Digital Innovations for Comprehensive Treatment Planning, Surgery, and Artificial Intelligence


The 14th Biennial Ramfjord Symposium is a tribute to Dr. Sigurd Ramfjord and his contributions to the field of periodontics. The program brings together internationally renowned speakers who have expertise in long-term periodontal care and emerging scientifically based treatments. It provides a comprehensive insight into critical issues involved in delivering ideal treatment for clinical practice.

This year, symposium Scientific Chairs, Dr. Purnima Kumar and Dr. Hom-Lay Wang, will preside over lectures and a poster session on the topic of “Digital Innovations for Comprehensive Treatment Planning, Surgery, and Artificial Intelligence,” and hands-on workshops.

On Thursday afternoon, pre-symposium lectures, a reception, and a poster session will be held on the 4th Floor of the Rackham Graduate School.


Sigurd P. Ramfjord, a pioneer in treatment of periodontal disease, was born in 1909 in Kolvereid, Norway. He received his dental education at the Oslo University School of Dentistry in 1934 and subsequently practiced dentistry in Norway for 12 years before coming to the University of Michigan in 1946 for graduate work.

He earned a master's degree in periodontics in 1948 and a Ph.D. in oral pathology in 1951. By 1963, he not only had joined U-M faculty but also served as chair of the Department of Periodontics and Oral Medicine – a position he continued to hold until 1981.

He is credited with performing the first long-range study of various techniques of periodontics, the branch of dentistry concerned with gums and other structures that support teeth. He followed a group of patients for more than 10 years, bringing scientific comparison data to the field.

The dental education program Ramfjord developed over the years known as "the Michigan Concept" has been emulated around the world. He organized the first World Workshop on Periodontics in 1966, where scientific goals for the field of periodontology were established.

A prolific writer, Ramfjord authored two textbooks and more than 90 publications. In recognition of his worldwide influence, he received a number of honors and awards over the course of his career, including the Gold Medal Award in 1973 from the American Academy of Periodontology.

In recognition of his more than 20 years of consultant work with the World Health Organization, he was awarded an honorary doctor of dental medicine degree by the University of Geneva, Switzerland, in 1978, and an honorary doctor of odontology degree by the University of Gotenborg, Sweden, in 1979. The University of Michigan honored him with its Distinguished Faculty Achievement Award in 1979

Apart from his many other achievements, Ramfjord was active in many dental organizations. He served as president of the American Academy of Periodontology and also served as director and chairman of the American Board of Periodontology. He was a fellow of the American Academy of Oral Pathology, the American Association for the Advancement of Science, the American College of Dentists and the International College of Dentists.

Submit an Abstract


Of special interest is the complimentary social event at the University of Junge Family Champions Center on Friday night.

Participants of the Ramfjord Symposium are invited to attend. Light hors d'oeuvres will be served.


When John Junge and his family learned in 2002 that the Michigan Athletic Department sorely needed an events center for recruiting, banquets, press conferences, and meetings, the family donated more than $2 million toward the construction of an 11,400-square-foot facility. This facility provides a central recruiting location for University of Michigan athletics, and is also a venue for team banquets, press conferences, and other events.



Rackham Graduate School is located at 915 E. Washington, Ann Arbor MI 48109.



The trip between the Detroit Metro Airport and Ann Arbor takes about 20-30 minutes.

Taxi costs around US$ 50. They usually take 3 people (it is not necessary to make reservations for the taxi).

Other options include Lyft, Uber, and a shuttle, the most economical option.

Another alternative (a bit more expensive) is to take the Metrocar Services. The driver will wait for you at the baggage claim, pick up your bags, and bring you to Ann Arbor (they generally take up to 3 people). For both shuttle and Metrocar, it is important to make the reservation online before your arrival


June is relatively a hot month for Ann Arbor. Temperatures can range from 62°F to 83°F. Precipitation can range from light rain to thunderstorms.
