报告内容摘要：

Caries, which lead to partial or total loss of teeth, influence almost 100% adults and 60-90% of school children. To restore the function and appearance of teeth, dental restorations (including dental crowns and dental implants) have been adopted as a common treatment. This talk will present the results of a combined experimental and computational study of mechanics and materials that are relevant to applications in dentistry. Inspired by natural teeth, functionally graded nanocomposite materials are developed for novel designs of dental crowns that are more resistant to cracking under contact loads; Strain distribution in alveolar bone induced by bone-implant contact is also investigated to provide insights to commonly observed clinical complications. This work combines nano or micro scale experiments measurements of mechanical properties with analytical and computational models that enabled the prediction of contact mechanics at the micro and macro-scales.
