consuming than making them on the metal frame- work itself, and it was then possible to transfer them directly to the final framework. Furthermore, the mock-up almost “splinted” the electroformed gold copingsduringtheimpression,allowingfortheexact transfer of the abutment position. At the same time, the vertical height and interocclusal relationship were recorded. The delivery of a milled temporary restoration permitted a slow and non-progressive loading of the implants, which then leads to bone re- modeling.16 Abutments were left in place after mounting. Combined with the fabrication of a new cast, this further decreased the risk of inaccuracies during the transfer process. _Conclusion The method described here can be used for full- arch restorations with both fixed and removable im- plant supported dentures. Accurate impressions can be accomplished and occlusion, vertical dimensions, as well as implant positions can be transferred while facilitating the full-arch restoration process. In addi- tion, this technique resulted in a reduction of the re- quired chair time Disadvantagesofthistechniquelieinthefactthat the quality of laboratory technician’s work meets higherdemandsthanusual,andthattheclinicianalso needstoacquiresomeadditionalskills.Furtherdisad- vantagesofthismethodincludetheneedforahighly qualified technical lab and higher technical costs rel- ativetothoseassociatedwithprefabricatedtitanim- plant abutments.
