Procedures with the SI. The reference virtual model captured with 7Series® (a) was used to design a SI (b). The SI was tried on the reference stone cast model (c) and therefore used to capture a physical impression (d) of the implant position with polyether (Impregum®). After hardening of the material, the SBs head were made free using a blade (e), the SBs were unscrewed and the SI was removed with all transfers inside. This SI was then turned and the implant analogs were carefully screwed into the SBs (f, g). Then the SI was used to pour a plaster cast (h, i). The implant SBs were not unscrewed and the SI was carefully detached, once again using a blade (j). The SI-derived cast (k) was scanned with a desktop scanner (D15®; Camcube, Montreal, Canada) (l)
