I case report _ full-arch restoration _In dental implantology, the optimal and truly passive fit of the framework is essential for the long- term success of a restoration owing to the physiology of bone tissue around implants. For a multiple-unit implant-supportedrestoration,thetraditionalpouring techniqueisrathercomplexandchallenging.Thediffi- culty of achieving a passive fit is directly correlated to the number of components used and the volume oftheframework.CAD/CAMtechnologyprovidessuch a high level of accuracy that it has revolutionised the fieldofrestorativedentistry. Today, many implant manufacturers collaborate with industrial companies to develop state-of-the- art machining solutions for their implant-supported frameworks. In that regard, the concept developed by Simeda (Anthogyr) is innovative and supported by many years of proven success in the fabrication of CAD/CAM dental restorations. The major advantage ofCAD/CAMtechnologyisthatitguaranteesahighly accurateandpredictablefit(<10µ).Thisclinicalcase report demonstrates the high potential of this novel digital solution.
