[The biomechanical characteristics of the instruments for preparing the bone bed for cylindrical implants].
The author has studied the instruments used for osseous bed preparation for a cylindrical implant in respect of their heating the bone, time of boring, and pressure on the instrument. 21 cadaveric mandibles were used in the study. Round and fissure bursa and a drill were compared at rotation velocities of 1000 to 7000 r.p.m. and pressure of 5 and 10 mg Hg; bone temperature was measured at a distance of 0.5 cm from the drilling site. Drilling with round and fissure bursa was found to essentially heat the bone. The optimal instrument as regards the least heating, pressure on the instrument, and the most rapid drilling was found a drill with a rotation speed of 1000 r.p.m.
