Veterans Administration Cooperative Studies Project No. 147. A precementation comparison of metal ceramic restorations made with a gold-containing alloy or alternative alloys.
This analysis compared the precementation quality of metal ceramic restorations made from different alternative alloys after they had been returned from the central dental research laboratory. Ticon, Micro-Bond N/P2, Ceramalloy II, and W-1 materials were evaluated by use of 11 well-defined criteria and for overall performance. The evaluations were compared with those of Olympia, a gold-containing alloy, which served as the control. The results showed statistically significant differences between Olympia alloy and some of the alternative alloys for six of the 11 criteria. These differences, however, were not sufficient to be considered clinically significant (clinically detectable). In the comparison of their overall performances no statistically significant differences were found.
