[Pathohistological study on the effect of various methods of osteosynthesis on the osteogenesis in experimental fracture of the lower jaw].

The lower jaw of 60 dogs was fractured and effects of wire and three variants of chemical osteosynthesis have been followed up concerning validity, course and rapidity of osteogenesis. A wire of 0.4 mm in the diameter was applied in wire osteosynthesis and autopolymerizing acryalte ("Simplex" Galenica) in chemical osteosynthesis with briding of the fracture line interfragmentarily or mixed with bone scrapings. The pathohistological examinations performed 7, 14, 21, 60 and 90 days after the intervention and osteosynthesis employment have shown that there is no difference in validity, course and rapidity of osteogenesis in fractures of the lower jaw under conditions of wire and pure chemical osteosynthesis. Since there is no histochemical obstacles and taking into account advantages of chemical over wire osteosynthesis it should be recommended in fractures of the lower jaw.
