The Brazilian standard ABNT NBR 16044 defines the general requirements for dental implants. It specifies several elements and, among them, the contact between materials of different chemical composition. The standard mentions another standard (ABNT ISO 21534), which defines that the combination of ASTM F138 stainless steel, to be used as the material for the manufacturing of the abutment, and of Ti6Al4V, used for the manufacturing of the implant, is considered adequate for the application, allowing it to be used without any problems. The setting promoted by the different materials promotes a contact area that is even more efficient in relation to connection airtightness and stability.
