Bruxism and GrindCare Treatment.
Bruxism represents one of the largest concerns in Dentistry today and so by offering patients who suffer from bruxism the GrindCare treatment option Dental Clinics can significantly improve the quality of patients overall wellbeing, while simultaneously improving their dental health.
What does bruxism mean: Bruxism (from Greek: brychein): Involuntary gnashing, grinding.
Epidemiology: The estimates of prevalence depend on how bruxism is defined and assessed. However, self reporting of sleep bruxism is: 14% to 18% in children. 8% to 10% in Adults. 3% in older people. The prevalence of awake bruxism is reported to be 20% among the adult population.
Etiology: SB as well as awake bruxism occurs in most people and in some people causes signs and symptoms. No single causative factor for sleep bruxism (SB) or awake bruxism is found. Factors contributing to the regulation of bruxism include: Genetic disposition, Anxiety or stress, Neurotransmitter levels, smoking and alcohol.
Patophysiology: Sleep bruxism is believed to be centrally mediated under the influence of the autonomic system function and brain arousal. Most SB episodes are detected during light non-rapid eye movement (non-REM) sleep (sleep stage 1 and II). Less than <10% of sleep bruxism episodes occur during REM sleep.
Awake bruxism may be a stereotype reaction to external stimuli such as mental or physical stress.
Signs and Symptoms of Bruxism, include muscle contraction headaches, destruction of dental work, tooth wear, tooth abrasion, alveolar bone loss, malocclusion, cracked teeth, muscle hypertrophy, myofacial pain, degenerative joint disease, clicking, periodontal breakdown and joint pain. Plus disturbance of bed partners sleep and reduction of overall quality of life.
Bruxism factors:
Tooth wear is the most frequently observed complication in bruxism.
Jaw-Muscle pain: awake bruxism appears to be a significant risk factor for jaw-muscle pain. Regarding sleep bruxism, there is a non-linear correlation between jaw muscle activity and pain.
Temporo-Mandibular Disorder: Chronic bruxism can cause TMD symptoms such as Myofacial pain and disfunction, internal joint derangement and osteoarthritis.
Muscle hypertrophy: may cause a cosmetic complication for some individuals. It is likely to be reversible, if the jaw muscles become less active.
Tension Headache: is the most common of the primary headache types. Up to 55% of tension-type headache patients and migraine patients are believed to show signs and symptoms of TMD.
GrindCare Treatment and Bruxism.
GrindCare is a medical device intended for monitoring and the treatment of Bruxism. It is an easy to use electronic device that patients can wear during the night. It is used to disrupt the bruxism reflex. The impulses reflectorically induce relaxation of the masseter and temporalis during sleep without wakening the patient.
The device consists of three main components:
#1 A Stimulator which is for the measurement of EMG signals during sleep, analysis of EMF signals with algorithm and the emission of a contingent electrical stimulation.
#2 A Grinddock, which is a remote control for the stimulator. It provides a wireless (radiofrequency) communication for transferring patient data to a PC and it is also used to re-charge the battery of the stimulator.
#3 A two-way electrode which is placed on the temporalis muscle (using a gel pad). It is used for reading the EMG signal and sending the electrical impulse.
GrindCare records electromyographic (EMG) signals from the muscles. EMG signals are generated when muscle fibres are active- due to currents flowing in and out across the cell membrane of each individual muscle fibre. The EMG activity level (amplitude) is set to a comfortable threshold value to detect a patients grind. The threshold is set during the set up and calibration of the device for each patient and recorded by asking the patient to relax, grimace and finally clenching. GrindCare uses this information to calculate a comfortable threshold and activate the stimuli.
Patients who have suffered from bruxism and woken in the morning with headaches, sore jaws, sore teeth, sore muscles and a lack of sleep can now use GrindCare as a treatment option. And of course the considerable reduction in the need for medication is both health and finacially beneficial.
