Before you invest money in your new teeth you want to make sure to find a good dentist that restores implants on a regular basis. You can ask family and friends but to get inside information, it is best to call a few of your local or large national dental laboratories. Just look them up in the yellow pages or on the web. Since laboratories work with many doctors they have a very good idea which dentist in your area is a good practitioner and experienced with implants.
Once you have some recommendations, call the office and ask the receptionist if the doctor is a member of the ICOI (International Congress Of Implantology), AO (Academy of Osseointegration), AAID (American Academy of Implant Dentistry) or AGD (Academy of General Dentistry).
You also want to ask how many implants the doctor restores and or places in a given calendar year. Twenty implants and up is a nice indication of a practiced doctor.
To go one step further, there is a special class of restorative dentist called Prosthodontist. These doctors had to attend a couple more years of school after they became dentists and are specialized in restoring teeth with crowns, bridges and dentures.
