摘要 |
The invention relates to dental constructions such as bridges, crowns and the like comprising a metal core and porcelain or other tooth simulating material bonded thereto, and to dental alloys having good physical strength, corrosion resistance, workability and ability to bond to porcelain. The dental alloys have a base cost of substantially less than gold but are equal to or better than gold for many dental applications. The alloys are also useful in dental applications not requiring bonding to porcelain or plastic as in the preparation of metal inlays or onlays. |
