I often use Fynal, a temporary cement by Caulk, to place my full coverage provisionals. One of the challenges with the material is the bright white color. When the provisionals are of adequate thickness or they are posterior and esthetics is less critical this can be easily overlooked. In the anterior patients have been bothered by the white line at the margins, and show through at the cervical where the material is thin. I have also had situations where in a 1mm reduction prep on maxillary anterior teeth the white color can make the provisionals too high in value.
Recently I learned a way to correct for this in clinical situations where it is an issue. You can purchase or ask your laboratory technician to get you some ochre porcelain powder. As you are mixing the Fynal you add a very small amount of the powder, the color will get warmer and warmer from beige to a tan. This then will disappear under the provisional material, not be noticeable at the margins, and can be used to warm an anterior provisional that is too high in value.
I have followed this procedure on the last few anterior provisionals I have seated, and I think is is fantastic. So much so, that I’m going to do it as a routine practice, and try it with some of the other white temporary cements we have in the office.
