Experimental fractures of the mandibular body of sheep and dogs. A new technique.
In order to create artificial fractures in animals resembling those which occur naturally, a new technique for fracture production was developed. Using a specially designed clamp, artificial fractures were produced in the mandibular body of seven sheep and 12 dogs. Radiographical analysis of the effects of the clamp on the mandibular body showed simple, single vertical fractures in the buccal cortex, inferior border and the alveolar process comparable to those which occur naturally. Using the technique described it was possible, in all cases, to carry out treatment with the use of 4-hole poly(L-lactide) plates and screws.
