Abstract: The present invention concerns a method of manufacturing a dental implant comprising: preparing an implant composed of a root portion and a crown portion and constituted by an inert biocompatible material in a shape which is adapted to an extracted tooth; immersing the root portion of said implant into a culture of undifferentiated mesenchymal cells in a culture medium the composition of which allows differentiation into cementoblasts and fibroblasts, over a period which is sufficient for said differentiation and for adhesion of cementoblasts to the root portion and the formation of a first layer of cementum and an alveolodental ligament primordium attached to said cementum; recovering the implant carrying differentiated tissues affixed to its root portion.

Abstract: A method for transplanting human or animal teeth while eliminating the risk of ankylosis and root resorption. This method involves stimulating the periodontal ligament prior to transplanting the teeth by causing surgical trauma to the periodontal ligament by mobilization of the teeth (extraction and immediate replantation) and retaining them in a mobilized position to cause mechanical stimulation.
