DENTAL CERAMIC COMPOSITION FOR TITANIUM |
摘要 |
A dental ceramic material that can be fused with high bonding strength to dental prostheses including crowns, bridges, or prostheses parts made of titanium or titanium alloys is disclosed. The ceramic material requires the presence of B2O3 at between 8 and 17 weight percent and this concentration range is directly responsible for the high bonding strength attained. In addition, the material fulfills the esthetic requirements necessary to achieve natural appearing tooth colors and stains in dental restoratives when bonded to titanium or titanium alloys. The ceramic material may be prepared as a dental powder or as a suspension or paste and if the suspension or paste contains polymerizable compounds the suspension or paste can be selfcured or cured by visible light. |
