Artificially designed replacements are made from special materials precisely because artificial materials are implanted into living tissues. Careful consideration must be given to the materials used to ensure that tissues can tolerate this.
In this context, the implant, which serves as the foundation for crowns (artificial teeth), bridges, and dentures, must be stable and safe.
Most implants today are made of titanium. Titanium alloys are also suitable for interaction with surrounding tissues and the immune system.
