More than 10 years of clinical experience are involved. Probably it is the best implant supported screw retained bridge worldwide. The clinical results up to five years show that a titanium dental implant in combination with the SIEWERT BRIDGE is a better implant on a long term view. We observe a substantially reduced bone loss at the implant neck over the years, the incidence of periimplantitis is around 1% and the patients are more satisfied. This is due to the lack of metal, the shock absorption of the oclusal forces although the occlusion is a stable ceramic layer and minor inexactness of the fit of the bridge upon the multi-layer abutments is compensated what means that a Passiv fit is guaranteed.
