Abstract
The degradation behavior of magnesium-based implants with 0.8wt% calcium and different surface conditions for 3 and 6 months was investigated. The study used MgCa0.8 implants of 3mm × 5mm cylinders receiving different surface machining treatments. The sand-blasted implants were produced from smooth implants using a downstream irradiation process. Twenty-four female, adult New Zealand white rabbits with an average weight of 3.5 kg were used for the study and kept in standardized cages with free exercise daily. The degradation of MgCa-implants with various surface modifications was examined during the study. It was observed that the hole-shaped degradation started at the thread flank affected the core particles of the screw-shaped implants. The study also found that smooth implants showed the best integration into the bone compared to sand-blasted and threaded cylinders.
