Developing customized implants with successful bone integration is important for dental, maxillofacial, and orthopedic care in**Ontario. Liburdi has a unique direct energy deposition (DED) based additive manufacturing (AM), or 3D printing, technology that**can be further developed to efficiently produce highly customized/personalized implants on demand.**While metallic implants have become common place in dentistry and joint replacement surgeries, between 10-15% of orthopedic**and 2% of dental implants that bond to bone still fail in service within 20 years. In addition, many patients had infections from the**surgical procedures or during recovery. These problems demonstrate the need for novel surface modification processes optimized**for the additive manufacturing of metallic implant applications.**This project aims to develop new surface modification techniques that are compatible with Liburdis direct energy deposition**based AM technologies. The proposed project will focus on surface modification approaches that will 1) selectively produce**advanced surface morphology by laser machining for improved osseointegration; and 2) reduce post-surgery**infection/inflammatory response using polymer based surface modification. Integration of such technology development with**customized implant design, implant production, surgical planning, and post-surgery management will lead to a complete medical**implant solution, which will lead to a new product by Liburdi and ultimately benefit implant recipients.**.**Ontario

在安大略省**中，开发具有成功骨整合的定制植入物对于牙齿，颌面和骨科护理很重要。 Liburdi具有独特的直接能量沉积（DED）添加剂制造（AM）或3D打印，可以进一步开发**可以有效地生产高度定制/个性化的植入物。此外，许多患者感染了**外科手术或康复期间的感染。这些问题表明，需要优化新型的表面修饰过程**用于金属植入物应用的添加剂制造。拟议的项目将集中于表面修饰方法，1）通过激光加工选择性地产生**高级表面形态，以改善骨整合； 2）使用基于聚合物的表面修饰来减少手术后**感染/炎症反应。将这种技术开发与**定制的植入物设计，植入物生产，外科计划和手术后管理的整合将导致完整的医疗**植入解决方案，这将导致Liburdi的新产品，并最终使植入物受益者受益。
