[Mandibular osteosynthesis according to the Michelet technic. I. Biomechanical bases].

Experiments performed in collaboration with a group of engineers lead to following affirmations: - mandible's external cortex is strong enough to endure strains resulting from screws, - osteosynthesis plate must be screwed in high position, - the material elaborated according to biomechanical data appears constantly reliable despite more marked miniaturization and improved malleability.
