Clinical Follow-up of Porcelain Veneering on Titanium Crowns Produced by Different Techniques

March 3, 2026 updated by: Elif Ezgi, Ege University

Clinical Follow-Up And Evaluation Of Porcelain Veneering Titanium Crowns Produced By Different Techniques

This clinical study aimed to evaluate the short-term clinical performance of porcelain-veneered titanium crowns fabricated using two different techniques: conventional casting and CAD/CAM milling. Restorations were assessed according to FDI clinical evaluation criteria with respect to esthetic, functional, and biological outcomes during follow-up appointments.Clinical evaluations took place at baseline (2 days after luting) and following 3, 6, 12, and 18 months after luting.
