title: Fatigue life of porcelain repair systems.
abstract: Eight intraoral porcelain repair systems, ie, Oral Ceram-Etch (Gresco), Scotchprime (3M), Rocatec (ESPE), Command Ultrafine (Kerr), Silistor (Kulzer), Clearfil Porcelain Bond (J Morita), All-Bond (Bisco), and Monobond S (Vivadent) were used in this study. The control specimens consisted of unetched porcelain surfaces onto which a resin composite was polymerized without the use of an adhesive. Load fatigue was used as the testing method to simulate the repetitive action of mastication. The peak stress applied to each test specimen was 1500 psi (10.34 MPa), and an upper limit on the number of load cycles applied to any specimen was set at 2,000,000 cycles. Statistical analysis revealed two significant subsets. Only Clearfil Porcelain Bond and All-Bond did not fail before reaching the 2,000,000-cycle upper limit.
