This study assesses the repair procedure for porcelain fracture and involves fitting and bonding a porcelain material over the original damaged crown. To simulate the situation, a test sample was designed to simulate composite bonded porcelain-to-porcelain. A total of 120 samples was prepared and the shear bond strengths were tested. Three composite resins, two porcelain combinations, and two storage-time intervals were used. Significant differences were found among the three types of composite resins. Porcelain combinations did not affect the results. Furthermore, the mean bond strength was higher at 45-day storage than at 90 days.

D003776 Dental Porcelain A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water.
