Artificial dental root material has been very important among all bio-materials. In this study, two different ways of aluminum coating are used. One is wire frame spraying, and the other is atmospheric plasma spraying. The affinity, stability, and connectivity of aluminum toxins with sprayed coating are used and the possibility for applying ways are examined. Acute toxic tests are performed clinically. Both in-vivo and in-vitro experiments are performed on a dog, and the results showed that aluminum sprayed coating is good as an artificial dental root material.
