DETAILED DESCRIPTION

[0029] In some aspects, the CTHBB or bite blocker is made of a thermoplastic compound. The device can be fitted to an individual by heating the device in hot water, thereby creating a malleable state. The device may then be fitted to the non-affected site (the side of the mouth that is not affected by the abscessed tooth). As the compound cools, the form becomes permanent. This process takes a matter of minutes to accomplish, and can be performed by either the individual or a dental technician.

[0030] The CTHBB may be placed in either the right side of the mouth, or a mirror image CTHBB can be placed in the left side of the mouth. If the device is placed in the right side of the mouth, the upper and lower teeth on the left side of the mouth are blocked from occlusion (or contact), thereby preventing the onset of pain associated with occlusion and the resultant contact pressure on an affected tooth. Hence, a right CTHBB prevents occlusion of the left dentition, and a left CTHBB prevents occlusion of the right dentition.

[0031] The CTHBB, by virtue of having been customized to the dentition of the patient, is seated firmly in place and is not subject to movement in the mouth. In the event the CTHBB, following custom thermoplastic fitting, is not firmly seated over the dentition, a denture adhesive cream, for example, may be applied to the inner channel of the CTHBB prior to seating the device over the teeth. This will provide added assurance that the device will not be subject to movement in the mouth. Various other or alternative adhesives may also be used in order to provide additional security. The adhesive may be applied for example, after the CTHBB has been formed to the user's mouth, or without custom forming.

[0032] In additional embodiments, the CTHBB may be formed based on a 3D scan of a user's mouth. The user's mouth can be scanned, resulting in a 3-dimensional model of the area to be protected by the CTHBB. Using the 3D model, a custom CTHBB may be constructed using various molding, CNC, pressure casting, 3D printing or other techniques. In such an embodiment, non-thermoplastic materials can be used, since custom forming is accomplished in the design and manufacturing process itself.

[0033] In some instances, the CTHBB can provide an emergency, short term strategy that prevents occlusion of the affected dentition until which time an endodontist or dentist can perform a root canal, or an extraction, or until which time the patient completes a course of antibiotic therapy in an attempt to resolve any infection.

[0034] The CTHBB can be worn during the day, or during the evening to prevent occlusion of the upper and lower teeth on the contra-lateral side of the mouth (where the affected tooth resides). The CTHBB may provide the patient a method of preventing occlusion of the affected teeth during the sleeping hours thereby providing the patient the opportunity to gain restful restorative sleep.

[0035] By virtue of the device preventing occlusion of the affected tooth, or teeth, thereby avoiding the painful stimuli of pressure on the affected tooth, the patient may be able to consume lower doses of narcotics, or may be able to avoid the consumption of narcotics all together (thereby lowering, or eliminating the potential adverse effects of consuming narcotics or opiates).

[0036] In some cases, the CTHBB or bite block device (e.g., the layer formed between the teeth), may be approximately 3-10 mm thick at its far anterior position, and 3-12 mm thick at it's far posterior position. When installed into the mouth of a patient, there may be approximately 2-10 mm of clearance between the upper and lower teeth. The device may be designed to target a clearance between the upper and lower dentition of between 3 to 9 mm, with 5-7 mm to be optimally comfortable, and to assure that the molars in the rear are not making contact. Depending on the size of a patient's teeth, mouth, jaw, etc., the above dimensions may vary anywhere between 5, 10, 20, or even 50 percent.

[0037] In additional embodiments, the posterior portion of the CTHBB may be raised by a few mm to approximate the height of the anterior portion.

[0038] In some aspects, the amount of material used to produce the pre-formed mold (e.g., thickness) may be, at least in part, selected to yield a different height of sidewall formed when the patient bites down on the pre-formed mold. This may be particularly useful for patients having smaller sized teeth, mouth, or jaw.

[0039] FIG. 1A depicts a front perspective view of an embodiment 100A of the present invention. As depicted the bite blocker includes an anterior wall 103 and a posterior wall 104. These walls are separated and form channel 105. Together, the space formed by the interior portions of the anterior wall 103, the posterior wall 104 and the channel 105 accepts the user's teeth and gums when installed. For example, the upper ridge of the anterior wall, when the bite block is installed, is located toward the upper portion of the user's outer facing gums, near the base of the upper lip. The overall height of the walls 103 and 104 may depend on the model or size offered. For example, an adult version may have walls of approximately 12-18 mm, whereas a model for younger or smaller users may have a range from 10-16 mm. In addition, the height of walls 103 and 104 relative to one another may change depending on the embodiment, for example, 100A depicts the walls of equal or nearly equal height. A taller posterior wall 104, for example, may help improve stability of the device. This is helpful where the user intends to wear the device while sleeping, the taller posterior wall 104 preventing the blocker from shifting while the user is unconscious.

[0040] The overall shape and contour of the channel 105 as well as the shape and contour of the walls 103 and 104 where they meet channel 105 can be augmented by the user during the thermo-forming process. The same is true of the underside of the bite block, 106. In some embodiments, including the one depicted in FIG. 1A, the underside 106 may include pre-molded portion to better form to the user's teeth. Such as, in the depicted example, the underside 106 is molded to better form to the user's lower teeth. These ridges in lower portion 106 can help increase the contact area of the device, improving comfort and stability. The contour and shape of the lower portion 106 can also be altered through the thermo-forming process, including where ridges are pre-molded.

[0041] FIG. 1B depicts an alternative embodiment 100B. This embodiment is very similar to 100A, except that here, the posterior wall 104b is much shorter compared to anterior wall 103. The height of the posterior wall 104b may be anywhere between that depicted in embodiments 100B and 100A, the depicted embodiments should not be seen as limiting. The shorter posterior wall 104b may be more comfortable for some users, especially those who do not intend on wearing the blocker at night, or, alternatively, for those who intend to use an alternative means of increasing the bite blocker's security, for example, denture adhesive cream applied in channel 105.

[0042] FIGS. 2A and 2B depicts a rear perspective view of embodiments 100A and 100B, here labeled as 200A and 200B. As depicted, the channel 205 may be shaped to progressively widen as the channel extends toward the back of the mouth in order to accommodate the wider tooth profiles. The walls, 203 and 204 may also progressively taper, eventually meeting the channel 205.

[0043] FIG. 3 provides a top down perspective of an embodiment of the present invention. As depicted, the upper portion of either wall 303 or 304 may be rounded, and may increase or decrease in thickness at various points. For example, additional thickness in the corner of the mouth may provide additional security and comfort. This perspective, again, shows where the profile of the channel 305 changes along its length to accommodate the change in tooth shape and profile.

[0044] FIG. 4 provides a bottom up perspective of an embodiment of the present invention. As depicted, the bottom 406, may include ridges to accommodate the teeth opposite the channel. Bottom 406 may be constructed of different polymers in order to better accept the teeth. For example, the inner portion, as depicted, may be constructed of a softer more thermos-responsive material, while the perimeter portion may be more firm, providing stability. In various embodiments, the anterior wall, 403, may extend beyond the bottom 406. This can provide additional support and comfort, resting against the inner portion of the user's lip.

[0045] FIG. 5 depicts a rearward view of a bite block device. From this viewpoint, the thickness of the point from the channel 505 to the bottom 506 is demonstrable. In the depicted embodiment bite block device (e.g., the layer formed between the teeth) may be approximately 7.6 mm thick at its far anterior position, and 8.5 mm thick at it's far posterior position. When installed into the mouth of a patient, there may be approximately 6 mm of clearance between the upper and lower teeth. The device may be designed to target a clearance between the upper and lower dentition of between 5 to 7 mm to be optimally comfortable, and to assure that the molars in the rear are not making contact. It should be appreciated that the above dimensions are only given by way of example. Depending on the size of a patient's teeth, mouth, jaw, etc., the above dimensions may vary anywhere between 5, 10, 20, or even 50 percent. In some cases, different size bite blocker molds (pre-formed) may be designed for different patients to accommodate different teeth and mouth or jaw sizes, based on age, or other metric.

[0046] FIG. 6 depicts a side view of a right sided embodiment of the present invention. In the depicted embodiment, the anterior wall 603 is constructed of at least two different polymers, 603b and 603a. In such an embodiment, the outer portion, 603a, may be constructed from a stiffer material to provide increased rigidity to the device in order to ensure it maintains proper shape and alignment when in use. Meanwhile, the inner-portion 603b may be constructed of a softer, more pliable material in order to allow it to better conform to the user's teeth and gums. More specifically, in various embodiments, bite block device may be made from a variety of materials, including one or more thermoplastic compounds, such as found in commercially available sports mouth guards. In multilayer embodiments, such as the one depicted, the outer layer (e.g., corresponding to the part of the bite blocker that is positioned on the outside of the patient's teeth) may consist of a solid medical grade, FDA approved Polypropylene that adds structural support and strength. The inner layer (e.g., corresponding to the part of the bite blocker that is positioned in between/on the inside of the patient's teeth) may consist of any thermoplastic material approved by the Food and Drug Administration (FDA), that renders the bite blocker it's characteristic “boil and bite” feature. The most common thermoplastic material for this type of application is ethylene-vinyl acetate (EVA), but other materials may work as well and will be known to those in the art. The “boil and bite” characteristic is derived from the thermoplastic inner lining that softens when applied to hot water, then adapted to the individual's mouth by biting down on it and holding for typically 30 to 45 seconds. The use of a thermoplastic compound provides a self-adapting quality allowing the upper teeth to be seated more comfortably into the device by generating a custom mold. It also secures the teeth into the device much more adequately than the alternative of using a rigid, non-thermoplastic compound in the channel of the bite blocker.

[0047] While not depicted in this particular embodiment, the posterior wall 604 may also be constructed of one or more materials much in the same manner and for the same reasons as the anterior wall 603.

[0048] FIG. 7 depicts the side view of an embodiment of the present invention employing at least a second material for the outer portion of the anterior wall 703. As depicted, the preferably stiffer outer material 703a may extend significantly rearward and may cover some or the entire anterior wall. As depicted, in some embodiments the stiffer portion 703a may end prior to the upper edge. Where this is the case, the second material, preferably a softer material is used at the points of contact with the gums and teeth. The outer portion may be stylized, or formed with additional designs or arrangements to increase stiffness further or to be more pleasing to the eye. A third or more material may also be used along a portion of the outer wall 703 in order to provide additional stiffness. For example, a third material may be placed in a bracing fashion longitudinally along the anterior wall.

[0049] FIG. 8 depicts an embodiment of the present invention as worn by a user. Where a user is suffering from a tooth ailment, the user's pain may be pacified by restricting jaw movement, preventing contact of the upper and lower teeth. To accomplish this, the user may install the bite block on the side opposite from where the pain is occurring. For example, as depicted, the user installs the device on side 850 opposite the problematic tooth or teeth. By doing so, a gap 940 is produced, as depicted in FIG. 9. This gap is formed as a result of the thickness of the bite blocker, discussed above with respect to FIG. 5 for example. Because of the thickness of the bite block, the user is prevented from reducing the gap 940 such that opposing teeth touch. Referring back to FIG. 5, the gap 940 may be of various sizes, but is ideally from 5-7 mm depending on the user.

[0050] Additional alternative examples of the bite block are possible beyond those depicted, for example, the CTHBB may be constructed of a material which aids the user. For example, the material may be glow in the dark, or may be of a low enough density to float.

[0051] Certain more complex variations of the CTHBB may include integrated sensors in order to relay information to the patient or doctor. For example, temperature, bite pressure, moisture, tooth decay, bacteria presence, etc. For example, the CTHBB may be capable of sending small amounts of energy through a tooth in order to measure for any decay or cavities. Alternatively, a sensor may detect high levels of various bacteria, providing doctors with additional information. In these embodiments, the CTHBB may also include integrated wireless transceivers, such as a Bluetooth chipset, for sending and receiving data related to the sensed conditions to nearby computers and devices for review.

[0052] In some cases, it may be beneficial to form the bite blocker to cover more or less than half of the patient's teeth. For example, if one or more of a patient's front teeth become abscessed or are otherwise in pain, it may be beneficial to either form a bit blocker (pre-formed) that corresponds to part of one side of the patient's molars or back teeth, or two bite blockers that sit on either side of the tooth or teeth at issue. In other cases, it may be beneficial to form the bite blocker to cover more than half of the patient's teeth to further ensure that no contact is made with the tooth or teeth in pain (e.g., a % teeth bite blocker). In yet some cases, a smaller bite blocker device may be used to increase patient comfort, such as only corresponding to a third or quarter or any other fraction of the patient's teeth, for example based on location of the affected tooth. In some cases, the thickness of the anterior and/or posterior sections of the bite blocker that fit between the patient's teeth may be adjusted to account for the different amount of teeth that the bite blocker is positioned between or the intended location of the bite blocker. For example, if a smaller bite blocker is used, the thickness may be increased to better ensure that the affected tooth or teeth do not come in contact with other teeth. In additional examples, the posterior portion may include an elevated ridge in order to secure a better fit.

[0053] In additional embodiments, the Bite Block may be placed over the problematic tooth by forming a bridge over the affected tooth. This may be accomplished either as a two piece embodiment or as a single piece where there is no contact at the point over the tooth. This type of embodiment may be necessary if there are more than one affected tooth and they happen to be on opposite sides, or if there is some other reason that a bite block cannot be installed in the traditional, non-pain-side location.

[0054] In some cases, it may also be beneficial to apply or include as an additive, an ointment, medicine, antiseptic, or local anesthesia to the bite blocker. For example, pain reduction may be achieved by applying local anesthesia to the bite blocker. In such embodiments, the bite blocker may include small channels to receive and control the rate of exposure to the anesthesia. In alternative examples, the bite blocker may include additives within its construction such that the additive is released during wearing. While various aspects of the present disclosure have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the disclosure. Accordingly, the scope of the disclosure is not limited by the disclosure of the above examples.
