Figure 33: My assistant likes to place dental floss around bridges with
ovate pontic sites to ensure excess cement is removed from around the
bridge. This is especially important when you have prepared an ovate
pontic receptor site, as we have done here. Cement that stays in the site
of the surgery will have an adverse effect on the tissue.
Figure 34: The BioTemps provisional has been cemented into place and
all of the excess cement has been removed. My assistant left a small
open embrasure between tooth #8 and #9 to ensure we don’t blunt the
papilla. Knowing patients won’t use a floss threader around temps, I like
to leave the gingival embrasures open and have them swish with Tooth
and Gums Tonic ® (Dental Herb Company; Boca Raton, Fla.) to keep the
area clean.
Figure 35: A look at the opposing model as captured by the IOS Fast-
Scan scanner. Using the two scans we took, we are able to clearly visualize
the facial, lingual and incisal characteristics. Dental assistants in
all states can take this scan because they’re already permitted to take
opposing alginate impressions, for example.
Figure 36: Here is the prepped arch as captured by the IOS FastScan
scanner. In addition to capturing the information of the abutment teeth,
the scanner was also able to accurately read the internal contours of the
ovate pontic receptor site. Notice how the incisal half of the preparations
angle toward the lingual because of the position of the 1.5 mm
depth cut.
