The 13th 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 "Twilight between Soft and Hard Tissue Grafts for Periodontal and Implant Reconstruction" and hands-on workshops.

Hard tissue augmentation without soft tissue coverage and soft tissue grafting without proper hard tissue support will not result in a predictable treatment outcomes. Hence, soft and hard tissue management around natural dentition and dental implants are key for successful overall treatment outcomes. Creating ideal periodontal and peri-implant soft and hard tissue conditions enables clinicians to achieve desired esthetic outcomes and maintain long-term treatment stability. This symposium invites internationally recognized experts in these fields to discuss resolutions to these 'twilight' challenges. Recent research evidence and newly developed clinical techniques and tips will be shared with all participants. The pros and cons of techniques used to treat complications of soft and hard tissue grafting will also be discussed.

On Thursday afternoon, pre-symposium lectures, a reception, and 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.

michigan football stadium


Michigan Stadium. The Big House. Home of Michigan Football. One of the country's most classic, widely recognized sporting facilities, Michigan Stadium has come to symbolize the pride, tradition and excellence of the University of Michigan. There is truly no place like it on a fall Saturday afternoon.

In the early 1920s, Fielding Yost formed a vision that would become Michigan Stadium. With winning teams and large fan turnouts, Yost realized the need for a larger football stadium. He asked for the Regents' approval, but considering the 1921 expansion of Ferry Field, they were hesitant to move forward with a new stadium. With Yost's dogged perseverance, they finally approved it on April 22, 1926.

The new structure was built on land that had been home to an underground spring. The water posed a problem to the construction, creating a surface that resembled quicksand. It was this moist ground that during construction, engulfed a crane which remains under the stadium today. The high water table also led to nearly three-quarters of the stadium being built below ground level.

Yost envisioned a stadium that would seat between 100,000 and 150,000 people. After much debate, the Regents, the University of Michigan and Fielding Yost reached an agreement by which the stadium would seat 72,000, with the ability to expand to more than 100,000. The construction would be financed not by the taxpayers of the State of Michigan, but by the sale of 3,000 $500 bonds.

Fashioned after the Yale Bowl, 440 tons of reinforcing steel and 31,000 square feet of wire mesh went into the building of the 44-section, 72-row, 72,000-seat stadium at a cost of $950,000. As the stadium neared completion, Yost requested an additional 10,000 temporary seats for the concourse. This request was passed, and Michigan Stadium opened at the corner of Main Street and Stadium Boulevard with a capacity of 84,401 -- the largest college owned stadium of any team in the nation.



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.
