摘要：
Apparatus is provided for use with a dental handpiece, an oral surgical guide, and a bushing disposed in the oral surgical guide. The apparatus includes a drill bit having, a shank and a rigid guide-sleeve. A proximal end of the guide-sleeve couples to the dental handpiece, such that a lumen of the guide-sleeve and a drill bit coupled to the dental handpiece are coaxial along a central longitudinal axis of the drill bit. An inner diameter of the guide-sleeve is 0.03-0.06 mm greater than a diameter of the shank. The distal end of the guide-sleeve is slidably couplable with the bushing, such that upon the guide-sleeve being advanced into the bushing the dental handpiece is forced to align the axis of the drill bit to be coaxial with a central longitudinal axis of the bushing. Other applications are also described.
