Abstract:

OBJECTIVE

The aim of the study was to analyze a three-dimensional finite element model of a post-resection defect of the lower jaw, design and producing of an individual reconstructive plate, compare the stress-strain of this plate using standard reconstructive «CONMET» plate for stabilizing the lower jaw segments through a simulation of the chewing load.

MATERIAL AND METHODS

The study was carried out on two identical finite elementary models with bone defects in the body of the lower jaw by fixing with a standard reconstructive «CONMET» plate and designed reconstructive plate. In order to simulate the biomechanical loads on the plates when chewing, an impact of force during the occlusal contact of the incisor was applied. The magnitude of the vertical load was equal to 150 N. The condylar processes were fixed in all three directions to prevent reaction forces in the temporomandibular joint.

RESULTS

Comparative analysis of two fixation methods showed higher value of equivalent Von Mises stress in individual reconstructive plate than in standard plate.

CONCLUSION

Individual reconstructive plate has better strength characteristics compared to the standard reconstructive «CONMET» plate.
