摘要： 本文报道1例牙列缺损伴张口受限患者的可摘局部义齿数字化修复流程。患者因张口受限,传统托盘取模难以完成,采用数字化口内扫描获取口内软硬组织数字化印模,通过计算机辅助设计和3D打印技术制做诊断义齿,使用诊断义齿制取闭口式精印模及确定咬合关系,选择性激光打印技术完成金属支架制作,患者对修复效果满意。本病例对于张口受限、小口畸形的牙列缺损或缺失患者修复流程提供新的治疗思路。

Abstract: This paper reports on the digital restoration procedure of removable partial denture for a partially edentulous patient with limited mouth opening. The traditional tray impressions were difficult to complete for this patient. A digital intraoral scan was used to obtain digital impressions of the intraoral soft and hard tissues, and a computer-aided design and 3D printing technique were used to manufacture the diagnostic denture. The diagnostic denture was used to make final impressions and occlusal relationships and selective laser melting technology was used to produce a metal framework. The patient was satisfied with the restorative. This case provides a new way of thinking about the restorative process for partially edentulous patients with limited mouth opening.

Key words: limited mouth opening, removable partial denture, intraoral scan, diagnostic denture, selective laser melting
