Research study of total endoprosthesis of temporomandibular joint
Horňas, Jan ; Borák, Libor (referee) ; Marcián, Petr (advisor)
This bachelor’s thesis deals with total joint replacements (TJR) applied for replacement of temporomandibular joint (TMJ). In the thesis, research study of solutions system is done for anatomy of TMJ, mandible and masticatory muscles. Main producers and ma-terials for manufacturing TJR is mentioned furthermore. Finally, stress strain analysis for TJR is done by computing modeling using finite element method on the basis of re-search study.

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...

Physiotherapy as part of comprehensive treatment in patients with acquired temporomandibular joint dysfunction
NĚMCOVÁ, Barbora
The subject matter of my undergraduate thesis is acquired dysfunctionality of the temporomandibular joint. The concept incorporates a number of funcional and structural changes and pathological conditions affecting not only the mandibula as such but also the overall posture of the organism as a whole due to sequential spasms. Temporomandibular disorders have a multifactor etiology and very diverse clinical image, which often makes diagnostics quite difficult. Generally, increasing psychic tension, emotional stress, and occlusive relations are believed to count amongst the main causes. According to some studies, up to 50 % of the population suffers from some type of disorder of the temporomandibular joint. As treatment of these conditions can be problematic and time-consuming, both the pacient and the therapist have to be patient. The theoretical part of my thesis concentrates on mapping the problems arising from dysfunctionality of the temporomandibular joint, whereas the practical part contains causalistic elaboration of two female patients diagnosed with this condition. My research was conducted using the method of qualitative causalistics. The first female patient was diagnosed with degenerative changes in the right mandibular joint causing diminished mobility of the lower jaw, affecting the functionality of the patient{\crq}s right ear and body posture. The second female patient suffered functionality disorder in the form of dislocation of the mandibular joint{\crq}s disk, asymmetric movement of the jaw when opening her mouth, and irregular stereotype of breathing. In both patients, the therapy was adjusted to the diagnosis and each patient{\crq}s momentary condition. Primarily, their treatment was focused on their hypertonic muscles and sequential spasms, followed by relaxation of their chewing muscles, training of symmetrical mouth opening, breathing stereotypes, and sensomotoric elements. The patients were instructed how to do suitable autotherapeutic exercises. The therapeutic sessions took place twice a week over a six-week period. In both patients, the results were satisfactory. With the first patient, her ability to open her mouth and her overall posture improved. With the second patient, the unpleasant noise phenomenon when opening her mouth was removed and the asymmetry of mouth movement was diminished. Moreover, she learned to adopt a regular breathing stereotype. My thesis can be useful in the clinical practice of physiotherapists, physicians, and other medical personnel, as well as a source of information for patients.
