Objective:
To evaluate the novel locally manufactured osteosynthetic titanium bone mini plates used for mandibular fracture fixation, and to compare it with an international brand to have an alternative to expensive plates.
Methods:
The study was conducted at National University of Science and Technology from Jan 2013 to June 2013. Local and German brands of osteosynthetic titanium bone mini plates were studied electrochemically through Tafel extrapolation curves using Gamry® electrochemical framework in modified simulated body fluid prepared with pH 7.4 at 37OC. For bacterial adhesion, staphylococcus aureus bacterial culture of 50 l was used with an OD600 of 1.0 corresponding to approximately 1.79×109 cells ml-1. Data was analysed using SPSS 20..
Results:
Corrosion resistance behaviour of local and German plates was not significantly different (p>0.05), but in case of bacterial adhesion the local plates showed significantly low adhesion compared to the imported material (p<0.05). Overall, the biocompatible properties of local plates met international brand qualities.
Conclusions:
Electrochemical corrosion and bacterial adhesion of local osteosynthetic maxillofacial bone plates matched the quality of an international brand.

What is an Electrochemical Gradient?
The chemical gradient relies on differences in the abundance of a substance on the outside versus the inside of a cell and flows from areas of high to low ion concentration. In contrast, the electrical gradient revolves around an...
