Purpose. The purpose of this study was to evaluate the performance efficiency of two different drill combinations according to the heat generated and drilling time.

Materials and methods. In this study, cow ribs were used as research materials. To test the specimen, cow bones were rid of fascia and muscles, and a temperature sensor was mounted around the drilling area. The experimental group was divided into a group using a guide drill and a group using a Lindmann drill according to the drill used before the initial drilling. The drilling sequence of the guide drilling group is as follows; guide drill (©ª 2.25), initial drill (©ª 2.25), twist drill (©ª 2.80), and twist drill (©ª 3.20). The drilling sequence of the Lindmann drilling group is as follows; Lindmann drill (©ª 2.10), initial drill (©ª 2.25), twist drill (©ª 2.80), and twist drill (©ª 3.20). The temperature was measured after drilling. For statistical analysis, the difference between the groups was analyzed using the Mann-Whitney U test and the Friedman test was used (¥á = .05).

Results. The average performance efficiency for each specimen of guide drilling group ranged from 0.3861 to 1.1385 mm3/s and that of Lindmann drilling group ranged from 0.1700 to 0.4199 mm3/s. The two drill combinations contained a guide drill and Lindmann drill as their first drills. The combination using the guide drill demonstrated excellent performance efficiency when calculated using the drilling time (P < .001).

Conclusion. Since the guide drill group showed better performance efficiency than the Lindmann drill group, the use of the guide drill was more suitable for the primary drilling process.
