| Abstract | The main purpose of this study was to develop a temperature recording device (termocouple) combined to a computer assisted control system utilized to monitor in vitro the heat generated by bone instrumentation associated to osseointegrated implants insertion. Two types of cooling systems were evaluated, i.e., an internal cooling system and an external cooling system, routinely utilized in implant therapy. The data was collected from the analysis of twenty specimens of bovine bone submitted to different drilling conditions and different positions of the heat recording device (termocouple). Ten specimens were instrumented with 3i drills {Twist Drill 0 2,3mm, Tri-Spade Twist 0 3,0mm and a Pilot Drill 0 2x3mm) and were irrigated externally. The remaing specimens were instrumented by the same sequence of drills but the cooling system of choice was the internal irrigation. Data collected from the experimental procedure were submitted to statistical analysis by the ANOVA2 test and the correlations refined by means of the Tukey (HSD). When a 2,3mm diameter drill was used, the greater changes in temperature where observed between the initial and final time of drilling (average 0,470°C). When comparing the pilot drill and the 3,0mm drill, it was displayed that results were statiscally equivalent. There were no evidence of superiority between two types of instrumentation investigated. On the other hand, when different drills and cooling systems were tested it was shown that the 2,3mm drill produced the greater differences of heat generation between the initial and final drilling times among of the other types os situations tested. It was concluded based in the data collected and submitted to statiscal analysis that the internal irrigation generated less heat than external irrigation. |
