Building up tooth preparations for full crowns -- 2000

Article Abstract:

Dentists may not need to build up teeth in preparation for a crown as they did in the past. A crown is an artificial tooth shell that is placed over an existing, decayed tooth. The existing tooth must be built up to support the crown. This is not always necessary if the crown is only used to cap an existing tooth. But buildup may be necessary if the tooth will be used to support a denture. Advances in dental resins make extensive tooth buildup unnecessary.

Seating nonmetal crowns or fixed partial dentures with resin cement

Article Abstract:

Nonmetal crowns and fixed partial dentures can be effective in tooth restorations if the right resin cement is chosen and applied correctly. Resin cements are necessary for all-ceramic and polymer restorations because they provide additional strength. Autocured, light-cured, and dual-cured resins are each appropriate for different clinical applications. Resin curing is inhibited by oxygen exposure, so resin cements must fully polymerize before they are wiped. Sealing or desensitizing agents may be necessary to prevent tooth sensitivity following these restorations.
