SUBDIVIDABLE DENTAL ABSORBENT BLOCK

Abstract

An absorbent block of a length greater than a single tooth extraction site, the block subdividable into selected customized widths for application to a dental extraction site. The block may have a longitudinal notch in the surface pressed against the extraction site, or two opposed notches where corresponding upper and lower teeth are extracted. Pre-cut lines or surface marked lines indicate available widths for block subdivisions. The block may be curved as appropriate to align with partial or full arch teeth extraction procedures.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0032] Throughout the following description, specific details are set forth in order to provide a more thorough understanding to persons skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. The following description of examples of the invention is not intended to be exhaustive or to limit the invention to the precise form of any exemplary embodiment. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense.

[0033] The present invention is directed to an absorbent block that is subdividable into selected block divisions of a desired width. In this way, a user may generate customized block divisions sized appropriately for a specific dental extraction, from single teeth to full or even double arches. By allowing a user to selectively generate custom-sized absorbent block divisions, the coagulation may be further supported. As noted above, the block may be composed of any appropriate absorbent material, such as stacked gauze, and is preferably but not necessarily covered by an outer gauze cover.

[0034] Turning now to FIGS. 1a to 1c, a first exemplary embodiment is illustrated. An absorbent block 10 is shown, of a length 12 sufficient to be subdivided into various desired custom portions. The block 10 is provided with markings 14 which can be used by a user to select a desired total length appropriate for the width of a specific extraction site. The markings 14 are shown dividing the block 10 into equal parts of spacing 16 (which would be the widths of the block divisions when divided from the block 10), but the markings 14 could be given varying spacing. Further, although not shown, instead of or in addition to the markings 14 the block 10 could be provided with pre-cuts at the markings 14 to aid in division of the block 10. The block 10 is provided with an outer gauze cover 20.

[0035] The markings 14 divide the block 10 into portions 18. Each such portion 18 may be selected as a block division for use with an extraction site, or a series of adjacent portions 18 may be selected and removed together from the block 10 to form a larger width to match the target extraction site.

[0036] As can be seen in FIGS. 1a and 1c, the block 10 comprises a longitudinal notch 22 running the length 12 of the block 10. The notch 22 is configured for contacting and partially enclosing the extraction site when applied. The surface of the notch 22 may be further provided with an appropriate coagulant composition in liquid or gel form known to those in the art.

[0037] Turning now to FIGS. 2a and 2b, exemplary block divisions are shown. As noted above, a user would cut or otherwise divide the block 10 into customized portions of desired length to match the width of a target extraction site, and the block 10 may be provided with markings or pre-cuts to aid the user in this. As extraction sites, and the dental arches where they are located, can vary significantly in size, being able to generate customized block divisions of desired length is of utility. For example, a small block division 24, a medium block division 26 and a large block division 28 are illustrated, or varying lengths (and thus of varying block division widths to mate with a specific extraction site). Based on a specific target extraction site, the user could select which block division size would be most appropriate for the extraction site and divide the block 10 accordingly.

[0038] Turning to FIGS. 3a to 3c, this utility is further illustrated for extractions involving one or more teeth. FIG. 3a illustrates a situation where a single lower tooth has been extracted from an extraction site 30, and a block division 32 of suitable size can be removed from an absorbent block as described above to fit the specific gap width. FIG. 3b illustrates a situation where two adjacent lower teeth have been extracted from an extraction site 34, and a block division 36 of suitable size for a two-tooth gap can be removed from an absorbent block as described above to fit the specific gap width. FIG. 3c illustrates a situation where three adjacent lower teeth have been extracted from an extraction site 38, and a block division 40 of suitable size for a three-tooth gap can be removed from an absorbent block as described above to fit the specific gap width. In this way, the user may create various customized block division lengths matching the gap width of the specific extraction site.

[0039] It is also known in the art to extract all teeth from one or both the upper and lower dental arches. FIGS. 4a to 5b illustrate embodiments addressing such situations.

[0040] FIGS. 4a to 4b illustrate a single full arch extraction scenario. In this case, a curved absorbent block 42 may be used to match the curvature of the dental arch. FIG. 4a illustrates both sides of the block 42, with one of the sides provided with a curved notch 44. Further, the block 42 may have end portions 46 removed as described above to ensure that the total length of the block 42 matches the length of the dental arch. FIG. 4b illustrates the block 42 applied to a lower full arch extraction site 48.

[0041] Turning now to FIGS. 5a and 5b, a double full arch extraction scenario is illustrated. In this scenario, the teeth of both the upper and lower arches have been extracted, and an absorbent block 50 is prepared. The block 50 is again curved to match the shape of the upper and lower arches, and in this embodiment includes both upper and lower notches 52, 54 to mate with the extraction sites. FIG. 5b illustrates the block 50 pressed downwardly against the lower arch extraction site, with the upper notch 52 shown for illustration purposesthe patient would bite down on this upper notch 52 so that both the upper and lower arches engaged the block 50.

[0042] As can be seen, the use of straight or curved absorbent blocks, with guiding markings and/or pre-cuts at equal or varying distances can provide a dentist and/or patient with a customizable absorbent material solution that can be created to match the size of any extraction site. Unlike prior art solutions which teach set sizes and shapes of absorbent pads, embodiments according to the present invention may provide more comfortable and better-fitted products to aid in bleeding control and coagulation.

[0043] The foregoing is considered as illustrative only of the principles of the present invention. The scope of the claims should not be limited by the exemplary embodiments set forth in the foregoing, but should be given the broadest interpretation consistent with the specification as a whole.
