Abstract: The present invention relates to a temporary dental implant intended to prepare the alveola of an extracted tooth so that a selected dental implant can be inserted later. It also involves the use of this temporary dental implant from a functional and/or aesthetic point of view. It has, in addition, as its object kits, methods and tools, notably resin models, that can be used for the application or preparation of the above implants.

Abstract: The invention relates to a reactor for cell and tissue culture particularly suited to the culture of cells or tissues in the form of thin layers, and comprises the means for ensuring a physiological stimulation and supply of nutrients in culture medium adapted to the reduced thickness of the culture. The reactor can be used for the preparation of an implant and also includes the means of ensuring a mechanical stimulation of tissues or cells and supplying nutrients in culture medium suitable for structural tissues. The reactor also comprises, in an advantageous way, the means or a form that allows easy introduction of the tissue or the solid part of an implant into the culture chamber and, for example, a wall or an elastically deformable element. In addition, the reactor can include means of temperature regulation. The reactor can be used for the culture of different types of cells and the preparation of implants in a variety of forms, compositions and applications.

Abstract: The invention concerns a device and methods for providing implants, cells or tissues, for example for grafts or in vitro research cultures, of tissue engineering or cellular therapy. The invention is particularly adapted to produce, in sufficient amount, specific cell populations with high proliferation and/or differentiation potential, adapted for use in tissue engineering, in repair surgery or therapy, particularly for humans. The invention also concerns a method for preparing such a device and its uses, in particular for treating tissue loss, and kits, tranplants, tissues or biological preparations.

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.
