An implant-based, telescopic bridge should be viewed as the treatment of choice for the rehabilitation of an edentulous mandible (Abd El-Dayem et al., 2009). This is the conclusiondrawnfromtheresultsofaninvestigation by Eitner and his colleagues in 2008, especially in anatomically difficult situations, in which an im- plant-supported superstructure guarantees an ade- quate prosthetic rehabilitation. Visser et al. showed in 2009 that the implant-supported restoration of the edentulous maxilla also represents a proven and effectivetreatmentmethodwithpredictablesuccess. _Connection elements Various anchoring elements such as bars, double crowns and a variety of prefabricated connection elements for the replacement of teeth have been discussedinthepast(Alfaddaetal.,2009;Eitneretal., 2008).Abarconnectionandtelescopiccrownsarefa- voredfortheedentulousmaxilla,since,incontrastto flexible connections, these can prevent the denture CAD/CAM-based restoration of an edentulous maxilla Author_Dr Arnd Lohmann, Germany 20 I CAD/CAM 3_2012 Fig. 1 Fig. 2 Fig. 3 Fig. 4a Fig. 4b
