I have an implant on the #10 tooth and my dentist can't find the right restoration for me (screwed in, not permanently cemented). The first try was zirconium base with porcelain finish, but it was too opaque and didn't match my natural teeth. The second was a composite resin tooth, but again looked fake. Now he suggests a "traditional" metal-porcelain restoration, but I am afraid that the metal will show through my gum line and it will be too opaque again. Please help! I'm getting desperate!
