Insufficient curing.
Inadequate polymerization.
1. Check compatibility of curing light.
2. Check curing cycle.
3. Check minimum irradiance.
4. Cure each area of each increment for the recom-
mended curing time.
5. Check distance to surface to be cured.

3.1.7 Finishing and polishing
1. Contour the restoration using finishing burs or diamonds.
2. Use Enhance finishing devices for additional finishing.
®
3. Prior to polishing, check that surface is smooth and free of defects.
4. For achieving a very high luster of the restoration, we recommend
Enhance PoGo , finishing and polishing instruments or Prisma

Gloss™ Regular and Extrafine polishing paste.
For contouring, finishing, and/or polishing, follow the manufactur-
er's Directions for Use.
All shades of TPH Spectra

storative are radio-opaque, with a 1 mm radio-opacity equivalent to
2.0 mm radio-opacity of aluminum. Aluminum has a radio-opacity
equivalent to that of dentin. Thus 1 mm of material having a ra-
dio-opacity equivalent to 1 mm of aluminum has a radio-opacity
equivalent to that of dentin.
3.2 Indirect restoration: Inlay, onlay or veneer
3.2.1 Shade Selection
Final desired shade selection should be accomplished prior to tooth
preparation. Refer to the Shade Selection section above.
3.2.2 Preparation
Design requirements are essentially a conventional preparation. Round-
ing of internal angles and refinement of the cavo-surface margin for en-
hancement of enamel bonding and finishing procedures is recommended.
