Objective: Compare the cervical implant-abutment fit of a single porcelain-fused-to-metal prosthesis obtained by Procera system, namely, a titanium milling technique. Methods: This investigation was conducted in two different stages of the manufacturing process, of three element implant-supported prostheses, through scanning electron microscopy analysis. The first stage assessed was after the customized abutment milling. The second stage was after porcelain sintering. Ten abutments were milled for each element, resulting in 30 titanium elements and 10 fixed partial substructures. Eighteen reference marks were distributed in the buccal and lingual surfaces of the three implants. One-way ANOVA statistical analysis was used for group comparison at 95% confidence level. Results: The results suggested that stage 2 presented significantly (P = 0.05) higher values than stage 1. Conclusion: The customized laser soldered milled titanium abutments are a clinically acceptable treatment procedure for porcelain-fused-to-metal fixed partial prostheses.
