In our clinic, we have been using Straumann(r) CARES(r) CAD/CAM fabricated zirconium dioxide abutments since 2009 on a daily basis in esthetic cases with bone level implants, and have had no issues with abutment fractures so far.
The correct CAD/CAM design of a zirconium dioxide abutment and the quality and precision of the connecting part into the implant play a crucial role in long-term success.
Another study found that soft tissue around zirconium dioxide heals faster than when in contact with titanium13.A systematic review14evaluating the existing literature on zirconium dioxide abutments concludes based on evidence from animal and human histological studies that zirconium dioxide is as suitable a material for dental implant abutments as titanium.
Therefore, the choice of abutment is of major importance, especially in a sensitive region like the esthetic zone.For single-unit reconstructions, zirconium dioxide abutments are indicated, which can be either standard or customized depending on the prosthetic position of the implant.
For multi-unit reconstructions, zirconium dioxide abutments are recommended for cement-retained bridges, and gold titanium abutments for screw retained bridges.Abutment selection in posterior sites:Clinical indication of each implant abutment type depends primarily on the prosthetic position of the implant and whether single or multiple units need to be replaced.
