A complete bleaching unit is made up of an electrochemical system, finding its application in particular in the dental and medical fields, allowing, thanks to the creation of an electrophoretic field, a strong, fast penetration and directing the bleaching agents, their removal under the same conditions together with the molecules responsible for coloration and an effective and controlled penetration of the stabilizing agents for the apatite crystal, basic component of the tooth, such as fluorine. Also thanks to its light-based optical system, the invention provides that the activation of the photosensitive bleaching products by decreasing the heat effect while increasing the photonic effect thanks to a selection of wavelength in the range of 400-500 nm and, finally, thanks to an electro-optical unit, the control of the evolution of coloration by objective spectrocolorimetry-based methods. |
