The aim of the present study was to describe a proof of concept digital workflow for the implant-prosthetic treatment in partially edentate patients and evaluate its clinical performance.
A 55-year-old woman with a Kennedy class III bilateral edentulism in the mandible has been selected for a computer guided implantology according with the Smart Fusion® protocol (NobelBiocare, Kloten, Switzerland). After the template-guided implant placement, an immediate loading of the implants has been performed. QuickTemp conical temporary abutments were selected to deliver immediately prefabricated cement-retained provisionals. Two months after an impression was taken with an intraoral digital scanner (3Shape Trios3, Copenhagen, Denmark). The provisional restoration optical scanning was used to transfer the functionalized prosthetic contour to be duplicated into the definitive porcelain fused to zirconia restoration cemented on customized titanium abutments.
A satisfying esthetic and functional result has been achieved. No biological and mechanical complications were recorded.
The investigated fully digital implant-prosthetic protocol provided a smooth, complication free and time effective treatment alternative to the conventional workflow. Besides the fully digital workflow allowed the surgical and prosthetic decision making and the communication within the dental team and with the patient. Further improvements heading to a direct match between the intraoral scan and the CBCT are strongly advised in order to create the so-called virtual patient.
本研究旨在描述一种用于部分牙列缺损患者种植修复治疗的概念验证数字工作流程，并评估其临床性能。
选择一名55岁下颌双侧Kennedy III类牙列缺损的女性患者，按照Smart Fusion®方案（诺贝尔生物科技公司，瑞士克洛滕）进行计算机引导种植术。在模板引导下植入种植体后，立即对种植体进行加载。选择QuickTemp锥形临时基台以立即交付预制的粘结式临时修复体。两个月后，使用口腔内数字扫描仪（丹麦哥本哈根3Shape Trios3）取模。临时修复体的光学扫描用于将待复制的功能化修复体轮廓转移到粘结在定制钛基台上的最终氧化锆全瓷修复体中。
获得了令人满意的美学和功能效果。未记录到生物学和机械并发症。
所研究的全数字化种植修复方案为传统工作流程提供了一种顺畅、无并发症且高效的治疗选择。此外，全数字化工作流程有助于手术和修复决策以及牙科团队内部和与患者之间的沟通。强烈建议进一步改进，以使口腔内扫描与CBCT直接匹配，从而创建所谓的虚拟患者。
