Title: System to support decission making in dental implantology - quality of life of patients with dental implants Author: MUDr. Pavel Kříž Department: Paediatric Stomatology of 2nd Medical School and Faculty Hospital Motol, V Úvalu 84, 150 06 Prague 5 Supervisor: Prof. MUDr. Taťjana Dostálová, DrSc., MBA Supervisor's e-mail: tatjana.dostalova@fnmotol.cz Dental implants are the method of choice in the treatment of missing tooth/teeth replacement. Implant therapy must be preceded by a detailed examination and the overall treatment plan. As an aid for decision-making for dentists was created decision-making scheme, which gradually, logically and schematically guides the dentists in this particular situation. Health is closely related to the quality of life. Our work evaluates the oral health-related quality of life (OHRQoL) of patients with dental implants. The aim of our study was to determine whether treatment with a dental implant(s) improve(s) OHRQoL. We created a questionnaire to determine the quality of life before and after implantation. In our study, we evaluated only patients who were treated by the only one implantological system to eliminate the influence of other systems on the quality of the results of the study; we evaluated a total of 297 implants. It was assessed a total of 97...

Evaluation of the stability of osteosynthesis of mandibular ramus sagittal split osteotomy
Nieblerová, Jiřina ; Mazánek, Jiří (advisor) ; Dostálová, Taťjána (referee) ; Bulík, Oliver (referee)
Orthognatic surgery deals with congenital and acquired dentoalveolar or skeletal deformities of the face. An unfavourable downward rotation of a mandible and posterior vertical maxillary excess cause an anterior open bite, which is characterized by excessive anterior facial height in the lower third, a gap between the incisors in maximal occlusion and a large mandibular angle. Osteotomy (mainly Le Fort I osteotomy or bilateral sagittal split osteotomy of the mandibular ramus - BSSO), ostectomy or distraction osteogenesis are performed to correct the orthognatic deformities. Osteosynthetic materials based on titanium or bioresorbable materials are used in the form of miniplates with monocortical screws, or bicortical screws are utilized to fix the bony fragments. Stability of the new jaws position is the main criterion for success. Relapse causes a loss of occlusion and consequently functional and aesthetic disorders. Relapse consists of skeletal and dental factors. Skeletal relapse is usually divided into early and long-term relapse. BSSO with counter-clockwise (CCW) rotation of the occlusal plane alone was traditionally considered to be the least stable treatment method. Some authors suggest the use of two miniplates on each side of the osteotomy, but we have not found scientific proof of the...

Overview of imaging methods used in dentistry and their availability in Prague
Vávra, Michal ; Mazánek, Jiří (advisor) ; Hořejš, Josef (referee)
This work tries to compare the availability of intraoral and panoramic X-rays in dental offices in Prague with the situation in the rest of the Czech Republic. With the help of the questionnaire examines in detail the sixty randomly selected dentistry in Prague, whether they are owners of the intraoral or panoramic X-rays in their practice, how many registered patients they have and which technical devices they use are using to diagnose dental caries. The first hypothesis was confirmed. In Prague, on average, are more radiological devices per patient and the imaging methods are more available. The second speculation about the use of bite-wing projection and other methods to diagnose early carious lesions was not confirmed. Of those sixty respondents, only 12 percent of dentists admitted to use this methods.

In the thesis the author deals with the surgical technique of the genioglossus advancement and hyoid myotomy (GAHM) in the obstructive sleep apnoea syndrome (OSAS) therapy. He focuses in particular on methods used to widen the upper airway by surgical modification of facial bones. Following the definition of the research objective in Chapter 1 and the general introduction in Chapter 2, we can find in Chapter 3 the description and definition of OSAS as well as physiological, pathophysiological and epidemiological notes on sleep, ventilation in sleep and OSAS. In Chapter 4 the author recommends some new methods of examining the upper airway that can be applied in an ordinary dental surgery to predict the risk of development or occurrence of OSAS in some patients. Chapter 5 includes an overview of therapeutic options for OSAS and a detailed description of different GAHM techniques. In accordance with the research objectives and the methodology described in Chapter 6, the results in Chapter 7 show, for a large sample of examined patients, the dependence of obesity (as expressed by the BMI) on the severity of OSAS, along with some cephalometric values in which such dependence has not been published so far. Then the chapter documents a high success rate of GAHM treatment of OSAS in operated patients. This is so,...
