There has now been a radiographic follow-up after five years of loading which showed that all implants functioned well. The median marginal bone loss for control implants was found to be 0.70mm, which is less than commonly reported in the literature. The bisphosphonate-coated implants showed even less resorption, 0.20mm. These new data suggest that bisphosphonate-coated implants enable prolonged preservation of the marginal bone.
