Root canal retained restorations: 1. General considerations and custom-made cast posts and cores

Area of Science:

• Dental Materials Science
• Restorative Dentistry
• Endodontics

Background:

• Root canal treated teeth often require restorations for structural integrity.
• Post-retained restorations are crucial for function and aesthetics in endodontically treated teeth.
• Selecting the appropriate post system is vital for long-term success.

Purpose of the Study:

• To review general considerations for root canal retained restorations.
• To discuss factors influencing post retention and tooth reinforcement.
• To describe clinical procedures for fabricating cast posts and cores.

Main Methods:

• Literature review of factors affecting post retention.
• Comparative analysis of cast versus wrought posts.
• Description of direct and indirect techniques for cast post and core fabrication.

Main Results:

• Retention is influenced by post type, design, and luting agent.
• Cast posts offer customization but require specific techniques.
• Tooth reinforcement strategies are essential for preventing fractures.

Conclusions:

• Careful treatment planning is necessary for successful post-retained restorations.
• Understanding material properties and clinical techniques optimizes outcomes.
• This article serves as a foundation for subsequent discussions on prefabricated systems.
