摘要：
method for surface preparation of dental or orthopedic implants. A method for surface preparation of devices made from titanium or titanium alloys, zirconium, zirconium dioxide, alumina or zirconia / alumina compounds, medical grade stainless steels and cobalt-based superalloys for medical use form the object of the invention； said devices being implantable in the human or animal body and attached extracorporeal parts made of the same materials, particularly for dental and orthopedic implantology. The implantable device is thus treated: it is provided to expose at least a portion of the surface of said device to a solution comprising hydrofluoric acid, phosphoric acid, at least one surfactant and water. exposure occurs over a period of time and under conditions sufficient to provide the implant surface with the desired surface roughness and self-inducing surface titanium dioxide formation while maintaining the structural integrity of the device and without changing the size centesimal measurement The surface thus treated is rinsed with demineralized water and ultrasound in order to avoid the metallosis phenomena. In extraosseous parts complementary to the devices to be implanted in the bone, nanometer particles of trace elements are applied, less than 20 nm, and in particular 99.9% pure silver, having the function of self-cleaning and which adheres to surfaces treated with the method described above without the aid of adhesives.método para a preparação de superfície de implantes dentários ou ortopédicos. um método para a preparação da superfície de dispositivos feitos de titânio ou de ligas de titânio, de zircônio, dióxido de zircônio, compostos de alumina ou zircônia / alumina, aços inoxidáveis de utilização médica e de superligas à base de cobalto para uso médico formam o objeto do invento； sendo os referidos dispositivos implantáveis no corpo humano ou em animais e partes extracorporais ligadas feitas com os mesmos materiais, particularmente para a implantologia
