Abstract
Purpose : The objective of this research was to investigate an optimization of drill design factors for implant stability and
efficacy through comparative evaluation by the cutting time, heat generation and initial stability.
Materials and Methods : Three design factors were considered for the purpose of drill design optimization; the number of
flute(2 flute, 3 flute), helix angle(15°, 25°) and drill tip shape(straight, 2-phase). Design factors were selected through comparative evaluation by temperature change, cutting time and ISQ value.
Results : Heat generation and cutting time are influenced by all design factors(p<0.05). Drill tip shape was the only factors
which influenced to the largest initial stability(p<0.05).
Conclusion : Drills with 2 flutes, 2-phase formed drill tip, and 25 degrees of helix angle exhibit a better performance than other design.
