Our Denture Specialist-Dr. Lillian Obucina
Dr. Lillian Obucina is an Assistant Professor at Midwestern University College of Dental Medicine, Downers Grove, Illinois, where she instructs dental students on everything they need to know about dentures! She teaches partial dentures, complete dentures, and implant-retained dentures, which are also called overdentures to second, third, and fourth year students.

Dr. Obucina is a 1988 graduate of Northwestern University Dental School, and she completed post-graduate dental training at Northwestern by obtaining a Certificate in Prosthodontics in 1990. Prosthodontics is the specialty area of dentistry that includes fabrication of crowns, bridges on natural teeth, implants, and dentures. During her two year prosthodontic program, Dr. Obucina focused exclusively on complex full mouth reconstructions. These days she limits her practice to denture-related treatments.

In 2002, Dr. Obucina graduated from the John Marshall Law School in Chicago. While in law school she concentrated her coursework on legal areas that would be useful to practicing dentists-business contracts, employment, licensure, patient confidentiality, record keeping, and malpractice. For many years she represented dentists in their legal matters: these days she teaches fourth year students on those same sbjects.

She has also lectured to dental groups locally and nationally, independently and on behalf of the American Dental Association, on topics of ethics, oral health literacy, and dental practice management. Recently, she became a committee officer on a group dedicated to ethics, professionalism, and legal concerns in dentistry with the American Dental Education Association.

In her spare time, Dr. Obucina enjoys travel, photography, and walking.
