MY STORY

In 2005, I had been practicing as a periodontist for about 10 years. At that point I was really curious to know how many dental implants I had placed and more importantly what was my complication rate. I decided to establish a retrospective chart review. Having been an early adopter of digital radiography, I was able to go back to 1998 to 2005 in my digital files.

I looked back at each case and created columns on the type of information I wanted to evaluate overtime to develop a database of my dental implant cases. I then used the same format of this electronic record to incorporate all cases from 2005 onward to present. After 20 years the real time database evaluates over 12,000 implants with 25 input variables.

 

This database was instrumental in publishing unique clinical studies relating to real world outcomes because most published research in dental implant journals evaluates only a small number of cases in a very controlled environment, such as university settings, for a few years.

There was really a lack of large scale, long term follow up of cases representing the real world environment of every day private practice where the control of risk factors is not possible.

With the help of specialized statisticians we were able to establish the world largest private practice database on implant dentistry. By incorporating risk factors and evaluating variables we can now assess when a technique change or product use affects dental implant outcomes over a long term follow up.

What started out as a few simple questions, “how many implants have I done and how are they doing?” now provides a very rewarding research career and the opportunity to collaborate with esteemed researchers all over the world.

We have had research awards at conferences, our papers are highly cited in the literature including a recent paper which was the top read article from the Journal of Periodontology over the year 2019.

I am happy to contribute this knowledge base to the dental profession. I use it as part of my lectures and more importantly every day in private practice when I am helping patients decide on a treatment option that best suits their needs.
