摘要:
A twist drill and bone tap each monitor torque while drilling or threading to assess jaw bone quality and a method for accessing bone quality prior to or while tapping into the bone during a dental implantation procedure. The twist drill for assessing bone quality includes a shank having a proximal section and a distal section. A mounting portion is arranged to connect with a torque monitoring device. A drill point is located at an end of the cutting portion of the drill bit having a helix angle of between about 45 to about 55°, wherein a measurable torque is generated that can be assessed as a function of the quality of the bone material being drilled. A tap for assessing bone quality during tapping includes a shank having opposed ends and a mounting portion is formed in one end and connects with a torque monitoring device.
