Local Release of Bisphosphonates Improves Implant Stability

AddBIO AB, a subsidiary of Accelerator Nordic AB, has developed Zolidd®, a proprietary bioactive nanolayer for orthopedic and dental implants that releases bisphosphonate, a bone strengthening drug. A randomized clinical trial, conducted at Linköping University Hospital, Sweden, shows that dental implants with a bisphosphonate nanolayer have improved stability.

Millions of people worldwide have dental implants, i.e. screws inserted to support artificial teeth. The first time after surgery, the implant is often not stable enough to enable chewing. It may take several months for the bone around the implant to heal and become strong enough for the patient to regain normal chewing function.

“The study shows that local bisphosphonate improves implant stability, meaning that the time until normal chewing function could be shortened, thus reducing the suffering for the patient”, says Professor Per Aspenberg, Linköping University Hospital, co-founder of AddBIO.
