Restorative Expanded Functions: An 80-hour Training Program

Bring a new dimension and greater clinical responsibility to your career with this practical, three-phase training and credentialing program. The Minnesota Dental Practice Act and other states' recently-passed statutes allow licensed dental assistants and hygienists to perform specific restorative procedures with personal supervision. You will benefit from one-on-one interaction with experienced instructors who will share a myriad of clinical tips based on years of practice and teaching experience. After completing our Minnesota board-approved course and receiving your Restorative Functions (RF) credential, your daily work opportunities will expand dramatically.
