摘要
4D打印通过结合时间维度,实现刺激响应形状或行为变化,从而改进了传统的3D打印。生物智能材料对这项技术至关重要,它使可编程的转换在生物力学和牙科领域具有巨大的潜力。这篇综述探讨了智能材料和刺激在4D打印中的应用,重点是牙科应用。通过EMBASE、Web of Science、MEDLINE、Cochrane Library和临床试验注册库进行全面搜索,确定了154篇关于4D打印技术、生物材料和与牙科应用相关的刺激的文章。其中84项与审查目标相关,其中25项专门关注4D打印和各种智能材料。该综述重点介绍了用于可编程响应的生物材料,如形状记忆聚合物、形状记忆弹性体、响应墨水和水凝胶。这些材料能够创造出能够适应、自组装或响应温度、湿度或pH值等刺激的结构。在牙科方面,这些能力显示出在正畸、种植体和组织工程方面的应用潜力。4D打印和生物智能材料的集成有可能通过创建自适应的、时间响应的结构来改变牙科。这项技术可以实现个性化、精确和微创治疗,解决牙科护理中复杂的生物力学挑战。
Exploring the 4D printing linked bio-smart materials in dentistry: a concise overview.
4D printing advances traditional 3D printing by incorporating the dimension of time, enabling stimuli-responsive shape or behavior changes. Bio-smart materials, crucial to this technology, enable programmable transformations with significant potential in biomechanics and dentistry. This review explores the use of smart materials and stimuli in 4D printing, emphasizing dental applications.A comprehensive search across EMBASE, Web of Science, MEDLINE, Cochrane Library and clinical trial registries identified 154 articles on 4D printing technologies, biomaterials, and stimuli relevant to dental applications. Of these, 84 were pertinent to the review's objective, with 25 specifically focused on 4D printing and various smart materials. The review highlights biomaterials engineered for programmable responses, such as shape memory polymers, shape memory elastomers, responsive inks, and hydrogels. These materials enable the creation of structures that can adapt, self-assemble, or respond to stimuli like temperature, moisture, or pH levels. In dentistry, these capabilities show potential for applications in orthodontics, implants, and tissue engineering.The integration of 4D printing and bio-smart materials has the potential to transform dentistry by creating adaptive, time-responsive structures. This technology enables personalized, precise, and minimally invasive treatments, addressing complex biomechanical challenges in dental care.
