Ceramic vs composite veneering of full arch implant-supported zirconium frameworks: assessing patient preference and satisfaction. A crossover double-blind randomised controlled trial.

CONCLUSIONS: No difference between the two treatments was detected for preference, changes of OHIP-21, complications, reduction of FMPS, VAS changes regarding patient satisfaction, chewing and phonetics. Nevertheless, a slight difference was detected in the VAS regarding aesthetic acceptance favouring the ceramic material.
FUNDING: The study was supported by Nobel Biocare (grant 2012-1077). Thanks to this contribution, the patients who consented to participate in this RCT were not charged for the material provided by Nobel Biocare. In addition, the patients benefited from a further back-up prosthesis that was provided to them completely free of charge. Conflict of interest statement: This is an author-driven study. The supporting company had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. The authors prepared the protocol of this study and the supporting company was permitted to review the manuscript and suggest changes, however, the authors exclusively retained the final decision on content.
