摘要/Abstract

摘要：

牙科氧化锆陶瓷凭借其优良的性能在口腔修复领域得到广泛应用。目前主流制备技术是采用CAD/CAM技术,在CAD/CAM数控加工阶段,氧化锆预烧结体超过80%的体积在加工后成为废弃粉体,造成资源的巨大浪费,需要寻找可行的工艺路线,使废弃的氧化锆粉体能够再生利用。本文围绕牙科氧化锆陶瓷废弃粉体再生利用,从牙科氧化锆陶瓷CAD/CAM制备工艺,废弃氧化锆的除杂工艺,氧化锆粉体的研磨、成型、烧结、性能评价以及再生氧化锆陶瓷的生物相容性评价等方面进行综述,为推动废弃粉体再生利用和构建牙科陶瓷绿色制造提供参考。

Abstract:

Dental zirconia ceramics have been widely applied in the field of oral restoration due to their excellent performance. The current preparation technology involves CAD/CAM manufacturing process. During the CAD/CAM machining stage, over 80% of the volume of zirconia pre-sintered blocks is removed as waste powder, leading to significant resource wastage. There is an urgent need to explore feasible technical pathways to recycle and reuse this waste zirconia powder. This paper reviews the recycling of waste dental zirconia powder, covering aspects such as CAD/CAM processes, purification of waste zirconia, powder grinding, forming, sintering, performance evaluation, and biocompatibility of recycled zirconia ceramics. The aim is to provide references for promoting the recycling of waste powder and establishing a green manufacturing system for dental ceramics.

Key words: dental zirconia ceramics, CAD/CAM technology, waste powder, recycling, performance evaluation
