| 乳磨牙的过早丧失是儿童口腔临床中常见问题，极易引发牙弓长度缩短、继承恒牙阻生及牙列拥挤等错颌畸形。科学有效的间隙管理是预防性正畸的核心内容。传统间隙保持器存在制作繁琐、精度不足及易引发牙周病变等局限性。近年来，以计算机辅助设计与制造（CAD/CAM）及3D打印为核心的数字化技术为间隙管理带来了革新。本文立足于乳磨牙早失的临床需求，系统阐述了数字化3D打印技术在间隙管理中的应用基础与核心工作流程。文章探讨了三维数字模型的获取、个性化拓扑优化设计、选择性激光熔化（SLM）等关键打印技术及材料学特征，总结了该技术在实现精准适配、提升生物力学性能与改善患者舒适度等方面的临床优势。针对当前存在的成本、技术门槛等问题进行剖析，展望人工智能辅助设计、新型生物材料及多功能整合的未来发展趋势，以期为临床医生制定精准化、个性化的儿童间隙管理方案提供理论依据。 |

| Objective The premature loss of primary molars frequently leads to shortened dental arch length,impaction of succedaneous permanent teeth, and dental crowding.Effective space management constitutes a core component of preventive orthodontics.Traditional space maintainers have limitations such as cumbersome fabrication,insufficient precision,and susceptibility to periodontal issues.Recently,digital technologies centering on CAD/CAM and 3D printing have revolutionized this field.Based on clinical demands,this article systematically reviews the application of digital 3D printing in space management.It discusses in detail the acquisition of digital models,personalized topology optimization, selective laser melting (SLM) techniques,and material properties.The clinical advantages of 3D-printed maintainers, including precise adaptation,enhanced biomechanical performance,and improved patient comfort,are comprehensively summarized.Finally,the article analyzes current challenges such as cost and technical barriers,and outlines future trends involving AI-assisted design,novel bioactive materials,and multifunctional integration,to provide a theoretical basis for precise and personalized space management. |
