粘合剂技术自五十多年前引入以来发展迅速。今天，蛀牙或骨折的牙齿可以通过使用粘合剂技术进行微创和几乎不可见的重建。然而，临床寿命有时仍然太短。虽然水吸附被认为是生物材料-牙齿结合的主要不稳定因素，但实际的界面降解机制还远未了解。与牙釉质和牙本质结合的基本机制基本上是基于交换过程，其中从牙齿硬组织去除的矿物质被树脂单体取代，所述树脂单体在聚合后在所产生的孔隙中微机械地互锁。除了通过杂交的微机械互锁之外，功能单体/聚合物与牙齿基质组分之间的额外化学相互作用的潜在益处最近重新受到关注。在这篇综述论文中，我们重点讨论了生物材料-硬组织界面的化学相互作用如何提高粘结耐久性。
Adhesive technology has evolved rapidly since it was introduced more than fifty years ago. Today, decayed or fractured teeth can be reconstructed minimally invasively and nearly invisibly using adhesive technology. However, the clinical longevity is sometimes still too short. Although water sorption is thought to be the main destabilizer of the biomaterial–tooth bond, the actual interfacial degradation mechanisms are far from understood. The fundamental mechanism of bonding to enamel and dentin is essentially based on an exchange process, in which minerals removed from the dental hard tissues are replaced by resin monomers that upon polymerization become micro-mechanically interlocked in the created porosities. In addition to micro-mechanical interlocking through hybridization, the potential benefit of additional chemical interaction between functional monomers/polymers and tooth substrate components has recently regained attention. In this review paper, we focus on how chemical interaction at the biomaterial–hard tissue interface can improve bond durability.
