I had a discussion with a client about a technique he was taught for promoting tissue adherence to implant restorations. Apparently, polished, unglazed, zirconia is a great surface for the gingiva to adhere to. I like to use custom abutments for my screw retained restorations, but I also place the margins much closer to the implant than I would if it was a cemented restoration. We are going to try and do this on his future restorations. I am just going to polish the sub g zirconia and glaze the supra g zirconia. He was asking about not using glaze at all, but I told him that unglazed zirc has a different look. It may be acceptable in the posterior region to not glaze the zirc so i am gong to send him an unglazed and a glazed zirc crown on his next case so he can compare. Here's and article with more detail about the science behind this technique.
