Proven system performance – Nobel Biocare

In a five-year follow up of a controlled clinical trial comparing the outcomes of NobelProcera titanium versus zirconia abutments, the authors reported no screw loosening, abutment or crown failures for either tested group.1

Over the long-term, excellent clinical outcomes of NobelProcera zirconia abutments have been reported. A 10-year follow-up study found patients and clinicians to be extremely satisfied with the esthetics of the restoration, low rates of biological and technical complications, small changes in peri-implant bone levels, and excellent implant survival rates.2

Findings from in-vitro experiments on Nobel Biocare CAD/CAM abutments point to high system stability and resistance to screw loosening,3 and rotational freedom below the threshold associated with screw loosening.4-7

Low risk of screw loosening 

In a recent study NobelProcera Abutments were concluded to have a lower risk of screw loosening compared to other abutments tested, thanks to a minimal settling effect on loading and low micro-movement at the implant-abutment interface.8 NobelProcera abutments remained close to their position at insertion providing high joint stability.

Predictable, strong performance

Recent research by leading materials expert Prof. J. Robert Kelly looked at the fatigue strength of zirconia abutments. The four abutments looked very similar in clinical examination but differed in performance, indicating the impact of design and production method.9

NobelProcera products demonstrated outstanding performance in this research, leading Prof. Kelly to conclude that "Nobel Biocare is a high-quality manufacturer. The company manufactures components that are designed, tested and then verified."

Low mechanical complications with angulated screw channel solutions

Greer et al. investigated mechanical complications associated with NobelProcera angulated screw channel restorations, following placement of the final prosthetics. They found that 96% of the restorations placed experienced no complications during up to a two-year follow-up period.10

NobelProcera products with angulated screw channel proved to be a reliable, flexible and retrievable alternative to traditional cement- or screw-retained restorations. Moreover, 38% of the restorations were fitted by post-graduate trainees. This highlights the ease of use of the ASC solutions.
