Gloomy forecast for Nobel Direct after three years

Three years after patients were given Nobel Direct dental implants, the risk of the implant loosening has increased even more. A follow-up by researchers at the Sahlgrenska Academy shows that eight per cent of the implants are lost. “We have followed up 48 patients who were among the first to get the implant. For each passing year, we have been able to see how the problems related to these implants have grown more and more,” observes Pär-Olov Östman, a dentist who will be presented the study tomorrow at the defense of his dissertation.
After one year, about five per cent of the implants had been lost, and 20 per cent of the remaining implants showed bone loss of more than three millimeters. The new report indicates that after three years, eight per cent of the implants had been lost, and 25 per cent of the remaining implants showed bone loss of more than three millimeters. “We believe that the problems related to Nobel Direct result both from the design of the implant and an uneven surface against the soft tissue in combination with the method of treatment recommended by the company,” according to Professor Lars Sennerby.
