Jaw Defects

Cancer of the lower jaw is one of the most common causes of the development of total defects. There are many indices and indicators to assess the quality of life of patients with this pathology, but they do not fully describe the features of their postoperative rehabilitation. The question of developing an evaluation criterion for the introduction of a special device in patients with subtotal defects of the lower jaw remains open.Material and methods. In the period from 2010 to 2021, 100 patients with subtotal defects of the lower jaw, aged 30 to 65 years old, who are being treated in the Department of Maxillofacial Surgery at the Department of Maxillofacial Surgery of the GBUZ SKKKB, were interviewed. All patients were divided into 2 groups of 50 people each. In the main rehabilitation was carried out using a special device to optimize the biomechanics of the lower jaw, in the control group, rehabilitation was carried out without one. The article presents the results of assessing the quality of life, which were carried out using a special questionnaire.Conclusions. This questionnaire makes it possible to assess the standard of living of patients using a special device at the stages of rehabilitation.

The presented work is focused on stress - strain analysis of a reconstruction plate. For this problem the computational modelling was chosen with using finite element method. Mandible was created based on the methods of Reverse Engineering and CT images. Using these methods a STL model of mandible with cortical and cancellous bone tissue was created. A volume model of lower jaw with applied reconstruction plate was created in CAD software. A Symphysis fracture of lower jaw was modeled in calculation program ANSYS. The cancellous bone tissue is modeled with different mechanical properties, which corresponds to the varying quality of this tissue. In this work an influence of varying quality of cancellous bone tissue to von Mises stress is observed.

. This work is focused on stress - strain analysis of a mandible fracture behavior in the case of straight and oblique fracture. For this problem the computational modelling was chosen with using finite element method. Mandible was created based on the 3D scanning and CT images. Using these procedures a STL model of mandible with cortical and cancellous bone tissue was created. A volume model of lower jaw with applied reconstruction plate was created in CAD software. Fracture in the chin region was modelled directly in the program ANSYS. The cancellous bone tissue is modeled with different mechanical properties, which corresponds to the varying quality of this tissue. An assessment of differences in the behavior of straight and oblique fracture is presented in this work.
