Biomechanical Stability of Juvidur and Bone Models on Osteosyntesic Materials.

INTRODUCTION

Artificial models can be useful at approximate and qualitative research, which should give the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite in the three-dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elastic characteristics, which are embedded in a complex organic structure.

THE AIM OF THE STUDY

Examine the budget voltage and deformation of: on the compressive and bending forces on juvidur and veal bone models and compared the results of these two methods (juvidur, veal bone).

MATERIAL AND METHODS

For the experimental study were used geometrically identical, anatomically shaped models of Juvidur and veal bones diameter of 30 mm and a length of 100 mm. Static tests were performed with SHIMADZU AGS-X testing machine, where the force of pressure (compression) increased from 0 N to 500 N, and then conducted relief. Bending forces grew from 0 N to 250 N, after which came into sharp relief.

RESULTS

On models of juvidur and veal bones studies have confirmed that uniform stability at the site of the fracture MIF with a coefficient ranking K=0,1971, K=0,2704, K=0,2727 i K=0,5821.

CONCLUSION

On models of juvidur and veal bones working with Shimadzu AGS-X testing machine is best demonstrated MIF with a coefficient of 0.1971.
