Darin O'Bryan In Part 2 of this series, I showed how to prepare the teeth fast and predictably to get 90% of the preparations done in minimal time. Now we need to transfer the wax up to the patient to verify the esthetics, mid line and function. For this we use a vacuform stent made from duplicate stone model of the wax up.
The vacuform stent is filled with a self curing bisacryl material and then seated on the preparations.
The excess around the gingival margins is removed with a micro brush. The vacuform stent is trimmed to gingival margin of the wax-up. This way once the excess is cleaned there will be less need for trimming around the mock up.
The mock up is then trimmed with finishing burs to accentuate the embrasures and line angles. Once this is done, it is time to start imaging each individual unit and finalizing the preparations of each tooth.
The incisal embrasures are not as important since we will be refining them once we have prepared the tooth for the final restoration and we are ready to image.
