Comparison of marginal and internal fit of 10-unit fixed dental prostheses fabricated from cobalt chromium alloys or zirconia ceramics using digital workflows

A digital workflow yielded precise, clinically acceptable fit for 10-unit restorations fabricated from both cobalt chromium and zirconia. Zirconia demonstrated significantly higher marginal trueness, whereas the internal gap trueness did not differ significantly between the 2 materials. Optimizing cement spacer settings and evaluating deviations from the planned spacer are crucial for an accurate assessment of fit.
