In the clinical environment, an artistically contoured and well-marginated provisional restoration nurtures the gingival tissues with proper marginal seal and emergence profiles during the interim phase of treatment. A provisional matrix can be fabricated from the pre-operative stone model / composite mock up using a clear plastic stent material and a thermoplastic suck down device. After the teeth are prepared (Figure 1), Tuff-Temp Plus is dispensed into a matrix and placed on the prepared teeth for approximately two minutes. Once the Tuff-Temp Plus provisional shell is recovered from the matrix, a sharp lead pencil is used to delineate margins and the contact zones proximally, so they are not accidentally damaged during the trimming process.
