Digitalization of edentulous areas restored with dental implants is still considered a demanding procedure, mainly because of the lack of fixed reference landmarks, together with an increased interimplant distance. To overcome such limitations, an auxiliary device is introduced with the 3-fold purpose of stretching the soft tissues with a fixed object connected to the scan bodies, creating areas with nonhomogeneous architectures between the implants, and shortening the interimplant distance with the interposition of solid geometric figures. The rationale was to increase the accuracy of digital scans in a cast-free digital implant workflow.
数字化无牙颌区域修复仍然被认为是一项具有挑战性的操作,主要是因为缺乏固定的参考标志点,同时种植体之间的距离增加。为了克服这些限制,引入了一种辅助装置,具有三重目的:用连接到扫描体的固定物体拉伸软组织,在种植体之间创建具有非均匀结构的区域,并用固体几何图形插入来缩短种植体之间的距离。其基本原理是在无托槽数字化种植体工作流程中提高数字化扫描的准确性。
