ABSTRACT:
An ultrasonic toothbrush for use in personal dental hygiene care includes an exchangeable ultrasonic implement which may be rigidly and removably mounted to ultrasonic power means and readily removed therefrom with a relatively small separating force. Provision is made for coupling the toothbrush to the power means and is arranged to transfer the ultrasonic energy from the power means to the ultrasonic implement with the power means remaining substantially free from absorbing ultrasonic energy as the vibratory energy is transmitted therethrough.
