Photoelastic stress analysis on mandibular osteosynthesis.
An experimental study concerning mechanical behaviour and stability through mandibular osteosynthesis has been carried out. 3 different kinds of mandibular osteosynthesis: figure-of-8 wiring; ASIF--Swiss Association for the Study of Internal Fixation - compression plate; monocortical juxta-alveolar miniature screwed plate (Champy plate), were analysed in photoelastic model experiments. The strain distribution differs remarkably according to these 3 methods as well as stability against loading forces.
