Transfer to the mock-up

We created a silicone key of the vestibular surfaces with the help of the wax-up and applied a thin layer of composite material into the key using a spatula (IPS Empress Direct) (Fig. 3). Once light cured (Bluephase® with Polywave® LED), the resulting composite veneers for teeth 15 to 25 were placed on the model and stabilized with wax (Fig. 4). Once the wax-up was finalized, it was duplicated and cast in stone. We created a silicone key from this model to assist the dentist in the preparation of the teeth. The silicone key was created in two steps using two different silicone materials, one with a high hardness (Silico Dur, Cendres + Métaux) and the other with a low hardness (3M ESPE Express). The silicone key served to create the mock-up and the temporaries.

Tooth preparation and data transfer to the lab

The mock-up was inserted with the help of the silicone key and the surface texture was reworked using a polishing system (Astropol®) (Fig. 5). The esthetic effect was validated with photographs and videos. The patient could also inspect the pictures (Figs 6 and 7). Then, the teeth were prepared using a ball-shaped bur whilst the mock-up was in place (Galip Gurel 2003) (Fig. 8). This procedure meets the requirements of minimally invasive dentistry. An impression of the prepared teeth (Fig. 9) was taken using an intraoral scanner and the temporaries were fabricated with the help of the silicone key.

At this point, the dentist is required to take two optical impressions: first, an impression of the prepared teeth and, second, an impression of the temporaries in the mouth. In addition, a conventional silicone impression of the prepared teeth is taken. The dental technician will use this ...
