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 easily. It is important to block out this area since it will determine the way in which the Vectris Frame wraps
around the Vectris Pontic. The portion of the basal surface that is in contact with the laboratory silicone should not be too
wide. The following instructions should be observed when transferring 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 hold it in place with a small amount of wax.
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 basal reduction with laboratory silicone and then reduce the blocked out area.
