Posts are normally used to aid core retention and to provide tooth support, although a significant minority question the use of posts in the latter role. A direct relationship is thought to exist between the quantity of sound tooth structure and tooth strength and care is required when preparing teeth to accept posts. Post configuration is of over-riding importance in determining retention and support and the effect on retention of small increases to post length should not be over emphasized. Because accurate post fit is important to maximize both retention and support, direct fabrication techniques using matched post/reamer systems are recommended.
桩通常用于辅助固位核并提供牙齿支持，尽管少数人对桩在后者作用中的使用提出质疑。完好牙体组织的量与牙齿强度之间被认为存在直接关系，在预备牙齿以容纳桩时需要谨慎。桩的形态在决定固位和支持方面至关重要，不应过分强调桩长度的小幅增加对固位的影响。由于精确的桩适配对于最大化固位和支持都很重要，因此建议使用匹配的桩/扩孔钻系统的直接制作技术。
