Description

"DEVICE FOR THE STERILIZATION OF DENTAL SCREWS AND/OR
DENTAL PROSTHESES" Technical Field of the Invention
The object of the present invention is a device for the sterilization of dental screws and prostheses. In particular, the present invention is for application to the sterilization of dental screws and prostheses by photactivation of a surface layer of nanoconstructed titanium dioxide or the like. State of the Art
As everyone knows, when a dentist has to apply a dental screw or a prosthesis on a patient, said screw or prosthesis should be subjected to a sterilization treatment to minimize or eliminate infection risks.
In this case, the dentist, after manually taking out the screw or prosthesis from the package or protective envelope, should place the latter under a UV lamp so as to illuminate the screw and/or prosthesis by the ultraviolet radiation.
When the ultraviolet radiation hits the surface layer, it kills the exposed bacteria and, if the surface layer is coated with nanoconstructed titanium dioxide, it activates the photocatalytic, antibacterial properties of the nanoconstructed titanium dioxide itself. The activation of such properties and the time they remain active depend on how the screws or prostheses are irradiated. In other words, the activation and extent of the surface layer' s antibacterial properties are directly affected by the distance of the screw or prosthesis from the lamp, the inclination thereof to the ultraviolet radiation, the irradiation time, the presence or not of shadow regions, the characteristics of the nanoconstructed surface and of the nanoconstructed titanium dioxide, the exposition of said surface to its interaction with the steam present in the environment, or whatever. Disadvantageously, the ultraviolet lamps presently used and related sterilization techniques, do not ensure the activation of the antibacterial properties of the surface layer and, besides, dentists find them not easy and unpractical to use.
The presently used devices are not, in fact, based on nanoconstructed surfaces, so that they operate only a partial sterilization through radiations in the UV-C wavelength range, whereas in the present device, lamps are used the most part of energy of which is in the range of
300 to 400 Tad, that is, in the of UV-A range.
Moreover, the use of known lamps and techniques do not ensure the activation of said properties in uniform degree over the whole inner surface of screws or prostheses, and they do not ensure either that such properties will remain active for a time interval sufficient to implant the screw or prosthesis hygienically.

By way of example, such surface coating layer is made up of titanium dioxide or similar in the form of nanometric particles.
Preferably, both the first 8 and second 9 sources are made up of respective light emission diodes (LEDs) .
Such diodes emit ultraviolet radiation having a wavelength ranging between 300 and 400 ran, with an irradiance preferably below 5 W/m2. However, a higher value would not be detrimental to the correct operation of the invention.

9.
In any case, a bearing plane "P" is defined in the device 1 onto which the dental screw or prosthesis to be sterilized is made to rest.
In the case of the embodiment shown in Figs. 1 and 2, the bearing plane "P" is defined by the support body 10. In other words, the dental screw or prosthesis is made to abut onto the support body 10 between the second sources 9.
In the case of the embodiment shown in Figs. 3 and 4, the bearing plane "P" is defined by the protective shield 11 made of plastic or glass material which is transparent to the UV rays and on which the screw or prosthesis to be sterilized is made to rest.

Advantageously, the embodiment of figure 6 comprises an active fan-cooling system 17 to avoid any overheating of the lighted sources 8, 9 and of the whole device 1. The invention reaches the envisaged objects and obtains major advantages.
In fact, since the dental screws and/or prosthesis is applied between the first and second sources of ultraviolet radiation, it is reached most efficiently by the same radiation, so that the activation of the photocatalytic antibacterial properties of the coating of titanium dioxide applied on the screw and/or prosthesis is ensured. Moreover, the location of the source (s) of ultraviolet radiation allows a uniform illumination of the screw and/or prosthesis by avoiding shadow regions, so that also the activation of the antibacterial properties results uniform on the surface of same screw and/or prosthesis. Again, the fixed distance between the screw and/or prosthesis makes it possible to standardize the sterilization process, thereby obtaining conditions and duration of sterilization as far as possible uniform and constant, also in relation to the duration of the timer- assisted irradiation step.
