Definitions
- the present invention relates to a method and a device for cleaning and maintaining the polishing apparatus used in the field of dentistry for cleaning dental surfaces by spraying thereon with a polishing powder.
- Numerous air polishers are thus known, which mostly use pneumatic means capable of projecting onto the dental surfaces a flow formed of fine particles of baking soda surrounded by a flow of annular water. It has been found that all of the devices of this type have the recurrent drawback of seeing all of their conduits gradually clog over time under the effect of the formation of agglomerates made up of the mixture of the powder with the humidity of the propellant air.
- agglomerates form first of all in the recessed areas of the ejection nozzle and the supply pipes of the polisher, then end up, over time, ensuring an almost total clogging of the nozzle as well as the pipes of powder supply thereof. Unclogging the main pipe of the nozzle carrying the abrasive powder is a particularly delicate operation to perform because of its very small diameter (of the order of 0.6 mm). To do this, it has been proposed to use, as a swab, a very fine metallic wire which is introduced through this conduit and which is animated back and forth to inside of it.
- the wire in particular because of its small diameter, lacks rigidity and tends to slip away from the agglomerates, so that it cannot ensure effectively the unblocking of conduits. It has also been found, in the end pieces thus treated, that the back and forth movements of the metal wire had the effect of creating in the areas concerned micro-grooves thus forming, for the future, attachment areas favoring the formation new agglomerates.
- the present invention aims to provide a means for cleaning, both preventively and curatively, the various conduits used to convey, in the polishers the polishing powder.
- the present invention thus relates to a method for maintaining and cleaning the conduits of a dental polisher of the type capable of spraying under pressure a polishing powder on a dental surface, characterized in that it comprises an operational phase consisting of injecting under pressure into at least some of the circulation conduits of said powder a solution in which this powder is soluble.
- the solution can be stored in a container kept under pressure by a propellant gas.
- the powder may consist of sodium bicarbonate and the liquid may then consist of a solution of citric acid, in particular a solution in water, the concentration of which will be approximately 4% by weight.
- the present invention also relates to a device for maintaining and cleaning the conduits of a dental polisher conveying a powder for polishing dental surfaces, characterized in that it comprises: - means for pressurizing a liquid behaving with respect to said powder as a solvent, - means capable of channeling this liquid towards the pipes of the polisher.
- the pressurizing means may consist of a container of the "aerosol can" type containing said liquid and a propellant gas. This container may be provided with a nozzle capable of fitting in a sealed manner in a cavity in communication with said duct of the polisher.
- the end of the end piece will be provided with an annular groove receiving an O-ring seal.
- the powder will consist of sodium bicarbonate and the solvent liquid will comprise citric acid, preferably a solution in water thereof.
- the concentration of citric acid in water may be of the order of 4% by weight.
- the cleaning means according to the invention have the advantage of not using mechanical systems so that they respect the integrity of the various conduits conveying the polishing powder.
- FIG. 3 is a view of the rear part of the air polisher shown in Figure 2.
- Figure 4 is a partial view in axial section of the duct cleaning means applied to the air polisher shown in Figures 2 and 3.
- Figure 5 is a partial view in axial section on an enlarged scale of the connection between the cleaning means and the rear part of the air polisher.
- Figure 6 is a partial axial sectional view of an alternative embodiment of the present invention.
- FIG. 1 shows schematically a dental handpiece 1 of the air polisher type.
- the rear part 1a of this air polisher is provided with two supply conduits 2a and 2b which are respectively connected by flexible conduits 3a and 3b, on the one hand to a container 5 containing a pulverulent polishing material 7 constituted, in the case present, sodium bicarbonate and secondly, through a pipe 3b to a pressurized water supply.
- agglomerates of pulverulent material are deposited, on the one hand, in the internal duct 2a of the air polisher and on the other hand in the pipe d 'feed 3a thereof.
- a solution of citric acid was produced in water at a concentration of at least 4% by weight of citric acid and this solution was introduced into a container 9 of the "aerosol can" type.
- This container which is pressurized internally by means of a gas, such as for example nitrogen, comprises a head 11 provided, at its base, with a conduit 13 immersed in the solution 8 and at its external part a nozzle 15 whose diameter is slightly smaller than that of the duct 2a of the air polisher and its end part is provided with an O-ring seal 17.
- the head 11 is provided with closure means 19 such that when a pressure P is exerted on it, the closure means are concealed, allowing the projection through the central channel 18 of the nozzle 15 the solution 8 contained in the container 9
- the user can thus periodically carry out preventive cleaning of the pipe 2a of his polisher or unclogging this pipe when the agglomerates are such that they disturb the normal flow of the pulverulent polishing material.
- the agglomerates can also form in the flexible pipe 3a connecting the container 5 to the air polisher 1 and the user may also, to clean the latter, call on the container 9.
- an adapter end piece 20 may be provided, the front part of which will have a diameter suitable for its watertight positioning in the flexible pipe 3a and a rear part hollowed out with a recess 21 capable of receiving the nozzle 15 of the container 9. It could well be heard call according to the invention to any other means to propel under pressure the cleaning liquid both in the flexible pipe 3a and in the pipe 2a of the polisher, and in particular to manual type spraying means.
