March 21, 2016 | Leave a comment Some states allow the listing but it does not necessarily mean that an individual is board certified. Any graduate of an accredited dental school is permitted to practice prosthodontics. Some individuals choose to receive additional post-graduate training and complete a three-year program in prosthodontic training. Many of these individuals choose to become board certified but some do not. Board certification establishes that the individual has successfully completed a four-part examination and is subjected to re-certification every eight years to ensure that he/she is current in practices that affect the specialty.
