DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0036] Reference will now be made to various example embodiments of the present inventive concept, examples of which are illustrated in the accompanying drawings and illustrations. The exemplar embodiments are described herein in order to explain the present general inventive concept by referring to the figures. The following detailed description is provided to clarify the methods, apparatuses, and/or systems described herein. Accordingly, various changes, modifications, and equivalents of the methods, apparatuses, and/or systems described herein will be apparent to those of ordinary skill in the art.

[0037] A dental wound dressing 100 for dental surgical procedures, in accordance with various embodiments of the present general inventive concept, is shown generally in FIGS. 1-3B collectively. FIG. 1 depicts an exterior, perspective view of an example embodiment of the present general inventive concept. FIG. 2 depicts the same embodiment from FIG. 1, only from a side view with a cross-sectional cutting line C, designating a cross sectional view of the exemplar dressing shown in FIG. 1 as well as representative cross sectional views of alternative embodiments shown in FIGS. 3, 8, 9 & 10.

[0038] A dental dressing 100 for treating dental surgical procedures includes an exterior dressing pouch 101. The dressing pouch 101 can be a comprised of dressing material that adapts to various spatial requirements. For instance, one suitable dressing pouch 101 material is cotton gauze. Cotton gauze can be shaped, configured, and adjusted to conform to a given space. Moreover, cotton gauze is readily adaptable to the particular morphology and topology concerns of an exposed tooth socket, for example. Also important, gauze provides an appropriate medium to absorb blood and other exudate from the wound site. One skilled in the art will understand that the present general inventive concept is, of course, not limited to using gauze. For example, filter-paper, muslin, silk, cotton swabs, tulle, and the like, or any combination thereof, can also be utilized to achieve excellent clinical efficacy. In addition, dressing pouches containing topical agents and bio-ingredients such as, for example, hydrogel, alginate, hydrofibre, collagen, chitosan, or any combination thereof, can also be utilized. Other suitable dressing pouches will be apparent to those skilled in the art, and may be used without deviating from the scope or spirit of the present general inventive concept.

[0039] Contained substantially within the dressing pouch 101, is a cannabinoid-infused phytotherapeutic matrix 102. In the illustrated embodiment, the phytotherapeutic matrix 102 is substantially comprised of tea blends, turmeric and cannabinoids. More specifically, in the illustrated embodiment, the phytotherapeutic matrix 102 is substantially comprised of a substantially non-migrating mixture. Otherwise stated, the phytotherapeutic matrix 102 in the present embodiment is semi-rigid and effective at substantially retaining its shape under pressure.

[0040] Additionally, in some embodiments of the general present inventive concept, the phytotherapeutic matrix 102 can include a thermally active gel-like substance. Otherwise stated, the matrix 102 can substantially retain its temperature after introduction into hot or cold environments and subsequent removal therefrom. For example, the dressing can be placed in a refrigerator or freezer until cooled to a desired temperature. Upon removal from the cold environment, the dressing will substantially retain its cold temperature and subsequently provide cooling of the surgical site when placed within the oral cavity.

[0041] One skilled in the art will understand that the present general inventive concept is not limited to a phytotherapeutic matrix 102 that includes gel. On the contrary, other substances with similar properties can comprise the phytotherapeutic matrix 102. For instance, ammonium nitrate and water contained within a common housing member can combine to produce an endothermic reaction resulting in a cold product. Similarly, cannabinoid-infused clove oil can also be mixed into the matrix and stored in a cold environment. Of course, in order to create a phytotherapeutic matrix 102, the above-mentioned ingredients will have to be contained in a porous dressing pouch that can be readily inserted into an oral cavity and engage a surgical site, while also substantially fitting between contiguous teeth. Further, in some embodiments, the porous dressing pouch can be relatively pliable, so as to prevent damage to teeth exerting pressure on the dental dressing 100. One skilled in the art will recognize that several polymer-based materials can also be utilized to create the porous dressing pouch that is adaptable for insertion into an oral cavity. One skilled in the art will also understand, however, that the present general inventive concept is not limited to the above-mentioned substances. Other substances capable of retaining a cold temperature and being contained within a porous dressing pouch can also be used without departing from the scope or spirit of the present general inventive concept.

[0042] FIG. 3A depicts a cross-sectional view of an example embodiment of the present general inventive concept with the phytotherapeutic matrix 102 in the general shape of a U, but having tapered and angled side arms. Otherwise stated, the embodiment illustrated in FIG. 3A includes a cover portion to cover an exposed tooth socket, for example, and two tapered arm members angularly extending from opposing sides of the socket cover segments. FIG. 3B depicts a cross-sectional view of another example embodiment of the present general inventive concept with the phytotherapeutic matrix 102 in the general shape of a U without incorporating tapered or angled arm members. Otherwise stated, the embodiment in FIG. 3B includes a socket cover portion and two non-tapered arm members perpendicularly extending from the cover portion.

[0043] When engaging an exposed tooth socket, the phytotherapeutic matrix 102 can be oriented in such a way that it substantially covers and surrounds the exposed tooth socket while also fitting between contiguous teeth. More specifically, when engaging an exposed tooth socket, the cover portions of the present example embodiments can sit on top of, or be disposed directly beneath, one or more exposed tooth sockets, while the two tapered arm members laterally flank one or more exposed tooth sockets on opposing sides of the oral epithelium. Otherwise stated, the phytotherapeutic matrix 102 can superpose the exposed tooth socket as well as engage both sides of the oral epithelium and gingival tissue proximate the exposed socket, with one arm member engaging the facial surface of the proximate gum tissue, and the other arm member engaging the lingual surface of the proximate gum tissue.

[0044] The primary difference between the embodiment illustrated in FIG. 3A and the one illustrated in FIG. 3B is shape. The angled and flared arm members of the therapeutic matrix in FIG. 3A can provide a better fit for individuals with larger-sized gums. Depending on the flexibility/rigidity of the matrix and pouch comprising the dressing in the illustrated embodiment, the overall shape of the phytotherapeutic matrix 102 can remain substantially the same even with force exerted by the opposite jaw. Otherwise stated, in some embodiments the phytotherapeutic matrix 102 can be semi-rigid so as to substantially prevent significant flexing in the shape of the phytotherapeutic matrix 102. Thus, for individuals with larger gums, the angled and tapered arm members can facilitate an improved fit, while still permitting the dressing to remain substantially between contiguous teeth. Further, the tapered arm members can also permit the inclusion of additional absorbent material. Otherwise stated, tapered arm members occupy less volume than the non-tapered arm members of FIG. 3B, and therefore permit the absorbent material to occupy the excess volume that would be otherwise be occupied by the non-tapered arm members. Providing additional absorbent material to the dental dressing 100 will allow the dental dressing 100 to generally absorb more exudate from the wound site. While the foregoing description is generally directed specifically to an exposed tooth socket, it should be understood by anyone of ordinary skill in the art that the exemplar dental dressing 100 described in the previous paragraphs is suitable for use over any iatrogenic trauma or surgical site and is not in any way limited to exposed tooth sockets.

[0045] FIGS. 4-7 depict an example embodiment of the present general inventive concept engaging an exposed tooth socket. FIG. 4 depicts an exploded view of an example dental dressing 100 engaging an exposed tooth socket 401. FIGS. 5-7 depict an example dental dressing 100 ensconced within an exposed tooth socket 401. Specifically, FIG. 6 depicts a more detailed view of the embodiment portrayed in FIG. 5, and FIG. 7 depicts a cross-sectional view of the embodiment portrayed in FIG. 6.

[0046] Each exposed tooth socket 401, and for that matter any iatrogenic trauma, contains particular morphological and topological concerns. For example, an exposed tooth socket 401 generally contains a cavity, into which the root of a tooth is generally disposed and secured to the alveolar (jaw) bone with periodontal ligaments. Further, the gingival tissue immediately abutting and surrounding the cavity has distinct contours and shapes. For instance, the marginal and attached gingiva contain depressions, grooves, and indentations. In this regard, the dressing 100 can substantially conform to the topology and morphology of the exposed tooth socket 401 and proximate gingival and epithelial tissue, and can be compressed to apply appropriate pressure for promoting hemostasis. The dressing pouch 101 can also be compressed in such a way that part of it actually extends into the cavity in the open socket 401. The pressure applied by the dressing pouch 101 substantially assists the wound site in achieving hemostasis.

[0047] Additionally, the dressing pouch 101 can be compressed against and into the exposed tooth socket 401 to fully engage the cannabinoid-infused phytotherapeutic matrix 102 with the exposed tooth socket 401. The phytotherapeutic matrix 102 substantially covers and encompasses the exposed tooth socket and proximate tissue to relieve pain and reduce inflammation, while fitting substantially between contiguous teeth. The therapeutic effectiveness of the phytotherapeutic matrix 102 is significantly influenced by its proximity to the exposed tooth socket and proximate soft tissue. The proximity of the phytotherapeutic matrix 102 to the exposed tooth socket is directly affected by the amount and degree of compression of the dressing pouch 101 between the phytotherapeutic matrix 102 and the exposed socket.

[0048] Referring now to FIGS. 6 & 7, the dressing pouch 101 has substantially conformed to the exposed tooth socket 401. These figures illustrate how the dressing pouch 101 can compress against and into an exposed tooth socket 401 to achieve substantial proximity between the phytotherapeutic matrix 102 and the exposed tooth socket 401 and proximate soft tissue. Similarly, dressing 100 will likewise conform to the complex anatomy and topology of any iatrogenic trauma or surgical site. Accordingly, in the embodiments where the phytotherapeutic matrix 102 is thermally active, cold therapy can be applied to the exposed tooth socket 401, or surgical site, and proximate soft tissue by virtue of the proximity of the phytotherapeutic matrix 102. The dressing pouch 101 along with matrix material 102 absorbs any exudate from the wound, such as serosanguineous fluid, and provides pressure to the socket and proximate tissue to promote hemostasis. Further, as depicted in the embodiment illustrated in FIG. 7, the side arms of the dressing 100 can extend beyond the tooth line to engage both sides of the gingival tissue and oral epithelium proximate the exposed tooth socket 401. Otherwise stated, the side arms of the dressing 100 can extend down below the tooth line and flank both sides of the exposed tooth socket to engage proximate gum tissue, thereby applying therapy to the blood vessels in the gum tissue below the extraction site. This helps relieve pain and decrease inflammation associated with the exposed tooth socket.

[0049] FIGS. 8-9B depict example embodiments of the phytotherapeutic matrix 102, in accordance with various embodiments of the present general inventive concept. More specifically, FIG. 8A depicts an example embodiment with the phytotherapeutic matrix 102 having tapered and angled side arms. A moisture-liberating element 801 is also included, embedded and contained substantially within the dressing pouch 101. FIG. 8B depicts an example embodiment with the phytotherapeutic matrix having side arms disposed substantially perpendicularly from the socket cover portion. FIG. 8B also includes a moisture-liberating element 801 embedded and contained substantially within the dressing pouch 101. FIGS. 9A & 9B depict both example embodiment phytotherapeutic matrix 102 discussed above, but further includes a topical agent element 901 also embedded and contained substantially within the dressing pouch 101.

[0050] In the embodiments illustrated in FIGS. 8A & 8B, moisture-liberating elements 801 are embedded and contained substantially within the dressing pouch 101, substantially adjacent to the phytotherapeutic matrix 102. In the illustrated embodiments, the moisture-liberating element 801 is comprised of hydrogel. It will be understood that hydrogel is comprised of a network of hydrophilic polymer chains. Over time, the hydrogel elements 801 in the illustrated embodiments release moisture to the exposed tooth socket and proximate tissue. It is generally accepted that keeping the exposed sockets moist and clean may help prevent alveolar osteitis, or dry sockets. Although the oral cavity is substantially moist already, the dressing pouch 101 and matrix material 102 can have a tendency to cause dryness by absorbing a significant portion of the proximate fluid, thereby depriving the wound site and proximate tissue of moisture. Incorporating a hydrogel element 801 can help ensure that the exposed tooth socket remains moist. Similarly, other moisture-liberating elements 801 containing hydrocolloids, hydrofibres, and/or any combination thereof can also be used to achieve similar results without departing from the scope or spirit of the present general inventive concept.

[0051] In the embodiments depicted in FIGS. 9A & 9B, a topical agent element 901 is included. The topical agent elements 901 can be comprised of myriad different substances that can be applied topically to the wound site to promote healing and/or relieve pain and inflammation. For example, cannabinoid-infused clove oil (eugenol) can be included in the element 901 to provide pain relief and prevent infection. In some embodiments, medications like benzocaine, iodophorm, soluble aspirin, zinc oxide, or any combination thereof, can be included in the topical agent element 901. Topical agent elements 901 containing analgesics, such as eugenol, can be particularly effective immediately following a surgical procedure and in particular tooth extraction when pain is almost always present. Analgesics and other medications are also effective in cases when dry sockets form after tooth extraction. One skilled in the art will recognize that other topical substances can be included without departing from the scope or spirit of the present general inventive concept.

[0052] In the illustrated embodiments, the moisture-liberating elements 801 are disposed between the topical agent elements 901 and the phytotherapeutic matrix 102, all embedded and contained substantially within the dressing pouch 101. Most topical agents envisioned to be included in the elements 901 are water soluble. Therefore, disposing the moisture-liberating element 801 between the topical agent and the phytotherapeutic matrix 102 will ensure that the topical agent element 901 becomes moist, thus facilitating topical application to the surgical site or exposed tooth socket 401. Furthermore, the therapeutic effectiveness of the topical agent element 901 is optimized by disposing it proximate to the wound site. However, one skilled in the art will understand that the relative disposition of the moisture-liberating elements 801 and the topical agent elements 901 described herein is non-limiting.

[0053] In the embodiments illustrated in FIGS. 10A-10D, the phytotherapeutic matrix 102 is configured, generally, as an H. FIG. 10A depicts an example embodiment of matrix 102 with tapered and angled side arms, whereas FIG. 10B depicts another example embodiment phytotherapeutic matrix 102 with non-tapered, substantially perpendicular arm members. Both of the example embodiments illustrated in FIGS. 10A & 10B include hydrogel elements 801A & 801B and topical agent elements 901A & 901B. These embodiments accommodate substantially aligned, maxillary and mandibular iatrogenic trauma particularly including exposed tooth sockets. Otherwise stated, the present embodiments can provide therapy following an extraction of substantially aligned mandibular and maxillary teeth. For example, oral, hockey injuries frequently effectuate or necessitate extraction of substantially aligned maxillary and mandibular teeth. The present embodiments provide a therapeutic option for those injuries, in particular, contained within a single wound dressing 100.

[0054] FIGS. 10C & 10D portray cross-sectional views of example embodiment, H-shaped dental wound dressings 100 engaging substantially aligned maxillary and mandibular exposed tooth sockets. The example embodiment depicted in FIG. 10C includes only a phytotherapeutic matrix 102 embedded and contained substantially within a dressing pouch 101, whereas the example embodiment in FIG. 10D includes a phytotherapeutic matrix 102, hydrogel elements 801A & 801B, and topical agent elements 901A & 901B embedded and contained substantially within a dressing pouch 101. Proximate gum tissue is indicated at 1006A & 1006B. As shown, the side arms of the phytotherapeutic matrix 102 flank the lingual and facial surfaces of the proximate gum tissue 1006A & 1006B and provide therapy to the blood vessels contained therein.

[0055] FIGS. 11-14 depict example embodiment dental wound dressings 100 that engage an extensive surgical site, for example, a plurality of exposed tooth sockets. For instance, FIG. 11 depicts an example embodiment wound dressing 100 engaging substantially aligned maxillary 1101 and mandibular 1102 tooth sockets. More specifically, the dental dressing 100 in the illustrated embodiment is engaging substantially aligned and exposed third molar, or wisdom tooth, sockets. This embodiment accommodates the H-shaped example embodiment phytotherapeutic matrix 102 depicted in FIGS. 10A & 10B. The presently depicted embodiment is installed within a patient's oral cavity by placing the dressing 100 in the desired location while the oral cavity is fully extended or open. The patient will then close the oral cavity to the extent permitted by the dressing 100 to compress the dressing pouch 101 against the exposed tooth sockets and proximate tissue, thereby substantially engaging the phytotherapeutic matrix 102 with the exposed sockets and proximate tissue.

[0056] FIG. 12 depicts an example embodiment wound dressing 100 engaging an extended surgical site, for example, a plurality of adjacent mandibular 1102 tooth sockets. The illustrated embodiment's phytotherapeutic matrix 102 contains the same, substantially U shaped cross sections portrayed in FIGS. 3A & 3B, but is elongated to cover a plurality of adjacent, exposed tooth sockets. Like the embodiment illustrated in FIG. 11, installation into a patient's oral cavity can be achieved by opening the oral cavity, inserting the dressing 100 into the selected location, and gently closing the oral cavity to compress the dressing pouch 101 and matrix 102 against and into the exposed sockets.

[0057] FIG. 13 depicts an example embodiment wound dressing 100 simultaneously engaging a plurality of adjacent, substantially aligned, maxillary 1101 and mandibular 1102 exposed tooth sockets. In the present embodiment, the phytotherapeutic matrix 102 contains an H-shaped cross section illustrated in either FIG. 10A or FIG. 10B, but is elongated to accommodate a plurality of adjacent tooth sockets.

[0058] FIG. 14 depicts an example embodiment dental wound dressing 100 engaging an entire row of exposed, mandibular 1102 tooth sockets. In this regard, the presently illustrated embodiment resembles a conventional mouthpiece. The presently illustrated embodiment can be used following the extraction of an entire row of teeth, frequently as part of the preparation for installing dentures. One skilled in the art will recognize that the present embodiment can also engage a row of exposed, maxillary 1101 tooth sockets. Thus, the present embodiment provides a therapeutic option for the pain associated with a full row tooth extraction in a single dressing 100.

[0059] In some instances, a patient has both rows of teeth extracted. Otherwise stated, it is possible to have both maxillary 1101 and mandibular 1102 full row extractions at substantially the same time. Therefore, in some embodiments of the present general inventive concept, two dental dressings 100 having U-shaped cross-sections can each independently engage the maxillary row 1101 and mandibular row 1102. In this embodiment, because two distinct dental dressings 100 are being used, a straw or other feeding apparatus can be inserted into the oral cavity between the two dental dressings 100. On the other hand, in other embodiments, one dental dressing having an H-shaped cross section can engage both the maxillary and mandibular row of exposed tooth sockets. However, in this embodiment, a straw or like device will not be able to be inserted into the patient's oral cavity because of the occluding dental dressing engaging both the upper and lower rows of tooth sockets (or surgical site).

[0060] The embodiments described herein provide a dental dressing 100 for an iatrogenic trauma or (extended) surgical site including a phytotherapeutic matrix 102 embedded and contained substantially within a dressing pouch 101. The dressing pouch 101 can be adaptable to conform to various shapes and contours as required by the particular anatomy and underlying topology. The phytotherapeutic matrix 102 can be sized and shaped to engage an exposed tooth socket and flank opposing sides of the oral epithelium, while fitting substantially between contiguous teeth. In some embodiments, the cannabinoid-infused phytotherapeutic matrix 102 includes a semi-rigid, substantially non-migrating thermally active gel-like material contained within a housing member. Following a tooth extraction, for example, patients can place the dental dressing 100 in a cold environment so that the dressing becomes cold. Subsequently, the patient can remove the dental dressing 100 from the cold environment and introduce it into their oral cavity. The dressing pouch 101 can be compressed into the exposed socket, thereby engaging the embedded phytotherapeutic matrix 102 with the exposed tooth socket. The dressing pouch 101, and the applied pressure, will help absorb exudate and promote vasoconstriction, while the cold phytotherapeutic matrix 102 will reduce inflammation, promote vasoconstriction, and relieve pain.

[0061] In other embodiments, the phytotherapeutic matrix 102 includes ammonium nitrate and water substantially contained within a polymer-based housing member. Patients/caregivers can cause the phytotherapeutic matrix 102 to become cold by effectuating an endothermic reaction with the ammonium nitrate and water, by, for example, shaking the matrix 102 or inserting water into a housing member that already contains ammonium nitrate. Similarly, after the endothermic reaction takes place to produce a cold phytotherapeutic matrix 102, the dental dressing 100 can be placed within the patient's oral cavity in the same manner described herein above.

[0062] In some embodiments of the dental dressing 100, the phytotherapeutic matrix 102 is shaped substantially like a U, and sized to engage, for example, one exposed tooth socket. In other embodiments, the phytotherapeutic matrix 102 is shaped generally like a U, but with tapered side members angularly extending from a cover portion. In yet other embodiments, the phytotherapeutic matrix 102 has a U-shaped cross section, but is elongated to substantially engage an extended surgical site, for example, a plurality of adjacent, exposed tooth sockets. In yet other embodiments, the phytotherapeutic matrix 102 is shaped generally like an H, with perpendicular or angled, tapered or non-tapered side members extending from a cover portion, to substantially engage substantially aligned maxillary 1101 and mandibular 1102 exposed tooth sockets. In other embodiments, the phytotherapeutic matrix 102 has an H-shaped cross section, but is elongated to substantially engage an extended surgical site, for example, a plurality of adjacent, substantially aligned maxillary and mandibular exposed tooth sockets.

[0063] In some embodiments, the dental dressing 100 includes a hydrogel element 801 embedded and contained substantially within the dressing pouch 101. In other embodiments, the dental dressing 100 includes an element 801 substantially comprised of hydrogel, hydrocolloid, hydrofibre, and/or any combination thereof. One skilled in the art will recognize that other, moisture-liberating elements can also be used without deviating from the scope or spirit of the general present inventive concept. These moisture-liberating elements 801 are particularly applicable in instances where a dry socket evolves after tooth extraction.

[0064] In some embodiments, the dental dressing 100 includes an active topical agent element 901. In other embodiments, the active topical agent element 901 includes medications like eugenol, benzocaine, iodophorm, soluble aspirin, zinc oxide, or any combination thereof. One skilled in the art will recognize that the present general inventive concept is not limited to the use of the specific substances described herein, but can also encompass other, topical agents that can be included in the element 901 for topical application to an exposed tooth socket.

[0065] Numerous variations, modifications, and additional embodiments are possible, and accordingly, all such variations, modifications, and embodiments are to be regarded as being within the spirit and scope of the present inventive concept. For example, regardless of the content of any portion of this application, unless clearly specified to the contrary, there is no requirement for the inclusion in any claim herein or of any application claiming priority hereto of any particular described or illustrated activity or element, any particular sequence of such activities, or any particular interrelationship of such elements. Moreover, any activity can be repeated, any activity can be performed by multiple entities, and/or any element can be duplicated.

[0066] The above described embodiments are set forth by way of example and are not for the purpose of limiting the scope of the present inventive concept. It will be readily apparent that obvious modifications, derivations and variations can be made to the embodiments without departing from the scope of the present inventive concept. Accordingly, the claims appended hereto should be read in their full scope including any such modifications, derivations and variations.
