Abstract

A Technique to Increase Retention of all Metal and Porcelain Fused to Metal Crowns to Cast Post and Core Restorations

Retention prevents dental restoration from being dislodged along its path of insertion. However, classic retentive factors are not always possible to implement in fixed prosthodontics. Therefore, it may be helpful to utilize non-conventional methods to enhance retention in situations where retention can’t be obtained from primary and secondary retentive factors. This article describes a technique to increase crown retention to cast post and core by using a horizontal retentive post to lock the crown to the cast post and core.
