Title (EN) A DENTAL OR ORTHOPAEDIC IMPLANT
(FR) IMPLANT DENTAIRE OU ORTHOPEDIQUE
Abstract:
(EN) A dental or orthopaedic implant comprises a metal or metal alloy whose surface has been converted at least over part of its area to an oxide film X, the oxide film comprising a calcium phosphate-containing material as a composite component over at least part of its area Y. The metal or metal alloy preferably comprises a Group IIIA or IVA transition metal or alloy containing the same, and more preferably comprises titanium. The metal or metal alloy surface of the implant is preferably oxidised and/or the composite is preferably formed by Plasma Electrolytic Oxidation. The calcium phosphate- containing material preferably comprises an apatite, for example hydroxylapatite, or tricalcium phosphate. In a preferred PEO process, high frequency current pulses of a particular form, and within a particular frequency range, are used, combined with the generation of acoustic vibrations in 20 a sonic frequency range in the electrolyte, the frequency ranges of the current pulses and the acoustic vibrations overlapping.
(FR) Un implant dentaire ou orthopédique comprend un métal ou un alliage métallique dont la surface à été transformée au moins sur une partie de sa surface X en un film d'oxyde, ce film d'oxyde comprenant un matériau contenant un phosphate de calcium sous la forme d'un composant composite sur au moins une partie de sa surface Y. Ce métal ou cet alliage métallique comprend, de préférence, un métal de transition du groupe IIIA ou du groupe IVA ou un alliage contenant ce métal et, dans un mode de réalisation plus préféré de l'invention, il comprend du titane. Cette surface de métal ou d'alliage métallique de cet implant est de préférence oxydé et/ou le composite est de préférence formé par oxydation électrolytique par plasma. Le matériau contenant du phosphate de calcium comprend, de préférence une apatite, par exemple une hydroxylapatite ou un phosphate de tricalcium. Dans un processus d'oxydation électrolytique par plasma préféré, on utilise des impulsions de courant de hautes fréquences d'une forme particulière, dans une gamme de fréquences particulière, combinées avec la génération de vibrations acoustiques dans une gamme sonore particulière dans l'électrolyte, les gammes de fréquences des impulsions de courant et des vibrations acoustiques se chevauchant.
