This case report presents the integration of a digital facially driven prosthetic plan to the computer-assisted implant planning for rehabilitation of edentulous arches.
Diagnosis of edentulous arches is hampered by the lack of intraoral references. However, a digital facial profile analysis facilitates the treatment plan, taking into consideration the harmony among teeth, lips, and face to restore a pleasant smile.
The first appointment consisted of digital documentation including intraoral scans, facial scans, and photographs. Based on these data, a smile frame was created to guide the digital wax-up. Cone-beam computed tomography (CBCT) scans were merged to facial and intraoral scans to perform the virtual surgical planning. Integration between facial, intraoral, and bone tissues were used as a reference to define implant position and prosthetic planning. The digital planning was integrated into the surgical procedure using stackable templates, and an immediate loading was performed. The interim prosthesis was manufactured based on the digital wax-up. With digital data, quality control could be performed to evaluate the esthetic outcome of the treatment.
An esthetic and functional rehabilitation was possible using the respective digital workflow to define harmony between a smile and facial tissues.
A digital treatment implant planning can be conducted considering patient's individual needs to improve the esthetic outcome.
本病例报告介绍了将数字化面部驱动的义齿计划整合到计算机辅助种植规划中，以恢复无牙颌。
无牙颌的诊断受到缺乏口内参考的限制。然而，数字化面部分析有助于治疗计划，考虑到牙齿、嘴唇和面部之间的和谐，以恢复愉快的笑容。
第一次就诊包括数字化记录，包括口内扫描、面部扫描和照片。基于这些数据，创建了一个微笑框来指导数字化蜡型。锥形束计算机断层扫描（CBCT）扫描与面部和口内扫描融合，以进行虚拟手术规划。将面部、口内和骨组织之间的整合作为参考，以确定种植体的位置和修复计划。数字化规划通过可堆叠模板整合到手术过程中，并进行即刻负载。根据数字化蜡型制作临时修复体。通过数字数据，可以进行质量控制，以评估治疗的美学效果。
使用各自的数字化工作流程定义微笑和面部组织之间的和谐，可以实现美观和功能的修复。
可以根据患者的个体需求进行数字化治疗种植计划，以改善美学效果。
