Abstract:
A 5-year clinical comparison between silver palladium alloys (Albacast and Ney 76) and gold alloy (Firmilay) was conducted. Clinical evaluations for the castings of these materials placed in the same patients, were recorded immediately after cementation, at 3 months, 6 months, 1.5 years, 3 years, and 5 years. The changes in surface tarnish, discoloration, polish, and plaque accumulation was compared. The results indicated that gold alloys responded slightly better than Ney 76 alloy, but similar to Albacast alloy with adequate correlation between the four criteria evaluated.
