Journal of Biomechanical Science and Engineering, 2018 Dental plaque on the surfaces of implants causes peri-implantitis and periodontitis. Although the plaque needs to be removed from the surfaces, it is difficult to clean it from the screw section of an implant, as this is roughened to improve ...

Enhancing the Aggressive Strength of a Cavitating Jet and Its Practical Application
Journal of Fluid Science and Technology, 2011 A cavitating jet is a useful tool for the practical application of cavitation. Cavitation impact arises when bubbles collapse and can be utilized to modify the surfaces of materials as an alternative to shot peening.

Visualization of cavitating micro jets [PDF]
EPJ Web of Conferences, 2012 The paper deals with one experimental set up integrated for research of the cavitating micro flows, which is incipient behind the micro channel or micro discharge nozzle outlet port. Experimental system is integrated from three major systems: hydraulic circuit with installed discharge nozzle (or micro channel), subsystem for data acquisition and data ...

Destruction of Plankton using Cavitating Jet
Journal of Fluid Science and Technology, 2008 This paper presents the experimental result of the destruction of plankton using a cavitating jet generated by a two-dimensional nozzle. The destruction rate of plankton increased with the jet velocity and it reached almost 100% when the nozzle velocity ...

Vizualization of the cavitating jet using flashlamp for illumination
EPJ Web of Conferences, 2012 The contribution deals with the ways of the illumination of the cavitating jet for the purposes of the visualization. The cavitation is induced by the fluid flow through the orifice with the diameter of 0,3mm.

Evaluation of the efficiency of cleaning dental plaque on titanium using a cavitating jet
Journal of Biomechanical Science and Engineering, 2014 Dental plaque, which adheres to the surfaces of dental implants and remains in the gingival crevices, can cause peri-implantitis, which is similar to periodontal disease; consequently, cleaning the dental plaque from these surfaces is very important.
