Transferring the pontic to the duplicate model
Transfer the fully contoured pontic to the duplicate model and use a small amount of wax to hold it in place. Block out the
basal surface of the pontic using laboratory silicone (Sil-Tech) in order to ensure that the following Transil matrix can be
removed effortlessly. It is important to block out this area because this determines the way in which the Vectris Frame is
wrapped around the Vectris Pontic. The portion of the basal surface that is in contact with the laboratory silicone should
not be too wide. It is advisable to follow the following instructions to transfer the pontic to the duplicate model:
1. Reduce the basal surface of the duplicate model and prepare retention
2. Transfer the pontic to the duplicate model and use a small amount of wax to hold it in place
3. Block out the reduced basal surface using laboratory silicone (Sil-Tech)
4. Reduce the blocked out area by means of a scalpel or bur
Reduce the basal surface of the duplicate model and transfer the pontic to the model.
Block out the reduced basal surface with laboratory silicone and then reduce the blocked out area.
The basal surface should not be too wide. Pontic on the duplicate model after completion of the transfer process.
