FIELD OF THE INVENTION

[0001] The present application relates to oral devices including interdental anchors.

BACKGROUND OF THE INVENTION

[0002] Certain medical procedures require the ability for health care personnel to engage and hold a medical device in place. For example, intubation such as endotracheal intubation, intubation with a transoral laryngeal mask, or nasopharyngeal intubation are all common procedures that require securely fastening a medical device into position.

[0003] A common problem associated with tubing is that it can be difficult to keep in place when connected to the patient or otherwise used during a procedure. Proper positioning of tubing is often important, and inadvertent dislodgment can be hazardous or even life-threatening (e.g. inadvertent dislodgement of an endotracheal tube).

[0004] Attempts have been made to address the above problem. The conventional technique used to fasten medical devices to patients involves the use of adhesive taping or bandages. This approach has its own shortcomings. Therefore, in the region of the head and neck, tubing is sometimes secured by placing a suture through the oral buccal sulcus mucosa/submucosa and then wrapping it around and tieing it to the perioral tube. In other instances, a circumdental wire is first passed around a tooth, then wrapped around the tube and twisted snugly. Alternatively, another method involves the use of straps, with or without a fastening cuff, that encircle the head or neck of the patient and attach to a tube.

[0005] Other medical procedures require the jaw and/or teeth to be generally held in place, e.g., bringing the maxillary and mandibular dentition into approximation either firmly for fracture repair procedures, or more loosely when trying to prevent mandibular retrusion leading to certain forms of sleep apnea. The present approach to placing the maxillary and mandibular dentition into firm occlusal position for surgical indications is with the use of dental arch bars and circumdental wires, or with the use of bone-anchored screws with wires or elastic bands. For individuals with sleep apnea arising from mandibular retrusion, the use of customized or non-customized tooth-borne splints, or the use of continuous positive airway pressure mask/pump are treatment options. [0006] However, these and other attempted solutions have cost and morbidity implications, and risks of discomfort and injury to the patient and health care worker.

DETAILED DESCRIPTION

[0044] The present application relates to oral devices comprising interdental anchors that can be flossed between adjacent teeth of a mammalian patient (e.g. human).

[0045] Fig. 1A is a perspective view of an oral device 100 according to one or more aspects of the disclosure. Fig. IB is a plan view of an oral device 100 according to one or more aspects of the disclosure. [0046] The oral device 100 can be made of any type of material capable of elastically deforming and subsequently returning to its original size and shape, such as a polymer. In one example, the polymer can be silicone, such as Silicon Shore 60 A, 70A, or 80A. In another example, the device may incorporate portions that are less compliant such as any of a variety of plastic materials. The oral device 100 can be integrally formed such that it can be molded or cut from a sheet as a single unitary piece (and can have a uniform height hi as shown in Fig. 1 A). In other examples, the oral device 100 can have one or more

interconnected parts that can be separately formed.

[0047] As shown, the overall body of the oral device 100 can include an interdental anchor portion 110, a securing portion 120, and the body of the oral device 100 can define a hole 130 configured to receive a portion of the securing portion 120.

[0048] The interdental anchor portion 110 can include an interior portion 112, e.g., a lingual or palatal portion. As used herein, the terms lingual or palatal refer to a surface of a tooth that is closest or next to your tongue. For the upper teeth, this is called the palatal surface. For the lower teeth, this is called the lingual surface. Further, teeth can refer to natural teeth, dentures, teeth of a human patient, or teeth any of kind of animal patient.

[0049] The interior portion 112 can have a first width wi that can be any width appropriate for the size of a mouth of the mammalian patient. The width wi can have a range of 6-10mm, and in one example can have be approximately 8 mm in width, e.g., 8 mm +/- 0.5 mm.

[0050] The interdental anchor portion 110 can also include an anchor portion 114

(e.g., flossing portion) configured to reside in an interdental gap of the patient. As used herein, "interdental gap" or "interdental space" is used interchangeably with "gingival interdental space" and "gingival dental embrasure," with all terms referring to a space between any two adjacent teeth. The anchor portion 114 can have a width W2 in the range of lmm to 2mm. In one example, the width W2 can be approximately 1.6 mm, e.g., 1.6 mm +/ 0.15 mm. The anchor portion 114 can have a length i _\ in the range of 0.5-5 mm. In one example, the length i _\ can be approximately 3 mm, e.g., 3mm +/- 2.5 mm. In addition to the ranges set forth above, the length and width of the anchor portion 140 can vary beyond the above-identified ranges depending on a number of factors, such as the size of the mouth, the size of the tooth, the portion of the mouth in which the oral device 100 will be installed (e.g., incisor, canine, premolar, molar, etc.), variations to the tooth or mouth that may cause interdental spacings vary from other interdental spacings in the same mouth, such as overlapping teeth, or injury, or any other variation that can cause the interdental spacing to be larger or smaller than average.

[0051] The interdental anchor portion 110 can also include exterior portion 116, (e.g., a facial portion). As used herein, the term facial can be considered an umbrella term for both buccal and labial. Buccal and labial refer to the tooth surface that faces the outside of a mammal's mouth. For teeth closer to the rear of the mammal's mouth, the tooth surface that is closest or next to the check is called the buccal surface. For teeth that are closer to the front of the mouth, the surface that is closer to the lips is called the labial surface. The exterior portion 116 can have a width substantially similar to the width of the interior portion 112.

[0052] The interdental anchor portion 110 can also include an interior transition portion 112a and an exterior transition portion 116a. The interior transition portion 112a comprises a portion of varying with between a width of the interior portion 112 and the width of the anchor portion 114. Similarly, the exterior transition portion 116a comprises a portion of varying width between the exterior portion 116 and the anchor portion 112. In the example of Figs. 1 A and IB, the interior and exterior transition portions 112a, 116a comprise a linear transition, but other geometric shapes, such as curved or otherwise non-linear transitions are possible.

[0053] The body of the oral device can define a hole 130, as mentioned above, to receive a securing portion 120. The securing portion 120 can include one or more protrusions 122 (e.g., notches) configured to pass through and/or engage with the hole 130. In this regard, the hole 130 can have a width W3 in the range of 4-7 mm, and in one example can have a width of approximately 6.3 mm, e.g., 6.3mm +/- 0.1 mm.

[0054] The protrusions 122 can have a width W4 in the range of 6-8mm, depending on the size of the hole 130. In one example, the width of the protrusion 122 can be

approximately 7.0mm, e.g., 7.0+/-0.1mm. The sizes of the hole 130 and protrusions 122 can be highly variable, and the relative difference in size can be in the range of 0.5 to 1 mm in order to ensure that the protrusions 122 fit through the hole 130 (by elastic deformation), but are not easily returned back through the hole 130 in order to secure a medical device within the securing portion 120. The protrusions 122 can include adjacent planarized surfaces 122a that can assist in preventing the protrusions 122 from returning back through the hole 130.

[0055] The length of the securing portion 120, number of protrusions 122, and the pitch spacing therebetween can be highly variable depending on a number of factors, such as the size and shape of the medical device to be secured, the flexibility of the silicone used for the oral device 100, the size and/or shape of the patient's mouth, etc.

[0056] As depicted, the interdental anchor portion 110 can be formed at a

substantially right angle with respect to the securing portion 120, such that the oral device generally forms an "L" shape. In other examples, the portions 110 and 120 can form acute or obtuse angles with respect to one another.

[0057] Fig. 2 depicts a jaw of a patient with the oral device 100 installed. As shown, the interdental anchor portion 110 is flossed between adjacent teeth T and is secured within the interdental space. Once secured, the securing portion 120 can be wrapped around the medical device 210 (e.g. a tube) as depicted by arrow A and subsequently inserted through the hole 130 until the securing portion 120 fits snugly and securely around the medical device 210. The medical device 210 can be any type of medical device, such as a tube for breathing, a cable for an endoscopic camera, or any other type of medical device.

[0058] To install the oral device 100, the medical professional can provide a relative opposing force between the interior and exterior portions 112, 116 so as to elastically deform at least the anchor portion 114. The elastic deformation can include at least one or more of the following deformations: increase in length of the anchor portion 114; decrease in width W2 of the anchor portion 114; and/or decrease in height hi of the anchor portion 114. This can be accomplished either manually or with an instrument.

[0059] In the example depicted, the anchor portion 114 has a generally rectangular cross-section. It is expressly contemplated that the anchor portion 114 can have other geometric configurations and that the elastic deformation can affect the dimensions of those configurations accordingly.

[0060] In the manual example, a medical professional may grasp the oral device 100 with one hand on the interior portion 112 and one hand on the exterior portion 116 (or near the hole 130). Once gripped, the medical professional may pull the two portions 112, 116 in opposing directions relative to one another in order to provide the above-mentioned elastic deformation. Once the desired amount of deformation is achieved, the anchor portion 114 can be inserted into the interdental space between two adjacent teeth. This can be achieved based on the decrease in width w ₂ , the overall elasticity of the oral device 100, and the fact that teeth are in close proximity at the level of the cusp, but diverge at the level of adjacent dental cervix. That is, the crown of a tooth has a "waist" that results in the presence of the above-mentioned interdental gap. [0061] Once the anchor portion 114 is positioned correctly within the interdental space, the professional can release the opposing force to allow the oral device 100 to elastically deform back to its original state (e.g., back to and w ₂ ). Having returned to its original state, the anchor portion 1 14 now engages with the adjacent teeth in the interdental space and the gums above or below by a friction fit and is held snugly and securely therewithin.

[0062] Once the interdental anchor portion 1 10 is secured, the securing portion 120 can now be engaged with the medical device. In the example of a tube, the securing portion 120 can be wrapped around to at least partially encircle the medical device. While doing so, the medical professional can feed one or more of the protrusions 122 through the hole 130. The number of protrusions 122 to be fed through the hole 130 depends on the length of the securing portion 120 as well as the overall size (or caliber) of the medical device to be secured. The medical professional can begin by feeding the distal portion 124 of the securing portion 120 through the hole 130. Since the distal portion 124 has no protrusions 122, this section is easily fed through the hole 130 and can be gripped on the other side once fed through. Once the first protrusion 122 approaches the hole 130, the distal portion 124 can be pulled with sufficient force to elastically deform the protrusion 122 (e.g., reduce the width w4) such that the protrusion 122 can be fed through the hole 130. Once the protrusion 122 is fed through the hole 130 and reaches the other side, the protrusion 122 returns to is original state and will now require a similar force to be removed the hole 130. Absent such force, the securing portion 120 can be formed into in a closed loop that secures the medical device in place relative to the patient's mouth. This process can be repeated until the desired length of securing portion is encircled around the medical device.

[0063] To remove the securing portion 120 from engagement with the hole 130, the securing portion 120 can be pulled out of the hole 130 with sufficient force to again elastically deform the protrusions 122, allowing them to return back through the hole 130. This can be repeated until all protrusions 122 are removed from the hole 130 and the medical device can be removed.

[0064] To remove the interdental anchor portion 1 10, an opposing force can be applied with respect to the portions 112 and 1 16 to elastically deform the anchor portion 114 to a reduced width such that it can be disengaged with from the interdental space.

[0065] Fig. 3 depicts an oral device 300 according to another aspect of the disclosure.

In this example, the interdental anchor portion 110 can be substantially similar to the example set forth in Figs. 1A-B. In this example, however, the securing portion 220 can define a plurality of holes 222 and the oral device 300 can include a post 330. The post 330 can have a dimension (e.g., diameter) greater than a dimension (e.g., diameter) of the holes 322 such that at least one of the holes 322 can be pressed onto the post and elastically deformed to engage therewith. Once engaged, the securing portion 320 can securing a medical device therein similar to the example set forth above.

[0066] Fig. 4 depicts the oral device of Fig. 3 in operation. As shown, the interdental portion 110 is engaged in the interdental space between two adjacent teeth (as is described above with respect to Fig. 2). The securing portion 320 can wrap around or encircle the medical device 210 (e.g., tube) so as to secure the medical device 210 relative to the mouth of the patient. The securing portion 320 can be wrapped around the medical device such that one of the holes 322 engages with the post 320. As shown, the post 330 has a thick section 332a and a thinner section 332b, with the thick section have a greater diameter (or any other dimension) than the thinner section. One of the holes 322 can plastically deform to fit around the thick section and be secured on the thin portion, thereby securing the medical device in place.

[0067] Fig. 5A is a perspective view an oral device according to another aspect of the disclosure. Fig. 5B is a side view of the oral device of Fig. 5 A. Fig. 5C is a cross section of the oral device of Figs. 5A-B along the line A- A. Fig. 6 is a side view of the oral device of Figs. 5A-C with a ruler (cm) for scale.

[0068] The oral device 500 can be made of any type of material capable of elastically deforming and subsequently returning to its original size and shape, such as a polymer. In one example, the polymer can be silicone, such as Silicon Shore 60 A, 70A, or 80A. The oral device can be integrally formed such that it can be molded or cut from a sheet as a single unitary piece or it can have one or more interconnected parts that can be separately formed.

[0069] As shown, the oral device 500 includes a cap 510, an anchor portion 520 (e.g., flossing portion), and a base 530. A top surface of the cap 510 can be a substantially spherical cap (e.g., a portion of a sphere cut off by a plane) having a height h ₂ in the range of l -2mm and a width w _¾ in the range of 2-4 mm when viewed from the side. The cap 510 can have a radius of curvature thereby defining a "mushroom" shape to the cap.

[0070] The flossing or anchor portion 520 can be substantially cylindrical such that it has a circular cross section and a radius in the range of 1-2 mm. In one example, the radius can be approximately 1.6mm, e.g., 1.6mm +/- 0.5mm. In other examples, the cross section of the anchor portion can be substantially elliptical such that it has a major axis that is greater in dimension than a minor axis.

[0071] The base 530 can have a width W6 in the rage of 2-3 mm that can be less than or equal to the width of the cap and can have a planar surface 532. The base can include a transition portion 534 that transitions between the planar surface 532 and the anchor portion 520.

[0072] As shown in Fig. 5C, the cap can define a radial cavity 514 defined between the distal portion 512 of the cap and the anchor portion 520. The radial cavity 514 is at least partially vertically recessed within the cap 510 such that at least a portion of the radial cavity extends above the distal portion 512 with respect to the base 530. The radial cavity can itself be curved such that it defines a radius of curvature.

[0073] The oral device 500 can be installed manually by a medical professional, can be installed with an instrument, or can include attachment features (as will be described in detail below). During manual installation, a medical professional may providing an opposing force relative to the cap and the base, thereby elastically deforming the anchoring portion 520. The elastic deformation can include a decrease in radius and diameter (in the example of a circular cross section). In the example of the elliptical cross section, the major axis diameter may increase while the minor axis may increase (or vice versa). This elastic deformation allows the anchoring portion to be inserted into the interdental space of a patient. In the elliptical example, the anchor portion 520 can be inserted with the major axis positioned vertically in the interdental space and subsequently rotated such that the major axis is disposed horizontally with respect to adjacent teeth.

[0074] Once positioned in the interdental space, the opposing force can be removed and the oral device 500 can return to its original state, with the anchor portion 520 providing a friction fit in the interdental space and thereby securing the oral device between two teeth in the mouth. Once returned to its original state, the base 530 can fit snugly against the lingual or palatal surfaces of the adj acent teeth while the distal portion 512 of the cap can fit snugly against the facial portion of the adjacent teeth. This configuration results in the cavity 514 being formed and at least partially or completely enclosed between the distal portion and the facial portion of the tooth. Once engaged, a portion of an elastic band (not shown) can be engaged with the cavity. This process can be repeated over a plurality of teeth, such that the patient's mouth can include a plurality of oral devices installed therein and the oral devices can be secured to one another by elastic bands, thereby securing the teeth, mouth, and/or j aw in place.

[0075] For example, oral devices can be placed in adjacent interdental gaps on the lower teeth and/or can be placed on interdental spaces on the lower and upper jaws. Elastic bands could first be applied to the anchors on the lower jaw (horizontally) on either the lingual/palatal side and/or the labial side, before placing the maxillomandibular bands (vertically) in order to prevent anchor dislodgment.

[0076] Although the examples of Fig. 5A-C depict an oral device 500 with a cap 510 and a base 530, another example of the present application includes an oral device having a second cap instead of the base 530 (e.g., a double-capped oral device, as depicted in Fig. 8).

[0077] Fig. 7A is a perspective view an oral device according to another aspect of the disclosure. Fig. 7B is a side view of the oral device of Fig. 7 A. Fig. 7C is a top view of the oral device of Figs. 7A-B.

[0078] The anchor portion 520 and base portion 530 are substantially similar to the example set forth in Figs. 5A-C. In this example, the cap 710 defines a cutout 712. As shown in Figs. 7B-C, the cutout 712 can be triangular (when viewed from above) and can extend between the distal portion 714 and a central axis C of the oral device 700. An angle formed by the cutout can be any angle in the range of 45-90 degrees, and in one example defines an angle of 60 degrees.

[0079] During installation, the cutout 712 provides the medical professional an entry point for inserting the elastic band into the cavity.

[0080] Fig. 8 depicts a double-capped oral device 800 according to one or more aspects of the disclosure. In this example, the first cap 810 and second cap 820 can be secured on interior and exterior portions of the teeth and elastic bands can be installed on either side of the tooth, with the anchor portion 830 being flossed between adjacent teeth. Each of the caps 810 and 820 can define cavities 812 and 822 (not shown) for receiving an elastic band.

[0081] In another example, the double-capped device can include a longer anchor portion that can be engaged with two adjacent interdental spaces simultaneously such that both caps face outward. The 'double-capped' anchor would therefore have an identical mushroom cap on both ends and the two caps would face labially out from two adjacent gingival embrasures. This configuration can add stability and prevent dislodgment during the tight fixation of upper-to-lower jaw with orthodontic elastic bands. [0082] Fig. 9 is a perspective view of an oral device according to another aspect of the disclosure. In this example, oral device includes two caps 910 and 930 and an anchor portion 920. In this example, the cap 910 defines a cutout portion 914 while the cap 930 is identical to the cap 510.

[0083] Fig. 10A is a front view of a patient with a plurality of oral devices 1010-1040 installed between teeth T. As shown, the caps of the oral devices 1010-1040 can face outward to allow for installation of elastic bands (not shown). For example, an elastic band can be connected from band 1010 to band 1020 and another from band 1010 to band 1040. Any combination of elastic band connections is contemplated based on the desired configuration of oral devices.

[0084] Figs. 10B-D depict several examples of elastic band arrangements according to one more examples of the disclosure. A number of elastic bands 1050 can be placed ranging from a single one centrally, one on either side, to many placed bilaterally, depending on the requirements. During repair of a mandibular and/or maxillary fracture, the rubber bands may be placed in a more upright (vertical) orientation in order to encourage a firm occlusal position ("maxillomandibular fixation = MMF"), as shown in Fig. 10B.

[0085] In other circumstances, the objective may be to shift the mandible forward (for example, in preventing mandibular retrusion during sleep to prevent sleep apnea) or the maxilla posteriorly (ex. post-operatively in a situation where the occlusion requires some fine adjustment). This can be achieved by placing the elastic bands on the anchors in an oblique vector (as generally indicated by the arrows) as demonstrated in Figs I OC and 10D.

[0086] Fig. 11 is a schematic diagram of an oral device with attachment features according to another aspect of the disclosure. As shown, the oral device 1100 can include end caps and an anchor portion 1 120. In order to facilitate elastic deformation, removable attachment features 1150 can be removably, semi -permanently, or permanently attached to the end caps 1 1 10 and 1 130.

[0087] Fig. 12 is a schematic diagram of an oral device with attachment features according to another aspect of the disclosure. As shown, the oral device 1200 can include end caps and an anchor portion 1220. In order to facilitate elastic deformation, removable attachment features 1250 can be removably, send-permanently, or permanently attached to the end caps 1210 and 1230. One or both of the caps 1210 and/or 1230 can define the radial cavity (as described above with respect to Fig. 5 and elements 512 and 514) defined between the distal portions 1212 and/or 1232 of the caps and the anchor portion 1220. [0088] Fig. 13 depicts various stages of installation of the oral device of Figs. 11 or

12 according to one or more aspects of the disclosure. As shown, the oral device 1300 can include a pair of caps and 1310, 1330 and an anchor portion 1320 to be flossed between adjacent teeth T. The oral device 1300 can also include attachment features 1350 with tapered ends 1350a for use during installation. Optionally, a washer 1360 may also be provided, as will be described in detail below. The washer can be formed of a polymer similar to the oral device above, e.g., medical silicone, high durometer, firm but gentle against the teeth. In another example, the washer can be fabricated out of silicone or some other compatible elastic material. In one particular example, the washer can have a stainless steel ring along an outer surface so that instead of using elastic bands (as shown in Figs. 10B- D), fine surgical wire (26G or 25G) could be used to achieve MMF as is commonly done with conventional stainless steel arch bars and wires.

[0089] The washer 1360 may be slipped over the tapered end 1350a of the attachment feature 1350 toward the oral device 1300 until it is adjacent to a surface of the cap 1310 facing away from the anchor portion 1320. A medical professional may then grip the attachment features 1350 (or the tapered ends 1350a) and provide an opposing force to cause elastic deformation of the anchor portion 1320, as shown at stage 4. Once the deformed anchor portion is flossed between adjacent teeth, the washer 1360 may be advanced over the cap 1310 such that the anchor portion 1320 is disposed within a central hole 1360a defined in the washer 1360. The medical professional may then release the opposing force, allowing the anchor portion to deform and the caps 1310, 1330 and washer 1360 to be secured. In this example, the washer can be secured against the labial or inside surface of the teeth. The attachment features 1350 can be removed, for example, by cutting, perforation, or any other such removal method. Once removed, elastic bands may be secured to the oral device 1300 as described above.

[0090] The foregoing has been a detailed description of illustrative embodiments of the invention.
