DRILL AND TAP AND METHOD FOR PREOPERATIVE ASSESSMENT OF BONE QUALITY

摘要

Twist Drill and tap each goal to drilling or threading in order to assess the quality jaw and it will monitor the torque during relates to a method for evaluating bone quality while tapping bone prior to or during tapping dental implant procedures. Twist drill for evaluating the bone comprises a shank having a proximal section and a distal section. The mounting portion is formed in the proximal section and to be connected to the torque monitoring device. The drill bit is coupled to the distal section. The drill bit includes a cutting at least one of the helical flutes are formed. Drill point from about 45 to about 55 is located in the cutting end portion of the drill bit having a helix angle between , measurable torque that can be evaluated as a function of the quality of the drilling which bone material is generated. A tab for assessing bone of tapping comprises a shank having opposed ends. The mounting portion is adapted to connect and torque monitoring unit and forming the one end. It is disposed at the other end of the cutting portion and a shank at least one helical thread form. Non-cutting portion is disposed between the central portion and cutting attachment. Non-cutting central portion has a diameter less than the cutting diameter to minimize friction.
