Influence of the method of TM joint total replacement implantation on the loading of the joint on the opposite side.

The temporomandibular (TM) joint is one of the most used joints in the human body, and any defect in this joint has a significant influence on quality of life. The objective of this study was to create a parametric numerical finite element (FE) analysis to compare the effect of surgical techniques used for total TM joint replacement implantation on loading the TM joint on the other side. Our hypothesis is that for the optimal function of all total TM joint replacements used in clinical practice it is crucial to devise a minimally invasive surgical technique, whereby there is minimum resection of masticatory muscles.

Individual replacement of the frontal bone defect: case report.

The objective of the skeletal defects reconstruction using individual implants is an attempt to replace lost and damaged anatomical bone structures, renew their original function, and at the same time, to restore the original aesthetic visual aspect. This work is focused on a demonstration of the design methods, fabrication and surgical techniques of the custom-made replacement of a large defect of the frontal bone on the skull. The patient was a 30-year-old woman with a defect of the frontal bone in the size of 7 x 3 x 2 cm after a serious polytrauma.

[Custom-designed 3D tibial augmentation for knee replacement].

Reconstruction with the use of custom-made implants aims at optimal replacement of lost or damaged bone structures and restoration of their funkction. In this study the development and construction of a custom-made implant and the operative technique used for the treatment of an extensive tibial defect are described. The patient was a 65-year-old man treated for over 20 years for psoriatic arthritis and severe instability of the right knee, particularly in the frontal plane, with a worsening varus deformity.

Analyses of the temporomandibular disc.

This project is the beginning of a large research work with a goal to develop a new total replacement of temporomandibular (TM) joint. First aim of this work was to determine the relative displacement of the TM disc and the mandible during mouth opening. The movement of the TM disc was studied using a magnetic resonance imaging.

The examination of the temporomandibular joint on 1,5T magnetic resonance.

The most frequent intraarticular disorder of the temporomandibular joint (TMJ) represents the disorder of the functional relation between the articular disc and mandible condyle, i.e. dislocation of the articular disc.
