| Research Abstract |
To realize all-ceramic restorations applied with zirconia, it is important of development of surface modification method for zirconia in order to improve the bonding strength to veneering porcelains, the bonding strength to cements, and biocompatibility. Bonding strength of zirconia with surface treatment such as sandblasting, acid etching, silane coupling, hydrothermal treatment, and glass coating were determined to the veneering porcelains and resin cements, and their biocompatibility were evaluated. The results demonstrated that zirconia showed different behavior from those of conventional dental ceramics. It indicates that new surface treatment method specialized to zirconia should be developed.
