I truly doubt that there is fundamentally accurate data out there about the number of implants are used across the globe. I live and work in the United States and I am pretty certain that if you ask people from universities, industry, practice or whatever other group you'd prefer to include you will receive an answer that is variable.
Some countries have a better idea than others but uncertainty continues.
You can look at studies like those performed by Derks and others that have surveyed implant databases within certain countries but data cannot be extrapolated from what they have done to the entire rest of the world.
Yes very correct prof steve , that’s what is happening. I just tried for indian market alone , but the data collected varies, the one we did get from companies . we cannot considered the sale data. As all the implants bought are not placed and restored in the same year . So its better the companies start collecting the data of implants used from dentist . That will be a good way of retrieving the no. Of used implants .
Definitely I think companies should be the ones releasing the numbers (they may have already). And despite not all the sold implants are placed immediately, I believe a pretty accurate number can be estimated from their numbers.
The American Academy of Implant Dentistry (https://www.aaid-implant.org/dental-implants/what-are-dental-implants/) has some numbers on their page, but I am not sure they mention where those numbers come from. The ADA also has some numbers (http://www.ada.org/~/media/ADA/Publications/Files/ADA_PatientSmart_Implants.ashx) but again, no main source of information from where those numbers come from.
In Sweden, which is likely one of the countries in the world with the highest number of implant per capita the population is around 10 million. According to the Swedish Dental J on Nov 15, 2019, last year 65.000 dental implants were placed. That would be a factor of 1:158. Not sure how you can extrapolate to a global population but it may be a fun question the next time one plays a game of Trivial Pursuit.
As far as i know, "The National Institute for Health and Welfare in Finland (THL) has maintained the Finnish Dental Implant Register since April 1994" . it is the only country in the world with dental implant registry. example of such results from the registry

, it was stated that " The annual global dental implant market is estimated at around 12–18 million implants sold "." In Europe alone, the annual market has been esti‐mated at 5.5–6 million implants ".
