(A) The alignment tools attached to orient the prefabricated SynCone abutments with a parallelometer in the laboratory. (B) The resin key is used to record the desired abutment relationships before transferring this relationship into the mouth. (C) The resin key and abutments are transferred into the mouth (this shows a fixed partial-denture resin key). (D) Clinical view of SynCone abutments after being transferred into the mouth. (E) The precision prefabricated matrices (telescopic matrices) are positioned over the abutments (they are not attached to the abutments; frictional retention retains them in their place). (F) The custom-cast splinting frame for the overdenture is cemented over the matrices. (G) Final impression with splinting frame. (H) Final clinical view of completed telescope overdenture
