The restoration of endodontically treated teeth. Part 2. Posts.

A J Hunter, A M Flood

    Australian Dental Journal
    |February 1, 1989
    PubMed
    Summary

    Dental posts aid core retention and tooth support, but their role in support is debated. Proper post fit and configuration are crucial for maximizing retention and support, with direct fabrication techniques recommended.

    Area of Science:

    • Restorative Dentistry
    • Dental Materials Science

    Background:

    • Dental posts are utilized for core retention and to support restorations.
    • The role of posts in providing tooth support is a subject of ongoing debate.
    • The amount of remaining sound tooth structure directly influences tooth strength.

    Purpose of the Study:

    • To evaluate the importance of post configuration and fit for retention and support.
    • To emphasize the relationship between tooth structure and overall tooth strength.
    • To recommend optimal techniques for post preparation and fabrication.

    Main Methods:

    • Review of existing literature on post systems and their biomechanical behavior.
    • Analysis of factors influencing post retention and tooth support.
    • Evaluation of direct fabrication techniques versus indirect methods.

    Main Results:

    • Post configuration is a primary determinant of retention and support.
    • Minor increases in post length have a limited impact on retention.
    • Accurate post fit is essential for optimal retention and support.

    Conclusions:

    • Careful tooth preparation is necessary when placing posts.
    • Direct fabrication using matched post/reamer systems is recommended for accurate fit.
    • Optimizing post design and fit is key to successful post-endodontic restorations.
