| Outline of Final Research Achievements |
Dental zirconia for clinical use has increased instead of cast metal, because of its stable characteristics. On the other hand it is said that easily failed from abutment tooth. Silica coating layer could be found on the dental zirconia using a silica improved sandblaster at my early experiment.This result has suggested the possibility of enhancing adhesion to the dental zirconiaby the silane coupling treatment. However, combinations of surface treatments and silane coupling treatments were not observed that improved the adhesion to dental zirconia. This result means that the surface of dental zirconia is very hard and its composition is very complex to investigate regular method.
