Description

[Technical field]

[0001] The present disclosure is directed to oral hygiene systems. [Background technology]

[0002] Maintaining good oral hygiene can be difficult as it requires more than a semi-annual visit to the dentist for a professional teeth cleaning. Proper daily personal care needs to be implemented to reduce the risk of caries (tooth decay), gingivitis (periodontal disease), halitosis (bad breath) and other oral diseases. Poor oral health has also been shown to increase the risk of or contribute to complications of systemic conditions such as cardiovascular disease, diabetes, pneumonia and pregnancy (mayo clinic). Currently, studies are being conducted to investigate other possible links between periodontal disease and Alzheimer's disease and rheumatoid arthritis. The current market is full of various devices that can help address the needs of the mouth. Manual and electric toothbrushes, floss, gum stimulation devices, and tongue scrapers, along with all kinds of rinses, are placed on the bathroom sink when washing the mouth.

[0003] The purpose and effectiveness of various tooth brushing devices will not be addressed by this discussion beyond saying that there are areas of the mouth that are left soiled by typical tooth brushing methods. Some of these specific areas that require only tooth brushing include, but are not limited to, interdental spaces (flossers), gingival sulci (embrasure brushes), tongue (scrapers), and under the wires of braces (finger-like projections).

[0004] For those with traditional orthodontic devices, brackets, and wires, it is difficult to keep the front of the teeth clean with a toothbrush, under the wires and around the brackets. Gum health often declines as passive stimulation decreases. Additionally, prosthetic devices such as bridges, dentures, and implants create unique cleaning challenges.

[0005] [Patent Document 1] U.S. Patent No. 5,483,982 [Patent Document 2] U.S. Patent No. 8,631,807 [Patent Document 3] US Patent Application Publication No. 2013 / 0000668 [Patent Document 4] U.S. Patent No. 5,483,982 [Patent Document 5] U.S. Patent No. 2,016,597 [Patent Document 6] US Patent Application Publication No. 2006 / 0052805 Summary of the Invention

[0006] The present disclosure is directed to an oral hygiene system. In an example, the incomplete device may include a multi-function handheld oral hygiene system including various headpieces and reusable manual (non-vibrating) or motorized (vibrating) or otherwise powered handles. In an example, the various headpieces may be disposable. In an example, the various headpieces may be attached to various handles to provide a desired combination of cleaning features. The headpieces may include any combination of the following features: suspended dental floss, embrasure brush, tongue scraper, bracket brush, tooth surface scrub, prosthetic sweep. Each of these headpieces may be interchangeable with either a manual or powered vibrating handle and may be intended to be discarded after a certain number of uses and replaced with a new headpiece. The reusable handles may be manual, battery-powered, rechargeable, or plug-in.

[0007] For example, while there are examples of single function devices, e.g., U.S. Patent Nos. 5,233,633, 5,232,625, and 5,366,389, which show flossing, 5,411,663, which show scraping, and 5,411,663, which show stimulating, there has long been a need in the industry to improve and integrate multiple functions into one device or system.

[0008] In an example, an exemplary device of the present disclosure may combine a uniquely designed floss holder with a step-tapered arm that houses finger-like projections that scrub the tooth surfaces and stimulate the gums, along with a traditional tongue scraper headpiece, which may be particularly useful in the care of individuals currently undergoing orthodontic treatment (braces).

[0009] In an example, the headpiece would have a longer, flatter embrasure sweep that has two arms and can pass under a fixed bridge, implant or denture.

[0010] A fully disposable embodiment is also contemplated. In an example, it includes an embrasure brush, floss, and one or more tongue scraper blades. In an example, the handle rides parallel to the fixed head, as opposed to vertical as in other examples. In an example, the head piece may be coupled to a ring-like attachment for the end of a finger or thumb.

[0011] Any one of these embodiments may be scaled down for pediatric use. For clarity of this disclosure, discussion of the details of pediatric use is limited. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Exemplary Devices FIG. 1 illustrates an exemplary oral care device 100. In an example, the oral care device 100 includes a headpiece 102 and a handle portion 104. For example, the headpiece 102 can include a base portion 106 having an arm 108 extending therefrom. In an example, the arm 108 includes a cleaning feature 110, such as a gum sweep. In some examples, the gum sweep can include a tapered shape, for example, to engage with areas of the gums between the teeth and / or adjacent to the teeth. In other examples, the cleaning feature 110 includes multiple cleaning structures. In examples, the cleaning structures can have ribs, protrusions, finger-like structures that can interact with the gums and / or teeth. In examples, the cleaning feature 110 can have a substantially pyramidal or tapered shape. Additionally or alternatively, the pyramidal shape and / or taper can be conformal or asymmetrical. Additionally or alternatively, the headpiece 102 includes a filament 112. In an example, the filament 112 comprises a floss string or ribbon.

[0014] Additionally or alternatively, the cleaning feature 110 may include a gum sweep. In an example, the gum sweep may include a cone or pyramid with a base that rests on the inner surface of the floss head arm, tapering to the point where the floss emerges. The base shape may be circular, oval, square, rectangular, triangular, pentagonal, hexagonal, star-shaped with 3, 4, 5, 6, 7, or 8 points, and the sides of any of these shapes may have concave and / or convex surfaces.

[0015] Additionally or alternatively, the handle portion 104 includes a neckpiece 114. In an example, the neckpiece 114 engages with the headpiece 102 at an interlock 116. In an example, the engagement between the headpiece 102 and the handle portion 104 creates an angle between the handle end of the handle portion 104 and the headpiece 102. In an example, the angle is an obtuse angle when referenced from the arm 108 and the handle of the handle portion 104. In an example, the angle provides improved access to and use of the exemplary oral care device 100 in a user's mouth. In an example, the interlock 116 comprises a lock-and-key style engagement system in which a portion of the headpiece 102 positively engages a portion of the handle portion 104 in a desired configuration. In an example, the desired configuration may include a fixed attachment between the headpiece 102 and the handle portion 104. Additionally or alternatively, the desired configuration may ensure that a desired angle between the headpiece 102 and the handle portion 104 is achieved and / or maintained during use.

[0016] In an example, the angle may be considered a diagonal bend between 1 and 30 degrees. In an example, this allows the neck of the device to be easily oriented parallel to the occlusal surface of the tooth and the floss head arm perpendicular to the occlusal surface.

[0017] In some examples, the headpiece 102 includes a tongue-focused cleaning device. For example, the headpiece 102 may include a tongue scraper 118. In examples, the tongue scraper 118 comprises a ridge or ridges disposed on an edge or side of the base portion 106 distal to the portion of the base portion 106 that engages with the handle portion 104.

[0018] 2A-2C show additional views of an exemplary oral care device. For example, FIG. 2A shows a perspective view of an exemplary oral care device 100. FIG. 2B shows a top view from one side of an exemplary oral care device. In this view, an example of a tongue scraper 118 can be seen. FIG. 2C shows a perspective view of an exemplary device including a view of an end of a handle with a power button. In examples where a power button is included, a vibration feature may be included. In examples where a vibration feature is included, power may be provided by a replaceable or rechargeable power device, such as a battery or capacitor.

[0019] 3A-3E show different views of the exemplary headpiece 102. For example, FIG. 3A shows a top view of the headpiece 102. FIG. 3B shows a side view of the exemplary headpiece 102. FIG. 3C shows a side view of the exemplary headpiece 102 that is perpendicular to the view shown in FIG. 3B. In this view, an example of a portion of the exemplary interlock 116 is shown in the arch 300. FIGS. 3D and 3E show additional views of the headpiece 102 showing additional portions of the exemplary interlock 116. For example, FIGS. 3D and 3E show a first interlock feature 302 and a second interlock feature 304. In the example, the first interlock feature 302 and the second interlock feature 304 securely engage with recessed counterparts located on the handle portion 104. In examples, a combination of the first and second interlocking features 302 , 304 and / or the arch 300 may be used to allow only desired orientations of the headpiece 102 relative to the handle portion 104 .

[0020] FIG. 4 illustrates an exemplary oral care device 400. In an example, the oral care device 400 includes a headpiece 402 and a handle portion 404. For example, the headpiece 402 can include a base portion 406 having an arm 408 extending therefrom. In an example, the arm 408 includes a cleaning feature 410, such as a gum sweep. In some examples, the gum sweep can include a tapered shape, for example, to engage areas of the gums between the teeth and / or adjacent to the teeth. In other examples, the cleaning feature 410 includes multiple cleaning structures. In examples, the cleaning structures can have ribs, protrusions, finger-like structures that can interact with the gums and / or teeth. Additionally or alternatively, the headpiece 402 includes a filament 412. In an example, the filament 412 includes a floss string or floss ribbon.

[0021] Additionally or alternatively, the cleaning features 410 may include bristles. In examples, the bristles may emerge from the arms 408 at an angle between 0 and 45 degrees and may be anywhere from 1 to 5 mm in length.

[0022] Additionally or alternatively, the handle portion 404 includes a neck piece 414. In an example, the neck piece 414 engages with the head piece 402 at an interlock 416. In an example, the engagement between the head piece 402 and the handle portion 404 creates an angle between the handle end of the handle portion 404 and the head piece 402. In an example, the angle is an obtuse angle when referenced from the arm 408 and the handle of the handle portion 404. In an example, the angle provides improved access to and use of the exemplary oral care device 400 in a user's mouth. In an example, the interlock 416 comprises a lock-and-key style engagement system in which a portion of the head piece 402 positively engages a portion of the handle portion 404 in a desired configuration. In an example, the desired configuration may include a fixed attachment between the head piece 402 and the handle portion 404. Additionally or alternatively, the desired configuration may ensure that a desired angle between the head piece 402 and the handle portion 404 is achieved and / or maintained during use.

[0023] In some examples, the headpiece 402 includes a tongue-focused cleaning device. For example, the headpiece 402 may include a tongue scraper 418. In examples, the tongue scraper 418 comprises a ridge or ridges disposed on an edge or side of the base portion 406 distal to the portion of the base portion 406 that engages with the handle portion 404.

[0024] 5A-5C show additional views of the exemplary oral care device 400. For example, FIG. 5A shows a perspective view of the exemplary oral care device 400. FIG. 5B shows a plan view from one side of the exemplary oral care device 400. In this view, an example of a tongue scraper 418 can be seen. FIG. 5C shows a perspective view of the exemplary device including a view of the end of the handle with a power button. In examples where a power button is included, a vibration feature may be included. In examples where a vibration feature is included, power may be provided by a replaceable or rechargeable power device, such as a battery or capacitor.

[0025] 6A-6E show different views of the exemplary headpiece 402. For example, FIG. 6A shows a top view of the headpiece 402. FIG. 6B shows a side view of the exemplary headpiece 402. FIG. 6C shows a side view of the exemplary headpiece 402 that is perpendicular to the view shown in FIG. 3B. In this view, an example of a portion of the exemplary interlock 416 is shown in the arch 600. FIGS. 6D and 6E show additional views of the headpiece 402 showing additional portions of the exemplary interlock 416. For example, FIGS. 6D and 6E show the first interlock feature 602 and the second interlock feature 604. In the example, the first interlock feature 602 and the second interlock feature 604 securely engage with recessed equivalent portions located on the handle portion 404. In examples, a combination of first and second interlocking features 602 and 604 and / or arch 600 may be used to allow only desired orientations of headpiece 402 relative to handle portion 404 .

[0026] 7A-7C show an illustrative example of a handle portion 700. In the example, the handle portion 700 has a positive engagement feature and an angled neck that allows for a desired angle between the handle portion 700 and the headpiece when attached.

[0027] 8A-8C show views of an example handle portion 800. In the example, the handle portion 800 includes positive engagement and orientation features that interact with and orient the headpiece when attached.

[0028] 9A-9C show example views of a portion of a headpiece 900. For example, FIG. 9A shows an example headpiece 900 with example dimensions. It is understood that the dimensions shown are example and represent measurements within a range. In examples, the range for each dimension may include, but is not limited to, + / -1%, + / -2%, + / -5%, + / -10%, + / -50%, + / -100%, + / -200%, or more.

[0029] 9B shows an example of a headpiece 900 interacting in a mouth setting 902 where a first tapered portion of the headpiece 900 engages between a portion of an orthodontic system 904, such as brackets of a brace system connected to teeth 906 creating an area 908 therebetween. In this example, the first tapered portion of the headpiece 900 fits into area 908 allowing for cleaning of the orthodontic system 904 and teeth 906.

[0030] 9C shows an example of a headpiece 900 interacting in a mouth setting 910 where a second tapered portion of the headpiece 900 engages between a portion of an orthodontic system 912 connected to teeth 914 creating an area 916 therebetween. In this example, the second tapered portion of the headpiece 900 fits into the area 916 that allows for cleaning of the orthodontic system 912 and teeth 914.

[0031] 9C and 9B show examples where a second tapered portion of headpiece 900 does not fit into region 908, but does fit into region 916. In some examples, the width, thickness, and length of the tapered portion are configured to fit into and effectively clean regions 908 and 916.

[0032] In various examples, the device may be a multi-function handheld oral hygiene system including various headpieces and reusable manual (non-vibrating) or electrically (vibrating) or otherwise powered handles, as described, for example, with respect to Figs. 1-9C. In examples, the various headpieces may be disposable. In examples, the various headpieces may be attached to various handles to provide a desired combination of cleaning features. The headpieces may include any combination of the following features: suspended dental floss, embrasure brush, tongue scraper, bracket brush, tooth surface scrub, prosthetic sweep. Each of these headpieces may be interchangeable with either a manual or powered vibrating handle and may be intended to be discarded after a certain number of uses and replaced with a new headpiece. The reusable handles may be manual, battery-powered, rechargeable, or plug-in. Example device head and connection

[0033] In various examples, the device may include a handle having a neckpiece that interfaces with each of the various disposable combination headpieces, for example as described with respect to FIGS. 1-9C. In examples, the neckpiece may be uniquely designed and shaped. In examples, the headpiece has a base portion and a pair of spaced jaws that extend perpendicularly from the base to engage the neckpiece of the handle. In examples, the engagement comprises a base for embracing and surrounding the neckpiece in a snap-fit ​​manner when the headpiece is correctly positioned relative to the handle. In examples, the snap-fit ​​may provide an audible indication that the base and neckpiece are properly engaged. In examples, the snap-fit ​​may provide a detectable movement from an unlocked position to a locked position that indicates that the base and neckpiece are properly engaged.

[0034] In an example, the device may use a lock and key style engagement system to ensure that the headpiece is properly oriented with the neck of the handle. In an example, this configuration includes an asymmetric recessed feature found on the neck of the handle with a corresponding protrusion on the inner surface of the base of the headpiece, or vice versa. These interacting features may be of various shapes and sizes. Additionally or alternatively, the interacting features may take the form of text or logos. In an example, the interacting features may take the form of a raised two-dimensional image or relief, for example, showing a raised (or depressed) silhouette of an object (e.g., an animal, a vehicle, a sports object, a face, or a combination thereof, among others). In an example, one or both of the interacting features or the supporting material may be transparent or substantially transparent. In an example, when two interacting features are mated, one or both may be visible or partially visible to the user. A visible interacting feature may be an indication that the neckpiece and base are properly engaged.

[0035] In an example, the headpiece may be held in place by a snap fit, in which an jaw of the headpiece has a snap fit protrusion and the other of the jaws of the headpiece defining a corresponding recess securely engages the headpiece with the snap fit protrusion.

[0036] In examples, the handle portion may be made of wood, plastic, metal, rubber, organic, biodegradable materials, or combinations thereof, among others. There are a variety of finishes, textures, colors, and ergonomic shapes. In examples, the handle portion may be configured with a length and shape that is more suitable for pediatric use. In examples, the handle has a length of 150 mm to 200 mm (184 mm) and a width of 10 mm to 40 mm (20 mm). In examples, the handle portion may be hollow to allow for placement of a motor and power source or solid thickness. In examples, the handle portion may have a diagonal bend of about 160 degrees or a range of 90 to 180, or it may be straight from top to bottom. Without this ergonomic shape, the user would have to open unusually wide to get the gum massager in the correct orientation during use. In examples, the handle portion may be rigid or flexible, with the handle narrowing to fit the neck. In examples, the handle portion may be a single piece such that when the interchangeable head is fixed in place, all of the user's movements are directly translated into a floss / embrasure brush / tongue scraper. In an example, the handle portion may be made up of multiple pieces. An on / off button or switch may be provided on the power handle and on the motor and power source. Exemplary Floss / Stimulation Device

[0037] In various examples, the headpiece provides features to clean the proximal surfaces of the teeth while stimulating the gingival tissue, for example, as described with respect to Figs. 1-9C. In an example, the device includes an anatomically shaped embrasure brush. In an example, the embrasure brush serves multiple purposes. For example, soft texture structures are shaped to contact both tooth surfaces as well as the bridging gum line between them. This interaction may be available to one or both of the outer and inner gingival sulcus, as both arms / jaws may have these structures. Materials used for these structures may include plastic, rubber, silicone, bristles, or brushes. Various examples contemplate various shapes. For example, the structure may include a regular hexagon that is concave on one side. Along each of the three points or spines of the hexagon / pyramid, there may be a row of finger-like projections to increase contact with the oral cavity surface. It may have an overall tapered shape that forms a cone- or pyramid-like profile, where the base is attached to the floss arms and the floss passes through the pyramid and exits at the apex, bridging the two arms.

[0038] In examples, the floss holder headpiece may have a variety of arms and lengths. For example, the length of the arms on the head may range from 15mm to 30mm (16.5mm). The space between the arms may range from 15mm to 30mm (20mm). In examples, the floss holder headpiece may be scaled down to a size more suitable for pediatric users. In examples, the arms may leave the base of the head at a vertical, acute or obtuse angle. In examples, the floss holder headpiece may be made of wood, plastic, metal, rubber, organic, biodegradable materials, or combinations thereof. There are a variety of finishes, textures, colors, and ergonomic shapes.

[0039] In examples, the floss holder headpiece may engage with the handle using various techniques and configurations. For example, engagement may use, among others, snap-fit, magnetic, fixed / solid with head, tongue and groove, slide, screw, strap, fastener, adhesive, or combinations thereof. In examples, floss materials include, among others, nylon, plastic, Teflon / glide, organic fiber, animal hair, or combinations thereof.

[0040] Exemplary anatomical shaped embroidery brush In various examples, the device may include an Emblazer brush, for example, as described with respect to Figs. 1-9C. In an example, the basic shape of the Emblazer brush may be a pyramid in which the base of the pyramid is flat against the extension arm and the other six faces of the pyramid are concave regular hexagons that taper to the apex of the pyramid where the floss emerges. In an example, the structure may be composed of various materials. For example, the core of the sweep may be a simple plastic cone shape with a rubber overlay that forms a more detailed pyramidal structure. Small bristles (rubber or silicone / plastic / nylon / biodegradable material) may line the three acute ridges of the pyramid. In an example, the orientation of the three acute line angles comprising the rows of bristles relative to the user's anatomy is as follows: the top row of bristles rides along the underside of the proximal contact between two teeth, and the other two rows of bristles ride along the junction between the teeth and gum tissue. The two faces of the gum massager that contact the teeth and are not oriented above the gums can be texturized with a series of ribs that can engage the tooth surface to scrape, collect, and remove plaque and debris from the tooth surface. Other shapes can include conical, triangular, cylindrical, star-shaped, gradual taper, step taper. The barbs are also configured differently, evenly spaced, randomly placed, patterned. They vary in size, length, and width. The Emblazer brush can be scaled down in size and / or shape more suitable for pediatric use. Different stiffness or materials can be used to create the same effect.

[0041] Exemplary Scraper As stated in U.S. Patent No. 5,399,993, which is incorporated by reference in its entirety, cleaning the tongue is important. Examples of the present disclosure improve upon currently available techniques and devices. In various examples, the device may include a scraper, for example, as described with respect to FIGS. 1-9C. In an example, when the concave surface of the base of the head engages with the neck of the handle, the exposed convex (or flat) surface of the base may function as a tongue scraping surface with single or multiple blades of reduced or even scalloped edges that terminate in a squeegee-like collecting blade. These blades may bend or arch (or not arch) toward the top of the handle when properly oriented, and travel from anterior to posterior along the tongue surface, functioning as a collecting scoop when repeated over and over.

[0042] In an example, the tongue scraper on the back of the replaceable floss head may have an anatomical and functional shape. Other examples may be less anatomical and functional. An example tongue scraper may be convex in both the xy and yz axes. This allows it to clean the center of the tongue (and all other parts) and also allows the scraped debris to be contained in the curved end. In an example, the first of the three silicone / rubber / plastic blades of the tongue scraper with multiple shades acts like a comb or rake in lifting and breaking up the debris, while the second blade with its scalloped edge continues to lift and collect the debris. The third straight edge blade squeegees and removes all bacteria and debris. Other examples use a single blade or multiple blades in other combinations. In an example, various heights, lengths, or materials of the blades may have a similar effect. Vibration may increase its effectiveness, encouraging repeating this action over the entire area of ​​the top surface of the tongue.

[0043] Exemplary Orthodontic Devices There are unique cleaning challenges faced by people who require temporary orthodontic treatment. However, while some specialized orthodontic floss holders are available, they fail to provide significant gum stimulation that is often diminished by the placement of wires and brackets used during the months or years of straightening the teeth. The brackets and wires also add further challenges when attempting to clean the front of the teeth by traditional tooth brushing methods. In various examples, devices can be tailored to address these issues, for example as described with respect to Figs. 1-9C. In an example, an orthodontic style disposable head can incorporate a set of thinner floss holding arms, where an embrasure brush can be replaced with the addition of a tooth scrubbing surface on the inside of the arms. These arms may feature a stepped taper to accommodate the different bracket spacing found on the upper and lower teeth. The side edges of these arms may be lined with additional finger-like projections intended to stimulate the gums and remove debris from the sides of the brackets.

[0044] Alternative floss holder designs, e.g., orthodontic flossers, may have arms of different shapes to allow children and adults with braces to easily floss with the brackets and wires in place. The extension arms on the flosser are sufficiently tapered front to back and side to side to allow the extension arms to pass between the orthodontic brackets on adjacent teeth and under the orthodontic wires. In one example, the inner surface of the extension arms may have silicone / rubber ribs that extend and clean the front of the teeth under the wires that are often missed with regular brushing and flossing. Also, the outer edge of the tip of the extension arm may have silicone / rubber bristles (3.6) that stimulate the gum tissue adjacent to the teeth that often becomes inflamed due to lack of stimulation when people are in braces, brush the junction between the bracket and the tooth where a white demineralized ring often occurs on the teeth around the bracket, and clean and clean any food or debris that may collect on the sides of the bracket.

[0045] One aspect of cleaning spaces between brackets and under wires that has not been fully addressed by other orthodontic flossers is the fact that the spaces between brackets vary greatly, primarily depending on the size and width of the teeth themselves. The lower front teeth, for example, are the thinnest teeth, but they are also very short. So if the extension arm is thin enough to fit between the sides of the lower front teeth to clean, it can also easily pass between the brackets of the upper front teeth, but that space may be so wide that the bristles along the end of the extension arm cannot reach the sides of the orthodontic brackets and clean them properly. In an example, an orthodontic flosser may include a stepped design where the first few millimeters of the tip of the extension arm are thin enough to pass between small spaces, such as the lower front teeth, but then the extension arm becomes wider to move the bristles wider to clean the larger spaces between the larger teeth, such as the upper front teeth. These upper front teeth are also taller, allowing the extension arm to move further into the space, which allows the wider portion of the extension arm to move into the space and brush away debris. The arms can also be a gradual taper, as opposed to a step or uniform width from base to tip.

[0046] Example Emblazer Sweep In various examples, for example, as described with respect to Figures 1-9C, another configuration contemplated by the present disclosure includes an embrasure sweep. For example, the embrasure sweep may include a flossless head with a relatively long, thinner sweep configured to reach slightly beyond the midpoint under the bridge or denture / implant to remove debris, clean surfaces, and stimulate gum tissue.
