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 formed in the proximal section and is adapted to connect with a torque monitoring device. A drill bit is connected to the distal section. The drill bit includes a cutting portion having at least one helical flute formed thereon. 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. A mounting portion is formed in one end and is adapted to connect with a torque monitoring device. A cutting portion is disposed on the other end of the shank and has at least one helical thread formed thereon. A medial, non-cutting portion is disposed between the cutting portion and the mounting portion. The medial portion has a diameter less than a diameter of the cutting portion so as to minimize friction forces.
摘要翻译：麻花钻和骨头龙头各自监测在钻孔或穿线时的扭矩以评估颌骨质量，以及在牙齿植入过程期间或同时敲入骨中时获取骨质量的方法。用于评估骨质量的麻花钻包括具有近侧部分和远侧部分的柄部。安装部分形成在近侧部分中并适于与扭矩监控装置连接。钻头连接到远端部分。钻头包括切削部分，其上形成至少一个螺旋槽。钻尖位于钻头的切削部分的端部，其具有在约45°至约55°之间的螺旋角，其中产生可测量的扭矩，该扭矩可以根据骨材料质量钻出。在敲击过程中评估骨质量的龙头包括具有相对端的柄。安装部分形成在一端并且适于与扭矩监控装置连接。切削部分设置在柄部的另一端上并具有形成在其上的至少一个螺旋螺纹。内侧的非切割部分设置在切割部分和安装部分之间。内侧部分的直径小于切割部分的直径，以使摩擦力最小化。
