[Tooth transplantation].

In the light of the thesis of J. Thibault, the authors suggest, in association with transplantation of wisdom tooth buds into the alveolus of the first molar, a technique consisting of placing the graft in its pre-eruptive position, removing in a block the bud, the gubernaculum and the sub-jacent gingival mucosa. Under these conditions, eruption occurs at the same time as development of the roots, which represents the most physiological solution. At the same time as formation of the root, the authors noted a paradoxal rhizalysis, hypercementosis resulting in ankylosis and conservation of vitality. In addition, almost all the teeth transplanted proved to be highly vulnerable to caries.
