DETAILED DESCRIPTION
[0033] Aspects of the invention are disclosed in the following description and related drawings directed to specific embodiments of the invention. Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description, discussion of several terms used herein follows.
[0034] As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiments are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention”, “embodiments” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage or mode of operation.
[0035] Generally referring to the figures, a method, system and apparatus for a foolproof periodontal sulcus brush and intrasulcular medicament applicator may be shown and described. The foolproof periodontal sulcus brush and intrasulcular medicament applicator can be formed in a variety of designs and utilize various combinations of handles, necks, heads, and bristles—to provide desired oral hygiene and/or intrasulcular medicament application functions. Also, all heads could be releasably attached and have couplings for mating to a motorized or manual handle.
[0036] Referring now to FIGS. 1-6, a double-headed foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 may be shown. The brush/applicator 10 may be formed out of any of a variety of materials, including, but not limited to, plastics, composites, or any other desired material. The foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 can have a handle 12 formed as a body and a gripping portion 14, neck portions 20, 22, 24, 26, and head portions 28, 30. A central body or handle 12 of the double-headed foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 may be substantially flat, square, rectangular, cylindrical, or any combination thereof. Further, the heads 28, 30 and necks 20, 22, 24, 26 may be formed in any shape. For example, the heads 28, 30 and necks 20, 22, 24, 26 may have cylindrical, circular, or rounded shapes, to provide for comfort in use in a mouth. The neck 20, 22, 24, 26 and/or head 28, 30 portions may be substantially curved, as desired, and as shown in exemplary FIGS. 1, 2, and 3. Further, the heads 28, 30 may include a plurality of bristle tufts 32. The bristle tufts 32 may be utilized in any number, for example three bristle tufts, and may be spaced apart substantially equidistantly. It may further be appreciated that the number of bristles tufts may be from one to ten tufts, as desired and depending, for example, on which species and oral region the foolproof periodontal sulcus brush and intrasulcular medicament applicator is being used. The spacing may be about 0.5 mm to about 4 mm, for example. The bristles 32 may have any length, for example about 5 mm to about 10 mm or more, as desired. Total length of the heads 28, 30 of the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 may be about 6 mm to about 30 mm or more, as desired. Further, the two heads of the double-headed foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 may be releasably coupled to each other or a handle, permanently affixed to each other or a handle or otherwise coupled. For example, a first head on a double-headed foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 may be swapped out for a different head having a different neck angle or combination of neck angles. Such applications may be beneficial for use or treatment with different types of jaw structures or animals, replacing brush/applicator heads due to wear, or providing varied treatment to an intended user or animal. Additionally, one or both heads could be releasably attached and have couplings for mating one or both brush/applicator heads to a motorized or manual handle.
[0037] Still referring to exemplary FIGS. 1-6, on both ends of the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 handle 12, there are necks 20, 22, 24, 26 which connect, respectively, to the brush/applicator heads 28, 30. The proximal 20, 22 necks both extend away—in opposite directions, from the handle 12, along its longitudinal axis 46, and thus laterally offset the brush/applicator heads 28, 30 from the handle 12. In addition, each brush/applicator head 28, 30 may have a distal neck 24, 26 that allows for one or both heads 28, 30 to be vertically-offset, from the handle 12, by virtue of multiple bends. Each distal neck 24, 26 of the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 may have a departure angle—Angle X, from the longitudinal axis 46 of the handle 12 and proximal neck 20, 22 of about 75 degrees to about 105 degrees, for example about 90 degrees and may then have a second bend, with a departure angle Angle Y, into the into the longitudinal axis 48 of the head 28, 30 of the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10, of about 75 degrees to about 105 degrees, for example about 90 degrees, to provide for enhanced utility in navigating the mouth of an intended user or animal. Each head 28, 30 may have a plurality of bristle tufts 32 projecting from it; the bristle tufts 32 are most ideally oriented in a single row, and they may be oriented perpendicular to the plane 50 of the distal necks 24, 26 and handle 12. This can be further illustrated in exemplary FIGS. 7-8, showing foolproof periodontal sulcus brush and intrasulcular medicament applicators 10, in use. As demonstrated in these figures, the handle 12, head 28, 30, neck 20, 22, 24, 26, and bristle 32 orientations allow for the cleaning of gingiva, teeth, implants, and prostheses and the application of medicaments, in varying dental scenarios, that could not have previously been cleaned or had medicaments applied, without significant irritation from, or general ineffectiveness of, currently available toothbrushes or other oral care brushes. The offset heads 28, 30 permit the bristles 32 to effectively reach the lingual sulci of the posterior teeth, without the handle 12 contacting the anterior teeth, and inhibiting such access, as is typical of other known oral care brush designs, especially those without offset heads. This configuration also permits the bristles 32 to fit underneath a prosthesis 62. As shown in these exemplary figures, such head and neck designs can allow for the cleaning of gingiva, teeth, implants, and/or prostheses that were previously inaccessible or otherwise positioned in such a manner that known toothbrushes and other oral care brushes could not access them properly, for cleaning, or for the application of intrasulcular medicaments.
[0038] Referring further to FIGS. 1-6, there is shown an exemplary embodiment of a double-ended foolproof periodontal sulcus brush and intrasulcular medicament applicator 10. FIGS. 1-5 show a foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 having a handle 12 and brush heads 28, 30 attached to both ends of the handle 12. More specifically, the handle 12 includes a gripping portion 14 that is substantially linear and defined by a longitudinal axis 46. In a preferred embodiment, the handle 12 and gripping portion 14 have a planar shape with a circular cross section. The circular cross section of the handle 12 provides an ergonomic design for gripping and maneuvering the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 during a brushing session. In addition, the circular cross section provides a means for an individual with a fixed prosthesis to grip the toothbrush so that bristles 32 may be freely oriented, relative to fitting under a prosthesis, (see FIG. 7), as well as also being able to fit under the gum line, and into the gingival sulcus and/or peri-implant crevice—at an entirely different angle, (see FIG. 8), in order to yield optimal cleaning and efficiency. Although it is preferred that the handle 12 and gripping portion 14 have a circular cross section—to permit all angulations for access to the intended anatomical and prosthetic targets, other cross-sectional shapes can be used. For example, the handle 12 and gripping portion 14 may have a planar shape with a rectangular cross section. In another embodiment, the handle 12 and gripping portion 14 may comprise a planar shape with a square cross section. Each cross sectional design—circular, rectangular, or square—of the handle 12 contributes to how the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10 is held, and has its own advantages in facilitating optimal cleaning of the teeth, implants, gingival sulci, peri-implant crevices, and prostheses. Moreover, each design provides a left or right handed individual means to comfortably grip and control the foolproof periodontal sulcus brush and intrasulcular medicament applicator 10.
[0039] In a further exemplary embodiment, and referring now to exemplary FIG. 9, it may be appreciated that the foolproof periodontal sulcus brush and intrasulcular medicament applicator 120 may have varying neck 124 lengths—for varying degrees of vertical offset of the head 126, to conform to varying oral hygiene and medicament application objectives. The bristles 128 may also be oriented obliquely—Angle A, to the plane 123 of the handle 122 and distal neck 124 and head 126, especially if that may facilitate entry into the gingival sulcus at the recommended 45 degree angle to the labial and lingual surfaces of the teeth, at the gum line—for a human or for a caretaker of a human or other species, and/or for a particular region of the mouth. These can be varied, as desired, according to the exemplary embodiments described herein. This can be further illustrated in exemplary FIG. 10, showing a foolproof periodontal sulcus brush and intrasulcular medicament applicator 120, in use.
[0040] Referring now to FIG. 11, it is an exemplary image of a foolproof periodontal sulcus brush and intrasulcular medicament applicator 120 in use—with its bristles 128 penetrating into the gingival sulcus 134,—beginning at an approximate 45-degree angle to the surface of the tooth 136, for entry.
[0041] Referring now to FIGS. 12-14, a single-headed foolproof periodontal sulcus brush and intrasulcular medicament applicator 140 may be shown. The brush/applicator may be formed out of any of a variety of materials, including, but not limited to, plastics, composites, or any other desired material. The foolproof periodontal sulcus brush and intrasulcular medicament applicator 140 can have a handle 142 with a gripping portion 144, neck portions 148, 150, and a head portion 152. The handle 142 of the single-headed foolproof periodontal sulcus brush and intrasulcular medicament applicator may be substantially flat, square, rectangular, cylindrical, or any combination thereof, and may be solid or hollow. Further, the head 152 and necks 148, 150 may be formed in any shape. For example, the head 152 and necks 148, 150 may have cylindrical, circular, or rounded shapes, to provide for comfort in use in a mouth. The neck 148, 150 portions may be substantially curved, as desired, and as shown in exemplary FIGS. 12-13. And the neck 148, 150 portions may offset the head 152 forward of the handle 142, to improve access to the gingival sulci, which are obstructed from being properly accessed and entered, by currently available toothbrushes and other oral care brushes. Further, the head may include a plurality of bristle tufts 154. The bristle tufts may be utilized in any number, for example five bristle tufts or three bristle tufts, and may be spaced apart substantially equidistantly. It may further be appreciated that the number of bristles tufts may be from one to ten tufts, as desired and depending, for example, on which species and oral region the foolproof periodontal sulcus brush and intrasulcular medicament applicator 140 is being used. The spacing may be about 0.5 mm to about 4 mm, for example. The bristles 154 may have any length, for example about 5 mm to about 10 mm or more, as desired. Total length of the head 152 of the foolproof periodontal sulcus brush and intrasulcular medicament applicator 140 may be about 6 mm to about 30 mm or more, as desired. Referring now to FIG. 14, it is an exemplary image of a single-headed, square cross-sectional-handled, foolproof periodontal sulcus brush and intrasulcular medicament applicator 140, with the plane 146 of its bristles oriented/offset at a 45-degree angle—Angle B, to the sides of the handle, to facilitate achieving the 45-degree recommended angle—for gingival sulcus entry, when the handle is held with two sides paralleling the horizon. Further, the head 152 of the single-headed, foolproof periodontal sulcus brush and intrasulcular medicament applicator 140 may be releasably coupled to a motorized or other handle, permanently affixed to a motorized or manual handle, coupled to a toothbrush or another oral care brush, or otherwise coupled.

[0043] Referring now to FIG. 16, it is an exemplary image of a foolproof periodontal sulcus brush and intrasulcular medicament applicator 140 in use—with its bristles 154 penetrating into the gingival sulcus 157, after glancing off the tooth 156 at an approximately 45-degree angle, in order to guide their entry into the gingival sulcus.
[0044] Referring now to FIG. 17, a foolproof periodontal sulcus brush and intrasulcular medicament applicator removable head 160 may be shown, which may be coupled to a motorized or manual handle. It is comprised of a base/connector 162, a proximal neck 164, a distal neck 166, and a head 168, with a plurality of bristles 170. The neck 164, 166 portions may offset the head 168 forward of the motorized handle (not depicted), to improve access to the gingival sulci, which are obstructed from being properly accessed and entered, by currently available toothbrushes and other oral care brushes. The head 168 and bristle 170 options are the same as for the foolproof periodontal sulcus brush and intrasulcular medicament applicator 140, previously described.
[0045] Referring now to FIGS. 23-25, a single-headed, multi-row, foolproof periodontal sulcus brush and intrasulcular medicament applicator 180 may be shown. The brush/applicator may be formed out of any of a variety of materials, including, but not limited to, plastics, composites, or any other desired material. The single-headed, multi-row foolproof periodontal sulcus brush and intrasulcular medicament applicator 180 can have a handle 182 with a gripping portion 184, neck portions 186, 188, and a head portion 190. The handle 182 of the single-headed, multi-row, foolproof periodontal sulcus brush and intrasulcular medicament applicator 180 may be substantially flat, square, rectangular, cylindrical, or any combination thereof, and may be solid or hollow. Further, the head 190 and necks 186, 188 may be formed in any shape. For example, the head 190 and necks 186, 188 may have a cylindrical, circular, or rounded shape so as to provide for comfort in use in a mouth. The neck portions 186, 188 may be substantially curved, as desired, and as shown in exemplary FIGS. 18 and 19. And the neck portions 186, 188 may offset the head 190 forward of the handle 182, to improve access to the gingival sulci which are obstructed from being properly accessed and entered, by currently available toothbrushes and other oral care brushes. Further, the head 190 may include a plurality of bristle tufts 192, 194, arranged in multiple vertical rows. The number of vertical rows may range from four to seven, or more. The number of bristle tufts 192, 194, in each vertical row, may be utilized in any number, for example five bristle tufts or three bristle tufts and may be spaced apart substantially equidistantly. It may further be appreciated that the number of bristles tufts in each vertical row, may be from one to ten tufts, as desired and depending, for example, on which species and oral region the single-headed, multi-row, foolproof periodontal sulcus brush and intrasulcular medicament applicator 180 is being used. The spacing may be about 0.5 mm to about 4 mm, for example. The bristles 192, 194 may have any length, for example about 4 mm to about 11 mm or more, as desired. And the length of the bristles 192 in the lateral rows of bristles 192 may be longer than the bristles 194 in the center rows of bristles 194, by 1.0-5.0 mm, or more, in order for the lateral rows of bristles 192 to penetrate the gingival sulci, without interference from, or impedance by, the center rows of bristles 194, and so that the center rows of bristles 194 may brush the chewing surfaces of the teeth, without interference from, or impedance by, the lateral rows of bristles 192. Further, the firmness of the bristles of the central 192 and lateral 194 rows of bristles may vary from one another, due to enamel being the hardest substance, in the body, and gingival tissues being amongst the most delicate. Total length of the head 190 of the single-headed, multi-row, foolproof periodontal sulcus brush and intrasulcular medicament applicator 180 may be about 6 mm to about 30 mm or more, as desired.
