[The biomechanical basis of mandibular osteosynthesis in the area of the alveolar process]

Analysis of mandibular efforts in exercise shows that the strain depends mainly on the force moment and is linearly distributed along the height of the transverse section. The maximal stretching strain is recorded in the superior portion, the maximal compression strain at the edge of the mandible. This results in the development of diastasis in the alveolar section. With regard to the twisting moment and the force moment of the fixator, the optimal site for the fixator is the upper edge of the mandible; the higher it is placed in relation to the point of the fractures rotation, the less force is needed for fixing the fractures in the proper position, and vice versa, the lower the fixator is placed, the stronger it should be.
