The temporaries are made to protect the underlying tooth structure as the final porcelain restorations are being fabricated in the ceramist's laboratory. Veneer and crown temporaries should look good. Finely made temporaries should have perfect marginal adaptation to the underlying teeth. The surface should be well polished to resist staining, since the material is simply an acrylic form. In our office we spend a significant amount of time on the temporaries because they should not affect the lifestyles and career demands of our patients. In other words, at the very least, no one should notice at conversational distance that your teeth are in temporaries.
Furthermore, well made temporaries will also allow the gum tissue to remain in perfect health. This clinical result will allow the dentist to ensure a perfect bond between the porcelain and the teeth at the final cementation process. If the gum is inflamed from improper fabrication of the temporaries, the end result may be compromised due to possible contamination of fluid and blood from bleeding gum around temporaries.
The term "temporaries" is misleading in a sense that they are only meant for short-term use. In fact, all details considered in the final restorations must be taken in to consideration with the ... "temporaries".
Here is a photo of a sample case of one of our patients, taken on the day she returns for her final porcelain restorations. Note that the four front teeth are bonded with acrylic temporaries.
