Abstract：
Treatment planning for the transition of patients from terminal dentition to full-arch implant rehabilitation poses challenges. Such challenges pertain to achieving the new orientation of the occlusal and esthetic plane as well as the change of vertical dimension of occlusion (VDO), while the fixed provisionalization using a digital workflow still tends to be considered complex and hard to perform. This article illustrates step-by-step the utilization of a digital workflow protocol in the treatment planning for rehabilitation of terminal dentition patients, simplifying the smile design and ensuring that fixed provisionalization serves both functional and esthetic requirements. This protocol includes facially driven, three-dimensional (3D) digital smile design and chairside mock-up restoration workflows that enable prosthetically driven assessment prior to implant treatment planning and 3D printing of surgical templates and prefabricated interim prostheses, which can predictably reduce chairside time and adjustments at the surgical and fixed provisionalization appointment.
摘要：
患者从末端牙列过渡到全牙弓种植康复的治疗计划提出了挑战。这些挑战与实现咬合和美学平面的新方向以及咬合垂直尺寸（VDO）的变化有关，而使用数字工作流程的固定置备仍然倾向于被认为是复杂且难以执行的。本文说明了在治疗计划中逐步使用数字工作流程协议，以康复晚期牙列患者，简化微笑设计，并确保固定的预置满足功能和美学要求。该协议包括面部驱动，三维（3D）数字微笑设计和椅旁模型修复工作流程，可在植入治疗计划和手术模板和预制临时假体的3D打印之前进行假体驱动的评估，可以预见的是，这可以减少手术和固定备用金任命时的主席时间和调整。
