An in vitro study was performed evaluating three post and core techniques with and without full crown coverage on extracted mandibular molar teeth. The materials evaluated were amalgam, composite resin, and stainless steel posts, and a combination of cast-gold and stainless steel posts. The results indicate that the method of post and core technique may not be as significant as the placement of full coverage cast-gold crown restorations with sound design and placement of margins beyond the buildup restoration.
进行了一项体外研究，评估在拔除的下颌磨牙上采用和不采用全冠覆盖的三种桩核技术。评估的材料有汞合金、复合树脂和不锈钢桩，以及铸金和不锈钢桩的组合。结果表明，桩核技术的方法可能不如设计合理且边缘位于核修复体之外的全冠铸造金修复体的放置重要。
