| industry report Digital workflow: From planning to restoration Drs Jan Kielhorn, Siegfried Hoelzer & Björn Roland, Germany High-quality treatment results that are individual to each patient can be drawn up for the edentulous jaw in the combination of innovative procedures for implant surgery and reasoned prosthetic concepts. In this article, the authors describe the digital workflow for the tried- and-tested immediate restoration concept SKY fast & fixed and discuss the possibilities of transverse screw- ing, amongst others. Fig. 1: Transverse screwing: the thread for the bolt screw is located in the bridge framework. The bolt screw (A) and the cylindrical surfaces (B and C) form a unit. The prosthetic coping is fixed as a three-point fixation using the bolt screw and the short cylindrical surfaces. Due to the short cylindrical surfaces, the coping locks itself once attached. Introduction Digital technologies help simplify the process involved in implantology and often accelerate the process, whilst at the same time offering a high level of accuracy. High-pre- cision results can be achieved in an efficient manner by combining the digital production of the superstructure. In addition to digital know-how, proven fundamentals are promising factors. This includes patient compliance, a sound dental and dental technical knowledge, surgi- cal and manual skills, the perfect materials and products and close consultation within the treatment team. On the basis of this, modern computer-guided procedures offer an optimum basis for re-interpreting tried-and-tested im- plant prosthetic concepts such as the SKY fast & fixed (bredent medical). This article shows the digital workflow using a patient case as an example. Anchoring The “fixed” treatment option has become important for edentulous jaws and jaws that are becoming eden- tulous. Many patients state that they are not satisfied with the classic removable total prosthesis; in particular, if they lose the last few teeth they still have. They want an aesthetic, functional implant prosthetic restoration. However, areas of limitation, such as suboptimal ana- tomical circumstances, are often encountered. In order to be able to avoid bone augmentation, measures where Fig. 2 Fig. 3 Figs. 2 & 3: Initial situation: conventional X-ray measurement (two-dimensional) and situation model. 26 CAD/CAM 1 2018
