Hi everyone, I have a case with 2 centrals, one is natural dentition prepped and the other is an ASTRA implant. Dentist requests Emax crowns. Is it safe to have an full mono emax crown ( cut back and layer incisal only) on a cast on abutment? I'm concerned about the strength on of the Emax crown on the metal substructure on an implant since there is zero give with the implant. I also plan to opaque the cast on to hide the metal before I press the emax. Anyone have any thoughts on this?
