Figure 28: Even though we know we reduced the proper amount<br />
on the incisal, facial and gingival surfaces, there are interproximal<br />
areas where it is impossible to place depth cuts. This makes it<br />
prudent at this point to try on the BioTemps ® prep stent (<strong>Glidewell</strong><br />
Laboratories) for the BioTemps Provisionals we will be placing<br />
to make sure we have reduced enough in all dimensions. The<br />
BioTemps are prepped as thin as possible, so there should be<br />
plenty of clearance, except maybe interproximally.<br />
Figure 29: You can also try on the stent that was made with the<br />
BioTemps on the model. While the first prep stent serves to check<br />
interproximal reduction, this one shows your preps in relation to<br />
the BioTemps, which act as the proposed final restorations. Just<br />
as important, this stent can save you if something goes wrong<br />
with the BioTemps; simply fill this stent with Luxatemp ® Ultra<br />
(DMG America; Englewood, N.J.) and place it on the teeth for a<br />
direct temporary.<br />
Figure 30: The rubber really meets the road when you try in the<br />
BioTemps for the first time. If you have followed every step detailed<br />
so far, 9 times out of 10 the BioTemps will drop into place passively.<br />
This is our objective. If you skip the first stent that was made on<br />
the BioTemps prep model, the BioTemps may not passively seat.<br />

Figure 31: Here we have placed the Luxatemp Ultra into the<br />
BioTemps and are seating them on the preps. I insist on Luxatemp<br />
Ultra because it is the only bis-acryl temporary material that goes<br />
through a doughy stage, which allows me to pump the BioTemps up<br />
and down in it as though it were methyl methacrylate — other bisacryl<br />
materials go from soft to hard too quickly for this technique,<br />
potentially locking the BioTemps into place too soon.<br />
