- a dental device 100 includes a mouthpiece 102 having an attached base 104 .
- the mouthpiece 102 can be separable from the base 104 .
- the mouthpiece 102 can include a biteplate 114 (with or without a separate mouthguard thereover, as described further below) and a mouthpiece extension 110 configured to connect with the base 104 .
- the biteplate 114 can be approximately U-shaped so as to cover the occlusal surfaces of all or nearly all of the patient's teeth.
- a motor 106 can be located in the mouthpiece 102 and configured to vibrate the mouthpiece 102 .
- the base 104 can include the electronics necessary to run the motor 106 .
- Contacts 108 can electrically connect the base 104 with the mouthpiece 106 .
- the motor 106 can be a counter-weighted motor extending in-line with the extension 110 (i.e. lay horizontal with its longitudinal axis parallel to the longitudinal axis of the extension 110 ).
- the motor 106 can include a counterweight 212 that is off-axis from the longitudinal axis of the motor 106 .
- the counterweight 212 moves up and down, causing the mouthpiece 102 to vibrate up and down, as shown by the arrows 113 a - d in FIG. 2 . Accordingly, referring to FIG.
- the motor 106 can be replaced with a pancake motor 2306 that includes a drum 2307 that moves up and down (shown by the arrows 2313 a,b in FIG. 23B ).
- the drum 2307 can be attached to two leads 2309 a,b that can connect the drum 2307 with a power source 2311 .
- the pancake motor 2306 can be placed in an extension 2320 on the base 2304 , as shown in FIG. 23A (the motor 2306 in an extension of the base is also shown in FIGS. 27A-C ) or can be located with an extension on the mouthpiece. Further, in some embodiments, the pancake motor 2306 can be placed such that the motor extends just inside the teeth, as shown in FIG.
- the motor 2306 can place axial vibratory force on the occlusal surface of the teeth, i.e., the mouthpiece can move axially away from the occlusal surface and then back onto the occlusal surface repetitively in a “smacking” motion.
- motors 106 and 2306 can be interchanged for any of the embodiments described herein.
- the motors used for the devices described herein can advantageously be small and lightweight.
- the motor can be less than 2 grams, such as less than 1.5 grams, such as less than or equal to 1.2 grams.
- the motor can be configured to require low current such that the power requirements are low.
- the voltage required for the motor to run can be less than 5 volts, such as less than 4 volts, less than 3 volts, or less than 2 volts.
- the motor requires between 0.5 and 4 volts, such as approximately 1.5 volts.
- the motor can advantageously consume less than 250 mW of power, such as less than 200 mW of power and/or can have an operating current of less than 100 mA, such as less than 75 mA, such as less than 65 mA.
- the overall device (including the mouthpiece and the base) can advantageously be less than 100 grams, such as less than 75 grams, less than 50 grams, less than 40 grams, or less than 35 grams.
- the motor 106 and/or motor 2306 can be configured to vibrate the mouthpiece 102 at frequencies between 60 HZ and 130 HZ, such as between 100 HZ and 120 HZ and at accelerations of 0.035 G to 0.100 G, such as 0.050 G to 0.060 G. These frequencies and accelerations can advantageously increase bone growth in the mouth.
- the motors 106 , 2306 can further be configured to oscillate between various vibration settings. For example, the motor 106 can oscillate between four predetermined frequencies. In one embodiment, the motor 106 oscillates between 60 hz at 0.035 G, 60 hz at 0.060 G, 120 hz at 0.035 G, and 120 hz at 0.060 G.
- a patient's teeth will be less likely to adapt to a particular vibration setting and will continue to strengthen and grow over time.
- the device 100 can include sensors 118 , such as piezoelectric sensors, configured to detect the acceleration or frequency of the vibration just proximate to the occlusal surfaces of the teeth.
- the sensors 118 can be placed, for example, on the outside or the inside of the biteplate.
- the sensors 108 can be connected to circuitry that includes a feedback loop for running the motor 106 . That is, when the mouthpiece 102 touches the teeth, the surface contact and/or force between the mouthpiece 102 and the teeth can dampen the vibrations and/or slow the motor down. The feedback loop can therefore be used to compensate for the slowed motor.
- a feedback loop can thus include applying vibration to the teeth with a dental device (such as device 100 or any device described herein) at step 371 .
- the acceleration or frequency of the vibration can be sensed or measured at step 373 at or near the teeth, such as with the sensors 118 .
- the sensed acceleration or frequency can be compared to the desired acceleration or frequency at step 375 .
- the feedback loop can then repeat.
- the acceleration or frequency of the vibration at the motor can be adjusted to obtain the desired acceleration or frequencies at the mouthpiece 102 regardless of the dampening effect caused by interaction with the teeth.
- the motor 106 can be located within the extension 110 of the mouthpiece 102 .
- the extension 110 can have a pocket 116 to house the motor 106 .
- the motor 106 can be placed close to the biteplate 114 , such as within 1 mm of the biteplate 114 , so that the motor 106 is located at least partially within the patient's mouth, i.e., is located intraorally (see FIG. 3C ).
- the counterweight 212 causing the vibration can be positioned so as to be located within the patient's mouth when the dental device 100 is in use.
- a dental device 400 can have a motor 406 that is located inside of the biteplate 414 . Further, the motor 406 can lay horizontal within the extension 410 , but be placed such that its longitudinal axis extends perpendicular to the long-axis of the extension 410 . The horizontal configuration of the motor still allows the counterweight 212 to provide a smacking motion while the perpendicular configuration allows the motor 406 to be located inside the teeth of a patient's mouth, for example sitting up against the roof of the mouth.
- the dental device 500 can have a motor 506 that is located inside of the extension and that lays horizontal and perpendicular to extension 510 .
- the horizontal configuration of the motor allows the counterweight 212 to provide a smacking motion, thereby enhancing tooth growth.
- the motors described herein can include an insulator theraround, such as a ceramic sleeve.
- the devices described herein need not include a mouthpiece configured to cover all of the teeth. Rather, mouthpieces specifically targeting particular teeth can be used. It is to be understood that the mouthpieces shown and described with respect to FIGS. 21A-21D and 24A-26C can be used with any of the motors, bases, and guards described herein.
- a mouthpiece 2402 can have a crescent shape biteplate 2414 configured to cover the social six teeth.
- Such a design can be advantageous, for example, for treating crowding in the social six teeth.
- a mouthpiece 2502 can have a double-hammer-shaped biteplate 2514 configured to cover only the molars.
- the biteplate 2514 can thus include a narrow central portion 2482 configured to rest on the tongue and two elongated edge portions 2484 a,b configured to rest on the occlusal surfaces of the molars. Further, the central portion 2482 can include a convex section 2499 configured to sit over the lounge for comfort and ease of use.
- a mouthpiece 2602 can have an elongate biteplate 2614 .
- the elongate biteplate 2614 can be configured to be placed on one side of the mouth and/or one quadrant of the teeth.
- the device 211 can include a rounded end or nub 213 .
- the nub 213 can include the motor 215 therein, which can be configured similarly to the motors described above.
- FIG. 21C-21D by having only a nub 213 rather than a full mouthpiece, specific individual teeth in need of treatment can be targeted. Variations on the nub are possible.
- the nub 2213 on device 2211 can include a brush 2207 on the end configured to provide a more gentle vibratory force on the teeth.
- the biteplate 714 for any of the mouthpieces described herein can include raised dimples 732 , or outward extensions. There can be approximately one dimple 732 for each tooth intended to be treated. Further, the dimples 732 can be spaced apart in such a manner as to approximately align with the center of some or all of the occlusal surfaces of a patient's teeth when the mouthpiece is in use. The dimples 732 can advantageously help the mouthpiece effectively smack the teeth by providing an extended point of contact to ensure that contact is made with each tooth. In some embodiments, the dimples 732 can be customized to a patient's tooth alignment. Each dimple 732 can have a peak that has a surface area of less than 70%, such as less than 50%, of the surface area of the corresponding tooth so as to place pressure on less than 75% or less than 50% of each tooth.
- the mouthpiece 802 (which can correspond to any mouthpiece described herein) can include two separable parts, the biteplate 814 and a mouthguard 834 .
- the biteplate 814 can be made of a hard material, such as metal.
- the mouthguard can be made of a softer material such as a polymer.
- the mouthguard 834 can be custom fit to the patient's mouth. By having a custom fit mouthguard 834 , the mouthpiece 802 can be more efficient and effective in applying the vibratory smacking force on a patient's teeth. As shown in FIG. 8B , the mouthguard 834 can include a hole 836 which can be used to place the mouthguard 834 over the biteplate 814 after formation.
- the mouthguard 834 can be produced quickly and easily on-site, e.g., at a dentist's office, within minutes by using an oven 940 .
- the mouthguard 834 can be made of a material such as silicone or an ethylene vinyl acetate copolymer, e.g., Elvax®, that is easily formable once warm.

- a mouthguard preform 933 i.e.
- one not yet formed to the teeth can be placed around a biteplate (which can be any of the biteplates described herein) and in the oven 940 .
- the mouthguard preform 933 and biteplate can be exposed to the heat source 941 for between 1 and 10 minutes at temperatures of between 120° and 200° F., less than 200°, or less than 175°.
- the mouthguard preform 933 warms, it can become slightly softer, thereby conforming to the shape of any dimples in the biteplate without losing its overall shape.
- the user can take the mouthguard preform 933 out of the oven 940 and have the patient bite down, leaving an impression of the teeth in the mouthguard preform 933 .
- the mouthguard preform 933 will be cool enough upon entering a patient's mouth to not burn the patient (in contrast to temperatures, for example, of over) 212 °. After the patient has bit down, and as the mouthguard preform 833 cools, it will retain its shape, thereby forming the final mouthguard 834 .
- the oven 940 can have a variety of configurations. In some embodiments, the oven 940 is relatively small such that it can easily sit on a counter or table at the office. In some embodiments, the oven 940 can include a drawer 932 with a handle, and the drawer 932 can be configured to hold the mouthguard preform 933 . In another embodiment, the oven 940 can include a shelf 992 and a hinged door 994 . The oven 940 can further include a power switch, an indicator light, a timer, and/or a display to enhance ease of use.
- the mouthguard 1134 can have vacuum ports 1144 to provide suction to exactly fit the mouthguard 1134 to all of the surfaces of the teeth before the mouthpiece 1134 cools completely.
- the vacuum ports 1144 can be removed after the mouthguard 1134 is fully formed.
- a mouthpiece 1302 of the dental devices described herein need not be formed to a patient's mouth, but can have a set shape. Further, as shown in FIGS. 13A-13F , the mouthpiece need not include a separate biteplate and mouthguard. Rather, the mouthpiece can be formed of a single piece.
- a base 604 can be connected to any of the mouthpieces described herein.
- the base 604 can include a housing 622 , an on-off switch 624 to control the vibration, electrical contacts 630 to electrically connect the base 604 with a mouthpiece, a battery 626 to power the motor, and a circuit board 628 to control the motor.
- the base 604 can be shaped such that it is easily held by a patient's hand. In one embodiment, the base 604 is small and light enough that it does not need to be gripped by the patient during use of the device.
- a base 2804 can be connected to any of the mouthpieces described herein.
- the base 2804 can include a handle 2881 configured to be easily held by a single hand and a mouthpiece connector 2887 .
- the handle 2881 can include a grip portion 2885 that can include indents 2883 , such as four indents, configured to provide comfortable resting spot for a person's fingers when gripping the handle 2881 .
- the handle 2881 can be curved such that the grip portion 2885 can be gripped with a hand without having to tilt the device forward or up.
- the angle between the grip portion 2885 and the mouthpiece connector 2887 can be between 30 and 60 degrees, such as approximately 45 degrees.

- Referring to
FIGS. 1A-1C , adental device 100 includes amouthpiece 102 having an attachedbase 104. Themouthpiece 102 can be separable from thebase 104. Themouthpiece 102 can include a biteplate 114 (with or without a separate mouthguard thereover, as described further below) and amouthpiece extension 110 configured to connect with thebase 104. In one embodiment (as shown inFIGS. 1A-1C ), thebiteplate 114 can be approximately U-shaped so as to cover the occlusal surfaces of all or nearly all of the patient's teeth. Further, amotor 106 can be located in themouthpiece 102 and configured to vibrate themouthpiece 102. The base 104 can include the electronics necessary to run themotor 106.Contacts 108 can electrically connect the base 104 with themouthpiece 106. - As shown in
FIG. 2 , themotor 106 can be a counter-weighted motor extending in-line with the extension 110 (i.e. lay horizontal with its longitudinal axis parallel to the longitudinal axis of the extension 110). Themotor 106 can include acounterweight 212 that is off-axis from the longitudinal axis of themotor 106. As a result, when themotor 106 rotates, as shown by thearrow 111 inFIG. 2 , thecounterweight 212 moves up and down, causing themouthpiece 102 to vibrate up and down, as shown by the arrows 113 a-d inFIG. 2 . Accordingly, referring toFIG. 3C , when themouthpiece 102 is placed in a patient's mouth and the dental device is 100 turned on, the vibration of themouthpiece 102 will place axial vibratory force on theocclusal surface 320 of the teeth, i.e., the biteplate 114 (and any guard placed thereover, as described below) will move axially away from theocclusal surface 320 of the teeth and then back onto theocclusal surface 320 of the teeth repetitively. This “smacking” up and down motion can simulate the chewing motion. By simulating the chewing motion, bone in the mouth (e.g., teeth), can be strengthened through the body's natural mechanisms, i.e., bone growth can occur due to the smacking motion. - In other embodiments, as shown in
FIGS. 23A-23B , themotor 106 can be replaced with apancake motor 2306 that includes adrum 2307 that moves up and down (shown by the arrows 2313 a,b inFIG. 23B ). Thedrum 2307 can be attached to twoleads 2309 a,b that can connect thedrum 2307 with apower source 2311. Thepancake motor 2306 can be placed in an extension 2320 on thebase 2304, as shown inFIG. 23A (themotor 2306 in an extension of the base is also shown inFIGS. 27A-C ) or can be located with an extension on the mouthpiece. Further, in some embodiments, thepancake motor 2306 can be placed such that the motor extends just inside the teeth, as shown inFIG. 28 . Similar to themotor 106, themotor 2306 can place axial vibratory force on the occlusal surface of the teeth, i.e., the mouthpiece can move axially away from the occlusal surface and then back onto the occlusal surface repetitively in a “smacking” motion. - It is to be understood that other types of motors can be used in place of
motor 106 ormotor 2306 to similarly cause thebiteplate 114 to smack the teeth. For example, the motor could be a piezoelectric motor, a linear motor, or an electromagnetic motor. Further, it is to be understood that themotors - The
motor 106 and/ormotor 2306 can be configured to vibrate themouthpiece 102 at frequencies between 60 HZ and 130 HZ, such as between 100 HZ and 120 HZ and at accelerations of 0.035 G to 0.100 G, such as 0.050 G to 0.060 G. These frequencies and accelerations can advantageously increase bone growth in the mouth. Themotors motor 106 can oscillate between four predetermined frequencies. In one embodiment, themotor 106 oscillates between 60 hz at 0.035 G, 60 hz at 0.060 G, 120 hz at 0.035 G, and 120 hz at 0.060 G. Advantageously, by oscillating between frequency and acceleration settings, a patient's teeth will be less likely to adapt to a particular vibration setting and will continue to strengthen and grow over time. - In some embodiments, as shown in
FIGS. 3A-3B , thedevice 100 can includesensors 118, such as piezoelectric sensors, configured to detect the acceleration or frequency of the vibration just proximate to the occlusal surfaces of the teeth. Thesensors 118 can be placed, for example, on the outside or the inside of the biteplate. Thesensors 108 can be connected to circuitry that includes a feedback loop for running themotor 106. That is, when themouthpiece 102 touches the teeth, the surface contact and/or force between themouthpiece 102 and the teeth can dampen the vibrations and/or slow the motor down. The feedback loop can therefore be used to compensate for the slowed motor. - Referring to
FIG. 3D , a feedback loop can thus include applying vibration to the teeth with a dental device (such asdevice 100 or any device described herein) atstep 371. The acceleration or frequency of the vibration can be sensed or measured atstep 373 at or near the teeth, such as with thesensors 118. The sensed acceleration or frequency can be compared to the desired acceleration or frequency atstep 375. Atstep 375, it can be determined whether the frequency or acceleration is too low. If so, then the frequency or acceleration can be increased atstep 377. If not, then it can be determined whether the sensed frequency or acceleration is too high atstep 379. If so, then the frequency or acceleration can be decreased atstep 381. The feedback loop can then repeat. Thus, the acceleration or frequency of the vibration at the motor can be adjusted to obtain the desired acceleration or frequencies at themouthpiece 102 regardless of the dampening effect caused by interaction with the teeth. - In one embodiment, shown in
FIGS. 3A-3B , themotor 106 can be located within theextension 110 of themouthpiece 102. Thus, for example, theextension 110 can have apocket 116 to house themotor 106. Themotor 106 can be placed close to thebiteplate 114, such as within 1mm of thebiteplate 114, so that themotor 106 is located at least partially within the patient's mouth, i.e., is located intraorally (seeFIG. 3C ). For example, thecounterweight 212 causing the vibration can be positioned so as to be located within the patient's mouth when thedental device 100 is in use. Having themotor 106 located intraorally advantageously both increases the ability of themouthpiece 212 to smack against the occlusal surfaces of the patient's teeth and avoids having the device extend too far outside of the mouth, which can cause discomfort to the patient if the base is intended to be used without hands. - Although the motor has been described as inside of and inline with the
extension 410 of themouthpiece 102, other configurations are possible. For example, referring toFIGS. 4A-4B , in one embodiment, adental device 400 can have amotor 406 that is located inside of thebiteplate 414. Further, themotor 406 can lay horizontal within theextension 410, but be placed such that its longitudinal axis extends perpendicular to the long-axis of theextension 410. The horizontal configuration of the motor still allows thecounterweight 212 to provide a smacking motion while the perpendicular configuration allows themotor 406 to be located inside the teeth of a patient's mouth, for example sitting up against the roof of the mouth. - Likewise, referring to
FIGS. 5A-5B , thedental device 500 can have amotor 506 that is located inside of the extension and that lays horizontal and perpendicular toextension 510. As described above, the horizontal configuration of the motor allows thecounterweight 212 to provide a smacking motion, thereby enhancing tooth growth. - In some embodiments, the motors described herein can include an insulator theraround, such as a ceramic sleeve.
- Referring to
FIGS. 21A-21D and 24A-26C , the devices described herein need not include a mouthpiece configured to cover all of the teeth. Rather, mouthpieces specifically targeting particular teeth can be used. It is to be understood that the mouthpieces shown and described with respect toFIGS. 21A-21D and 24A-26C can be used with any of the motors, bases, and guards described herein. - For example, referring to
FIGS. 24A-C , amouthpiece 2402 can have acrescent shape biteplate 2414 configured to cover the social six teeth. Such a design can be advantageous, for example, for treating crowding in the social six teeth. - As another example, referring to
FIGS. 25A-25C , amouthpiece 2502 can have a double-hammer-shaped biteplate 2514 configured to cover only the molars. Such a design can be advantageous, for example, for treating molar protraction or retraction. Thebiteplate 2514 can thus include a narrowcentral portion 2482 configured to rest on the tongue and two elongated edge portions 2484a,b configured to rest on the occlusal surfaces of the molars. Further, thecentral portion 2482 can include aconvex section 2499 configured to sit over the lounge for comfort and ease of use. - As another example, referring to
FIGS. 26A-26C , amouthpiece 2602 can have anelongate biteplate 2614. Theelongate biteplate 2614 can be configured to be placed on one side of the mouth and/or one quadrant of the teeth. - As another example, in one embodiment, shown in
FIGS. 21A-21D , thedevice 211 can include a rounded end ornub 213. Thenub 213 can include themotor 215 therein, which can be configured similarly to the motors described above. As shown inFIG. 21C-21D , by having only anub 213 rather than a full mouthpiece, specific individual teeth in need of treatment can be targeted. Variations on the nub are possible. For example, referring toFIG. 22 , the nub 2213 ondevice 2211 can include abrush 2207 on the end configured to provide a more gentle vibratory force on the teeth. - Referring to
FIGS. 7A and 7B , the biteplate 714 for any of the mouthpieces described herein can include raiseddimples 732, or outward extensions. There can be approximately onedimple 732 for each tooth intended to be treated. Further, thedimples 732 can be spaced apart in such a manner as to approximately align with the center of some or all of the occlusal surfaces of a patient's teeth when the mouthpiece is in use. Thedimples 732 can advantageously help the mouthpiece effectively smack the teeth by providing an extended point of contact to ensure that contact is made with each tooth. In some embodiments, thedimples 732 can be customized to a patient's tooth alignment. Eachdimple 732 can have a peak that has a surface area of less than 70%, such as less than 50%, of the surface area of the corresponding tooth so as to place pressure on less than 75% or less than 50% of each tooth. - Referring to
FIG. 8A , the mouthpiece 802 (which can correspond to any mouthpiece described herein) can include two separable parts, thebiteplate 814 and amouthguard 834. Thebiteplate 814 can be made of a hard material, such as metal. The mouthguard can be made of a softer material such as a polymer. - In some embodiments, the
mouthguard 834 can be custom fit to the patient's mouth. By having a customfit mouthguard 834, themouthpiece 802 can be more efficient and effective in applying the vibratory smacking force on a patient's teeth. As shown inFIG. 8B , themouthguard 834 can include a hole 836 which can be used to place themouthguard 834 over thebiteplate 814 after formation. - Referring to
FIGS. 9A and 9B , themouthguard 834 can be produced quickly and easily on-site, e.g., at a dentist's office, within minutes by using anoven 940. To form amouthguard 834 using theoven 940, themouthguard 834 can be made of a material such as silicone or an ethylene vinyl acetate copolymer, e.g., Elvax®, that is easily formable once warm. Theoven 940 can include aheat source 941, such as infrared bulbs, a heat lamp, or heating coils, configured to heat up themouthguard 814. A mouthguard preform 933 (i.e. one not yet formed to the teeth) can be placed around a biteplate (which can be any of the biteplates described herein) and in theoven 940. Themouthguard preform 933 and biteplate can be exposed to theheat source 941 for between 1 and 10 minutes at temperatures of between 120° and 200° F., less than 200°, or less than 175°. Advantageously, as themouthguard preform 933 warms, it can become slightly softer, thereby conforming to the shape of any dimples in the biteplate without losing its overall shape. Further, once themouthguard preform 933 is warmed up sufficiently, the user can take themouthguard preform 933 out of theoven 940 and have the patient bite down, leaving an impression of the teeth in themouthguard preform 933. Advantageously, by using temperatures of between 120° and 200° F., less than 200°, or less than 175° to heat the mouth guard, themouthguard preform 933 will be cool enough upon entering a patient's mouth to not burn the patient (in contrast to temperatures, for example, of over)212°. After the patient has bit down, and as the mouthguard preform 833 cools, it will retain its shape, thereby forming thefinal mouthguard 834. - The
oven 940 can have a variety of configurations. In some embodiments, theoven 940 is relatively small such that it can easily sit on a counter or table at the office. In some embodiments, theoven 940 can include adrawer 932 with a handle, and thedrawer 932 can be configured to hold themouthguard preform 933. In another embodiment, theoven 940 can include ashelf 992 and a hingeddoor 994. Theoven 940 can further include a power switch, an indicator light, a timer, and/or a display to enhance ease of use. - In some embodiments, shown in
FIG. 11 , themouthguard 1134 can havevacuum ports 1144 to provide suction to exactly fit themouthguard 1134 to all of the surfaces of the teeth before themouthpiece 1134 cools completely. Thevacuum ports 1144 can be removed after themouthguard 1134 is fully formed. - As shown in
FIGS. 13A-13F , amouthpiece 1302 of the dental devices described herein need not be formed to a patient's mouth, but can have a set shape. Further, as shown inFIGS. 13A-13F , the mouthpiece need not include a separate biteplate and mouthguard. Rather, the mouthpiece can be formed of a single piece. - Any of the mouthpieces described herein can be connected to a base, such as
base 104 or an alternative base. For example, referring toFIG. 6 , a base 604 can be connected to any of the mouthpieces described herein. The base 604 can include ahousing 622, an on-off switch 624 to control the vibration,electrical contacts 630 to electrically connect the base 604 with a mouthpiece, abattery 626 to power the motor, and acircuit board 628 to control the motor. The base 604 can be shaped such that it is easily held by a patient's hand. In one embodiment, thebase 604 is small and light enough that it does not need to be gripped by the patient during use of the device. - As another example, referring to
FIGS. 27A-28 , abase 2804 can be connected to any of the mouthpieces described herein. Thebase 2804 can include ahandle 2881 configured to be easily held by a single hand and a mouthpiece connector 2887. Thehandle 2881 can include agrip portion 2885 that can includeindents 2883, such as four indents, configured to provide comfortable resting spot for a person's fingers when gripping thehandle 2881. As shown inFIG. 28 , thehandle 2881 can be curved such that thegrip portion 2885 can be gripped with a hand without having to tilt the device forward or up. For example, the angle between thegrip portion 2885 and the mouthpiece connector 2887 can be between 30 and 60 degrees, such as approximately 45 degrees. Referring back toFIGS. 27A-27C , thebase 2804 can house the power source, such as a battery, for the motor therein. Thebase 2804 can include an on-off switch 2824 to control the vibration. Further, in some embodiments, thebase 2804 can include a battery indicator light 2893 thereon to indicate the amount of battery left. In some embodiments, thebase 2804 can also include contacts 2891 thereon to interact with a charging station, as described below. - Referring to
FIGS. 12A-12D , anotherexemplary base 1204 can be used with any of the mouthpieces described herein. As shown inFIGS. 12A-12D , thebase 1204 can include amotor 1206 therein (in place of or in addition to the motor in the mouthpiece). By including the motor in the base, there is advantageously more room for the connection to the battery while allowing the mouthpiece to be as slim as possible. For example, themouthpiece 1202 can be free of a motor. - As shown in
FIGS. 12A-12D, and 18-20 the mouthpieces can be configured to connect to the base in a variety of ways. For example, as shown inFIGS. 12A-12B , thebase 1204 can include anextension 1220 to house themotor 1206, while theextension 1210 of themouthpiece 1202 can include ahole 1221 therein to fit over or house theextension 1220 of thebase 1204. In contrast, in reference toFIGS. 12C-12D , thebase 1204 can include anextension 1220 having ahole 1222 therein that both holds themotor 1206 and engages with our houses theextension 1210 of themouthpiece 1202. Theextension 1210 of themouthpiece 1202 can include a corresponding cut-out 1232 to fit over themotor 1206 when it is snapped into thebase 1204. - In one embodiment, as shown in
FIG. 18 , thebase 1804 and themouthpiece 1802 can be attached together with amechanical connector 1844 that can set the orientation of connection and that can be released through arelease button 1846. In another embodiment, shown inFIG. 29 , thebase 1904 and themouthpiece 1902 can be attached together through a fork-typemechanical connection 1948; squeezing the fork portions together can lock or unlock theconnection 1948. In yet another embodiment, shown inFIG. 20 , atightening collar 2050 can be used to connect abase 2004 andmouthpiece 2002. - Further, as shown in
FIGS. 14A-14B , in some embodiments, the dental devices described herein can include aflexible portion 1444 between themouthpiece 1402 and thebase 1404. For example, theflexible portion 1444 can include a series of cut-outs that allow theportion 1444 to easily bend. Theflexible portion 1444 to provide enhanced comfort to the patient, for example, by limiting the amount of vibration that occurs outside of the mouth and by reducing the amount of torque that occurs on the mouth through the bite plate if the base is torqued suddenly. The flexible portion can have an oval-like cross-section that easily conforms to the patient's mouth, thereby enhancing the comfort of the patient. - As shown in
FIGS. 15-17 , the devices described herein can be configured to be charged in a charging station, for example using a standard mini usb connection. As shown inFIG. 15A , the charging station can include aprotective covering 1502 configured to protect the device while not in use. Theprotective covering 1502 can then be placed in a charging base (not shown inFIGS. 15A-15B ). As shown inFIGS. 16A-16D , the chargingstation 1600 can include aprotective covering 1602 and acharging base 1604. Aconnector slot 1606 can be used to sit thecase 1602 in thecharging base 1604. As shown inFIG. 16C , chargingpins 1608 can connect from thecharging base 1604 through the protecting covering 1602 and into thedevice 1610 to charge the device. An indicator light 1612 can indicate whether the chargingstation 1600 is charging. Asimilar station 1700 is shown inFIGS. 17A-17D . It is to be understood that other sizes, shapes, and types of charging stations could be used. - Once formed and assembled, the dental devices described herein can be used to strengthen the bone around teeth and tighten the ligaments around teeth such as for retention, e.g. orthodontic retention after braces are removed. For example, the device can be placed in the mouth for less than 10 minutes per day, such as less than 6 minutes, such as approximately 5 minutes, less than 5 minutes, or less than 1 minute per day for less than or equal to 180 days, less than or equal to 120 days, or less than or equal to 90 days to tighten the periodontal ligament after orthodontics. Such use can be in addition to or in place of traditional retainers. Use of the device can advantageously significantly decrease the time required for tightening of the periodontal ligament (from the average of six months to a year). Further, in some embodiments, the dental device can also be used for less than 2 minutes per day, such as less than 1 minute per day, on a continuing basis to provide general tooth strengthening. Further, the dental devices described herein can also be used for strengthening bone during dental implant procedures, tightening ligaments, strengthening bone after periodontics cleaning and procedures, such as after bone grafting.
