I had tooth 7 implant done and I have to decide which Crown is better for my front tooth. My old dentist suggested zirconia abutment with e-max crown. I moved to another state and my new dentist tells me that zirconia abutment will be too white and hard to make it look good and the e-max attached to it may not be strong and may break. He recommended metal abutment with empress crown. What is your opinion? Please help me.
