case report I provisionalcement(TempBond,KerrCo.,Orange,USA; Fig. 4b). In addition, a surgical stent fitting onto the abutments was milled from clear PMMA (Zenotec; Wieland, Pforzheim, Germany, Fig. 5a). The planned axis of implant #13 was determined using a dental parallelometer (Fig. 5b), and a drill sleeve was placed into the surgical stent (Fig. 5c). An implant (4.5 × 10mm,SBline;Dentegris,Duisburg,Germany)wasin- sertedwithatorqueof35Ncmusingatwo-phasepro- tocol(Fig.6).Threemonthsafterimplantplacement,an impressionpostwaspositionedontheimplantandthe surgical stent was placed in the patient’s mouth after thedrillsleevehadbeenremoved.Theimpressionpost wasattachedtothesurgicalstentusingmodelingresin (pattern resin, GC, Alsip, USA; Fig. 7).

A customised abutment fitting crown #13 was fabri- cated (Figs. 9a and b), positioned on the implant #13 andtorquedto35Ncm(Figs.10a–c).Subsequently,the denturewasinserted(Figs.11aandb). Case2 The patient (male, 61-years-old and in very good generalhealth)hadafoul-mouthperiodontal-implant and prosthodontic rehabilitation in 1998.

Thirteen years after prosthetic rehabilitation, the patient reported to the office with a root fracture in tooth#15.Thetoothwasextracted,thesecondarytel- escopic crown in regio #15 was removed, and the supraconstructionwastemporarilyfilledwithaphoto- cured,highlyelastictemporarymaterial(Fermit,Ivoclar Vivadent, Ellwangen, Germany). The patient again re- fused a sinus lift and therefore the immediate implant placement regio #15 was scheduled. The axis of the tooth #15, the fabrication of the transfer key and the implant placement, were performed as previously de- scribedincase1.Ashortimplant(Endopore4.1×9mm, Sybron Implant Solutions, Bremen, Germany) was in- serted into area #15 (Fig. 13).
