ABSTRACT
The atraumatic preparation of the implant bed and the presence of healthy bone factors have been considered essential for osseointegration of an implant (Attard and Zarb 2002). Drilling the implant bed not only causes mechanical damage to the bone but also increases the temperature of the bone directly adjacent to the implant surface (Sener, Dergin et al. 2009). It has been demonstrated that if bone is heated to temperature of 47◦C for one minute, bone necrosis, which may impede the osseointegration of an implant, can occur (Eriksson and Albrektsson 1983). Heat generation, during bone
drilling, has been related with the pressure applied by the operator, characteristics of the drill bit, the drilling depth, the type of irrigation, the rotational speed of the drilling time and the density of the bone tissue. Although bone drilling practice has been performed under irrigation, recent studies in the literature propose the use of a clinical protocol without irrigation, allowing better visibility and collecting bone for use as graft after placement of the implant.
