Stress-Strain Analysis of Total Endoprosthesis of Temporomandibular Joint
Horňas, Jan ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
The presented master’s thesis deals with the problem of the application of total endoprosthesis (TEP) during temporomandibular joint (TMJ) replacement. The implantation of TEP occurs due the severe TMJ disease (arthrosis, ankylosis, cancer) or its macrotrauma. Condylar prosthesis is fixed during the implantation by self-tapping screws to the mandible. This fixation causes a change of stress-strain behaviour of mandible, TEP and fixation screws. In the thesis is performed the stress-strain analysis by using computational modeling in use the finite element method (FEM). Analysis is performed for six different screws positions (the number of screws is unchanged) and for a variable the static friction coefficient (in range 0.1 to 0.11) between condylar prosthesis (CP) and fossa prosthesis (FP). Altogether, 36 variants of computational models were created. The stress strain analysis detected a substantial influence of the static friction coefficient value to final results of displacements, contact pressure on the articulation surface between the CP and the FP and also to von Mises stress of the CP. A substantial influence of different screws position is detected for von Mises stress in the screws and for von Mises strain in the cortical and spongious bone tissue.

Mičánková, Kateřina ; Šedý, Jiří (advisor) ; Kachlík, David (referee)
This thesis focuses on the comparison of results of dental and kinesiological examination, medical history, PHQ-4 questionnaires and X-rays between a group with symptoms of temporomandibular disorder and an asymptomatic group. The theoretical part summarizes anatomy and kinesiology of the temporomandibular joint and also epidemiology, etiology, symptomatology, classification, examination and treatment of temporomandibular disorders. The main goal was to compare differences between the two groups in muscle tenderness or pain on palpation, range of active depression of the mandible and active dorsiflexion of the cervical spine. Methods: A total of 30 patients were included in the study, out of which 18 were in the symptomatic group (mean age 44.8, SD ± 11.6 years) and 12 in the control group (mean age 36.9, SD ± 13.9 years). The participants underwent a clinical examination, which consisted of thorough collection of medical history, dental and kinesiological examination and X-rays (anteroposterior, lateral, panoramic), the participant also filled in the PHQ-4 questionnaire. Results: Muscle tenderness or pain on palpation in the symptomatic group was significant (p = 0.019). There was not a significant difference in depression of the mandible between the groups (p = 0.26). Range of active dorsiflexion...

Možnosti fyzioterapie u bolestí hlavy vertebrogenního původu
FRIDRICHOVSKÝ, Radek
This bachelor thesis deals with the possibilities of physiotherapeutic intervetion of headaches of vertebrogenic etiology. The therapy of all patients is based off of the same principle and a similar approach resp. manual treatment of overworked and shortened muscles, adjusting the breathing stereotype, correcting basic movement stereotypes, engaging of the deep stabilisation system through picked exercises and exercising autotherapy given to the patient. The thesis is divided into two parts. The theoretical part is focused on anatomical structures related to the issue, following is the clinical picture and differential diagnosis of headaches, prevalence and possibilities of physiotherapy. Practical part is comprised of the exercise unit, made using the methods from the theoretical part, and the actual research, processed in the qualitative form, containing the entry and final kinesiological examination alongside the course of therapy of three female patients of similar age. Based on the entry kinesiological examination each patient had their exercise unit tailored for them, which the patient was instructed to exercise three times a week. The research was planned for two months, with two out of three patients having the total of 8 sessions, the first patient was unable to attend two therapies due to COVID-19 infection. There is a summary and the achieved effect described at the end of each case study. Next i focus on discussion, in which i summarize the aspects of the theoretical part with the results of the practical part, i also include a few recent publications focused on headaches and way of treating them. The thesis is finished with a summary and a list of used sources.

Possibilities of physiotherapy for patiens with migraine headache.
POLANOVÁ, Edita
This bachelor thesis deals with the possibilities of physiotherapy for patients with migraine headache. With accurate selected physiotherapy, patients have a reduction in the number of migraines and the pain during the attack decreases its intensity. Therapy for all patients is uniform in this work. Physiotherapy emphasizes improving the function of the respiratory system, reducing the tension of hypertonic muscles, stretching the muscles in the area of the AO junction, increasing the extension of the temporomandibular joint, increasing the extent in the cervical spine and relaxing the fascia of the head. The first goal of the work is to map the possibilities of physiotherapy for patients with migraine headaches. The second goal is to design exercises and create an exercise unit suitable for autotherapy for patients with migraine headache. The third goal of the work is to create educational material for patients with migraines. The work is divided into 2 parts. The theoretical part describes the disease (pathophysiology, clinical picture, disease diagnosis, differential diagnosis, complications, prevalence, treatment options, the impact on the patient in society and the possibilities of migraine physiotherapy). The second, practical part, is processed in the form of qualitative research and includes kinesiological examination and therapy of 6 women aged 23-46 years. Patients were informed about the therapy and that information about the results will be published in this work in the form of informed consent. After the initial examination, a physiotherapy unit was designed for the probands. To confirm the appropriately selected therapy, 10 therapies were performed with each patient and the patients were monitored for 6 months. Furthermore, the final kinesiological analysis and evaluation of therapy for each patient were written. The conclusion of the thesis contains the results of the research. The work can be used in clinical practice by a physiotherapist or as an educational material for patients with migraine headaches.

Influence of the occlusal plane inclination on the functional condition of the orofacial region .
Yurchenko, Maksim ; Hubálková, Hana (advisor) ; Németh, Tibor (referee) ; Jenča, Andrej (referee)
The functioning of maxillofacial complex as a one unit is an important condition of fulfilling several functions connected with this area of human body. A maxillofacial region and other parts of the body are connected through occlusion, one of the basic characteristics of which is occlusal plane. According to the number of researchers, 3D orientation of occlusal plane, its shape and possible deformation can have an influence on other anatomic structures via a system of a complex neuromuscular reactions. This theory assumes that the adjustment of occlusal plane inclination causes redistribution and redirection of the chewing forces in the adjacent structures which will subsequently manifest itself in the adjustment of the tension of different muscles. Aim The aim of an experimental part of the research was to define the influence of occlusal plane inclination on the function of maxillofacial region with the focus of jaw joints and chewing muscles. The next goal was to determine the figures of sagittal and frontal inclination of occlusal plane which can be considered as physiological. Patients and Methods The research was based on the examination of 87 people of both genders, different age groups with a complete set of teeth and without chronic diseases. The participants were divided in two groups...
