Patients who need implants will want to know more about the implants they are about to place. At present, there are more than 100 imported implant systems registered with the State Food and Drug Administration in China, and in the face of such a wide range of implant systems, it is difficult even for the implantologists themselves to figure out, let alone the patients. The international mainstream implant system companies are Swiss Straumann AG, Sweden Nobel Biocare AB, Germany Dentsply, BEGO, Camlog, the United States Biomet 3i, Zimmer, France Anthogyr …… can not be described in detail. Each company also has different product lines under its umbrella, and usually one company’s products can meet all the growing needs. The Swiss Straumann system, for example, is divided into soft tissue and bone tissue according to the platform level, SLA and hydrophilic SLactive according to the surface treatment, and titanium implants, titanium-zirconium implants (mainly used for fine implants to increase strength) and ceramic implants (in clinical application tests) according to the material. Each type of implant has its own indications, depending on the amount of bone, bone quality, soft tissue, location, etc. of the patient’s missing teeth.
