partial function And esthetics and help
Stabilize grafted tissue,1,2 as Well as
shape gingival contours.
Digital methods involving the pick-up
technique and a pre-milled crown and
the chairside process of computer-
aided design and computer-aided
manufacturing (CAD-CAM) based on
the postoperative intraoral scan have
been reported for fabricating the
immediate implant-supported interim
restorations.
