If you've been credentialed by the American Academy of Implant Dentistry and its American Board of Oral Implantology/Implant Dentistry, you can now freely promote it. In October, a California federal court judge ruled that state laws prohibiting advertising such credentials are unconstitutional.
In his decision, the judge said, "The AAID and ABOI are bona fide credentialing organizations whose standards are rigorous, objectively clear, and verifiable."
Assuming anyone who's gone through the rigorous credentialing process didn't need the judicial system to tell them that.
Props to both groups and the docs who've trained with them. And, Fellows and Diplomates, let your patients, current and prospective, know.
