Description

DEVICE FOR MONITORING AND DECREASING THE DISORDER OF THE

BRUXISM

FIELD OF THE INVENTION

[0001] The present invention relates to the relief of bruxism. In particular, the present invention relates to a device that comprises at least four components and is used for the detection, monitoring and correction of bruxism.

BACKGROUND OF THE INVENTION

[0002] One of the problems that in recent decades has severely disrupted active society and that is the result of constant stress experimentation, in the different roles in which the individual develops, is the "bruxism" disorder. . This disorder is identified by an exacerbated amount of contractions and grinding of teeth that manifest mainly during sleep. Although stress can be represented in multifactorial ways, it has been studied and there is evidence that a large part of the population experiences movement disorder in the masticatory system as a nocturnal or waking manifestation, which is shown by increasing non-functional muscle activity. in the area, which results in painful alterations in the craniocervical-mandibular area, where the temporomandibular joints are located. The most common disorders of nocturnal bruxism are earaches, cracking in chewing, headaches, wear or tearing of dentures, difficulty or tiredness when chewing hard foods, as well as a new disease known as tinnitus, characterized by perception of a continuous and permanent sound (buzzing) in the individual.

[0003] Scientific studies carried out, and especially in the study entitled "Rhythmic Masticatory Activity During Sleep" by researchers Lavigne, Rompré, Poirier, Huard, Kato and Montplaisir, published in the Journal of Dental Research in 2001 (GJ Lavigne, PH Rompré, G. Poirier, H. Huard, T. Kato, JY Montplaisir, “Rhythmic Masticatory Muscle Activity during Sleep in Humans, ”J. Dent. Res., (2001), Vol. 80, Issue 2, pp. 443 ^ 148 https://doi.org/10.1177/00220345010800020801), notes that a large number of the population (60%) present what is known as a rhythmic masticatory muscle activity (RMMA) at a frequency of 1.7 episodes per hour of sleep. In contrast, the presence of sleep bruxism is characterized by repetitive (physical) or sustained (tonic) muscle contractions occurring at a greater frequency of 5.4 episodes per hour at an intensity of 30% to 40% higher with respect to the RMMA of normal subjects .

[0004] Different ways of alleviating bruxism disorder have been reported in the state of the art.

[0005] Document DE3635188 A1 discloses an apparatus for recording e) night grinding for diagnostic and therapeutic purposes. However, this document only mentions the recording of muscle contraction externally and fails to disclose the oral guard, the actuator element and the smart device.

[0006] Document KR2010113296A discloses a device and a method for preventing bruxism by applying a stimulus to a body through the control of a stimulus device containing a bruxism sound signal processor, a simulator device controller, a simulator device, a bruxism signal storage unit and a stimulus device controller intensity signal and the output level value of the bruxism sound signal processor. However, the document fails to describe the temperature change emitted by the actuator element and does not contemplate the emission of sound (music) between 4 and 7.5 Hz for the same purpose of relaxation.

[0007] Document KR2012093474A mentions a method for providing a bruxism relief service using electrical stimulation, a recording means thereof, a bruxism sensor device and a portable device. However, it fails to describe that an external actuator element can produce heat and emit music for user relaxation. [0008] NL1014436C1 communicates an apparatus for detecting and emitting an alarm to minimize the grinding of teeth during sleep, which consists of a microphone, an amplifier, a signal filter, a signal rectifier; in said apparatus, if the signal exceeds a reference level, a generator emits an alarm signal to wake the sleeper. Document US9398974B1 discloses a bruxism sensor, which includes a diaphragm switch, an audible alarm and a hose, both documents fail at least, in disclosing the temperature change emitted by the actuator element is intended to relax the user without having to wake him up In addition, it does not include the emission of sound (music) between 4 and 7.5 Hz for the same purpose of relaxation. Additionally they do not mention the possibility of monitoring activity during sleep.

[0009] Documents US4838283A and US4989616A publish an apparatus and method for controlling and preventing bruxism comprising a sound generating means, a sound reception means, both fixed on the user's face and an electronic control means for receiving signals from said sound receiver which activates an alarm when bruxism occurs. However, although in this case it is not necessary for the user to wake up to relax it, this document does not disclose the temperature change characteristic that the actuator element emits nor does it contemplate the emission of sound (music) between 4 and 7.5 Hz with The purpose of user relaxation. Additionally they do not mention the possibility of monitoring activity during sleep.

[0010] Document US5190051A discloses a dental guard to audibly indicate the onset of tooth clenching and thus help the user to alter the habit patterns that constitute bruxism. The device does not communicate with an actuator element or an intelligent device nor does it emit heat or music as described in the present invention.

[0011] US5586562A discloses a device and method for the treatment of bruxism, snoring and sleep apnea that includes a dental protector that has a pressure sensitive surface that is coupled to an alarm mechanism. The alarm provides a resonant frequency capable of emitting a sound or a vibration to alert the individual that the bruxism Said document, although it mentions a dental protector equipped with a sensitive surface (sensor), fails to at least disclose the monitoring, nor the communication with an intelligent device.

[0012] US8226569B2 provides a method for managing a patient who has a sleep disorder. The method comprises controlling the physiological information of the patient and converting it into digital data, storing the digital data, identifying, characterizing the digital information and storing the information in a digital memory. However, it does not disclose the actuator element that relaxes the subject by emitting heat, cold or music or communication with an intelligent device.

[0013] Document CN203458385U discloses a wireless electronic device to help an individual stop snoring and prevent bruxism which comprises a snoring cessation device and an intelligent terminal system that communicates wirelessly; the device for stopping snoring has a controller module and an electric pulse emission / vibration module, a wireless transmission module, a power supply module and a light sensor module that are respectively connected to the controller module; the recording function module is used to acquire abnormal sleep sounds; However, this document does not communicate, at least, the mouth guard or the transmission of heat or music, as well as the possibility of subsequently assessing the behavior during sleep in order to correct it.

[0014] CN201968868U refers to a therapeutic biofeedback bruxism apparatus, comprising a bite plate and a bruxism monitor which measures and records the precise data of bruxism time and bruxism frequency. The device stimulates various types of activation or fast music and vibration, so that patients can consciously stop behaviors. In addition, according to the data recorded at different times, an effect of the treatment of the therapeutic apparatus on bruxism is evaluated. However, it fails to describe the heat emission of the actuator element and to mention that it activates music that contains a frequency range between 4 and 7.5 Hz to relax the user when the established limits of pressure, frequency, duration and intensity are exceeded

[0015] The invention described in FR2618327A1 relates to a device that, by issuing an audible stimulus, allows the uncontrolled contraction of the masseter to be interrupted. The device consists of a sound or vibration emission sensor generated by teeth grinding, a band filter and a preamp module that is connected to an amplification module. However, the invention does not show a mouth guard, real-time monitoring, the possibility of evaluating monitored data or communication via remote with an intelligent device.

[0016] US4715367A discloses a multifunctional behavior modification device to diagnose, treat and control the treatment of snoring, bruxism or sleep apnea, and which consists of an aversive adjustable shock; said document fails to describe the actuator element that emits heat, the emission of sound, the oral guard, communication with the smart device and data monitoring.

[0017] According to these references, there is a need to overcome the deficiencies of the state of the art, so it is proposed to inventively combine some of the techniques traditionally used to reduce bruxism disorders, as well as the incorporation of new technologies invasive to guarantee the quality of sleep, relaxation and productive capacity of! individual.

[0018] With regard to the signal system for the detection of bruxism, oral protection devices now incorporate mechanisms to an electronic package adapted to detachably join a dental device. The dental appliance can be configured to be secured inside the user's mouth and the electronic parts come with an extension to be able to adapt them externally to the user's mouth and thus connect it to the dental appliance (US2016 / 0095740).

[0019] Other inventions provide portable devices and techniques for monitoring bruxism or sleep apnea related to bruxism. (US2013 / 0253286). These techniques provide a customized tooth guard and jaws that are configured to be attached to at least some of the teeth, both in the upper jaw and in the lower jaw according to the predetermined resistance of grinding the teeth in the positions. . Although the grinding of the teeth is reduced, it can be seen that the device can generate additional efforts and subsequently cause jaw pain.

[0020] To lessen the impact and wear of the teeth, some inventions propose the use of a dental device designed to protect the teeth against injuries from impacts suffered in sports or other activities that can cause chipping, fracturing, eviction or complete loss of the dental piece The apparatus can be adapted as at least one cavity has an energy absorption fluid. The energy absorbing fluid should be nanosuspensions of small particles in viscous fluids that can undergo shear thickening when the dental object hits the dental apparatus (US2015 / 0328526). The device dampens and diffuses horizontal and axial forces and moves them away from teething, thus reducing the risk of dental injuries. Within these devices for treatment is a haptic feedback device, which contains a pressure sensor that activates a vibration when a pressure is recorded above the programmed threshold.

BRIEF DESCRIPTION PE THE INVENTION

[0021] The proposed device monitors the frequency, duration and intensity of the pressure that is recorded in the molar denture during the subject's sleep, that is, when he experiences night bruxism, where this information is processed to take measures of action immediately (by the device) and later (by the user).

[0022] The device consists of three components. The first comprises the part that is in internal contact with the user (guard), which activates and sends the signals when the internal pressure sensor records the molar pressure by the user; the second component registers this signal, and sends it to two means of action, third, a) a band that is placed by the back of the user and its terminations at both ends of the face have external contact with the temporal and masseter muscles where a source of propagated heat is emitted through gel that covers the device, and b) to the activation of an application of an intelligent device equipped with bluetooth that activates music that contains a frequency range between 4 and 7.5 Hz to relax the user.

[0023] The term "guard" is understood as any occlusal attachment that is located between the jaws (upper jaw, lower or both).

[0024] Because the problem of nocturnal bruxism is of a multifactorial nature !, there is no single solution that allows to eradicate the problem, therefore, what is planned with this device, is to contribute significantly to the monitoring and correction of the suffering from night bruxism. That is why, the device is able to detect the initial presence, frequency, time and intensity, and with these conditions the device, without interrupting the user's sleep, is that it exerts action criteria to help relaxation and decrease future User jaw headache disorders upon waking.

[0025] The disorder of nocturnal bruxism, has several scenarios that suggest its appearance, among which the psychological also stands out, that is why this device stores the information with which the user can know their levels of intensity, frequency and time, and thus take measures that help you decrease and see your progress.

[0026] The particular characteristics of the product are that it captures the frequency, duration and intensity of the RMMA during sleep, and when it exceeds the established limits, the response to prevention will be the transmission of the Theta brain wave ranges (4 a 7.5 Hz), combined with the external activation of propagation of heat and cold cycles in the areas corresponding to the temporal and masseter muscles.
