The characteristic of high frequency ultrasonic vibrations of an ultrasonic dental drill plays a crucial role in performance of superior precision bone surgery. This paper proposes an attempt to enhance its vibration performance based on the composite horn consisting of an ultrasonic horn and working tip. Finite element analysis has been carried out to investigate dynamic analysis of different structures of composite horns including vibration modeling and harmonic response analysis. Natural frequency of the ultrasonic horn is calculated within the range of excitation frequency of ultrasonic horns in the vibration modeling, while the combined displacement and mode shape of the composite horn are obtained in the harmonic response analysis. The dynamic analysis confirms that the natural frequency and the resonance frequency of the composite horn can be adjusted by designing the small end length of the ultrasonic horn, and suitable mode shape of the composite horn can be obtained by changing the shank angle of working tip. The research finding provides theoretical principles for designing an ultrasonic dental drill in dental implantology.
