Resum
One of the most usual causes of the failure in dental implant osseointegration is the increase of the temperature above 47 °C during the drilling of the bone because it produces irreversible osteonecrosis. The result is weakened contact of implants with bone and possible loss of rigid fixation. Many studies about the design of the drill bit, contact forces, drill speed, drill point angle and feed-rate have been made. However, in all studies a martensitic stainless steel (AISI 440) has been used...
