Abstract: In the restoration of removable partial denture，the precise preparation of the guiding plane is important for the retention and stability of removable partial denture. The guiding plane can also reduce the adverse stress of the abutment and avoid food impaction. How the prepared guiding plane can be ensured to be as parallel as designed one has always been a concern for clinicians. In view of the traditional guiding plane preparation cannot meet the needs of clinical precise treatment，digital combined with 3D printing technology is expected to solve the above problems on guiding plane preparation. Based on this，the author also proposes a multifunctional guide template with guiding plane preparation and implant implantation. With this novel template，the implantation and removable partial denture insertion can be completed simultaneously，which expands the application of guiding plane preparation with digital technology. This article elaborates on the application and development of digital technology in guiding planes preparation of removable partial denture，providing assistance for the clinical promotion and application of this technology.

摘要： 在可摘局部义齿修复中，导平面的精准预备对于可摘局部义齿的固位和稳定具有重要意义，还可减轻基牙受到的不良应力，减少食物嵌塞等问题发生。如何确保设计与预备的导平面具有相同平行度一直是临床医生关注的问题。鉴于传统导平面预备导板已无法满足临床精准治疗需求，数字化结合3D打印技术制备导平面预备导板有望解决上述问题。笔者在此基础上还提出了导平面预备-种植体植入的多功能导板，实现了种植体植入与可摘局部义齿戴入的同期修复，进一步拓宽了数字化导平面预备应用范畴。文章就数字化技术在可摘局部义齿导平面设计与制作中的应用研究进展做一阐述，为后期该技术在临床推广应用提供帮助。
