Mineralization of Titanium Substrates with different Structures and Surface Finish, Pre-incubated in Albumin

摘要

A study is reported on the influence of surface morphology, chemistry and albumin adsorption on the in vitro mineralization of titanium.Albumin is the most abundant protein in plasma and was chosen as a pre-incubation medium for titanium substrates previously conditioned by mechanical, thermal and chemical treatment. Subsequent mineralization studies were performed in carbonated simulated inorganic plasma (CSIP) physiologically buffered with CO_2/HCO_3~-. The results indicate that surface morphology and albumin adsorption contribute to the development of a B-carbonated apatite deposit and, furthermore, that the buffer system may alter the role of albumin in mineralization.
