Resin shear bond strength to porcelain and a base metal alloy using two polymerization schemes

Comparison of Repair Methods for Ceramic‐Fused‐to‐Metal Crowns

“…DESPITE THE INCREASED effort to improve the bond between ceramic materials and metal substrate, fractures of ceramic‐fused‐to‐metal (CFM) restorations still occur. The reasons for fractures are frequently repeated stresses and strains during chewing or trauma 1–6 . Repairing CFM in vivo can increase the clinical longevity of the failed restorations, thereby offering the patient and the dentist a cost‐effective alternative to replacement; however, the repair of fractured CFM crowns represents a potential clinical challenge, particularly when the metal substructure has been exposed, and when bonding of resin to metal alloy is required 4,7 …”

Effects of Surface Treatments and Cement Types on the Bond Strength of Porcelain‐to‐Porcelain Repair

“…These results were based on the use of a single ceramic primer, and cannot be generalized to other primers. The repair bond strength of metal ceramic restorations has been reported in the range of 6 to 35 MPa . The minimal SBS recommended for clinically successful performance is 13 MPa.…”

“…Metal ceramic restorations have been widely used in dentistry for several decades due to their predictable strength and performance . However, failure of these restorations may occur when the veneering porcelain fractures, compromising esthetics and function . Previous clinical studies on metal ceramic crowns and partial fixed dental prostheses reported that fractures of veneering porcelain occur 2.38% to 8% of the time .…”

Reparación intraoral de una prótesis parcial fija metal-cerámica de seis unidades con resina compuesta: Relato del caso

“…Clínicamente las fracturas de restauraciones metal-cerámica pueden generar tres condiciones del sustrato: fractura de porcelana sin metal visible, con leve exposición metálica o fractura con sustancial exposición de estructura subyacente (7) . Para la unión resina-metal y resina-porcelana, en busca de una adhesión satisfactoria, se reportan varios sistemas de retención mecánica y unión química (16) .…”
