shown throughout the figures , the present invention is generally directed towards a variable speed tooth polishing system , designed specifically to provide users with a practical and efficient means for practicing dental hygiene in a compact , flexible structure that takes into consideration dental aesthetics , gum maintenance , and minimization of contact with potentially infectious substances . referring now to fig1 and 3 , a prophy angle 105 of a variable speed tooth polishing system 100 is shown before it has been inserted into the mouth 400 , past the lips 410 in order to make contact with the gums 420 and teeth 430 . the prophy angle 105 includes are a first polisher 130 , a first polisher gear 132 , a first drive gear 133 , a second polisher 140 , a second polisher gear 142 , a second drive gear 143 , and a splatter guard 160 . referring briefly to fig2 , the prior art prophy angle 500 includes a polisher head 510 , which contains within its structure a polisher motor 520 . the prophy angle 105 may be secured to a polisher hand grip 200 by threading at least one set screw 214 through the prophy angle connector housing 175 into a hand grip connector housing 215 . these screws 214 will “ preferably ” be made of a non - corrosive material , such as plastic . referring now to fig4 , the variable speed tooth polishing system 100 is shown with the prophy angle 105 separated from a polisher hand grip 200 . the prophy angle 105 includes a prophy angle connector housing 175 and the polisher hand grip 200 includes a hand grip connector housing 215 . the prophy angle 105 is connected to the hand grip connector housing 215 by screwing the hand grip connector housing 215 into the prophy angle connector housing 175 . the prophy angle shaft 180 includes a drive slot 195 , which is sized to receive a drive tongue 197 extending from an end of a hand grip connector shaft 210 . the hand grip connector shaft 210 extends from a motor 260 . the first and second drive gears are attached to the prophy angle shaft 180 with set screws 182 or the like . it will be appreciated by those skilled in the art that these structural elements of the present invention may be formed out of natural and synthetic materials , such as plastic , rubber , and combinations thereof , or any of a wide variety of other known materials without departing from the present invention . the figures illustrate the use of threads to connect the prophy angle 105 to the polisher hand grip 200 , but may include any suitable removable assembly method , such as any type of fastener . also illustrated in the figures is a more detailed view of the prophy angle 105 , showing the first polisher 130 inserted into a first polisher housing 110 and a second polisher 140 inserted into the second polisher housing 120 . both the first polisher 130 and the second polisher 140 include a plurality of polisher slots 150 to enable more stable and thorough contact with the teeth 430 and gums 420 . the first and second polishers are preferably fabricated from a flexible material . a splatter guard 160 surrounds the first polisher 130 and the second polisher 140 . a plurality of splatter slots 170 are formed around a perimeter of the splatter guard 160 . the splatter guard 160 is preferably fabricated from a flexible material . it is preferable that the plurality of splatter slots 170 are 5 mm to 7 mm long , but could be any suitable length . the plurality of polisher slots 150 are preferably no more than 3 mm in length . the polisher hand grip 200 includes a hand grip body 230 , a power button 240 , the motor 260 , a hand grip top portion 270 and a handgrip bottom portion 280 . the hand grip top portion 270 terminates a top of the hand grip body 230 and the handgrip bottom portion 280 terminates a bottom of the hand grip body 230 . the motor 260 is retained in the hand grip body 230 . the power button 240 controls the flow of electrical power to the motor 260 . when the motor 260 is activated by the power button 240 , the hand grip connector shaft 210 revolves , which turns the prophy angle shaft 180 . rotation of the prophy angle shaft 180 causes the first and second drive gears to rotate the first and second polisher gears , respectively . spinning of the first and second polishers polishes the teeth 430 and massages the gums 420 . the polisher hand grip 200 also contains the hand grip speed control 600 , which regulates the rotational speed . referring now to fig5 , a second embodiment of a variable speed tooth polishing system 102 is shown with the second polisher 140 replaced by a polisher brush 145 . it will be appreciated by those skilled in the art that the prophy angle 105 ′ of the variable speed tooth polishing system 102 can be attached to other polisher hand grips , and that the first polisher 130 and the second polisher 140 can be removed and either act alone in order to access hard to reach teeth , or be replaced with other variations besides the polisher brush 145 , without deviating from the present invention . another alternative embodiment would entail the first polisher 130 and the second polisher 140 having a plurality of bristles , like those of a toothbrush , or a wide variety of other polishing means without departing from the present invention . fig6 illustrates a control unit 300 of the variable speed tooth polishing system 100 , 102 . the control unit 300 determines the rotational speed of the first polisher 130 and second polisher 140 by movement of an indicator switch 340 to either the first setting indicator 310 ( low speed ), the second setting indicator 320 ( medium speed ), or the third setting indicator 330 ( high speed ). it is attached to the polisher hand grip 200 via a wire 350 . fig7 illustrates a third embodiment of a variable speed tooth polishing system 104 with a single polisher 130 . the variable speed tooth polishing system 104 includes a polisher hand grip 250 and a prophy angle 107 . a hand grip connector housing 217 extends from the polisher hand grip 250 . the prophy angle 107 includes a prophy angle connector housing 177 and a splatter guard 162 . the prophy angle connector housing 177 is preferably screwed to the hand grip connector housing 217 , but other attachment methods may also be used . a polisher housing 112 is retained in the splatter guard 162 . a plurality of splatter slots 172 are formed in a front of the splatter guard 162 . the polisher is retained in the polisher housing 112 . fig8 - 10 illustrate a method of attaching a polisher 130 , 140 to a polisher gear 132 , 142 , respectively . an undercut projection 147 extends from the polisher gear 132 , 142 . a projection cavity 149 is formed in a rear of the polisher 130 , 140 . the projection cavity 149 is sized to receive insertion of the undercut projection 147 . after insertion of the undercut projection 147 , the polisher 130 , 140 is turned 45 degrees relative to the polisher gear 132 , 142 to retain thereof relative to each other . however , other methods of removably attaching the polisher 130 , 140 to the polisher gear 132 , 142 may also be used . since many modifications , variations , and changes in detail can be made to the described preferred embodiments of the invention , it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense .
a variable speed tooth polishing system including a tooth polisher with multiple polishing head capability , in order to provide therapeutic treatment to gums and guard against undesired exposure to potentially hazardous fluids present during routine dental cleansing and polishing , such as polishing paste , tooth paste , blood , and salivary excretions .
