described herein is a device for the treatment of bruxism . a first embodiment may include a one - piece system , and a second embodiment may include a two - piece system . in either embodiment , the device includes a clench sensor and a nasal airway obstructor . fig1 illustrates an example embodiment of a bruxism treatment device 300 . bruxism treatment device 300 includes mouthpiece 302 , clench sensor 301 , and nasal airway obstructor 400 . in an example embodiment , clench sensor 301 is embedded within mouthpiece 302 . alternatively , clench sensor 301 may be disposed on a top or bottom of the mouthpiece 302 . nasal airway obstructor 400 includes nasal obstructors 421 and electro - mechanism drives 422 . the mouthpiece 302 is operatively connected to nasal airway obstructor 400 to provide a means of communication . fig2 illustrates an example embodiment of a two - piece bruxism treatment device 300 . mouthpiece 302 may be separate from nasal airway obstructor 400 . mouthpiece 302 includes clench sensor 301 and wireless signal transmitter 303 . nasal airway obstructor 400 includes hood 411 , seal 413 , and straps 412 a , 412 b . hood 411 may be sized and shaped to cover a user &# 39 ; s nose , for example in a cup or hood configuration . seal 413 encircles an edge of hood 411 to create seal of hood 411 against a user &# 39 ; s face . straps 412 a , 412 b extend from either side of nasal airway obstruct 400 and around a user &# 39 ; s head . the mouthpiece 302 is shown in more detail at fig3 . mouthpiece 302 include at least one clench sensor 301 . clench sensor 301 detects the clenching behavior of a user and sends a feedback signal ( biofeedback ) to the nasal airway obstructor 400 . in one embodiment of the invention , the clench sensor 301 is embedded in mouthpiece 302 . the clench sensor 301 can be an electrical switch , strain gauge , piezoelectric crystal , fluidic displacement device , or other similar mechanism . a wireless signal transmitter 303 ( not shown ) can be embedded in the mouthpiece 302 to transmit the clench data to the data processing unit 416 electromagnetically in either a one - piece system or a two - piece system . alternatively , in a one - piece system , a clench sensor 301 can communicate the clench behavior to the nasal airway obstructor 400 via passages 304 , which are contained within a conduit connection 305 . conduit connection 305 extends through the lips of the user to the data processing unit 416 of the nasal airway obstructor 400 . mouthpiece 302 may be a variety of sizes and shapes . in an embodiment , the mouthpiece 302 may be custom fitted to the user &# 39 ; s teeth . an example mouthpiece 302 may cover the top teeth , the bottom teeth , or both . example materials of a mouthpiece 302 may include an elastic material such as rubber or plastic , or may be an inelastic material such as other plastics with little or no flexibility . the clench signal can be transmitted electrically , electromagnetically , mechanically , via fluid power transmission , or other similar mechanism . in an alternative embodiment , bruxism treatment device 300 may accomplish clench detection utilizing physical or electrical feedback from the external musculoskeletal structure of the user &# 39 ; s orofacial region . the nasal airway obstructor 400 obstructs the user &# 39 ; s nasal airway to prevent the user from breathing through their nose . in an embodiment of the invention shown in fig4 , the nasal airway obstructor 400 is comprised of a nasal hood assembly , which is comprised of a cup - shaped hood 411 and is held to the user &# 39 ; s face with straps 412 a , 412 b and maintains an airtight seal 413 to the user &# 39 ; s face and encloses the nose . an airway valve 414 may control airflow into hood 411 . the airway valve 414 can be a high flow , low resistance valve . an example airway valve 414 may be a motorized butterfly valve with a data processing unit . the airway valve 414 is actuated by an electro - mechanical drive 415 and is controlled by a data processing unit 416 to allow normal , unobstructed respiration through the hood 411 when the user is not clenching . when the user is clenching , the data processing unit 416 controls the airway valve 414 via the electro - mechanical drive 415 to obstruct the user &# 39 ; s air supply partially or fully . the bruxism treatment device 300 can be powered by the physical clenching action of the user , an electrical battery pack contained within the assembly , or an external power supply . the mouthpiece 302 of fig3 and the nasal airway obstructor 400 of fig4 can be used together to form a two - piece system . when clench sensor 301 receives a signal that the user is clenching his / her jaw , a signal is sent to nasal airway obstructor 400 , which blocks air flow to the nostrils , thereby forcing the user to breathe through his / her mouth . the bruxism treatment device 300 may also include a power source . the power source may be external to the device to provide power to the device through a battery or electrical cord . alternatively , the bruxism treatment device 300 may be powered by the physical clenching action of a user . fig5 illustrates an example embodiment of a one - piece bruxism treatment device 300 . the clench sensor 301 is incorporated into the mouthpiece 302 and is connected to the nasal airway obstructor 400 via a rigid strut 501 . the rigid strut 501 is routed through the user &# 39 ; s lips to the nasal airway obstructor 400 . the bruxism treatment device 300 is anchored via the mouth piece 302 and upper teeth to the user &# 39 ; s hard palate . the rigid foundation of the hard palate allows the nasal obstructors 421 to be held via the rigid housing 502 in the correct orientation about the user &# 39 ; s nostrils . nasal obstructors 421 function by the actuation of two linear actuators that are held in the correct orientation as to collapse the user &# 39 ; s nostrils and seal - off the airway when actuated . the linear actuators can be driven by electro - mechanical drives 422 , mechanical power transmission , or fluidic power transmission ( hydraulic or pneumatic ). the rigid housing 502 of the bruxism treatment device 300 may contain a data processing unit 416 , power source ( not shown ), or other power transmission apparatus from the clench sensor 301 . other power transmission apparatuses may be mechanical or fluid . the one - piece configuration could also utilize a hood 411 , a nasal pillow type manifold ( not shown ), or any other manner of controllable nasal airway stoppers as a nasal airway obstructor 400 . other nasal airway stoppers may include a mask , a physical plug , or other similar mechanism . nasal airway obstructor 400 may be rigid , or alternatively may be pliable . these nasal airway obstructions may communication with the mouthpiece via an electrical , electromagnetic , mechanical , fluid transmission , hydraulic transmission , or other similar mechanism . the described invention may utilize data processing algorithms to control the airway obstructor in a way to best treat the user . this may include limiting the degree to which the airway is obstructed and the amount of time that the airway is obstructed . data collection is also possible for the purpose of tracking the user &# 39 ; s clenching behavior and improvement . such data may be transmittable to a computer , phone , a smart device , or other electronic device for review . in use , the mouthpiece 302 is anchored to a user &# 39 ; s upper teeth or lower teeth and the nasal airway obstructor 400 is placed over a user &# 39 ; s nasal region . when a user clenches his / her jaw , a signal is sent to the nasal airway obstructor , which blocks air flow to the nostrils of the user , forcing the user to breathe through his / her mouth . airflow to the nostrils is restored after a predetermined period of time . such a time period may be 5 seconds , 10 seconds , or up to 30 seconds . alternatively , a time period may be once the user unclenches his / her jaw . the following patents are incorporated by reference in their entireties : u . s . pat . nos . 5 , 078 , 153 ;
