The restoration of endodontically treated teeth. Part 2. Posts

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.
