Purpose: The aim of this retrospective study was to evaluate the 5-year clinical outcome
for ceramic veneered cobalt-chromium (Co-Cr) fixed dental prostheses (FDPs) fitted in a
private clinical setting. Materials and Methods: All patients treated consecutively with
Co-Cr FDPs from January 2000 to November 2005 were included, and complications
were registered. Patient records were examined for details on the restorations and
abutment teeth. A total of 149 patients with 201 FDPs, 1,135 units, and 743 abutment
teeth were recorded. Results: Of the 149 patients, 122 (82%) were followed for 5 years.
Complications occurred in 34 patients (23%) and 38 FDPs (19%). The most frequent
were caries (6.7% of patients, 5% of FDPs, 2.2% of abutments) and cement failure (6.7%
of patients, 5% of FDPs, 3.1% of abutments). Cohesive ceramic fractures occurred in only
7 FDPs (3.5% of FDPs, 0.7% of units). No adhesive ceramic fractures were recorded. The
5-year cumulative rates for success and survival were 83.8% and 92.8%, respectively.
Conclusions: Co-Cr FDPs appear to be a promising prosthodontic treatment modality,
presenting low incidence of complications and a high survival rate during the first 5 years
of function. However, long-term randomized controlled studies are necessary to confirm
these findings. Int J Prosthodont 2013;26:343–349. doi: 10.11607/ijp.3024
