Materials and Methods: Thermocouple technology was used to measure temperature level generated while drilling during osteotomy procedure for implant place in a bovine femoral cortical bone model. Drilling was accomplished by using milling machine .External irrigation at a constant ratio was used. The temperature of this irrigating solution was stabilized at 5°c and 25°C and The drilling depth was 8 mm and diameter of 2mm. Heat measurements were recorded after the final drilling for each irrigating solution in addition to time necessary to drop to base line level was recorded . Results: Results showed that cooled solution at 5 °C can decrease the temperature to a significant level better than solution at room temperature. In addition time needed to return to base line temperature levels is less than when using solution at room temperature. Conclusions: It can be concluded that the using cold irrigating solution can decrease the heat generated at implant site preparation consequently leading to decrease damage in the bone.

Effect of surgical drill guide and irrigans temperature on thermal bone changes during drilling implant sites - thermographic analysis on bovine ribs

“…It eliminates heated bone chips from the osteotomy and reduces friction during drilling, thus contributing to decreased generation of the frictional heat 13 . Saline at room temperature can provide sufficient cooling during conventional drilling, although in dense cortical bone or at high rotational speed deleterious bone temperatures might be generated 14 . Cooled saline is proved to be more effective when drilling without the surgical guide 15 .…”

Appraising efficiency of OpSite as coolant in drilling of bone

“…They indicated that while there are several parameters that increase bone temperature during drilling, cooling (as external irrigation in their case) can be the only and the most important factor in limiting this increase in bone temperature and must be used for bone drilling. On the other hand, Shakouri et al [3], Sener et al [17], Al-Dabag and Sultan [23], and Sindel et al [24] determined the efficiency of external cooling with normal saline as coolant. They also indicated similar positive influence in limiting the maximum temperature elevation.…”
