Design outcomes

Primary

MeasureTime frame
Passivity of verification jig measured as marginal gap at the abutment verification jig interface using triple-scan protocol and 3D superimposition analysis Timepoint: Outcome will be assessed after healing and placement of multi-unit abutments, at a single time point during verification jig placement. Assessment will be performed intraorally using the one-screw test and immediately followed by digital evaluation using the triple-scan protocol and 3D analysis
