There are a lot of dental implant manufacturers! The dental implant field is very competitive, and a lot of companies want to jump on the bandwagon. Quite a few of them have copied or "borrowed" ideas from others.
But there is a core of less than FIVE manufacturers that have a proven high-quality product with research and a track record behind them.
One of the first with a documented research record was AstraTech. This is part of the swedish company AstraZeneca.
When I went to an AstraTech course in Gothenburg, Sweden, a few years ago, they explained that record.
Because Astra was originally a pharmaceutical company, they had to document ALL their drug and pharmaceutical research precisely. Otherwise the products would not receive approval to sell to the public.
So, when the AstraTech division started research into dental implants, they documented everything the same way, just as if it were pharmaceuticals.
No other dental implant manufacturer did this at first. And so AstraTech has the longest research record of any company, because it's just the way things were done at Astra! And still today, AstraTech is widely regarded as being a very high quality implant.
Ankylos is the only other implant system (apart from Astra) that a particular piece of research showed did not suffer from potential "microgap" problems. This microgap is a microscopic space that may open up between the implant itself and the crown on top, during chewing.
It's important because bacteria can get in there and set up a chronic low-grade infection. This can cause mild redness and swelling of the gum around the implant. It's more annoying than anything else. But it can cause a bad odor. And it MAY cause enough inflammation over the course of a few years to weaken the implant attachment to bone. Then the implant works loose.
Ankylos is an excellent, well-researched system from a reputable company.
Straumann / ITI is a swiss system. ITI stands for International Team for Implantology. This is a group of top dentists who got together to agree on set standards for dental implants. This group is still active, and has a very close association with Straumann. This implant system is also an excellent one.
Nobel Biocare + Branemark. Of course, Professor Branemark is the "father" of modern dental implants. (read about dental implant history. ) Nobel Biocare has since acquired the Branemark company, and still includes the Branemark design in its range. However, there have been significant advances, and Nobel Biocares' own implants are now a better choice.
The dental implant manufacturers listed here are, in my personal opinion, among the best available. There are very many others, but few will have the scientific evidence of how well their implants work over 10 or 15 years. If this is important to you, ask your dentist what dental implant manufacturer is being used, and how many years of research they have.
