在大多数哺乳动物和极少数爬行动物中，精确牙齿咬合的进化导致由于进食时产生的压力而形成功能性咀嚼表面的能力。人们对此类牙齿复杂的牙齿结构及其自磨损性质的生物力学知之甚少。我们的研究小组由古生物学家、进化生物学家和工程师组成，制定了一项协议：（1）确定现存和化石类群中磨削牙列的组织学构成； (2) 确定组织与磨损相关的材料特性； (3) 使用专门为牙科应用开发的三维 Archard 磨损模型，确定这些特性如何与导致牙科功能的组织间生物力学相关； (4) 在系统发育背景下分析这些数据，以推断与进食相关的进化模式。最后，我们讨论了受古生物学启发的研究中出现的工业应用。
In most mammals and a rare few reptilian lineages the evolution of precise dental occlusion led to the capacity to form functional chewing surfaces due to pressures generated while feeding. The complex dental architectures of such teeth and the biomechanics of their self-wearing nature are poorly understood. Our research team composed of paleontologists, evolutionary biologists, and engineers have developed a protocol to: (1) determine the histological make-up of grinding dentitions in extant and fossil taxa; (2) ascertain wear-relevant material properties of the tissues; (3) determine how those properties relate to inter-tissue-biomechanics leading the dental functionality using a three-dimensional Archard's wear model developed specifically for dental applications; (4) analyze those data in phylogenetic contexts to infer evolutionary patterns as they relate to feeding. Finally we discuss industrial applications that are emerging from our paleontologically-inspired research.
