Filter by:The aim of this study is to investigate the potential effects of different jaw relation determination (KRB) techniques on the fabrication of Michigan splints, in particular by comparing conventional methods with a wax plate and the use of an anterior jig. All materials and methods for the fabrication of the Michigan splint are already part of the curriculum of the Clinic for Dental Prosthodontics for first-year Master-students. Therefore, we intend to conduct a retrospective study (for the 2023 cohort) and a prospective analysis of the data (for the 2024 and 2025 cohorts). Questionnaires, models and intraoral scans will be used to evaluate the efficacy and precision of the different KRB methods as well as the fabrication process of the Michigan splint.
Sleep disordered breathing is a common and serious health problem. According to epidemiological data, it may affect about 20% of adult population. The majority is not aware of the disease. The most common sleep disorder is obstructive sleep apnea (OSA). The essence of OSA are the episodes of airway obstruction repeated many times during sleep, as a result of which the level of partial oxygen in the blood decreases. Apnea episodes end up waking from sleep, causing sleep fragmentation, deep sleep and REM deficiency. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. Comorbid Insomnia and Sleep Apnea (COMISA) is a highly prevalent and debilitating disorder that causes additional disturbances in sleep, daytime functioning, and quality of life for patients, and is a significant diagnostic and therapeutic problem for clinicians. Although the presence of COMISA was first noticed by Christian Guilleminault and his colleagues in 1973, it received very little research attention for almost three decades. There is still lack ofclinical trials concerning this topic. An additional problem in apnea patients is the increased incidence of bruxism. Bruxism is associated with increased masticatory muscle activity during sleep, which may be phased or tonic. It is estimated that the incidence of bruxism in the adult population is 13%. The most common symptoms of bruxism include: pathological wear and tooth sensitivity, damage to the periodontium and oral mucosa, muscle pain in the stomatognathic system, headaches and damage to prosthetic restorations. However, the symptoms of bruxism can go unnoticed for a long time, leaving patients often unaware of the problem. The aim of this project is: 1. to determine the prevalence of sleep bruxism in COMISA, OSA and insomnia, 2. to examine of arousals (type, frequency) in COMISA, OSA and insomnia, 3. to investigate the relationship between arousals and blood pressure values and variability, arrhythmias, sinus rhythm variability, vascular endothelial dysfunction, cardiovascular risk in COMISA, OSA and insomnia.
Bruxism is a common phenomenon. It is estimated that its prevalence in the adult population is 8-31%. Bruxism occurring during sleep is the activity of the masticatory muscles that appear during sleep, which can be rhythmic or phased and is not a movement disorder or sleep disorder in healthy people. It is currently believed that bruxism should not be considered a disorder. In healthy people, it is treated rather as behavior, which may be a risk factor for pathological clinical implications or a protective factor in the presence of other disease entities. The most common symptoms of bruxism include: pathological wear and tooth sensitivity, periodontal and oral mucosa damage, myalgia in the stomatognathic system, headache and prosthetic restoration damage. However, due to nocturnal occurrence, bruxism symptoms may go unnoticed for a long time, which means that patients are often unaware of this behavior. The etiology of bruxism is multifactorial and not fully understood. It is currently believed that it can be caused by genetic, psychological and exogenous factors. Due to the unclear etiology of bruxism, it is so important to conduct research that allows making a certain diagnosis and finding the causes of this phenomenon
Sleep apnea is a common and serious health problem in the Polish population. According to epidemiological data problem concerns about 7% of the adult population. The most common sleep disorder is obstructive sleep apnea (OSA). The consequence of episodes of airway obstruction and sleep fragmentation is an inefficient sleep, pathological daytime sleepiness, falling asleep involuntarily, awakening with feelings of shortness of breath or throttling. The direct consequences of sleep apnea are hypoxia, increased heart rate and increased blood pressure. Frequent complications of OSA are hypertension, stroke, cardiac arrhythmia, coronary artery disease and pulmonary hypertension. An additional problem in patients with sleep apnea is an increased incidence of bruxism. Bruxism is a common problem; reports of prevalence range from 8-31% in the general population. The most common symptoms of bruxism include: hypersensitive teeth, tooth wear, damage to dental restorations (e.g. crowns and fillings), damage to periodontal and oral mucosa, masticatory muscle pain and headaches. The etiology of bruxism is multifactorial and not fully understood. It can be caused by biologic, psychologic and exogenous factors. Arousals during the apnea episodes are considered to be a major cause of sleep bruxism in OSA patients. The relationship between OSA and sleep bruxism is still not clearly defined. Further research is needed to help explain the relationship between these two phenomena, which will enable further therapy in patients with coexisting OSA and sleep bruxism (SB).
In this study it is to be evaluated wether a restoration with composite resin fillings to reestablish a canine guidance will reduce masticatory muscle activity in patients with bruxism.
