[Clinical and experimental animal studies made to evaluate silastic and feeeze dried dura used in the treatment of orbital floor fractures (author's transl)].

A comparison has been made of the results obtained using Silastic and freeze-dried Dura in experiments on dogs treated for orbital floor fractures. Dura was found to be a better implant than Silastic because the former material will be completely resorbed and replaced by cicatricial connective tissue. Silastic tends to remain in its original site or position and may lead to secondary injuries because of its mobility. Accordingly, the latter material is indicated for use in the case of extensive fractures only.
