Stress - strain analysis of jaw with decrease bone tissue
Krpalek, David ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This diploma thesis deals with stress - strain analysis of jaw with decrease of bone tis-sue. At first was created a model of geometry using graphic program Rhinoceros 4.0 upon acquisition by the 3D scanner. That was converted to the computational system ANSYS Workbench 11 which uses for solving the finite element method (FEM). Solving was executed with homogenous, linear and isotropic material model of bone with different characteristics for compact and cancellous bone. Forces of the three working muscles, which participate on chewing, were given on the basis of the force and moment balance mandible. Solving was executed for 12 variant simulating occlusion in places, where was earlier found teeth.

Stress - strain analysis of jaw with tooth implant type BOI
Marcián, Petr ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
Submitted master thesis deals with stress - strain analysis of jaw, with dental implant. The implant serve as a suitable pillar for crown or dental bridge, when one or more teeth are lost. The project is oriented on BOI (basale - oseo - integrable) dental implant type, which is produced by DENTALIHDE company. Stress – strain condition of the mandible system with implant have been established by computational simulation, with use of the final elements method. Important part of down jowl is simulated on with EDS and EDDS applied types of implants. After implementation the implant begins to heal. Therefore the special attention is paid to stress - strain states on various level of osteointegration. There is a detail description of production of single part computational model and his solving in the master thesis. Presentation of large chapter with results and subsequent alteration stress - strain analysis is part of the master thesis. Program SolidWorks 2005 was used to create the geometric model. Computational model and the actual solving was accomplished with use of ANSYS 11.0 and ANSYS Wor-kbench systems.

Tooth Detection on Jaw 3D Computer Polygonal Model
Hulík, Rostislav ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
This document discusses a concept and implementation of algorithms for teeth detection on 3D polygonal jaw model. At first, I describe possible shape detection techniques on three dimensional computer model, including utilization just in my case. After it, I analyze filtration problems of obtained model segments in order to reliably separate regions of tooth-arch from the rest of jaw. I included all these pieces of knowledge into a final application. Here, it is possible to choose from two user interfaces, first, classic user interface which demonstrates possible utilization in real world and second, testing interface which demonstrates functions of each detection and filtration method used in program and their effect on detection. Application is written in C++ language in development environment of MS Visual Studio 2005 and compiled with MS VS internal compiler. Tested was under MS Windows XP and MS Windows Vista OS.

Stress - strain analysis of jaw with tooth implant type MTI
Petrlíková, Helena ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This diploma work is oriented on the deformation and load stress analysis of the jawbone with the razor-blade dental implant of the company MTI. There is a literature search on this theme in the beginning of this work. Deformation and tenseness of the system is done by computerized method FEM. There is detailed description of creating the computational model in this work. The geometry model of the system was created in the 3D CAD design software SolidWorks. Discretization, model of constrains and load sets including own solution was created in the ANSYS Workbench. On the basis of solutions with different load sets, which are presented in this work, is created a deformation and load stress analysis for two razorblade implant of copany MTI.

Stress - strain analysis of jaw with tooth implant
Hamerníková, Martina ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
This diploma thesis is oriented on a stress – strain analysis of the jaw bone with a screw dental implant. There is a literature search on this theme in the beginning of this work. Solutions deformation and stress the system lower jaw and implant was performed computational modeling, by using the finite element method. Modeling is part of the lower jaw with dental implants applied screw type Ankylos, Bränemark and implant with metric thread. The thesis is described in detail development of calculation model system and solutions. To create a geometry model of geometry Solidworks 2007 was used. To create calculation model and the solution was implamented in the computer systém ANSYS 11.0 and ANSYS Workbench.
