Crowns and other extra-coronal restorations: Cores for teeth with vital pulps
R W Wassell1, E R Smart2 & G St. George3
- Core placement nowadays demands more use of adhesives (coupled with retentive cavity preparation) and less use of pins
- It is good practice to remove existing restorations of unknown provenance to facilitate cavity inspection and ensure core retention
- Cores act either as a simple space filler or a structural build-up. The less tooth structure the greater the mechanical demands on the core, the material for which must be chosen carefully
- Dentists placing pins need to be aware of how to prevent and manage pin placement problems
Crowns and extra-coronal restorations:
- Changing patterns and the need for quality
- Materials considerations
- Pre-operative assessment
- Endodontic considerations
- Jaw registration and articulator selection
- Aesthetic control
- Cores for teeth with vital pulps
- Preparations for full veneer crowns
- Provisional restorations
- Impression materials and technique
- Try-in and cementation of crowns
- Porcelain veneers
- Resin bonded metal restorations
Abstract
Cores for teeth with vital pulps is the seventh in the series of crowns and other extra-coronal restorations. A core is defined as 'that part of a preparation for an indirect restoration consisting of restorative material'. This article questions the need for routine pin placement and addresses the following issues – removal of existing restorations, the need for a core, core materials, core retention, and problem solving.
