Summary

In this study, the production of ceramic-based dental implant materials were investigated. Composition of dental implant materials studied was in the range of 55–75 % calcined bone powder, 25% kaolin and 0–20% zirconia. The powders were milled and mixed using wet ball milling technique with alumina balls for 24 hours. After milling, powders were dried in an oven at 120°C for 24 hours. Then dried powders were sieved through −63 μm and polymeric binder + surfactant added to the batch composition which was about 18 % of the mixture. The batch were mixed thoroughly at 90°C during the binder addition.

It was observed that samples could quickly hardened when cooled after having final shape. After shaping, binder was removed from implant by heating at 130°C for 5 hours in very fine absorbant powder. Finally, sintering was carried out at 1200°C for 2 hours. Samples prepared from the studied compositions were shown to be easily formed into required implant's shape.
