Definitions
- This invention relates to dentistry and, more particularly, to novel systems and methods for treating bruxism.
- Bruxism or grinding and clenching of teeth, can cause irreversible damage to teeth and the temporomandibular joint (TMJ).
- TMJ temporomandibular joint
- bruxism may contribute to a temporomandibular disorder (TMD). Accordingly, what is needed is an apparatus and method for preventing bruxism or the negative consequences thereof.
- the dental appliance may comprising an upper portion corresponding to one or more upper or maxillary teeth of a patient and a lower portion corresponding to one or more lower or mandibular teeth of the patient.
- the upper and lower portions may each include a base and a feature. Each base may be shaped to selectively engage one or more teeth of a patient. Each feature may be secured to a corresponding base. Thus, each base may interface between a corresponding feature and certain teeth of a patient.
- the upper and lower portions may be worn simultaneously to control one or more mandibular loadings, motions, or the like.
- features may be positioned and shaped to interface or interact with one another in a particular manner.
- opposing features may be located on or secured to anterior areas of the respective bases.
- the features may be shaped, sized, or positioned such that contact therebetween may be or comprise an initial, primary, or exclusive point of contact for forces of occlusion passing form mandibular teeth to maxillary teeth of the corresponding patient.
- an appliance may cause all or a large portion of the forces of occlusion to be directed to the front of the mouth or to the front teeth.
- an appliance may prevent the patient from clenching or grinding teeth.
- a first feature may comprise an indentation or recess and a second, opposite feature may comprising a protrusion or recess.
- the opposing features may maintain a certain initial separation between an upper and lower jaw.
- a protrusion may pass or move out of alignment with an opposing indentation and begin to "climb" the walls of the indentation.
- a new, greater separation between an upper and lower jaw may be applied or enforced.
- a greater separation in a lateral excursion may lower the strain imposed on the TMJ.
- a first feature and a second, opposing feature may each comprise a protrusion.
- protrusions When directly contacting and opposing one another, such protrusions may maintain a certain initial separation between an upper and lower jaw. However, during a lateral excursion or the like, one protrusion may pass or move out of alignment with the other protrusion. Accordingly, in an misaligned position, a new, lower separation between an upper and lower jaw may be allowed or permitted. In certain embodiments or applications, or with certain patients, a lower separation may lower the strain imposed on the TMJ in a lateral excursion.

- bruxism may cause unnecessary muscle strain, tension, and pain.
- jaw muscles may be contracted and strained for extended periods of time. Additionally, grinding and clenching of teeth may cause muscle strain and tension in other areas. For example, bruxism may produce muscle strain, tension, and pain in the muscles of the neck. Bruxism may cause sleep problems as well.
- headaches may be a symptom of bruxism.
- an appliance 10 in accordance with the present invention may cure a host of ailments.
- an appliance 10 may protect teeth from harmful abrasion and unnecessary wear.
- An appliance 10 may also reduce inflammation of the periodontal ligament (PDL), reduce pulpitis of the teeth, preserve an orthodontic tooth position, reduce muscle strain, tension, and pain in the muscles of the jaw, reduce muscle strain, tension, and pain in the muscles of the neck, enable a user to enter deeper levels of sleep, and/or reduce head aches.
- PDL periodontal ligament
- an appliance 10 may be described in terms of a longitudinal direction 11a, lateral direction l ib, and transverse direction 11c.
- the longitudinal, lateral, and transverse directions 11a, l ib, 11c may extend orthogonally with respect to one another.
- an appliance 10 in accordance with the present invention may include an upper portion 12 corresponding to (e.g., engaging, covering, being worn over) one or more upper or maxillary teeth 14 of a patient and a lower portion 16 corresponding to (e.g., engaging, covering, being worn over) one or more lower or mandibular teeth 18 of the patient.
- the upper and lower portions 12, 16 of an appliance 10 may be worn simultaneously.
- An appliance 10 may cover all of the teeth of a patient or some subset thereof.
- an upper portion 12 may engage or cover all or substantially all maxillary teeth 14 of a patient and a lower portion 16 may engage or cover all or substantially all mandibular teeth 18 of the patient. This may allow for orthodontic retention, product delivery (e.g., application of a whitening product to the teeth), or the like or a combination thereof.
- one or both of an upper portion 12 and a lower portion 16 may respectively cover less than (e.g., substantially less than) all of the maxillary and mandibular teeth of a patient.
- upper and lower portions 12, 16 in accordance with the present invention may each include a base 20 and a feature 22.
- an upper portion 12 may include a first base 20a and a first feature 22a
- a lower portion 16 may include a second base 20b and a second feature 22b.
- a base 20 may be shaped to selectively engage one or more teeth of a patient.
- a feature 22 may be secured to a base 20.
- a base 20 may interface between a feature 22 and certain teeth of a patient.
- a base 20 may be custom made to closely fit certain teeth of a patient. Accordingly, when the base 20 is applied to the one or more teeth, the base 20 may tend to stay there by mechanical gripping, suction, or the like or some combination thereof.
- a corresponding feature 20 may be held in a desired orientation or position with respect to the teeth. However, the base 20 and corresponding feature 22 may be removed from the patient by simply pulling the base 20 away from the corresponding teeth.
- an appliance 10 may include features 22 positioned opposite one another.
- a first feature 22a of an upper portion 12 may be positioned opposite a second feature 22b of a lower portion 16. Accordingly, mandibular motion of a patient (e.g., biting down) may result in a first feature 22a contacting a second feature 22b.
- features 22 may be positioned and shaped to interface or interact with one another in a particular manner.
- a first feature 22a may comprise an indentation 24 or recess 24 and a second feature 22b may comprise a protrusion 26 or mound 26.
- a first feature 22a may comprise a protrusion 26 or mound 24 and a second feature 22b may comprise an indentation 24 or recess 24.
- Figures 1-3 show an indentation 24 forming part of an upper portion 12 and a protrusion 26 forming part of a lower portion 16, in other embodiments, a protrusion 26 may form part of an upper portion 12 and an indentation 24 may form part of a lower portion 16.
- features 22 may be positioned and shaped to interface or interact with one another to control, direct, or influence the mandibular motion, mandibular loadings, or the like of a corresponding patient.
- opposing first and second features 22a, 22b may be located on or secured to anterior areas of the respective first and second bases 20a, 20b.
- the first and second features 22a, 22b may be shaped, sized, or position such that contact therebetween may be or comprise an initial, primary, or exclusive point of contact for forces of occlusion (e.g., biting loads) or the like passing form mandibular teeth to maxillary teeth of the corresponding patient.
- forces of occlusion e.g., biting loads
- an appliance 10 may cause all forces of occlusion to be directed to the front of the mouth or to the front teeth (e.g. , maxillary central incisors, maxillary lateral incisors, mandibular central incisors, mandibular lateral incisors, or the like or combinations or sub-combinations thereof).
- the brain of a patient may not allow the muscles of mastication to produce the same force of occlusion when pressure is only on the front teeth. That is, an appliance 10 may not allow the muscles around the joint to contract at full strength.
- an appliance may 10 may prevent a patient from clenching or grinding teeth and provide to the patient the benefits associated therewith.
- An appliance 10 in accordance with the present invention may be manufactured in any suitable manner.
- a base 20 and corresponding feature 22 may be made as a monolithic unit by three-dimensional printing, photo-activation, machining, casting, molding, or the like.
- impressions e.g., actual or digital impressions
- Polymeric material e.g., acrylic sheets
- the bases 20 may be custom made to closely fit selected teeth of a patient. Once the bases 20 are formed, appropriate features 22 may be applied thereto.
- Features 22 in accordance with the present invention may be manufactured from any suitable material or combinations of materials. Suitable materials may include polymers, ceramics, metals, metal alloys, or the like. In certain embodiments, features 22 be manufactured as separate, standardized pieces. That is, while a base 20 may be custom made to fit only one patient, a feature 22 may be an "off-the-shelf item that may be applied to various bases 20. For example, features 22 may be manufactured in one size or in a relative small set of sizes (e.g., small, medium, large, etc.). Then, once a base 20 has been made, an appropriate feature 22 may be selected, positioned, and bonded to an anterior area of the base 20. Alternatively, a feature 22 may be formed by hand from a polymeric material, epoxy, or the like that is molten, in a softened condition, uncured, or the like and urged against or otherwise bonded to a base 20.
- a feature 22a corresponding to an upper portion 12 may be positioned differently than a feature 22b corresponding to a lower portion 16. This difference may ensure that the two features 22a, 22b properly align when a lower jaw of the corresponding patient is in a desired position (e.g., a neutral, central, forward, lower, or mouth-slightly-open position, or a combination or sub-combination thereof).
- This desired position may be selected to control jaw position and postural muscles of the neck and head to open the airway of the patient, thereby decreasing snoring and reducing the incidence or symptoms of sleep apnea.
- a feature 22a corresponding to an upper portion 12 may be positioned primarily or largely posterior and/or inferior to the maxillary central incisors, while a feature 22b corresponding to a lower portion 16 may be positioned primarily or largely superior (and possible anterior or posterior to) the mandibular central incisors.
- a feature 22 providing or comprising an indentation 24 or recess 24 may have any suitable configuration.
- such a feature 22 may include a first side having a concave surface 28 forming a concavity, which concavity may be the indentation 24 or recess 24.
- the feature 22 may also include a second side having a channel 30 facilitating securement of the feature 22 to a base 20.
- a channel 30 may provide a location for bonding material to be applied to a feature 22 before the feature 22 is applied to a corresponding base 20.
- an aperture 30 or channel 30 may include one or more curved surfaces 32 that track or loosely follow a typical curve associated with an anterior area of a base 20. That is, as a base 20 may curve to accommodate the natural positioning of the incisors, cuspids, bicuspids, etc. of the patient, so a channel 30 or curved surface 32 thereof may curve to accommodate the shape of the base 20. Accordingly, the curved surface 32 may facilitate positioning and stabilizing of a feature 22 with respect to a corresponding base 20.
- a channel 30 may divide a feature 22 into an anterior portion 34 and a posterior portion 36.
- an anterior portion 34 When connected to a base 20 and applied to a patient, an anterior portion 34 may be largely or exclusively position anterior to the teeth (e.g., incisors, cuspids, etc.) of the patient.
- a posterior portion 36 When connected to a base 20 and applied to a patient, a posterior portion 36 may be positioned largely or exclusively posterior to those teeth.
- one curved surface 32a or side of a channel 30 may be part of an anterior portion 34, while another, opposite curved surface 32b or side of the channel 30 may be part of a posterior portion 36.
- a channel 30 may have any suitable width in the longitudinal direction 11a between such opposing surfaces 32a, 32b.
- a channel 30 may have a width just wide enough to accommodate the outer or exposed portions of the incisors (or the incisors and cuspids) and the thickness of the base 20 extending thereover.
- a channel 30 may have a width that significantly wider than the teeth corresponding thereto.
- a channel 30 may have one curved surface 32a that tracks or loosely follows the curvature of the anterior side of the teeth, while an opposing curved surface 32b extends posteriorly away from a posterior side of the teeth.
- the wide channel 30 may increase the stability with which the feature 22 may be secured to a base 20. Such stability may be helpful when a feature 22 comprises an indentation 24 or recess 24 positioned largely or entirely posterior to the corresponding teeth.
- the width in the longitudinal direction 11a between opposing surfaces 32 of a channel 30 may be substantially constant across a feature 22 in the lateral direction 1 lb. That is, the width of the channel 30 may be substantially constant from one end of the channel 30 to the other. Alternatively, the width may vary.
- a channel 30 may have the smallest width at the lateral 1 lb extremes thereof.
- the channel 30 may be the widest at a middle portion thereof.
- curvature of the opposing surfaces 32 of a channel 30 may be complementary or track one another. For example, if a curved surface 32a corresponding to an anterior portion 34 of a feature 22 is primarily concave, then an opposing curved surface 32b corresponding to a posterior portion 36 of the feature 22 may be primarily convex. Alternatively, curvature of the opposing surfaces 32 of a channel 30 may be substantially opposite. For example, if a curved surface 32a corresponding to an anterior portion 34 of a feature 22 is primarily concave, then an opposing curved surface 32b corresponding to a posterior portion 36 of the feature 22 may also be primarily concave and extend away from the other surface 32a.
- a channel 30 in accordance with the present invention may have any suitable floor 38 or ceiling 38 connecting the opposing curved surfaces 32 or sides.
- a floor 38 or ceiling 38 may be substantially flat.
- a floor 38 or ceiling 38 may be curved (e.g., smoothly curving and transitioning from one curved surface 32a to the opposing curved surface 32b).
- a feature 22 corresponding to an indentation 24 or recess 24 may have a channel 30 with a floor 38 or ceiling 38 that is substantially flat, while a feature 22 corresponding to a protrusion 26 or mound 26 may have a channel 30 with a floor 38 or ceiling 38 that is smoothly curved as it transitions from one curved surface 32a to the opposing curved surface 32b.
- the various edges and surfaces of a feature 22 may be radiused and smooth. Smooth, radiused edges and smooth surfaces may enhance the comfort experienced by a patient in wearing an appliance 10 in accordance with the present invention.
- an upper lip of a patient may rest on an anterior portion 34 of a feature 22 of an upper portion 12 of an appliance 10. Accordingly, the anterior portion 34 may be radiused and smooth to avoid irritating or harming the tender tissues on the interior of the upper lip.
- the tip of a tongue of a patient may rest on a posterior portion 36 of a feature 22 of an upper portion 12 of an appliance 10. Accordingly, the posterior portion 34 may be radiused and smooth to avoid irritating or harming the tongue of the patient.
- a feature 22 providing or comprising a protrusion 26 or mound
- such a feature 22 may include a first side having a convex surface 40 forming the protrusion 26 or mound 26.
- the feature 22 may also include a second side having an aperture 30 or channel 30 facilitating securement of the feature 22 to a base 20.
- such an aperture 30 or channel 30 may include one or more curved surfaces 32 that track or loosely follow a typically curve associated with an anterior area of a base 20.
- features 22 may change a position of a lower jaw of a patient. For example, when lateral excursions (e.g., when a lower jaw moves side to side in the lateral direction l ib) take place, opposing features 22 may lessen the strain in the TMJ. That is, when directly contacting and opposing one another, the opposing features 22 may maintain a certain initial separation 42 between an upper and lower jaw. However, during a lateral excursion, a protrusion 26 may pass or move out of alignment with an opposing indentation 26. That is, a protrusion 26 may move along and "climb" the walls of an indentation 24. In a laterally misaligned position, a new, greater separation 44 between an upper and lower jaw may be applied or enforced. In certain embodiments or with certain patients, this greater separation 44 in a lateral excursion may lower the strain imposed on the TMJ.
- lateral excursions e.g., when a lower jaw moves side to side in the lateral direction l ib
- a protrusion 26 may pass or move out of alignment with an opposing indentation 24.
- a longitudinal excursion may cause a protrusion 26 may move along and "climb" the walls of an indentation 24. Accordingly, in a longitudinally misaligned position, a new, greater separation 44 between an upper and lower jaw may also be applied or enforced.
- one or both features 22 may be formed such that longitudinal excursions produce no significant change in the initial separation 42 between an upper and lower jaw.
- an indentation 24 may form a channel extending longitudinally 11a through an corresponding feature 22.
- a lateral excursion may cause a protrusion 26 to contact and climb the sides of the channel to produce a greater spacing 44, while a longitudinal excursion may permit the protrusion 22 to simply slide along the channel without changing the initial spacing 42.
- a protrusion 26 and indentation 24 in accordance with the present invention may have any suitable fit or relative size therebetween.
- a protrusion 26 may be significantly thinner than an opposing indentation 24 in the longitudinal direction 11a, the lateral direction 1 lb, or both the longitudinal and lateral directions 11a, 1 lb.
- a protrusion 26 may move within an opposing indentation 24 through a sizable range of motion in the longitudinal direction 11a, the lateral direction l ib, or both the longitudinal and lateral directions 11a, 1 lb, respectively.
- a protrusion 26 may be closer to the size of an opposing indentation 24 in the longitudinal direction 11a, the lateral direction l ib, or both the longitudinal and lateral directions 11a, l ib. In such embodiments, a protrusion 26 may move within the indentation 24 through a smaller range of motion in the longitudinal direction 11a, the lateral direction l ib, or both the longitudinal and lateral directions 1 la, 1 lb, respectively. In certain embodiments, a protrusion 26 may substantially match the size of an opposing indentation 24 in one or both of the longitudinal and lateral directions 1 la, 1 lb. Thus, longitudinal and/or lateral excursions may only be permitted to the extent that the protrusion 26 exits the opposing indentation 24.
- the relative sizing and shapes of a protrusion 26 and opposing indentation 24 may define to a certain degree the range of motion of a lower jaw with respect to an upper jaw. Additionally, in selected embodiments, the relative sizing and shapes of a protrusion 26 and opposing indentation 24 may define or generate a biasing force urging a lower jaw into a particular alignment (e.g., a neutral and/or centered alignment) with an upper jaw. For example, the sides of an indentation 24 may bias an opposing protrusion 26 toward a center of the indentation 24.
- each feature 22 and the surfaces 28, 40 thereof may extend gradually and smoothly from the surrounding area of the respective portions 12, 16. Accordingly, in such embodiments, when in contact with one another, opposing features 22 may move smoothly over one another (e.g. , in lateral excursions, longitudinal excursions, or both lateral and longitudinal excursions).
- Indentations 24 and protrusions 26 in accordance with the present invention may have any suitable depth 48 and height 50, respectively.
- the depth 48 of a particular indentation 24 may be less than or substantially equal to the height 50 of a corresponding protrusion 26.
- the height 50 of a protrusion 26 may be in a range from about 1 mm to about 12 mm and preferably from about 3 mm to about 8 mm.
- the depth 48 of an indentation 24 may also be in a range from about 1 mm to about 12 mm and preferably from about 3 mm to about 8 mm.
- indentations 24 and protrusions 26 in accordance with the present invention may have any suitable base widths 52, 54, respectively.
- the base width 52 of a particular indentation 24 in both the longitudinal and lateral directions 11a, l ib may be greater than or substantially equal to the base width 54 of a corresponding protrusion 26 in both the longitudinal and lateral directions 11a, l ib.
- the base width 54 of a protrusion 26 in the lateral direction l ib may be in a range from about 2 mm to about 15 mm and preferably from about 5 mm to about 10 mm.
- the base width 52 of an indentation 24 in the lateral direction 1 lb may be in a range from about 3 mm to about 30 mm and preferably from about 10 mm to about 20 mm.
- the base width 54 of a protrusion 26 in the longitudinal direction 11a may be less than the base width 52 of an indentation 24 in the lateral direction l ib.
- the base width 54 of a protrusion 26 in the longitudinal direction 11a may be in a range from about 2 mm to about 12 mm and preferably from about 5 mm to about 8 mm.
- the base width 52 of an indentation 24 in the longitudinal direction may be in a range from about 3 mm to about 20 mm and preferably from about 8 mm to about 15 mm.
- an appliance 10 may include two opposing protrusions 26 or mounds 26, one on the anterior section of each portion 12, 16.
- opposing protrusions 26 on the anterior sections of the upper and lower portions 12, 16 may form an initial, primary, or exclusive point of contact between an upper jaw and a lower jaw. This may cause all forces of occlusion to be directed to the front of the mouth or to the front teeth and, therefore, prevent a patient from clenching or grinding teeth and provide to the patient the benefits associated therewith.
- opposing protrusions 26 may change a position of a lower jaw.
- opposing protrusions 26 may lessen the strain in the TMJ. That is, when directly contacting and opposing one another, two protrusions 26 may maintain a certain initial separation 56 between an upper and lower jaw. However, during a lateral excursion, one protrusion 26a may pass or move out of alignment with the other protrusion 26b. That is, one protrusion 26a may slide off of the other protrusion 26b. In an misaligned position, a new, lower separation 58 between an upper and lower jaw may be allowed or permitted. In certain embodiments or applications, or with certain patients, a lower separation 58 may lower the strain imposed on the TMJ in a lateral excursion.
- one protrusion 26a may pass or move out of alignment with the other protrusion 26b. In an misaligned position, a new, lower separation 58 between an upper and lower jaw may be allowed or permitted. Alternatively, one or both protrusions 26 may be formed such that longitudinal excursions produce no new or lower separation 58 between an upper and lower jaw. In selected embodiments, each protrusion 26 may extend gradually and smoothly from the surrounding area of the respective portions 12, 16. Accordingly, in such embodiments, when in contact with one another, opposing protrusions 26 may move smoothly over one another (e.g., in lateral excursions, longitudinal excursions, or both lateral and longitudinal excursions).
- Protrusions 26 in accordance with the present invention may have any suitable height 60.
- opposing protrusions 26a, 26b may have different heights 60a, 60b.
- the heights 60a, 60b of the opposing protrusions 26a, 26b may be equal.
- the height 60 of each protrusion 26 may be in a range from about 1 mm to about 6 mm and preferably from about 3 mm to about 6 mm.
- the width (e.g. , base width) of each protrusion 26 may be in a range from about 5 mm to about 20 mm and preferably from about 10 mm to about 15 mm.
- An appliance 10 with opposing protrusions 26 maybe manufactured in any suitable manner.
- impressions of a patient's teeth may be taken, models of patient's teeth may be fabricated, and then polymeric material (e.g., acrylic sheets) may be applied to and/or formed around the modeled teeth to form appropriate bases 20.
- Protrusions 26 may then be positioned appropriately and bonded to the bases 20 on the anterior area thereof.
- Bonding a protrusion 26 to a base 20 may be done by bonding on a feature 22 manufactured as separate, standardized piece.
