Dental prosthesis with sealed attachment interface and cleaning fluid access thereto

Abstract

A dental prosthesis has a gum sealing rim that snugly contacts the patient's gum. The cavity formed within the gum sealing rim is accessed by through holes via which a pressurized cleaning fluid may be injected into the cavity. The cleaning fluid swirls around and washes of bacteria and deposits. Through a number of cleaning fluid drains, the cleaning fluid exits again the cavity. An additional drain blocker may be configured such that it blocks the cleaning fluid drains while it is clamped by the patient between the teeth. The resulting pressure build up in the cavity causes the cleaning fluid to squeeze out and clean the sealing interface between the gum sealing rim and the patient's gum.

DETAILED DESCRIPTION

(6) Referring to FIG. 1, a dental prosthesis 100 of the present invention may have a peripheral side 101 and a central side 102. The dental prosthesis 100 may have a number of artificial teeth 103 embedded in an artificial gum 105. Artificial teeth 103 and artificial gum 105 are separated by an artificial gum line 108. At the attachment side of the dental prosthesis 100 that is opposite the teeth 103 are a number of attachment posts 115 as is well known in the art.

(7) The dental prosthesis 100 features at least one cleaning fluid access 118 and at least one but preferably a number of cleaning fluid drains 120, 121, 122. The cleaning fluid drains 120, 121, 122 are preferably on the peripheral side 101 and above the artificial gum line 108. The dental prosthesis 100 features also a gum sealing rim 111 across which are extending the cleaning fluid access 118 and cleaning fluid drains 120, 121, 122 in the preferred form of through holes.

(8) As shown in FIGS. 2, 3, the gum sealing rim 111 forms a gum sealing interface 131 with a patient's attachment gum 200 while the dental prosthesis 100 is attached thereto via the attachment posts 115 as is well known in the art. A cleaning fluid cavity 125 that is within the gum sealing rim 111 is also in between the dental prosthesis 100 and the attachment gum 200 while the dental prosthesis 100 is attached to the patient's attachment gum 200. The cleaning fluid access 118 and cleaning fluid drains 120, 121, 122 become thereby preferably the sole access to peripherally communicate cleaning fluid to and from the cleaning fluid cavity 125 while the dental prosthesis 100 is attached to the attachment gum 200.

(9) As shown in FIG. 4, the dental prosthesis 100 may be part of a dental prosthesis cleaning system 400 that also includes a drain blocker 300. The drain blocker 300 is configured in conjunction with the cleaning fluid drains 120, 121, 122 such that preferably all cleaning fluid drains 120, 121, 122 are blocked while the drain blocker 300 is in operational position. The drain blocker 300 may have a teeth clamp base 303 that is configured in conjunction with a number of the artificial teeth 103 such that the drain blocker 300 is in operational position and blocking the cleaning fluid drains 120, 121, 122 while the teeth clamp base 303 is clamped down by the artificial teeth 103. For that purpose, the teeth clamp base 303 may feature teeth sockets 304.

(10) The drain blocker 300 may feature a number of drain plugs 306 in a number that is preferably equal to the number of cleaning fluid drains 120, 121, 122. The drain plugs 306 are shaped in conjunction with the cleaning fluid drains 120, 121, 122 such that they are plugging them while the drain blocker 300 is in operational position.

(11) The drain blocker 300 may further feature a blocker rim 314 that may extend above the gum sealing interface 131 while the drain blocker 300 is in operational position. While the drain blocker 300 is in operational position with the cleaning fluid drains 120, 121, 122 plugged, cleaning fluid is pressurized accessed to the cleaning fluid access 118 across a cleaning access 311 of the drain blocker 300. The pressurized cleaning fluid that consequently builds up in the cleaning fluid cavity 125, squeezes out through the gum sealing interface 131. The blocker rim 314 extending above the gum sealing interface 131 may keep the squeezed out cleaning fluid in the proximity of the dental prosthesis 100.

(12) The dental prosthesis 100 with all its described inventive features may be fabricated and attached to the patient's gum 200 with well known techniques. Once attached, the gum sealing rim 111 is in a snug fit with the attachment gum 200. During regular cleaning of the dental prosthesis 100, a well known commercially available pressurized fluid dental cleaner may be employed to clean the artificial teeth 103 and artificial gum 105. During the course of such cleaning operation, the well known nozzle of such pressurized fluid dental cleaner may be positioned at the cleaning fluid access 118 initially without the drain blocker 300 in place. The injected cleaning fluid washes the cleaning fluid cavity 125 and exits via the cleaning fluid drains 120, 121, 122. Next, the drain blocker 300 is put into operational position and cleaning fluid is again injected into the previously cleaned cavity 125. The cleaning fluid builds up pressure inside the cleaning fluid cavity 125 since the cleaning fluid drains 120, 121, 122 are now blocked. Eventually the cleaning fluid pressure breaks through the gum sealing interface 131 and rinses the gum sealing interface 131 as well.

(13) Accordingly, the scope of the invention described in the Figures and Specification above is set forth by the following claims and their legal equivalents:
