Landmark science

by: Frederic Love

Nobel Biocare has the longest, most extensive follow-up data set. Without two pioneering studies from 1981 and 1990, implant dentistry might still be in its infancy today.

Landmark Science

Many studies have been carried out on the procedures and consequences of osseointegration since Per-Ingvar Brånemark treated his first implant patient, Gösta Larsson, 47 years ago in 1965. Perhaps none has been more widely read than “A 15- year study of osseointegrated implants in the treatment of the edentulous jaw” by Ragnar Adell et al, which was published in the International Journal of Oral Surgery in 1981.

In this groundbreaking work, and the follow-up study published in 1990, Adell and his colleagues meticulously documented the high success rates generated by implant treatment ad modum Brånemark and produced an impressive yardstick against which all subsequent studies would be measured.

Dr. Adell, formerly head of the Department of Oral and Maxillofacial Surgery at the Örebro University Hospital in Sweden, recently commented, “When we started our work in the 1960s, the possibility of the body permanently retaining a titanium fixture was not widely accepted. By the time our second report on this study was published in 1990, the process of osseointegration had become accepted science.”

Thanks in large part to the pioneering work of Adell and his colleagues, the viability of the routine placement of endosseous implants became wellknown among readers of dental literature in the 1980s and 90s—and the rest, as they say, is history.
