Quick and Easy Single Tooth Provisionals
When I got out of school, I started using a pre-operative alginate, poured it in Snap Stone and fabricated a silicone matrix. I prepared the tooth and made a quick post preparation alginate, which was handed off to another assistant, who poured it up and made the temporary indirectly while my other assistant placed retraction cord and a final impression was made.
As newer provisional materials are available to be used directly in the mouth, my technique has adapted. I was resistant to making the change at first but now I realize it’s faster, more predictable and requires little to no adjustments.
Now my assistant takes an inexpensive triple tray and loads it with an alginate alternative (AlgiNot) and has the patient close for approximately one minute and then we remove and trim any excess with a #12 Bard Parker blade. At the end of the preparation, we load in a Bis-Acryl (Venus II, Exacta Temp, etc.) and have the patient close back into the pre-operative matrix. We wait for approximately one minute and remove. This will often produce a temporary that has little to no flash, and has great occlusal and proximal contacts.
While the material finishes setting, we place cord and take a final impression. The provisional requires little to no adjustments and is easy for assistants to master in short period of time. On top of that, we can keep the pre-operative triple tray handy until the final restoration is seated, just in case the patient loses the provisional. At times, we have even sent it with our patients that are traveling out of town.
The next time you make a provisional you might want to try something different.
