Hi Alan: if I have lots of tooth structure and the preps are not in enamel ( these were in cementum and dentin) in many areas , I will choose GI.
IT is easier to cement these with GI I must admit and I do like the fluoride. In addition I wasnt worried about them coming loose.
GOod point though and I dont have any qualms about using Variolink, just didnt do it.
I know some guys bond everything in. I rarely bond the Empress 2 or Procera crowns (heck can you even bond Procera into place??)
Great question and I think there will be a variety of answers.
You got me thinking.
