Faïd Souar II was discovered by G. Laplace (1954). His age was between 18 and 25 years old. 7000 years B.C. It was a Prehistoric osteoimplanted dental prosthesis. Indeed, tooth #15 had been replaced by a dental pseudo–element which was neither a human tooth, nor an animal tooth. It was neither made in ivory, nor in wood but in bone. It was perfectly still, without any trace of bonding (20 mm long, 8mm long in the bone). It was a small–sized bone such as the bone of a hand, a human foot or a foot of a small mammal in which this tooth was carved, then placed in the mouth. However, it was impossible to know the reasons why it was there. The texture of the bone tissue was the same as that in these mammals, only the morphology had changed. The radiographs that we carried out confirmed it.
