Effect of cooling an irrigation solution during preparation of implant site on heat generation using elite system for

Abstract EN

To compare heat generation when using irrigating solution at 5°C and 25°C during preparation of an implant site in bone using the tools of ELIT implant systems.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.
