Temperatures during drilling for the placement of implants using the osseointegration technique

Generated heat at implant site during gradual and single-drill protocols among Indian patients

“…This was contradictory to the findings of Matthews and Hirsch [ 13 ] in 1972 where authors reported that surface temperature assessed decreases proportionally with increased distance between the surface and drilling site. In the present study, the drilling in the artificial bone blocks was done at a speed of 1500 rpm which was consistent with the pioneer study of 1986 by Eriksson and Adell [ 14 ] However, other studies of Tehemar [ 15 ] in 1999 reported that lesser heat is generated by drilling at a lower speed. However, drill speed cannot be considered as an individual predictor for heat generation during drilling.…”

Temperature Changes (ΔT) in Correlation with Number of Implant Osteotomy Preparations in Human Cadaver Tibiae, Comparing Osseodensification (OD) Burs in Clockwise (CW) versus Counterclockwise (CCW) Mode

“…One thousand (1000) RPM had the least effect on ∆T in both modes, confirming our previous findings [26]. The critical temperature point, which can compromise the bone around an implant, was described as being >47 • C for one minute, since it significantly reduced the bone formation around implants [31,32]. To measure the temperature, a K-type thermocouple measuring unit was utilized in the present study due to its higher accuracy in a liquid medium compared to infrared thermography [33][34][35].…”

Influence of multiple use of Timedur®‐titanium cannon drills: thermal response and scanning electron microscopic findings

“…The mean temperature of all drillings was 31.55aeC and the highest was 36.3aeC. These results are comparable to other investigations using new drills (Eriksson & Adell 1986;d'Hoedt et al 1987). In the present investigation the maximum temperature increase due to re-usage was only 0.13 K per generation (i.e.…”

“…In order to determine a hypothetical threshold temperature one would need to know more about the time dependence of heat-traumata and the actual temperature of bone close to the cutting edge. Using a thermocouple 0.5 mm from the drilling site, Eriksson & Adell (1986) found in their human in vivo experiment maximum drill temperatures comparable to those found in the present investigation. These authors used the implant technique described by Brånemark and co-workers, which is known to provide a sufficient osseointegration (Malevez et al 1996).…”
