Nonsurgical ultrasonic endodontic instruments
Dental Clinics of North America, 2004The advent of nonsurgical ultrasonic tips has opened up a new horizon in endodontic treatment. There are a number of nonsurgical endodontic ultrasonic systems currently available in the market and it is difficult to renew all of them. Based on similarities among different instrument systems, and attempt has been made to classify instruments into broad ...

Instrument for ultrasonic lithotripsy
The Journal of the Acoustical Society of America, 1989An instrument for ultrasonics lithotripsy comprises a probe which is applied to the stone which is to be disintegrated, which may be placed in oscillation by means of a piezo-electric sound transducer which is assembled from ceramic discs. The transducer is energized into oscillation by an electrical generator and the transducer oscillations are ...

Cutting characteristics of ultrasonic surgical instruments
Clinical Oral Implants Research, 2011AbstractObjective: Ultrasonic surgical devices are becoming increasingly popular and work is required to understand the performance of the cutting tips. This experimental study looks to investigate the way in which ultrasonic bone cutting tools oscillate and how this oscillation is modified when contacted against bone surfaces with varying loads.

Ultrasonic endodontics: The wear of instruments with usage
Journal of Endodontics, 1986A series of stainless steel and diamond files were used to chemomechanically prepare canals. The files were examined under the scanning electron microscope when new and after up to 20 min of usage for evidence of wear or failure. Both types of files were of good quality and showed little evidence of wear and virtually no failures at any usage time ...

An instrument for ultrasonic biometry.
Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 1978A simple instrument has been developed for measurement of axial length and anterior chamber depth. It is pocket sized, and the digital output is easy to interpret. The long term accuracy of 0.2 mm is ideal in helping to eliminate errors of lens selection.
