It is essential to observe the following points when designing Vectris frameworks:
1. Designing the silicone matrix
2. Designing the framework for single crowns
2.1 Anterior crowns
2.2 Posterior crowns with a flat occlusal preparation
2.3 Posterior crowns with a deep occlusal preparation
2.4 Posterior crowns without supporting cusps
3. Designing the pontic
3.1 Pontic
3.2 Joint face of the connector
3.3 Pontic/abutment contact layer
4. Trimming the margins of Vectris frameworks
5. Placing Vectris Pontic into the Transil matrix
The indicated numbers of Pontic strips are reference values and may differ depending
on the situation in question.
