Confidence and reliability: Excellent long-term
prosthetic survival, with minimal marginal boneloss independent of bridge type, implant type andconnection, or loading protocol.
Healthy soft tissue response: Low rates of peri-implantmucositis and peri-implantitis confirm excellent biocompatibility of zirconia.
Minimal marginal bone loss at restorations connectedat both abutment and implant level.
CAD/CAM zirconia frameworks offer precision, passive
fit and high material quality: Few technical and biologic
complications, credited to industrial design.
This study confirms the success of original prosthetics on
Nobel Biocare implants.

− Minimal marginal bone loss of 0.18 mm fromdefinitive prosthesis delivery to last follow-up
independent of bridge type, implant type andconnection, or loading protocol.

follow-up− Minimal marginal bone loss of 0.17 ±0.62 mm for
implant-level prostheses and 0.20 ±0.43 mm forabutment-level prostheses.
− Healthy soft tissue with low rates of peri-implantmucositis (2.7%) and peri-implantitis (3.8%) overlong-term.
− High patient satisfaction and excellent
long-term esthetics.
