ABSTRACT
Objectives: In this study the conditioning of two mandibular mini plates was done in modified simulated body fluid at 37°C
Study Design:An experimental study
Place and Duration of Study: This study was conducted at in the laboratory of National University of Science and Technology from March to Mach 2013
Materials and Methods: The two brands of mini bone plates were selected, one imported from Germany while other was manufactured in local industry. The modified simulated body fluid [m-SBF] was prepared by dissolving reagent in deionised water. The conditioning was done at 1, 7, 14, 21 and 28 days. The surface changes produced after conditioning were analyzed under scanning electron microscope [SEM]. The energy dispersive X-ray [EDX] analysis was also used to identify compositional variations of the MPP and MPGsurfaces
Results: The SEM revealed almost similar changes in body fluid environment in both plates however the surface of MPG was anodized while no anodization was done on MPPs while in EDX analysis the main elements found were Ti[Titanium] and O [Oxygen] in MPP and MPG. O was more initially then gradually decreases with passage oftime in case of MPG while in MPP the O was in low concentration in early conditioning time and then it decreased
Conclusions: The surface of MPG was anodized while no anodization was done onMPPs
