摘要: Membrane, used in particular for regenerating periodontal ligament, preventing the formation of adhesions or the regeneration and reconstruction of tissue, including at least one layer of fabric (N1) made of fibres (F) produced from at least one polymer. The fibres (F) are free of sizing, the layer of fabric (N1) has a non-woven arrangement of fibres disposed in a random or aligned manner, and the fibres (F) are coated with PolyNaSS (polystyrene sodium sulfonate).

摘要: A method of grafting a bioactive polymer on implants, the method comprising the following steps: a) mounting implants on a support structure; b) dipping the implants in a bath of acid; c) rinsing the implants; b) dipping the implants in an anodizing bath so as to anodize them; e) rinsing the implants; f) putting the implants into a polymerization chamber; g) mounting the implants on an elevator present in the chamber; h) actuating the elevator so as to dip the implants into a polymerization bath; i) subjecting the polymerization bath to a polymerization catalyst; j) raising the elevator from the polymerization bath; k) removing the implants from the elevator; l) extracting the implants from the chamber; m) washing the implants so as to remove any excess non-grafted bioactive polymer therefrom; and n) drying the grafted implants.
