Abstract: A vibrating piezoelectric atomizer comprising: a piezoelectric tube having a length, a first end defining an opening and a second end, the second end of the piezoelectric transducer tubular body is connected to a horn; the horn is dimensioned to be half wavelength resonator; the horn is folded and located alongside the piezoelectric tube; a metallic disk is connected to the horn near the first end of the piezoelectric tube, whereby by applying an alternating voltage across electrodes of the piezoelectric tube, the piezoelectric tube is excited into a resonant vibration when frequency of excitation equals to half wavelength resonant frequency of the piezoelectric tube's length and vibrates in synchronism and is communicated to the metallic disk to atomize a liquid.

Abstract: A TL/T tip is made by scaling down the dimensions of an L/T tip by the ratio of the TL/T frequency to the L/T frequency so that the TL/T tip can operate by excitement from a transducer at the same frequency that would have produced L/T motion in the L/T tip. A reductive resonator may be included between the transducer and the TL/T tip.

Abstract: Tooth whitening device for whitening teeth using sonochemistry includes a body, and an ultrasonic transducer provided in the body. The ultrasonic transducer is configured for producing ultrasonic waves in the range of 20-100 kHz, and good results have been achieved with ultrasonic waves at a frequency of 40 kHz. There is an ultrasonic horn provided on the body, and the ultrasonic horn is operatively connected with the ultrasonic transducer. A liquid retaining element is provided on the ultrasonic horn, and the liquid retaining element is configured for retaining a liquid tooth whitening composition against a user's teeth. The liquid retaining element may be a sponge or a replaceable pad, such as a foam pad.

Abstract: An ultrasonic tissue dissection system providing combined longitudinal and torsional motion of tips, together with irrigation and aspiration, for improved cutting of resistant biological tissue. The system permits the use of common and inexpensive electro-mechanical transducers for the production of such motion through the use of longitudinal-torsional resonators.

Abstract: An ultrasonic dental scaler insert includes a tool coupled to a connecting body which is mechanically coupled to a transducer. When the insert is placed within an ultrasonic dental scaler device handpiece, the transducer produces ultrasonic vibrations which are transmitted to the tool via the connecting body. In order to reduce the noise generated by the operating scaler insert, the connecting body includes an elastomeric material which surrounds a portion of the connecting body. Additionally, a sleeve is provided which surrounds a portion of the connecting body providing a place to grasp the scaler insert during operation. The sleeve includes a bellows section which provides vibrational damping for the insert. Furthermore, the connecting body includes a vibration dampening bushing at an end adjacent the working tool.
