Introduction
Dental implant is used to replace the natural dental root. The process to fix the dental implant in the maxillary bone needs a pre vious drilling operation. This machining operation involves the increasing of temperature in the drilled region which can reach values higher than 47°C and for this temperature is possible to occur the osseous necros is [I]. The main goal of this work is to impleme nt an optimi zation method to define the optimal drilling parameters that could minimize the drilling temperature. The proposal optimization method is the Taguchi method. This method has been used with success in machining processes optimization of metallic mate rials [2] . However, the Taguchi method is also used in medical applications, namely in dental medicine [3].
Material and methods
For this study were used blocks of Sawbones in composite material (Figurel), a computer, a MGC data acquisition system , type K thermocouples and a CNC machine programmed to drill the blocks.
Figure1: Sawbones block (left), Solidworks drawing with marking holes and block drilling, thermocouples [4). Several tests were performed and it was possible to record the temperature in the material for different depths as can be seen in Figure 2. The material used is a composite which has mechanical properties similar to cortical bone.

To implemented the experimental tests was used the Taguchi orthogonal array LI8 with three parameters. In table 1 is presented the parameters and their levels.

For each combination of parameters and leve ls were measured the temperature with the thermocouples. Using the obtained results was implemented an ANOV A analysis which is represented in table 2.

Conclusions
The Taguchi method proved that can be used as optimization method to determine the best parameters combination to obtain the minimum temperatures in the drilling process. The combination of parameters and levels which provide the minimum average temperature is A 1 83C I. By ANOV A analysis was possible to verify that the irrigation parameter is the most influent in the drilling temperature.
