摘要: The mechanical properties of resin-modified "hybrid" glass-ionomers, for both restorative and liner/base applications, were assessed by a flexural test compared with those conventional acid-base glass-ionomers. Flexural strength, modulus, the modulus resilience determined 30 minutes after mixing, at 24 hours 3 months aging in distilled water 37 degrees C. With microscope SEM observations, comparison marginal breakdown was made between glass-ionomer restoration bovine cavities, cyclic loading steel balls. It found that glass-ionomers stronger, more flexible, resilient than This accord finding less surface deterioration occurred analogue. For some materials progressively improved months, while others showed no improvement or even deteriorated.
