摘要：

本文提出一种无牙颌种植修复的数字化流程。使用三维（3D）打印的个别托盘和哥特式弓获取与患者软组织最佳匹配的印模及正中关系记录。将锥形束计算机断层扫描，容积数据、印模数据和3D面部扫描数据叠加后，用颅面硬组织、口内软组织和口外面部轮廓创建一个3D虚拟患者。在3D虚拟患者的指导下，以正确的正中关系和数字化微笑设计进行虚拟排牙。所有数据可以在2次临床就诊中采集完成，从而在第3次就诊完成种植手术及临时修复，实现可预测的功能和美学修复。

关键词: 无牙颌种植修复, 数字化流程, 正中关系, 面部扫描, 计算机辅助设计和计算机辅助制造

Abstract:

This clinical report proposed a digital workflow for edentulism implant rehabilitation. 3-dimensional (3D)-printed individual trays and Gothic arch were used to obtain optimal fit with the patient’s soft tissue and centric relation recording. A 3D virtual patient was created with craniofacial hard tissue, intraoral soft tissue and extraoral facial profile after data superimposition of cone beam computed tomography (CBCT) volumetric data, scanned impression data and 3D extraoral facial scan. Tooth alignment was performed in correct centric relation and virtual smile design under the gui-dance of 3D virtual patient. All data could be collected in only two clinical appointments. Computer-guided implant surgery and computer-assisted design and computer-assisted manufacturing (CAD/CAM) interim prostheses were finished, allowing functional and esthetic rehabilitation in a predictable way.

Key words: edentulism implant rehabilitation, digital workflow, centric relation, facial scan, computer-aided design and computer-aided manufacturing
