Digital technologies have not only revolutionized workflow strategies for implant- supported fixed prostheses but also changed preferences in the choice of restoration retention. Owing to the effortlessness of developing workflows with digitalization, screw-retention has become favored for initial prostheses. However, cement retention is still indicated for cases in which abutment reuse is needed for replacing failing restorations with technical complications.
In this case report, a modified digital workflow is described for treating an impaired occlusal relationship. A dual-scan approach for an abutment-level digital implant impression to remake a cement retained implant supported fixed restoration is defined in detail.
Clinicians can highly benefit from the presented strategy, which offers an efficient digital workflow to simplify cement-retained abutment level impressions through the use of an intraoral scanner. Exchanging intra- and extra-orally surface scanned abutment data may become an option in complete digital model-free workflows for addressing problems related to cement-retained implant supported fixed prostheses.
数字技术不仅彻底改变了种植体支持的固定修复体的工作流程策略，还改变了修复体固位方式的选择偏好。由于数字化技术能够轻松地开发工作流程，螺丝固位已成为初始修复体的首选。然而，在需要更换因技术问题而出现故障的修复体时，仍需要采用基台重复使用的粘接固位方式。
本病例报告介绍了一种改良的数字化工作流程，用于治疗咬合关系受损的病例。详细描述了一种用于制作粘接固位种植体支持固定修复体的基台水平数字化印模的双扫描方法。
该策略为临床医生带来了很多益处，通过使用口内扫描仪，为简化粘接固位基台水平印模提供了一种高效的数字化工作流程。在完全数字化、无模型的工作流程中，交换口内和口外表面扫描基台数据可能成为解决与粘接固位种植体支持固定修复体相关问题的一种选择。
