This is a complicated subject that even most Dentists don’t understand. In summary, because there is no “best” implant for all situations, it is important to use an implant that has a scientific documented high success rate (not just an advertising claim), be from a reputable company that will probably still be here many years from now, for spare parts if needed, and the use of a particular brand design optimized for each particular patient. This is better than trying to use one kind of implant for everyone. Some systems we use are from: Nobel Biocare, Astra, Zimmer, HiOssen, Neoss, Alpha Bio, Dentis, Sweden & Martina, Straumann, Neodent, and Ankalos.
Also, we use manufacturers original restorative parts; no 3rd party parts are used. Unfortunately, the implant manufacturers world has become very complicated. Because many of the manufacturer’s patents have expired, many independent companies are cloning each other’s designs, however, it is unlikely that they are exact copies, as proprietary metallurgic treatments are still secret. Complicating matters further, Laboratories can now copy parts. This may result in poor tolerances and poor quality control, as now even small labs can do as they please. This may result in increased microleakage between parts resulting in bone loss around the implant over time.
To stress the complexity of this subject, for example:
Most implant designs use grade 2, 4, 5, or 23 titanium. Other designs cryo treat the titanium or use other materials, such as tantalum. Implant macro design topology include thread pitch angle, thread depth, thread number, and thread cross sectional designs. Micro design topologies are the microscopic surface roughness of various forms created by acid etching, surface blasting, and chemical treatments. Active chemical treatments involve using calcium, phosphorous, fluoride, and other compounds to create a bioactive surface. The design of the implant-abutment interface, usually categorized as an external, or internal connection, may be proprietary depending upon the implant system. Platform switching designs are the mismatch of a smaller diameter abutment mated to a larger diameter implant body interface and may have beneficial biological effects.
