DETAILED DESCRIPTION

[0024] The instant devices and approach provide a way for cleaning interproximal surfaces and contact areas between teeth using a prophylaxis strip that has an added structural support longitudinally that still allows the end of the strip to be inserted between teeth to push foreign material from between the teeth.

[0025] In order to understand the advantages of the instant devices it is helpful to examine current techniques for using prophylaxis strips. FIG. 1 (Prior Art) shows the standard use of a prophylaxis strip 100 that is used to clean the surface between someone's teeth 110A, 110B by pulling it back and forth by grasping the two ends 102,104. This is used in a similar fashion to dental floss.

[0026] In the case of FIG. 1 (Prior Art) depending on the material selected it is not possible to use the end of the prophylaxis strip to push a foreign object from between a person's teeth. It is only possible to draw a foreign object out by either dragging the strip over the top of the object or by getting the strip between one of the person's teeth and the object and then using the side of the strip to drag the foreign object out. The latter of technique may or may not be possible depending on the size of the foreign object and the former technique, if not successful in removing the object, may simply push the object closer to the patient's gums.

[0027] In contrast, the instant devices provide structural support along the longitudinal length of prophylaxis strip and leaves the ends clear such that the ends of the prophylaxis strip can be used to push foreign objects from between the person's teeth.

[0028] FIGS. 2A and 2B shows, in simplified form, the use of a prophylaxis strip to remove a foreign object 210A, stuck between a person's teeth 110A, 110B. In FIG. 2A the end 206 of the prophylaxis strip assembly 200 is being used to push a foreign object 210A lodged between someone's teeth 110A, 110B. In FIG. 2B, the foreign object 210B has been successfully dislodged. The foreign object 210B was dislodged by using an end 206 of a prophylaxis strip assembly 200 to push against the foreign object 210A. The prophylaxis strip assembly 200 is comprised of a prophylaxis strip 202 and an added structural support 204 along the longitudinal length of the prophylaxis strip 202, such that a portion the end 206 of prophylaxis strip 202, approximately the height of a person's teeth or greater, is uncovered by the added structural support 204. The uncovered portion defining a depth of the prophylaxis strip 209, which is the distance from the structural support 204 to the base of the prophylaxis strip 209.

[0029] This configuration is advantageous because it provides enough structural support such that objects can be pushed from between a person's teeth while still allowing flexible materials to be used for the prophylaxis strip so that is can bend around the contours of the patient's teeth to allow the walls of the teeth to be effectively cleaned. [Note: the structural supports herein need not be configure to produce a consistent depth of the prophylaxis strip and bowed configuration as well as angled configuration are also anticipated, the point being that at least some portion of the end of the prophylaxis strip is unblocked by the structural support.

[0030] FIG. 3A-3C shows, in simplified form, alternate versions 300A, 300B, 300C of prophylaxis strip assembly 200 from FIG. 2A-2B, with the difference being that rather than having a square end 206 (substantially perpendicular to the base 209) on both sides, prophylaxis strip assembly 300A in FIG. 3A has a hooked end 400 on one side, the prophylaxis strip assembly 300B in FIG. 3B has an end 410 angled outward on one side (an acute angle with respect to the base), and the prophylaxis strip assembly 300C in FIG. 3C has an end 320 that is angled inward on one side (an obtuse angle with respect to the base). In this regard, it should be understood that the various ends 206, 300, 310, 320 are representative of typical end configurations for purposes of understanding and that various end combinations could be used at different ends of the strip. It is to be understood that other end configuration, whether standard or proprietary, can be used to the same or similar effect for pushing (or prying) foreign objects from between someone's teeth. Again, the important aspect being the ability to remove a foreign object by using the end, not the particular configuration of the end used.

[0031] While a one-sided prophylaxis strip offer numerous advantageous, a multi-sided prophylaxis strip adds even more advantageous. FIG. 4A-4B show, in simplified form representative two-sided prophylaxis strip assemblies. FIG. 5 shows, in simplified form representative three-sided prophylaxis strip assembly. FIG. 6 shows, in simplified form representative four-sided prophylaxis strip assembly. The advantage being that with multi-sided configuration the various sides of the assembly can have the same or different properties. A few examples of variations are that the thickness of the strip could be varied from side to side, which could advantageously accommodate varying gaps between teeth and/or provide different stiffness/flexibility of the strip; the material of the strip could be varied from side to side, which could also advantageously be used to provide varying stiffness/flexibility of the strip; the ends of the strips could be different combinations; the depth of the strip could be varied, which advantageously allows different heights of the teeth to be accommodated; and the texture of the strip could be varied, which advantageously allows the strip to perform different functions.

[0032] FIG. 4A shows a two-sided prophylaxis strip assembly 400A that has two sides 410, 415 separated by a structural support 420. On the one side 410 are a plurality of holes 430, which advantageously allow material to be gripped within the holes and aids in removing foreign matter, particularly small particulate, from between the teeth. Additionally, some of the holes 430 are shown as filled with fill material 440. A few examples of fill material 440 that might be used included abrasives, toothpaste, whitening agents, and flavorings to name a few possibilities. The other side 415 is shown with texture 450 added to the strip, which advantageously can be used to produce different cleaning properties. The texture 450 is shown as running perpendicular to of the support structure; however, other textures such as parallel, diagonal, crosshatched, and grit finishes are also anticipated.

[0033] FIG. 4B also shows a two-sided prophylaxis strip assembly 400B that has two sides 460, 470 separated by a structural support 480. The difference being that while the structural support 420 of FIG. 4A is shown as bisecting the two sides 410, 415, the structural support 480 of FIG. 4B is shown as attached to the surface of the prophylaxis strip assembly 400B and thus creating the two sides.

[0034] Additionally, in FIG. 4B each side 460, 470 is shown as having different depths 465, 475, which, as previously mentioned can be advantageously utilized to accommodate different teeth heights that may occur throughout someone's mouth or to accommodate differences between users.

[0035] It should be noted that the methods of attachment of any of the structural supports to the prophylaxis strip (or vice versa) presented herein include both standard and proprietary techniques such as a physical adhesive; chemical bonding, heat sealing, ultra sonic bonding, and (with the exception of FIG. 4B) mechanical attachments (e.g. a press fit). In this regard, it should be understood that the methods of attachment are representative of typical, known methods of attachment for purposes of understanding. It is to be understood that other methods of attachment whether standard or proprietary can be used to the same or similar effect for attaching the prophylaxis strip to the structural support, again, the important aspect being the ability to the prophylaxis strip to the structural support, not the particular methods of attachment or protocol used.

[0036] Additionally, it is worth pointing out that the structural supports presented herein need not necessarily be a separate component and may simply be a thicker areas of the prophylaxis strip or represent areas of the prophylaxis strip that have been folded over and then bonded. The point being that the structural support in combination with the prophylaxis strip provide enough rigidity such that the end of the prophylaxis strip can be used to push objects from between someone's teeth.

[0037] Finally, it is to be understood that various different variants of the invention, including representative embodiments and extensions have been presented to assist in understanding the invention. It should be understood that such implementations are not to be considered limitations on either the invention or equivalents except to the extent they are expressly in the claims. It should therefore be understood that, for the convenience of the reader, the above description has only focused on a representative sample of all possible embodiments, a sample that teaches the principles of the invention. The description has not attempted to exhaustively enumerate all possible permutations, combinations or variations of the invention, since others will necessarily arise out of combining aspects of different variants described herein to form new variants, through the use of particular hardware or software, or through specific types of applications in which the invention can be used. That alternate embodiments may not have been presented for a specific portion of the description, or that further undescribed alternate or variant embodiments may be available for a portion of the invention, is not to be considered a disclaimer of those alternate or variant embodiments to the extent they also incorporate the minimum essential aspects of the invention, as claimed in the appended claims, or an equivalent thereof.
