The main objective of this thesis is an analysis of assessment techniques face, and cephalometric evaluation methods that are suitable for treatment of jaw position and design methods for treatment of jaw. At the same time the emphasis is on studying the methods,java advance imaging, which are used for the curvature of the image and should be able to meet the objectives of the assignment. These adjustments can be made using the Warp. Result of this work is an application developed in JAVA programming language, which demonstrates the best method for modifying the image. This method is WarpGrid. The application was made in the development environment eclipse. With this application, depending on the mouse action is possible to modify the image.

The morphology of the craniofacial complex is prone to alterations resulting from a wide range of external factors. In the first part of the presented thesis, we analysed the influence of slow long- term changes of the environment and population genome by comparing historical (11-12th century AD) and contemporary skulls using cephalometric X-ray images. The second part focuses on the effects of orthodontic treatment on bone thickness in relevant areas, with the analysis being based on Cone Beam computed tomography. A comparison of the palatal angle of 115 historical and 75 contemporary skulls revealed a statistically significant decrease of this parameter. The follow-up of 58 patients utilizing three- dimensional diagnostic imaging measurements before and after treatment revealed a statistically significant decrease in vestibular bone thickness, without changes of total alveolar width. Our analysis revealed a substantial bone response to respective forces, with relevant clinical implications - respecting the anatomical limits of the range of motion is essential to achieve therapeutic success and to avoid alveolar defects.
