Preparation Guide
In dentistry, just as in construction, a good foundation is the basis for a high-quality, long-lasting restoration. Inadequate reduction or poor preparations are one of the leading causes of crown and bridge fractures and failures. Careful attention to the recommended clearances and reductions will ensure a highly aesthetic restoration that will seat quickly with minimal adjustments.

Fortress Veneers - Preparation Techniques
- A dept cut is accomplished to ensure a uniform preparation and porcelain thickness.
- The remaining enamel surface is uniformly prepared to match the initial depth cut.
- Proper chamfer preparation is vital in enabling an adequate bulk of porcelain.
- The interproximal preparation is extended from the gingival chamfer margin into the proximal space.
- During the incisal edge preparation, the bur is angled slightly to ensure a proper preparation is achieved.
- Undercuts and sharp line angles are eliminated and a deep chamfer is created during the preparation of the lingual chamfer.
