Fractal Measure and Microscopic Modeling of Osseointegration
dos Santos, Leonardo Cavalcanti Bezerra / Carvalho, Alessandra de Albuquerque Tavares / Leão, Jair Carneiro / Duarte Neto, Paulo Jose / Stosic, Tatijana / Stosic, Borko
In this study, the process of osseointegration on titanium implant surfaces with different physicochemical treatments subjected to a simulated corporal fluid submersion was evaluated using the concept of fractal dimension. It was found that different treatments led to rather different calcium phosphate crystal growth patterns, with fractal dimension ranging from 1.68 to 1.93. The observed crystal patterns may be explained by a general deposition, diffusion, and aggregation growth mechanism, where diffusing particle sticking probability plays a fundamental role.
