Implant is the core consumables, because the use of pure titanium or titanium alloy that will not cause human rejection requires a lot of scientific research and long-term clinical practice, and the production cost and technology content are high, so it is the main cost of surgery.
Implant systems are usually classified according to the material, shape and structure, surface structure and connection mode of implants. The clinical practice of oral implantology makes the contemporary oral implant materials and implant morphology tend to be single. Implants are mainly made of grade 4 commercial pure titanium, and threaded columnar and root implants have become widely accepted implant forms all over the world.
Studies have proved that moderately rough surface structure can increase the surface area and bone bonding of implants. Therefore, the implant systems currently used in clinic are generally rough surfaces with different roughness obtained through various surface treatments. The implant is connected with the prosthesis above it through a certain structure, which is mainly divided into external connection and internal connection.
