Stress-strain analysis of dental implant inserted in maxilla
Dušková, Tereza ; Hájek, Petr (referee) ; Marcián, Petr (advisor)
Variety of problems can appear when introducing dental implants, especially to in the maxilla. Biggest problems are caused by insufficient quality and volume of the bone tissue of the alveolar process. This thesis focuses on stress-strain analysis of an implant introduced in the maxilla. Mechanical interaction between the implant and bone tissue is solved using computational modelling with the finite element method. From analysis of results, it was discovered that deformation and tension of the implant are influenced by the direction of the load, osseointegration and thickness of the cortical bone tissue. In the anterior region, it is necessary to work with other types of load than axial.

Proposal and Implementation of Production of Dental Plate Construction
Dusbaba, Michal ; Chladil, Josef (referee) ; Sedlák, Josef (advisor)
This thesis deals with a CAD programmed construction design of dental prosthetics and its subsequent production by means of a five axis machine tool. In the theoretical part of the thesis one can find characteristics and analysis of materials designed for a production of dental prosthetics constructions. Among other things, the practical part of the thesis follows up digitization of a patient´s oral cavity part with the use of Trios intraoral scanner representing the latest scanning technology. The obtained data created a basis for a design of the respective dental prosthetics construction using the shape dental system programme called DentalDesigner 2015. Furthermore, the paper deals with a production of a dental prosthetics construction by means of a five axis machine tool and pursues completion works which resulted in the prosthetics final shape. The paper is concluded with discussion comprising a summary of results acquired in the practical part beginning from dental implant introduction to insertion of the made prosthetics construction into the patient´s oral cavity.

Biomechanical analysis of bone implant contact for different type of implant profiles
Svobodová, Miriam ; Chamrad, Jakub (referee) ; Marcián, Petr (advisor)
This bachelor thesis deals with the assessment of the influence of the dental implant diameter placed in the bone with a fixed connection between the bone and the given implant on the strain into the bones around the implant,the deformation throughout the system and the stress in the implant. Computational modeling with finite element analysis was used to solve a given task. Two types of the implants with different diameters and bone model with a beam structure and different layer thickness around the implant were modeled. Used material was homogeneous, isotropic and linearly flexible. The overall analysis was carried out at the 2D level. The results show different values for different diameters and thickness of the layers.

Stress strain analysis of dental implant
Snášelová, Dana ; Florian, Zdeněk (referee) ; Marcián, Petr (advisor)
This bachelor thesis deals with stress strain conditions at interface of dental implant and bone of mandible in two-dimensional space. To solve these proportions the finite element method was used. Solution was realized in finite element software Ansys Workbench 15. This thesis also offers comparsion between different samples, which vary in bone density and type of dental implant.

Biomechanical research study of maxillary dental implants
Navrátilová, Jana ; Borák, Libor (referee) ; Marcián, Petr (advisor)
This bachelor thesis deals with a literature search on theme dental implants in maxilla. Maxilla is a specific area because of its bone tissue quality and the amount of space for applying implant. The thesis presents possible complications during implation in maxilla and augmentation opportunities. Further stress-strain analysis of maxilla with dental implant was made. For solving the problem the computational modeling by using Finite Element Method was used.

Analysis of dental implants in the context of current standards
Šlajs, Ondřej ; Hájek, Petr (referee) ; Marcián, Petr (advisor)
Presented bachelor thesis focuses on geometry production of dental implants from real samples and their stress-strain analysis all in the context of the current standards. In the first part of the thesis research ranging from the basic anatomy to the geometry of implant threads is presented. In the next part, the current standards applicable to dental implants are presented and explained. The last part is focused on the description of the geometry of studied implants and their stress-strain behavior. All this is in context with valid standards.

Stress-strain analysis of dental implant inserted in different mandibles
Diakovová, Tereza ; Thomková, Barbora (referee) ; Marcián, Petr (advisor)
This thesis deals with a problem in the field of dental implantology, namely the mechanical interaction between the dental implant and the bone tissue of the mandible. This interaction is affected by the shape and density of the bone tissues. A review of studies dealing with mechanical stresses at the bone-implant interface is carried out. The obtained information were further used in the analysis of bone tissue density and in the strain-stress analysis of three geometrically different jaws with an implant placed in the first molar region. Bone density was evaluated based on information obtained from CT scans of the individual jaws. For evaluation of the deformation-stress states was used computational modelling using the finite element method. Three models of jaw geometries were created based on CT images. The implant was loaded from masticatory forces at the moment of bite. Based on the results, it can be stated that the shape and thickness of the cortical bone tissue and the density of spongiosis have a significant influence on the deformation-stress states of the bone-implant interface.

System to support decision making in dental implantology - quality of life of patients with dental implants
Kříž, Pavel ; Dostálová, Taťjana (advisor) ; Mazánek, Jiří (referee) ; Zvárová, Jana (referee)
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...
