Titanium copings veneered with Procera ceramics: a longitudinal clinical study.
In 1989, 47 titanium copings veneered with a low-fusing ceramic were fabricated for 24 patients. Forty-four crowns could be examined after a period varying between 26 and 30 months. It was found that the bulk ceramic of two crowns had fractured. California Dental Association ratings for "Surface and Color" had changed markedly from the "Excellent" to the "Acceptable" level, and for "Anatomic Form" there was a small shift from the "Excellent" to the "Acceptable" level. The factor of "Margin Integrity" was recorded as "satisfactory" for all crowns and a large majority were rated "Excellent."
