Abstract

The use of the hot injection technique for the production of porcelain/zirconia based dental structural elements has been spread over the years. However, suitable parameters should be used for the production of components, providing them high mechanical properties. Therefore, proper optimization of the process allows producing materials with high densification and thus minimizing defects related to their confection. Thus, the aim of this study was to evaluate the best parameters for the preparation of powder pure porcelain samples of subsequent production of zirconia-reinforced porcelain at different proportions. The results showed that the powder porcelain injection is influenced by stage time conditions, sintering temperature and injection force. The powder porcelain injection must be made at sintering temperature exceeding 1000°C, and the stage time should not be less than 20 minutes.
