSTRACT:
A general purpose dental handpiece comprises a shank portion rigidly fixed to a nonarticulatable head portion adapted to removably support a drill burr along a burr axis disposed at an angle of 105.degree..+-.2.degree. with respect to the axis of the shank portion. The angle of orientation of the burr axis is an optimum angle for performing most routine dental procedures in contrast to the right angle orientation of conventional general purpose dental handpieces.
